ahh I see, so i guess i'll go easy on my AXP that ive been bashing for VR cooling then !!!
I've just been looking over my power usage readings I made with my new powermeter...
These are total system watts at the socket.
CPU idle/ GPU idle (2d mode) = ~125w
CPU idle/ GPU idle (3d low mode)= ~136w
CPU idle/ GPU idle (3d perf mode) = ~186w
Power limiter on
CPU idle/ GPU load (3d perf mode) = ~340-380w (loaded with OCCT gpu)
Power limiter off
CPU idle / GPU load (3d perf mode) = ~480-525w (loaded with OCCT gpu)
I'm assuming the CPU was still idleing in the GPU stress test, or using little power if not. (note CPU load / Gpu idle (2d mode) uses ~ 280-300w)
So this means that in OCCT with limiter on
, the card alone was pulling approx 215-265w
In OCCT with limiter off
, the card alone was pulling approx 355-400w
Insane !! Hope I didn't destroy anything else !!!
I'll find out 2mrw when my 580 arrives...... wonder how much juice that will use........ only joking
