Ultra X3 800w Power Supply Review
 

If you�ve noticed lately, everything is more power hungry than ever. A decent video card now requires its own power source, and many people are Crossfiring the crap out of their systems, so that�s twice the original juice flowing through. And now there are Blu-Ray drives, and you'll probably want to keep your old DVD burner for a while, so now you have two optical drives. Twice the power again. Overclock, put in more RAM, a million fans, and all the gadgets that plug into your USB and suck away more energy. Jeeze, people. I hope you are all enjoying that hefty electric bill.

let us not exaggerate shall we. Adding a few leds and fans to your system will increase power usage by a few watts, 10-30W at the most;

the difference in price between a 300W system and 330W system is not as big as you'd think...
