Well I posted about a month ago that I had got a ATI 6870 and it didn't work. I thought it was either my PSU or my Motherboard and I believe after seeing most people being able to use the 6xxx on my motherboard that it must be my PSU (i've tried all drivers, different PCI-E slots, and the old jibber that most people will). Found my PSU sparking whenever I turned off directly from my switch and I can see some slight melting (not a good sign) inside the xstream powersupply. I got around $150 AUS to spend and I'm looking at Corsair and Cougar because of their reasonable prices. I need a PSU that can power a 6870 EFFECTIVELY with all the double PCI-E splitters that come with it and also if I want future crossfire the 6870 I want effecient powersupply for that. In my price range are currently the Corsair TX750 750W which is known as like the best PSU brand around and most stable. It looks like an excellent buy, even without modular (which doesnt concern me that much, just want the bloody card to run.) And then I'm also looking at the Cougar CMX 700 which was released a little while ago and hasn't recieved much spotlight. I cant find many reviews or discussion on the Cougar CMX 700 but the brand doesn't have a 100% perfection background like Corsair, but the chips of information on this series seems to be good. Other then it being modular and looking damn good, it seems to be fairly stable and reasonable for it price ($20 cheaper then the Corsair 750w). So which one or is there another in my price range? I use umart.com.au/ btw.
