The correct way of replacing a PSU?

davedudes · 14 Dec 2011 at 13:51

I don't know if it's confidence or what, but I would like to know what you guys think of about installing a new PSU, my currrent one (Corsair TX 650W) is buzzing when under load I know it's defo the PSU and nothing else. So i've bought a Antec TruePower Blue New Modular 750W '80 Plus Bronze' Power Supply for the replacement. I'm just a little confused regarding the right/correct steps in order to install.

Really lost my confidence in my ability, i've built a few pc's in my time. Just want to do it right that's all, hope you guys can help.

Cheers.

I think officially you should have an anti-static strap grounded off somewhere etc. But if you are just a normal person then:
turn off pc
unplug power
I normally press the power button a few times to try and dispense anything getting held
open it up
remover all cables from board / drives etc that are part of the PSU
unscrew psu from case
replace in reverse order.

I've built plenty of pc's in my time like i've said.

Never used an anti-static wrist strap, I always touch the chassis before I get anywhere inside the case, thing is it may sound idiotic but i know what to do but im apprehensive about doing it just in case something untoward happens, like I said I believe it's my confidence because I don't think I lack ability. I know many people have many ways of doing things, think if i plan on what to do then things will work out for the better.

Sorry to go on guys.

Just a quicky - touching the chassis will only work if the chassis itself is still earthed. If you've removed the power cord altogether theres no guarantee that it'll earth.

If you want to be very careful you can touch the chassis whilst the power cable is still plugged in and off at the wall

I personally don't worry about it too much either these days since I've never had anything die on me from static but I guess if it saves you the bother of returning something it might be worth it? lol

As for changing a PSU - tis just a case of removing the old and fitting the new really

Just remember to reconnect everything to disconnect lol

I doubt you even need to worry about grounding yourself unless you like to like to rub your hands all over the electrically conductive bits of your motherboard when removing pladtic connectors.

Swapping a PSU is pretty straightforward. It's the cable management that comes with it that takes the time in my experience.

The cable management was my main concern, bit of a ball-ache too.

trial and error + cable ties = good cable management

You can discharge your static by touching the bare metal part of a radiator with both hands, I do this at the start of a build and maybe halfway through, never had a static problem.

I know about static am not a complete noob, i'm just a wimp when it come's to the installation of the PSU.

I do this too.

I also use a wrist strap which I clip to the case and leave it plugged with the main socket switched off and the switch on the PSU off too. Never had a single issue yet *touch wood*.

Don't do it bro! you'll electrocute yourself and then your computer will blow up! only jk, you'll be fine, they trusted me and a bunch of 16 year old's to do it at our college, so if a bunch of immature fools can do it, so can you

Unplug all cables at the drive side, to prevent snapping delicate SATA headers on harddrives. Then unplug fans, motherboard.

While doing the above, feed each power cable to the PSU through the holes - eventually you'll be able to unscrew the PSU and the whole lot will come out in one go.

Personally I'd leave the PSU switched off both on the PSU and at the wall, but still plugged in so you're earthed.
