Need a better PS, right?

With winter now upon us, I've been sticking my radiator out the window with great overclocking success (Don't worry, condensation and freezing is under control, I have plenty of glycol and silicone at hand).

It's dawned on me that my PS probably isn't cutting it. You guys be the judges - is this what happens when a power supply is maxed out on a single rail?

Never ever, ever use software to determine the voltages from your PSU.

Use a multimeter if you have one.

Good advice. I monitored the 12V CPU rail with a multimeter. Here are the results:

SWVolt = CPU core voltage reported by software utilities.
HWVolt = The reading I made on my multimeter.
% = CPU utilization percentage
temp = CPU temp.

SWVolt---HWVolt---%---temp
--1.47----12.13-----2----16
--1.43----12.12-----5----18
--1.36----11.88----100---34
--1.38----11.90----100---34

These aren't exactly synchronized in time. The measurement was limited to my ability to look at all these things at once. However, the evidence seems to be there that the PSU is being taxed to the max.

The next step to confirm all this is to read a full 18 Amperes out of the rail. The fuse in my multimeter is only 10A.. alas...

Look very good to me. Looks like you won't need a new PSU.
