PSU's keep failing

[Cat With A Mustache]

My PSUs keep failing. I built my own computer, and I was using the integrated video chipset. I finally bought a video card, that said it needed a 550 watt PSU. so I bought one, exactly that much and put in in my computer. While waiting for my video card I had no problems. When my card arrived I plugged it in and had a good time. Whenever I played a game however, my computer would randomly turn off. To overheating I was guessing. However then my PSU turned off, and won't work. The mother board lights stay solid, but when I hit power, my boards Q-codes flash and nothing happens. I went out and bought a 575 watt PSU and the same thing happened. Randomly shut off and then never worked again. What can I do to stop this from breaking another PSU.

make and model of the PSUs you bought? Make and model of your processor and GPU as well as what other components you have connected. Where do you live, what are the ambient temperatures and how stable and reliable are your mains power supply?

The two PSU's are Logins. Not too sure on the models. My computer is running an AMD A-10 5800k 3.8 ghz Quad Core prossecer, a Crossblade Ranger motherboard, and a 6970 Radeon HD Dual fan GPU. As for things connected, all I have is a mouse, keyboard, ethernet cable, and the DVI input. Also I live in northwest washington. So itit never gets very hot here.

Never heard of that brand of PSU. DO you have a link to where you bought them or an online store that sells them? Might be that they are inferior.

Actually I bought both of these from a local computer store. They were like 43 dollars each so not very expensive.

Get yourself a reputable brand like a seasonic, Antec or EVGA.

Edit. I changed the list, initially I proposed a 500W PSU and then I realized you said you needed a minimum of 550W.

Also, interestingly, AMD has a list of recommended PSUs on their website: http://support.amd.com/en-us/recommended/power-supplies

-I am 100% sure that the reason you PSUs failed is that they dont have enough amps on 12v rail
