[TheSaltysack]

hey is a 550w psu good for asus mtherboard 4 gb ram 500hd 95w his readeon ice 1gb and 955 quad 3.2 will this psu be good for my pc build or am i bottlenecking it plz let me know asap i want to order my pc but im not sure on psu

[AceGamingProductions]

wow this is such a horrible how to video. this explains nothing that i dont already know.

[Quand9]

>.> fail

''The most important part of the computer is de PSU''

No it's NOT!

The most important computer part is the motherboard1

[JosephDThomay]

the most important part would probably be the most expensive part.

one of my graphics cards

[NOXXism]

Yes it is you should always put the psu first. It is the only component that protects the rest, so always try to buy quality psus

[ssganimal]

lol not posting any more coments about these weak vids.

[fr3akygr33k]

lol my specs

[TheDevilOnHoliday]

lol - mine's 250W...

need an upgrade

[tiagom135]

haha lol specs?

[TheDevilOnHoliday]

uhh...

Pentium 4 Northwood 2.66 Ghz

MSI-6577 Motherboard - 533MHz FSB

1.5 GB DDR-PC2700 RAM

ATI Radeon HD2600 pro 512MB (on a 4X AGP slot :D)

80GB Maxtor Hard Disk

250W PSU - probably melting away...slowly...

I upgraded the graphics from a GeForce 4 MX 440 and the RAM from 512Mb.

Yeah - my rig owns.

[tiagom135]

hahahahahaha ur the best!!!!!!

man oh man is this ridiculous. some power supplys age faster when not in there happy range (technical term), so it can be just as much of a problem to get a too big power supply as too little. sata requires a adapter and loses functionality when using a 4 pin. and get a 20 pin power supply if you have a 20 pin mobo. finally for most home users the power supply is the primary if not the only fan.

[GameSinewPCs]

Sata drives only lose the 3.3v line Staggered spinup and hotswapping capabilities by using a molex, all of which has no effect on most individuals installing an hdd when building a pc. Also, 20+4pin connectors are now standard in the market, are backwards compatible usually are to the atx 2.1 standard, offer more features and greater protection/reliability and usually all at the same price point.

[DonHoraldo]

"all of which has no effect on most individuals"

but the one who needs it...

"Also, 20+4pin connectors are now standard in the market"

and then you have a new branch of useless wires helping to clog air flow and increasing the risk of shorting.

[GameSinewPCs]

Individuals who need Hot swapping will usually know something about the sata standard. And even if they don't, they'll be using a sata HDD plug interface which will have power plugs to the specified sata, sas or scsi standard (not molex). Also, noone really needs the staggered spin-up, as that is more of a precautionary measure for users ill-equiped with an under powered unit (hence why the recommendation to get a higher wattage unit). Higher wattage units of the same quality will not age...

[GameSinewPCs]

faster than similar lower wattage models. Any difference in loss of power will be negligible. Equate this to the freezing of H20. It is a mis-understanding that freezing warm water is faster than freezing cold water when yes the change in temperature will initially be quicker, the change in temperature at any given point is the same making the overall freezing process longer for the warmer water.

[DonHoraldo]

"will not age faster than similar lower wattage models"

that is where you are wrong. there are parts of a psu that deal with the higher potential demand even when it is not used. some high end psu are built to compensate but the life span of a psu under used is shorter than one that is just right.

[GameSinewPCs]

The degradation of dielectric materials in the capacitors of PSUs age at fairly consistent rates relative to their material type rather than their rated capacitance. Not that there isn't an effect of differing load inputs versus their respective capabilities, but in general this is negligible to even the most concerned of users.

[GameSinewPCs]

Generally higher voltages help to retain the state of the dielectric materials, implying also that the unused capacitors of larger wattage PSUs would not be exposed to as much voltage regularly processed through them resulting in, negligibly, shorter life-spans.

Two 4-pin connectors will not impede airflow and at worst will only affect aesthetics. Though I usually disagree with these videos on a whole, they must be taken with a grain of salt and their intended consumer-base considered.

[DonHoraldo]

"Two 4-pin connectors will not impede airflow"

in a system like mine they would be shoved up in a spare cd drive. but that's part of my ventilation so your adding extra feet of wire to block airflow.

[GameSinewPCs]

The additional two 4-pin plugs, the 20+4 pin for mainboard power and the 4 pin 12v power cord, are required for almost every modern motherboard and cpu. Users who do not need these plugs are replacing a PSU from an older system ,usually beyond 6 years old. If the 20+4 pin 4 pin connector is not used, it is attached to the 20pin connector and will be identical to having a 20pin to begin with. And the additional 4pin cpu connector will not impede airflow in any tangible manner.

[DonHoraldo]

"And the additional 4pin cpu connector will not impede airflow in any tangible manner."

except the way I just stated.

[GameSinewPCs]

The MTBF should be a constant between any two PSUs of differing wattage outputs that you're considering and most quality PSUs of the ATX standard are rated for well over 100,000hours under high * centigrade testing conditions.

[GameSinewPCs]

So yes, a psu running at a power consumption level closer to its rating may potentially have a longer lifespan and less dielectric degradation however when compared to a similar psu of lower wattage it will still retain power capacitance above the lower psu's rating for a longer period of time than the lower rated PSU.

[GameSinewPCs]

Overall, any two psus of the same grade materials, despite different wattages, will maintain almost identical life-spans and any difference in degradation rates of the dielectric materials will be negligible or otherwise offset by the freezing analogy that I earlier alluded to.

76000 videos?!!!!!????

[orgthingy]

yes, people who own this channels are "partners" so, not only one did these videos

[F22Barrier]

Dum ass

[christoph2005]

I wouldn't say it's the most replaced part. It only is if you get someone like geeksquad to "fix" your computer. They'll fix you good alright. Usually when they say theres something wrong with the PSU, there isn't.

I have not yet had to replace my power supply, but I did build this computer back in 2005...

[4nt1pr0]

lol what power supply!!! somekind of 15bucks shit
