A single 4870 video card uses about 155 watts and 13 amps at full load. The rest of an overclocked high end system will probably use another 350 watts during a gaming session. The source of the information is a recent article about actual video card power requirements published here at Tom's Hardware.
The Corsair TX650 is more than capable of supplying power to your system. It has a single large rail rated at 52 amps.
Thanks, I thought so. I'm also going to use a Zalman 9900LED cpu cooler, and will be using an Antec Nine Hundred mid tower case which has three additional fans, which I forgot to mention. I should still be okay, right?
Thanks, just ordered everything except cpu cooler and case and pretty excited. Coming is:
core i7 2.66
corsair 650w psu
3x2gb ocz gold 1600 ddr3
HIS HD 4670 512mb video card w/ 2dvi outs - may upgrade to 4870 soon
sanyo 1TB 7200rpm hard drive
two sanyo 23" wide monitors
Vista Home Premium 64 bit
I have an old LG dvd burne I'm going to use initially, to add a blue ray burner soon.
I'm looking at an Antec Nine Hundred mid tower case.
For cooling I'm either going with a Zalman 9800LED air or CoolIt Domino liquid system.
I'd be interested in any comments or suggestions. Still think the Corsair is a good choice?
