Hey guys, I was planning on picking up a 7870 or a 7950 soon, but my PSU is making me nervous. I have a HP computer, with 600w power supply. I know this is more than enough watts for the cards, but I'm not sure about voltages/efficiency or anything like that. (I know nothing about power supplies). The power supply is made by Delta, and is apparently high efficiency according to what it says on it. (I'm guessing that doesn't mean much). Any ideas on if this will be able to handle the 7870/7950 without any problems? thanks for any help! Here are some info I found on the unit 12Va --- 16A 12Vb ---18A 12Vc ---12A 12vd---10A 5.08v----16A 3.3v ----15A 5.08Vsb ----2A -12V ---.3A I know this isn't the best PSU, but I can't replace it, as that would void the warranty. Would it in any way potentially damage the card?
