I was given a system that I think has a bad power supply, but the rest of hardware seems okay. I don't remember the name/model of the video card (I can post that when I get home), but the mobo docs say it wants at least a 600 watt PSU. I'm reasonably certain the problem lies in the PSU based on what I was told about its history, i.e. It worked fine for a long time, then random crashes, BSOD's, and then it would run less and less time before shutting down.
Power the machine up and the drives and fans spin up, it passes post, and tries to boot from a Ubuntu USB stick. Hit delete a few times to get into BIOS Setup and -- it shuts off. Hitting the power button again will start it up again but it'll turn off quicker. There is no OS on the hard disk yet, so diagnostic software won't help at this point.
CPU: Intel Core 2 Quad @ 2.5GHz
RAM: 4 Gb DDR2
VIDEO: ZOTAC ZT-95TEK2M-FSL GeForce 9500 GT
MOBO: XFX nForce 750i SLI
PSU: 600 Watts
2 DVD+RW Drives
1 160 Gb SATA 2 HD (For testing. Bigger HD's to come later.)
Going to do a voltage test to make sure, but I guess one question is this: What's a good make & model PSU for a box like this? Any particular brands I should stay away from?
This is an older but still useful machine that I'd like to get working, but would like to avoid spending money on a lost cause. A PSU is a fairly reasonable fix at this point.
