8800GTX power supply?

[BarryB]

I've got a PC Power & Cooling 750w PSU, capable of supporting two GTX's in SLi!

It has a SINGLE 12v rail that supplies 60A, not a split rail that divides the amps across the rails, so with my PSU all the amps are available to the system, no amps are trapped on rails that don't use all the amps!!

Getting a SINGLE rail PSU is the way to go, at least for me!

Your power supply will work if you don't put too much in the computer or the single rail can be overloaded and you can get crashes especially when overclocking everything. recommended sli boards have more than one rail. If the cards have their own supply rail nothing else will interfere with them.
It also states that the cards should be on their own rail. Not shared.
The amps rating is as important as the Watts.

After my faulty Thermaltake 1000w power supply. I am now looking at the PCPower 750 quad. It does make sense to have all the power on one rail. It is a good price and gets good reviews. I see the multirail models in this category only have 18amps on each rail. Probably not enough in some cases when working the computer hard. The 1000w models also seem to be larger. I had to remove my top fan to get the Thermaltake in. It lasted five minutes and stopped working.
