Introduction

For the past year I have noticed a trend towards smaller, more efficient power supplies. For a long time I wouldn't consider using a PSU smaller than 650-700 watts on my basic rigs, and that was when using midrange video cards. Currently, I have no problem using 80Plus 550 watters in similar situations.

The 80Plus icons found on many power supply boxes and ads actually means a lot. If you didn't know, a more efficient power supply will perform as well or better than a larger, less efficient power supply. Without going into the math and being rather general just to make a point, an 80Plus efficiency 500 watt power supply can do about what a 70-72 percent efficient 600-700 Watt PSU will do. We're talking about less energy consumption, cooler running, and often less money.

But forget about using power supplies with triple-digit wattage when building high-end multiple graphics cards rigs. Looking at nVidia's certified products list, there is only one power supply certified for a pair of GTX 280s under 1kW. And that's just a pair of VGAs, what about three? And what would you use with 4-6 GPUs on a CrossFireX system? And if you are independently wealthy, how about a Tesla Supercomputer?

So in this day of smaller PSUs, the 1kW+ power supply is still a legitimate choice for many enthusiasts and gamers. Today I will be looking at BFG Tech's latest and largest power supply, the EX Series 1200 watt modular PSU. Yeah, I know, BFG is a video card and motherboard manufacturer, but they have been building power supplies for some time. The EX 1200 has BFG's Frequency Conversion technology, which allows for 80Plus efficiency, even at loads as small as 10% (most power supplies aren't very efficient at very low loads). This technology makes the EX significantly different from nearly every power supply on the market. Read on to find out about the BFG EX-1200!
