Hi, I have a 9800GTX+ from BFG and am wondering whether or not a 400W Seasonic power supply would suffice. It has two +12v rails each at 17 amps to combine to a max total of 34 Amps. Also if it is compatible how would I go about installing it. I already have a Molex to 6 Pin power adapter, do I just connect it to any molex connector?
That PSU actually has 30Amps +12V. Look at the label. The Max Combined 12+ is 360watts (360watts divided by 12volts = 30Amps). The 9800GTX+ recommendation is 450Watts and 24Amps +12v. You're in good shape for your system running the 9800GTX+. Use the Molex to PCI-e adapter for the 2nd PCI-e power connector.
Thanks for the info also how about over clocking? Would I be able to do that or is it best that I stay at stock.
