I found the bit-tech and legitreviews reviews sorely lacking. I wouldn't even really call the legitreviews item a review...it's more like an announcement. They were more like "it's pretty, and well packaged, and it ran for awhile".

Neither appeared to address the PSUs handling of input AC variations, or DC output ripple or spikes due to load variation. It looks like all they did was measure DC averaged values. Didn't see any mention of testing at environmental extremes. No mention of hold time evaluation either.

The president of PC Power & Cooling by the way, is the only PSU company executive that I've ever heard/read say that all PSU parameters should be tested and reviewed while operating under the extreme conditions of AC power, DC loads, failure conditions (e.g. overloads/short circuits) , temperature, and humidity. He has confidence in his products.

This is from Nvidia. I to will be run ing a 8800 GTX KO due to be here tomorrow. 630 core 2000 memory stock its rated by Nvidia right on the box. Required 650 watt 32 amp on 12+ rail Required. It don't even say recommended lol It says Required. The interesting part is the EVGA required PSU for 8800 Ultra is 650 watt 34 amp 12+. So keep in mind any overclocking and more amps will be needed. Think it stands to reason that 39 amps on 12+ is a must. So yall know the 8800 GTX KO says 457 watts power usage under full load. really cool how EVGA when ordered from there web site print this on there boxes now.

The PCB design for the GeForce 8800GTX is similar to that of the numerous leaked photographs that have turned up over time. However, unlike some previous pictures, water cooling is not mandatory for the G80. Both the GeForce 8800GTX and 8800GTS manage to put out quite a bit of heat, but fortunately the dual-slot cooler should be suffice for running at stock speeds. The pictures are, however, correct in noting that dual PCI Express 6-pin connectors are needed for power on the GTX variant. For those users immediately upgrading to the GeForce 8 series you certainly will not want to skimp on the power supply. For a single GeForce 8800GTX the minimum power supply recommendation is 450W for a standard desktop setup, though we always recommend getting a much higher power supply. The GeForce 8800GTX and 8800GTS also are HDCP compliant, support dual-link DVI, VIVO, and HDTV outputs.

Product: EVGA 768MB e-GeForce 8800 GTX KO ACS3 626/2000MHz
Website: http://WWW.EVGA.DE
System Requirements: Minimum of a 450 Watt power supply. (Minimum recommended power supply with +12 Volt current rating of 28 Amp Amps.) PCIe capable motherboard.

I have tested my machine with a Wattage monitor and it only takes 360w full load playing games with high res graphics. Anybody who wants to use there existing supply will be able to use a 500W so long as it gives the amperage.
