The correct way of replacing a PSU?

[davedudes]

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 do have a tendency of worrying too much, ill suck it up and just do it, cheers for the reply.

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.

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