Thats awesome A-Grey, what card is the GTX285 replacing? I didn't know much about the FSP Booster until just checking it out, the performance of that PSU is very impressive for its size! I assume your going to use it for the GTX285 (or for something else)? Earlier today before going to class I setup the "Kill A Watt" meter to measure how many watts my PSU was pulling from the outlet. I didn't have much time to play around but I ran Prime95 25.11 Small FFT's along with 3DMark Vantage's "Jane Nash" benchmark which is the most power hungry of the Vantage benchmarks. Below is a photo of my setup (to give you guys an idea of what my system is composed of) and a photo of the meter while those benchmarks were running. The wattage peaked at about 491watts (but becaues of the camera delay it captured a lower number), lol! By the way my system was only running at 3600Mhz (400Mhz x 9.0x @ 1.25v and GTX295 @ 650/1418/2200 on stock volts). I'm still trying to get my setup stable at 4050Mhz (I can boot at 4050Mhz but as soon as I run Prime95 my system BSOD's). As soon as I get things stable I'll post the overclocked power consumption.
