PC Power & Cooling Silencer MKIII Power Supply Unboxing & First Look Linus Tech Tips

[kght222]

a single strong rail just means you don't have a choice. more than one strong rail means that you have a choice. it also of course means that you have more parts in the ps that can fail. but i personally prefer 2 12 volt quality rails, efficiency goes down, but ability to run consistently at the max ratted wattage in the long term goes up.

[gunraykilla]

Power is current and current is measured in amps. so yes Overpower means over current.

[BassPounderX]

i hate when u look at pictures of a modular psu online but they don't show the fucken modular connectors so u know how modular it is or what connects

[PCandconsoleguy]

i wont his for my little setup of a core 2 quad with a gtx 500ti. but its white and every thing in/on my computer is black.

[HammerFET]

Power = current * Voltage

If you have over voltage protection, that means the voltage will never go too high. Therefore it must mean that in an over power situation, the current is what rises. But if it's over power protected, how can the current go too high if voltage is fixed... This implies the unit is also over current protected.

[Mimonome]

@jurassic512: I will take that all the name calling and anger signifies defeat.

[colinmaharaj]

There is a cable in the box, I saw it, what is it????????

[iattiladravecz]

Linus mate, the missing cable was in the box @ 4:50 lol :-)

[Elastane]

am sure I saw another cable in the packaging foam you never took out :P

[CraftableHuman]

the thumbnail pic makes it look like a toaster

[TurtleGuyHD1]

3:23 That's what she said lol

[Zwank36]

Over power will INCLUDE over current.

[hertzman5YT]

WTF. MODULAR PC POWER AND COOLING? WTF IS THIS?

[hertzman5YT]

Put this in the white 500R. Sexy times go.

[JonProce]

Power [Watts] = Voltage [Volts] x Current [Amperes], so at a fixed voltage, yes, over-power means over-current.

[LiveComputing]

All for not if we do not focus on Cyber Security

SEARCH YouTube for; Live Mediation and get on board

[imjansd]

when will we see the phantom 410?

[FatAssNigga97]

first look I thought this was a toaster

[ShadysFriend]

24 - pin = One Linus arm in length

[dark2koneko]

The was cable in the box when you moved it out of the way. So there were as many cables as the the power supply had ports.

[Ubertommy69]

In the thumbnail it looks like a toaster :P

[MegaLeedsfan1]

they should make linus arm a universally recognised measurement

[greysmoke321]

I love watching Linus pc videos on my iPhone, iMac, and friends' Mac Book :)

[ChipsAhoyCA]

@greysmoke321 max trollin

[SOAirsoftteam]

how much is this and where can you get it?

[DeadeyeDH]

I'm going to start using "Linus Arms" in my personal standard units of measurement lol

[TalesOfWar]

@DeadeyeDH Wonder if it'll get more use in the US than Metric? lol

[javelinxd44]

@DeadeyeDH it almost sounds like it could be a standard unit of measurement

[shashanksaxena92]

Hey Linus, you forgot a cable inside the box lol, @4:48

[shashanksaxena92]

Hey Linus, you forgot a cable inside the box lol, @4:48

[wsthoj]

WHATS up with the smarty pants up there......

[Determinatory]

Yes it does come with more cables :

2 x 4+4pin CPU +12V

3 x 4pin Molex

2 x 6+2pin PCI-E Power

1 x FDD Power

6 x SATA Power

[coldlettersofficial]

Linus, what happened to your finger? 0:55

[LEW1S1900]

Do an unboxing and review of the AMD Radeon 7990, looks so badass!!

[THATINDIAN1]

check out my build hope u guyz have some inputs for me

[TheFmLOL]

No CES 2012 video?

[grimsdayable]

is it just me or at 4:51 can you see another cable in on the foam in the box?

[ItsAReefer]

@grimsdayable at 3:26 Linus removes a strap from the fixed power leads and throws it into the box.

[LithianValkiyr]

I'm currently a student taking Electronics. I could be wrong, but wouldn't it make sense that "Over Short Circuit" means Over Current? Seeing as if you have a short circuit there would be no load to limit current and therefore have a theoretical unlimited amount of current?

[i4ittwasdis]

over power may mean overcurrent and overvoltage

[cronochos]

HOLY CRAP ON A CRACKER!!

[nervoustwitch77]

its nice to see you cant slip nothing past u guys,lol if anyone else would like bad info holla!

