What is an "IDE" connector?

[kingkoopa187]

the magnetic screwdriver is not powerful enough to do squat imo

[husla14]

video forgot to state the number one rule. Being were dealing with PSU... like my instructor always said "NEVER OPEN THE SILVER BOX"...thank me later 120 volt alternating current will stop your heart DEAD....

[husla14]

A+ tech here... never had a problem using magnetic screw drivers on chassis...or PSU... I actually preferer magnetic screw drivers makes installing and replacing components a BREEZE. Jus sad to see other TECHNICIANS arguing about magnetic screw driver LMAO..foolishness

[SimeonDove]

Good video for practical work

[perplexer100]

nice tutorial very helpfully THNX ;-)

[creedstruth]

Helps to have a magnetic screw driver if your going to be doing any PC repairs and etc. :)

[nightsdeepbreath04]

@creedstruth : Like a Sonic Screwdriver! :D

[popomartin2]

@creedstruth Is this a joke? Magnet+Computer=Disaster... Just don't bring noobs on stupid idea's...

[creedstruth]

@popomartin2 Your a dumb ass in the process of putting together a machine a magnetic screw driver will do nothing.... Your a tool... I've been building these fucking things for 10 years.... And have used magnets or a magnet screw driver each and everytime.. So either im the luckiest fuck alive and im not or you sir are full of shit...

[popomartin2]

@creedstruth You should know magnetics can damage you're PC. There you have it. So why the fuck am i full of shit?Why all the abusive words? (And pls don't tell me you assambled pc's for over 10 years. Otherwise grow up, you sound like a14 yo.

[SPARTAN112CE]

@popomartin2 not quite true, yes you cant use magnetic screw drivers around hard drives, but anywhere else on the system is fine, ive been working on and building computers for nearly 4 years now, and i use a magnetic screw driver, but i have other tools as well for each situation

[sandpir8]

@SPARTAN112CE About the only way you'd damage an HD with a magnetic screw driver is if you use one to take the HD apart... heh... Inside HDs are some of the strongest magnets you'll find. The magnetic flux of a typical magnetized screwdriver is almost negligible in comparison.

[sandpir8]

@popomartin2 Please explain what disaster you're talking about... Are you afraid one will erase yer floppy?

[kentokae]

@sandpir8 Magnets can deal allot more harm then erase a floppy. If you have any knowledge of Electronics you'll know that the power Supply have magnets inside of it.

The wires connected to the motherboard is not connected to the wires leading from the power socket on your wall. The power from the wall outlet is transferred wirelessly to the wires that connects to the motherboard via electromagnetism.

[kentokae]

@creedstruth Not to insult you as the others, but they are correct. Using a magnetic screw driver on any electronic equipment, especially power supplies is a recipe for disaster, and It is a bad practice. The Reason you have not experienced disaster is because most newer electronics have the protection against magnetism. Power Supplies on the other hand might pick up the magnetism as a power input and attempt to send that power to the motherboard.

I hope you understood,and not take offense.

[creedstruth]

@kentokae Ive been doing computer repairs for 15 years ive used a magnetic screwdriver many times and never had a issue ... I suppose if you turn it on and sit it on the powersupply you may have a issue however mounting in on a top power supply rack , putting the screws in you will have no isuse... Like with guns if your not a retard you have no issue .... same with this... Again you dont turn the PSU on while your screwing it in....

[kentokae]

@creedstruth Study Electronics and Electrical engineering the Power supply dose not have to be turned on OR Plugged into the wall there is a component in a power supply called a Capacitor that maintains it's Electrical charge and another component called a transistor (or is it Transformer)that basically uses a magnetic field to transfer electricity. If you use a Magnetic screw you could initiate electric transfer. and short out the PSU, motherboard or fry yourself.

[creedstruth]

@kentokae Your not going to short out any PSU over 500 watts if it was possible it would of happened to me by now... I used to work in a computer store building them sometimes we'd build 10-15 a day... and ship them out , also did repairs.... FYI , without it being on enough power isn't going to be transmitted to shorten most powersupplys...

[kentokae]

@creedstruth you worked on computer you need to study electric engineering kid. Every Electrician will tell you that using magnets is a risky business, because of how Magnetism and Electricity are so closely related and how they interact with one another. You can make a Wireless Power cord with Magnets so you are just deteriorating the Power Supply, which is BTW usually the first component in the PC to die.

[creedstruth]

@kentokae Depends on the power of the magnet , and the power of the power supply... The power supply is the first component to die because it is the most used....

[kingkoopa187]

@kentokae who is playing with capacitors which like you said holds the charge? no one smart enough to do pc repairs unless unplugged for an extended period a magnetic screwdriver is not strong enough to do any damage plus the hard drive itself has stronger magnets which is what? usually 1 inch from everything else that your worried about? gg newb. static discharge can f$ck things like ram as well as something on the board grounding out. Cardboard box it and man up.

[Dellster13]

very good video...ashame the Frame rate isn't that good...but still AWESOME tutorial...

[MrWTFisthisshit]

Have the same pc :D its HP

[chuasmare22]

thank you so much.

[userz1y2x3]

this is an awesome training video. the video is super clear with perfect camera angles. the guy in the video is professional looking and is very articulate. credit is due. good job on this vid guys. PROS.
