Hi, my my - top one in my sigs only consumes, with the lcd connected to the power plug as well, ~ 130W, even under load. Seeing as the graphics card and motherboard said I need at least a 400W psu, i was surprised when I measured this. I checked the watt meter on the kettle and hover and was getting the right reading. My PSU is 600W, and i wouldn't expect it to be using 600W, yet I would expect it to be atleast a couple of hundred watts. The PSU was a fairly cheap one as well, so there are inefficiencies in that. Then I tried it on another pc (think it's near bottom in sig) celeron d 2.53ghz, 2 gb ddr ram1 ide disk 250W PSU ati raedon 9550 and that was about ~ 130 watts aswell. I know ddr ram and most ide drives consume more power than there successors, but still 130W power consumption is surprising.