[Greenfire833]

Is that a Baby Crib i see there. 2:55

[juanantonyphoenix]

Could you please do an unboxing of the silverstone PS07

[marouanebenouzekri]

600 Watts enough for Graphics Cards?

[S13v7n]

@marouanebenouzekri

Depends what graphics card your looking at. For midrange to low range (say GTX 540-560) is sufficient.

GTX 570/580 or AMD 6870 etc recommend at least 500-550. To be safe, if your going with a high-end GPU, make the investment in a 800W, just to be on the safe side.

[marouanebenouzekri]

@S13v7n 6870 & GTX 460 enough?

[S13v7n]

@marouanebenouzekri

Again, to be on the safe side, get a little higher PSU, 700W to 800W, they are literally $30 to 50 more expensive.

You don't want to keep buying PSU everytime you make an upgrade, so get a decent one with lots of headroom for unforseen upgrades down the road. Play it safe.

[marouanebenouzekri]

OK. Tell me how much cost the GTX 590?

[S13v7n]

@marouanebenouzekri

The GTX is $700-800.

Unless your a enthusiast gamer, the very high-end dual GPU is probably overkill for you.

Get the GTX 580, or wait for 600 series, or get the 7870 for $500.

Also with your E8400, having such a highend graphics card wont be worth it (so current CPU will bottleneck its full potential.

I have an i7 930 with 5870, if I got the 5970 at the time, my 930 would still have been a bottleneck.

You would need a new system if you wanted high-end

[CloakedRhombus]

@marouanebenouzekri depends on the card

[marouanebenouzekri]

@CloakedRhombus Listen i'am gamer I love games like Crysis 2, Battlefield 3 & GTA. Can you advice me a Graphics Card works for me good and for future and works with Core 2 Duo E8400.

[mad87645]

@marouanebenouzekri AMD 6870 IMO if your on a budget. Costs $150-200 and rocks all dx11 games on a decent resolution.

[S13v7n]

@marouanebenouzekri

To sum it up for you, Save your money for Ivy Bridge, if you don't plan on upgrading your CPU (E8400) anytime soon, anything like a GTX 580 / AMD 6870 is overkill since your CPU is bottlenecking your GPUs full potential.

If you want a good GPU for the future go ahead and get the GTX580/AMD6870/7870, but you need to be thinking of upgrading your CPU, otherwise by the time you upgrade your CPU, Haswell and GTX 700 / AMD 8000 will be out

Hope this helps.

[marouanebenouzekri]

@S13v7n Yes, thank you. The CPU can I Upgrade is Core 2 Quad Q9650 maximum watts for my motherboard 95W if I Upgrade this one better?

[S13v7n]

@marouanebenouzekri

Ok, so also mention this:

You have an older motherboard, so your limited to using the Q9000 series intel CPUs. They are still very good and capable CPUs for playing games at mid-high settings on a 1080p screen. But they are also not anything near a current i7's power.

Your best bet is to save money by getting a midrange card (you can get a discount on amd 6850/70 or gtx570 when the 600 series comes out)

No point getting a very pwoerful gpu when you...

[marouanebenouzekri]

@S13v7n Yes... I appreciate this thanks for your help! i7 of course is strong from LGA 755.

[S13v7n]

@marouanebenouzekri

Whats your budget and time-window you expect to upgrade?

Cause if it isn't for a while, forget current i7's. Wait for intel 3600K ivy bridge in mid 2012 or late 2012/early 2013 for intel haswell.

By that point in time, AMD/Nvidia will also release their entire line of 7000/600 cards and the current prices will drop.

(But then you may start hearing rumors of their next gen products )

[marouanebenouzekri]

@S13v7n I'm not sure now. I will buy the GTX 460 soon... My CPU I cannot change it now or Upgrade it. I've upgrade my RAM last day from 2 GB to 4 GB.

[S13v7n]

@marouanebenouzekri

...your current motherboard only supports a few years old cpu.

It would be better to save up money for a couple years to just buy a whole new computer (new mobo, cpu, gpu etc)

But an E8400/Q9650 with a midrange gpu like a GTX570 or AMD 6850/70 will still allow you to play upcoming games on high settings for quite a while (couple years at least)

I'm guessing that you likely have a GTX 9800 or 260 based on the current age of your CPU.

[marouanebenouzekri]

@S13v7n I know bro max TDP 95W

I have to Uprgrade to LGA 1155 or 1366 soon or maybe if I find the new one LGA 2011 not kidding.

