Power supply fried PC?

[porterjonny53]

Since I got a new case and motherboard yesterday, I took out all parts in my pc, and built them in the new case with the new mobo. after trying to turn it on the psu didn't even turn on. I know the PSU is dead but how can I tell if any of my other parts are damaged??? I have no other PSU.

Without a working PSU I don't think you have any options. All you can do is buy or borrow another one and try it out.

Did you get a sound or anything or was it completely 100% dead? If it's the latter, are you 100% sure you've connected your power switch correctly? First step would be to re-seat your ATX cable (the really fat one that goes from PSU -> motherboard). And then triple check all your case -> motherboard wires (the little fiddly ones).

If it's still all dead you can't test anything without a working PSU unfortunately.

Here's a cheap ($40), acceptable quality unit which will power just about any single graphics card computer (unless you have high end or overclocked components): http://pcpartpicker.com/part/antec-power-supply-neoeco620c

I should add that you're probably okay. Most of the time you *should* get away with a dying PSU without it taking other components with it... but that's not guaranteed. If you were running a decent quality unit it will have had better protections built in which gives you a much better chance than if you were running a bargain-basement POS unit... but whatever you had there are no guarantees.

As I said... probably/hopefully you're okay... hopefully!

Thanks for the peace of mind. I thought for sure at least one of my parts would be fried. I ordered a new psu today, so I will get back to you on how it goes!

You have triple checked all the PSU, motherboard and case connectors (especially the PW (power) switch connector) haven't you?

One more thought, you haven't done something silly (which, if we're honest, we've all done) and bumped the hard power switch on the back of the PSU?

It's just a bit of a coincidence that it goes from working fine to completely 100% dead as the exact moment you move cases. It's super-easy to mess up all those fiddly case -> motherboard connectors and a mis-connected power switch will make your computer appear completely dead.

One other thought, it's also possible (unlikely, but worth checking) that the power switch on your new case is faulty. If your case has a reset switch try connecting that to the power switch connector on your motherboard and then see if pressing the reset SW on your case has any effect.

It would just be a real shame to get a new PSU to find that the problem was actually somewhere else entirely. Having said that, if you're running a cheap or old PSU, it's not a bad idea to update it anyway. So as long as your new model is decent quality, it's not wasted money. Use this list if you're not sure: http://www.tomshardware.com/forum/id-2547993/psu-tier-list.html

Good luck. And make sure you post back so others know how it works out.

Lets look at this again logically,shall we? The psu was working in the old pc or you would not have put it in the new one. Now it does not work.
What is more likely is it is not 'turning on'.
I would look at the front case connector diagram and check the switch connections on the mother board, it is very unlikely indeed your power supply stopped working in the time it takes to build a computer and even less likely if it is not running.
My guess is the on switch for the case is not connected to the correct pins.
Check the power on switch connector.

You beat me to it... but I'm 100% with you here!

Yeah well, you were 100% with me after you let the poster order a new power supply despite the likely explanation being as obvious as can be. Still, no harm done if its an amazon order,he can cancel it just by refusing delivery.
Dont take it badly but think about the evidence submitted by a poster as well as the question they ask.
Some people get snotty about just wanting the answer.
Most will be grateful for a solution that costs them Zero money.

I don't want to get this thread off track and get too defensive here, but that's not exactly fair.

If you look at my original post I had already recommended the OP makes 100% sure than all connectors are right, particularly the power switch, as the first troubleshooting step. All your post did was reiterate the steps I had already highlighted.

And I started my second reply - once again encouraging the OP to slow down and try other steps before resorting to a new unit - before your post. The reason I replied to your post was because it only appeared for me after I'd submitted my follow-up answer. It was partly a "you beat me to it" post, and partly to highlight to the OP that he has multiple posters independently giving the same advice... so she/he would be well served to listen to it!

Anyway, don't want to get the thread off-track. I think the advice above is solid.
