PC problem with PSU?!

[thestbar]

So a friend of mine has a PC which is 7-8 years old.
CPU: AMD Phenom II x6 1075T @stock
GPU: Sapphire Nitro AMD R7 360 @stock
Mobo: ASUS M4A87TD/USB3
RAM: 2 x Kingston DDR3 2GB
Optical: Sony DVD RW
HDD: 1TB Hitachi
And his PSU was Force 600 Watt. A really low end PSU. Yesterday, his PSU died (it almost burned - stuff like smokes and a lightning). So he was desperate because he is on a project and today he went on a store to buy a new PSU. I told him to buy Corsair VS 550 W 80 plus ( his budget was limited on 50 Euro). I am pretty sure that this PSU can handle his system, I checked it on Coolermaster's page where you can calculate the PC wattage and used settings such as 3 HDDs and 1 SSD 16 GB RAM and little OC's and and recommended Wattage was below 500 W. When talking about reality it asked on full load 350 Watt! Anyway, PC with the new PSU still faces some restarts. Any ideas? We have checked many things. Is it really possible that analog 5.1 headset short-circuits the system?

Cheap PSUs can damage other components when they die in the style you described.

A 550w quality PSU should be able to run those components with no issue. Although the particular Corsair PSU he picked is an entry-level unit, it still should be an upgrade over a PSU that ended it's life with "smoke and lightning".

He really needs to determine if any other components were damaged. That involves removing all non-essential components/swapping known work components, which is a time-consuming process.

Of course we tested everything and -thanks god- this PSU didn't kill any other part. We also tested the PSU on full load and everything works great. The real problem was that he had the stock cooler on this Phenom and things were going really hot under pressure so I underclocked his CPU, untill he gets a Coolermaster Hyper 212 Evo, so we can go back @stock clocks or maybe oc it a bit.
The odd stuff is that the overheating problems (freezes, no reason restarts, bsod etc.) started after the death of the PSU. Anyway, I think we fixed it.