[mota411]

@marouanebenouzekri yes it is it may be even enough for 2 gpu's running off one system.

[buckeyeg99]

Your video cut of and said other computer shit.

[combatkila]

LINUS ANSWER MY QUESTION

THUMPS UP SO HE CAN SEE THIS

[RamoneTalarico]

I want a wireless power supply, a mini Tesla coil beaming energy to my components....wire management a thing of the past,...and im sure would look sick through a case window. and in case your wondering, YES i am a geek

[udontseemebutiseeyou]

your sx850 you had on your test bench forever has 4 pci-e connectors on the backside of the psu, yet only 2 connectors

[shoda07]

Looks nice. 

[l3E7Studios]

Unbox the Kingwin STR-500 power supply! The best fanless power supply for desktop usage there is!

[KiruzA42]

Engineer here. Ohm's law can be manipulated such that P (power) equals the square of i (current) times r (resistance). Since resistance is a constant, power is directly proportional to the square of current and, therefore, overcurrent protection could be called overpower protection.

[TomHartill]

@KiruzA42 - Thanks!

[TheMaristBoy]

@KiruzA42 what kind of engineer are you?

[gokilofazza]

@TheMaristBoy Electrical engineer by the sounds of hit.. however any basic electrician should know anything and everything about ohms law.

Alot of engineering branches know ohms law too.

[TheMaristBoy]

@gokilofazza Why am I getting a feeling that there are a lot of electrical engineer students on the internet xD I just love electronics 

[MovieDirectorUncut]

@KiruzA42 Grade 11 Physics... comes in useful

[TheDokdek]

Hmm, would this fit in a 600t?

[dynetrax]

Why are there so many immature punks fighting all over the comment section of a power supply unboxing video? lol

[swedishgodkiller]

@LinusTechTips ur USA link is not right. U provided a dead link. If u remove the w and add us; u will have fixed ur problem

[ambrodji]

From looking at "Da Vinci" body anatomy principle one arm is about 44% of the length of the body.

So if Linus is 180 cm tall, then: 180 / 100 * 44 = 79.2 cm (31.2") = Linus arm

Or you guys could just google something a little more up to date (more accurate).

[TheCoconutCookie]

@ambrodji thank you

[dimos47ki7]

@ambrodji actually if u stretch both hands to the left and to the right, the length between the fingertips is almost the same as your height. tryied this with alot of friends and it is true in most cases

[ambrodji]

@dimos47ki7 Yes, exactly.

That is what the Da Vinci body anatomy principle is; you should do a google search on it xD

[toonygamer2004]

@ambrodji

ha ha I think you might confuse some people with having the brackets on that math. (180/100) * 44. Or to make it simpler, 180 * .44 . Good thing your around to show the light to some :)

[gadgetguy99]

what is a good watege for a first gaming build

[ShadowwwLFS]

@gadgetguy99 single GPU - 500W, dual GPU - 750W, triple GPU - 1000W, quad GPU - 1200W.

[LouwrensStassen]

@gadgetguy99 You are going to have to look at all the components of your rig. They should all say somewhere what their typical power draw is. Add them all up and you should get a good idea of what you need. Although.. if you added up to 799W... don't buy a 800W PSU. Have some buffer and keep future upgrades in mind. So there's no one answer... it all depends on your build. Also don't over shoot with the PSU. A powerful PSU runs at lower efficiency at low power demands.

[LordAtrocities]

I love your tech reports and unboxings. You have educated me in leaps and bounds over the last year. Thank you.

[TheAllthatremains94]

@LinusTechTips The US link is broken, as someone has mistakenly added in "w.' right before "ncix."

[cheti1337]

0:12 thats what she said



[ShadowwwLFS]

tl;dr yet another re-branded SeaSonic M12II.

[Foxx6699]

Linus can you unbox a box filled with air please. I'd like to see that.

[austinXDFtw]

so 600 watt is the old 1250 watt?

[Excaliza]

You should convert Linus arm span into inches/centimeters :D

[ice9sydas]

WATER COOLING PART 3 !

[gutrenchladd]

also is there any chance of you maybe adopting a rating system for your products? like a 1-10 or a 1-100 rating system that focuses execution of the products features in design? just curious...

[Peanutsreveng3]

Less cables than sockets?

Outstanding, especially when the cables probably cost 10p to produce!

