I have a question about power supplies.
First off, let me say that I am trying to achieve a relatively stable overclock that will withstand continuous hardcore gaming
for many hours, and still enable "cool and quiet" with the C6 state on to conserve power when doing less power hungry things.
My test rig is below.
Here is a screenshot of the voltages across the PSU during 3DMark 11 benchmarking, with the CPU and GPU under full load,
overvolted and overclocked (4.84GHz):
This was done with the Corsair CX600:
Notice that the 12V rail idles at 11.58, and sags to 11.28 during the run. Also the 5V rail, while stable is at about 4.9, and the 3.3 at 3.18
I was suprised that a good reputation PS would be giving me these numbers.
I'm actually able to push the thing to a working 4.97Ghz OC, but this is not stable enough for continued use under load.
Also note, this is a budget build and the PSU was 69.99 - 20.00 rebate.
Any thoughts or recommendations?
ohh..Also note how quickly the temp drops off on the CPU after the benchmark.
This is with a Silverstone Tundra TD03 for about 100.00 Very happy with this unit.Edited by ArconHadron - 2/26/14 at 8:46pm
