Been having some random computer shut downs when under full load in games which makes gaming a little hard. Seeing as how I've tried all the software solutions I could think of (drivers, windows update, game update, even a fresh install of Windows 7), I'm looking at hardware. My first culprit is my now aging, under powered PSU. The system I'm running is a Core 2 Duo 2.8ghz (want to go Core 2 Quad soon for what that's worth), Radeon 6790, also have a Radeon 4850 for my 3rd and 4th display (had it lying around, cheaper than ordering two active Displayport adapters and no it's not this, had the issue before I installed this card), a 128gb SSD, 5 SATA hard drives (ranging in size from 400gb to 1.5tb), X-FI sound card, and 6gb RAM. All this is running off of an aging 470 watt PC Power & Cooling unit. I'm trying to keep a budget of about $65, which I know won't get me a top of the line PSU, but also keep me out of the bargin basement units. I've got these two picked so far http://www.newegg.com/Product/Produc...82E16817182200 http://www.newegg.com/Product/Produc...82E16817182278 but am really looking for some input or suggestions as it's been a little too long since I've been as into PC Hardware as I used to be. Any help is appreciated, thanks!!