Think I'll avoid that cheap POS PSU then.

[AndImObama]

@Peanutsreveng3 PC P&C is up there with SeaSonic as the best PSU makers.

They're not cheap at all.

[Peanutsreveng3]

@AndImObama

indeed, they do have a good name, which is why I watched it, but it's still a cheap PSU.

Bronze rated... yea ok... one cable less than there are sockets... stupid and in the league of cheap POS

[ShadowwwLFS]

@Peanutsreveng3 >SeaSonic

>cheap POS

nope. That's not how this world works.

[Peanutsreveng3]

@ShadowwwLFS I didn't say Seasonic are cheap POS, I said this PSU being review seems like one.

Seasonic are my prefered PSU brand.

[ShadowwwLFS]

@Peanutsreveng3 uhm well this PSU is basically a re-named SeaSonic S12II / M12II, just like Antec's HCG-series, few Corsair PSUs etc.

[gutrenchladd]

Linus in your opinion or in your fans opinions what is the best overall powersupply in the 700-800w range.... taking into account it should be modular.... have good length on cables... a good size fan... and not horribly priced.... any suggestions?

[daveyboytellem]

@gutrenchladd coolermaser silent pro gold 800w.... i never hear it over my other fans and it doesnt get hot... i got it on blackfriday and it was like $115

[piskooooo]

@gutrenchladd corsair ax/hx series

[ShadowwwLFS]

@gutrenchladd SeaSonic X750 / X850.

It's same as Corsair AX but just a fraction cheaper.

[TheInCreDIblEMaReKU]

Autocorrect...

[TheInCreDIblEMaReKU]

Hey Linux, when did you start out with computers?

[yassarikhan786]

@TheInCreDIblEMaReKU Dude, he's not an operating system.

[yoto5951]

how long is 1 linus arm xD?

[SirRaindrops]

toaster

[Martinx88813]

Nice PSU but my favorite color is black...

[PlayingThisGame]

2:14 I'd be a bit miserable if I bought this PSU and they weren't...

[MrPilotGunner]

Is there black version? links not work

[jack99889988]

Yes, the unit is one cable less.

[Ideeem]

kay buddies, power depends on voltage and current (and others things but we dont care) we all know it.

What happens when you limit only wattage? you can have too high current and very low voltage or too high voltage and very low current, no good for your security.

What happens when you limit current and voltage but no wattage? You ll be safe but if your PSU cannot deliver this amount of wattage, gonna have some issues.

Conclusion, it's OK to limit those 3.

[AniAddictDaisuken]

"One Linus arm in length" -xDD

[xXH3ll5xB3llXx]

Power = Voltage x Current (P=VI)

If it has over voltage and over power protection then the current must be at safe level

[humanitysonlyhope]

I don't know if you are aware but latley all your videos get the last second oc audio cut off so you always seem to end with "don't forger to subscribe for other com...

[jakehall331]

also linus could you measure your arm some time, so we get the measurement for future reference :P

[jakehall331]

i imagine over power is wattage which is a function of voltage and current

[TheLawnWanderer]

i have a dream, my dream is to build a pc 12 volt rail from an toroidal transformer with alot of capacitors to get the even voltage that it needs.

[TheIrredeemable]

OCZ ruined PCP&C.......

[samworkshop]

@TheIrredeemable , yes but supposedly that PCP&C has a Seasonic block

[ssoele]

Linus, yes, over-power protection is the same as over-current protection.

[MastergamerPatrick]

Hey Linus at me the US-Link is bronken ;-)

[fanicafanica]

He not left the cord folk he say this psu dont came with all cords becuase the ifficials from silencer waere make a mistake or something...

[TopsuLoL]

Lol, it's not like the 7970 isn't important like a watercooling part 2, tho.

[MyKingDodo]

A Linus arm needs to be an official unit of measurement.

[jabasoo]

@MyKingDodo shhh don't let the iphone hear you say that!

[attilagenius94]

@MyKingDodo if it were England in the middle ages it would be

[iNekoNaru]

@MyKingDodo Incredibly inaccurate.. D: as his arm's grow and shrink over time. :D

[GITSProductions]

Current is the flow of electrons along a conductor, so ya I supose it could mean a form of power serge protection. Nice power supply, looks real clean.

[aka08lewman]

@GITSProductions

Anyone who doesn't know what current is shouldn't be near this Youtube channel or a Pc, But yes, it does mean OCP.

