thanx btw whats your power usage on R9 290?
one more thing I pmed you .. pls check it
It's very high. Don't have wattmeter, so can't say how much from the wall, but gpu-z says 210W per gpu.one more thing I pmed you .. pls check it
for those who don't have watt-meter plugs.
do it the old fashion/cheaper way
buy a good 20-30$ clamp ammeter with voltmeter (all in one), a custom made extension cord (where you can split the wires so you can easily clamp the ammeter would be handy).
measure the amps and measure the voltage.
formula:
amps X volts = watts
For the same price you can almost obtain a wattmeter, even though it's not very precise it can do the job in an easier way
from where i live, those wattmeters are not available...maybe some people here already have one and they just have to use it but didn't think about it yet ... in my case i just figured it out since i already have those tools in hand.
Just use GPUz for core wattage and add 40W for PCB and the PSU conversion factor.
