Power Supply Roundup: 6600GT SLI Stress Test
 

Power supplies are often an overlooked component when building a new system, and that can be a great mistake. Many just buy a cheap case, and whatever supply that comes with it is good enough. Then when they start overclocking, and adding components they will blame the CPU, or another component for the failure. I've seen it time and time again, and I always ask what power supply and memory they are using. Typically when there is a system stability problem and they answer some generic supply or stick of memory then they just revealed the issue.

Now in normal system building you should have a solid power supply, but we all know that right? Today we look into what happens when you take an SLI system with two power hungry video cards and max out the amps running through it. Why? Well as gamers we want to know what it takes to run an SLI system power wise so much so that we measured the peak amperage during gaming use, and found that cranking the settings up on Doom III at 1600X1200 just about does it. Yes, our SLI setup with the Asus A8N-SLI Deluxe, an Athlon 64 3800+, and two eVGA GeForce 6600GTs pushes a peak of 3.6 amps not counting a monitor. Considering that we generally account for between 3-4 amps of power total for each computer at our lan parties that number got our attention quick.