[jarskiXD]

When are you going to do a review of the 7970?

[nervoustwitch77]

yes over power is over current since current is power

im an electrican

[finbenton]

@nervoustwitch77 its not the same

[xXclemouneXx]

@nervoustwitch77 Current is NOT power. Electrical current is the flow of electrons in an electric conducting medium; just like a water current is a flow of water. Power is measured in Watts and current is measured in amps. I think what they mean by 'overpower protection' is a sensor that measures the wattage of the system rather than the intensity of the current to turn off the unit in case of an overload. Wouldn't like to have you as my electrician... Even I know better.

[nervoustwitch77]

@xXclemouneXx roflmao i new it wouldnt take long i love it when u geeks correct everyone lol its a nerd rage i have come to love i think it gets me off!

[ImAKillZoneFan]

@nervoustwitch77 fail

[ali1997ali]

where is the cat /.?

[DecodeAGamer]

Something thats currently confusing for myself, I have a PCI-e power cable running from my power supply (running from the same area as the 24-pin Motherboard power cable), I also have two additional modular PCI-e connectors.

I'm using the Coolermaster 800W Silent Pro Gold, does anyone know which PCI-e cable I can use? As I'd like to use the one that isn't modular... still to this day I'm clueless as to what power connectors I actually need to use, or can use.

Anyone got any insight on it? x.x

[DecodeAGamer]

@DecodeAGamer little bit of addtional information, it's to power a 6950 2GB Graphics card.

[007burrt]

1 linus arm in length , wow it seems i gotta learn measurement standards for pc building XD

[DecodeAGamer]

Some people use metric, some people use imperial, Linus? Uses... Linus™

[lynxloco]

can you lava cool one?

[GAKtion64]

YO FREIND ELRIC IS SEARCHIN 4 U.

[LouwrensStassen]

well... if my memory serves me correct... power = voltage X Current. So over-power protection would include both over-voltage and over-current protection... thumbs so Linus can see?

[cal920c]

@LouwrensStassen If that's all that's in your memory, then you goina need more, btw, you need to ram a girl

[LouwrensStassen]

@cal920c awesome comment!

[ShadowwwLFS]

@cal920c fun fact: skipping school/college does NOT makes you cool, contrary to popular belief.

[cmdstraker]

@LouwrensStassen Since one is dealing with a 2 or 3 different voltages it means overpower is the same thing 

[LouwrensStassen]

@cmdstraker I don't understand what you're saying... Means the same thing as what? If over-power protection means the same as over-voltage protection for different voltages... it would still just be over-voltage protection since it's just protecting the rails from outputting more that its specification... what ever that voltage is specified as for that particular rail. If voltage is constant and current increases, so does power (P=IV) so over-power protection also needs to look at current.

[cmdstraker]

@LouwrensStassen What I meant to say is that since you are dealing with a few fixed voltage output values overcurrent protection is the bigger deal.Therefor overpower protection really is overcurrent protection. Usually a voltage ripple on the input of about 5 percent is considered normal.

[ShadowwwLFS]

Isn't over-power protection monitoring power consumption on whole power supply?

I mean, if total power is e.g 1000W but 5V rail is e.g. 200W, then over-power protection won't shut power supply down if power draw _from 5V rail_ is 300W, while over-current protection would cause it monitors each rail individually.

[LouwrensStassen]

@ShadowwwLFS The total power output of a power supply unit is the sum of all the power outputs of the rails. Just because the PSU is rated at 1000W, it doesn't mean one rail can supply that. So you will need over power protection for each rail since each rail has its own power output limit.

[joeyf504327]

@LouwrensStassen wattage = volts X amps, amps=watts/volts, volts=watts/amps

[LouwrensStassen]

@joeyf504327 and wattage = power.... amps = current..... thanks....

[joeyf504327]

@LouwrensStassen i was just putting it in correct terms is all as power is a very general term

[PotadoTomado]

I like how the Linus Arm is becoming a standard unit of measurement.

[rmb1993]

Well the term "power" in physics and engineering has watts as the units. So "over power protection" would mean it will not go over the rated wattage.

[imjansd]

Hey linus,

Could u do a unboxing of the lc power prophecy v2 750w power supply

[Chainzaw1447]

Can it power a 7970?

[hokko1]

@Chainzaw1447 yes

[ShadowwwLFS]

@Chainzaw1447 It can power two 7970's.
