Hey all,

A few weeks back, I had a few extra dollars to upgrade my GPU. I knew my PSU wouldn't support much (300W), so I upgraded to a Sentey XPP525-PS (525W). It was a bargain buy, but had good reviews on Amazon.

I ordered the PSU and GPU at the same time, and received the PSU first. After installing the PSU, my hard drive fried. Prior to installing the power supply, the computer had no noticeable issues. After replacing the hard drive, the computer ran fine. I then installed the graphics card (Sapphire Radeon HD 7950 3GB). As soon as that was installed, the wireless card stopped working. So I replaced the wireless card with a USB wireless (shared internet with housemates).

Things were running great until yesterday. Mid-game, the computer shut off and wouldn't turn back on. Thinking that maybe the power supply just went out, I replaced it with the old one, and still nothing. Anyone I've talked to so far says it sounds like the motherboard was fried.

I'm not sure why this cascade of failures happened and would like to know what I need to do to avoid this again. I'm in college, so I don't have much money laying around. Replacing what has broken has already been outside of my budget, and I'd like to minimize any further spending. That's why I'm coming to you guys. If I made a critical, newbie error please be patient. I realize now that I shouldn't have assumed that I could do this on my own.

The computer is only 4 years old. Here's a link to the model specs:

Hi. The short answer is that you cheaped out on the PSU. That is the one place where you don't want to cheap out on. If one goes, it can take a component or more with it as you found out ( HDD ). Look at Corsair, XFX, Seasonic, PC Power & Cooling, or Silverstone to name a few reliable brands.

'Good reviews' from people who have zero clue.
It died, and probably took out the motherboard.
