Best method to "Benchmark" a PSU?

post #1 of 8
Thread Starter 
I have three new PSUs to play with before I pas them along and I was wondering if any of our PSU gurus (like Chozart for example) might know of the best way to test and compare performance of PSUs.

I have an Xclio 500 Watt Modular (the bottom tier of that X14 line)

a ThermalTake Toughpower 700 Watt Modular (which has gotten good reviews)

and a PC Power and Cooling Quad Silencer 750 Watt PSU

Is there any sort of SW that is good for standardized monitoring and testing?

What sort of "benchmarks" or other stress tests would generate a strong load for the PSU to handle?

I am curious about this as I have never owned and XClio or ThermalTake PSU and want to see how they compare to a top tier PSU like the Quad Silencer...

Thanks in advance.

I'm thinking the most you could do is test rail stability. Test it at idle...just as you would CPU, but load should be something involving graphics to get that GPU pumping aswell...maybe orthos while 3d06'ing? Test the rails throughout that...notice droops and such. Thats how I would go about it. Either that, or take a look at what they did at JohnnyGuru or whatever, everyone loves that guy for PSU reviews.

you take one of the molex connectors, and stick the multimeter into it to get the voltage, then monitor it as you put load on the PSU.

Well, if you didn't know, here's a link to a site that shows where the 3v, 5v, and 12v areas on a SATA power connector are. Need a rather small multimeter end though.

You could also ask about this kind of stuff on the Jonny Guru forums. You will get much better help over there.

Best and only way to bench a PSU is to test how voltage fluctuates from idle to load.
