Hi, I was wondering if there is anyway to test my power supply. I believe it is not giving enough power to my video card, causing my computer to crash during gaming. By the way, I do not have another computer to help.

Power supply= Kentek 750Watt (I know it is a cheap quality, that is why I want to test it)
Cpu= Intel i7 2600k
Gpu= XFX Double D Radeon HD 7970 GHz Edition 3GB
Motherboard= Asus p8z68-v lx

Well, when I first built the computer, I didn't know about that. Now I'm lead to believe it is causing my computer to crash. If you'd like to know more about my problem, you could try looking at my other forum question.

The tester will test 6-pin PCI-e power cables, it's quite versatile. However, if the power supply is marginal or not up to powering your system, it may not prove much to plug in a PCI-e cable to a tester, it will probably work fine with little load on the PSU. The issue is more likely that under heavy gaming your system is drawing more than the poor-quality PSU can put out. A tester like I linked to will not be able to test that, you would need scopes or probes on different parts of the PSU during your gaming session, sort of what sites like Tom's does when testing PSUs under load. I don't think that's something you're interested in. Just buy a brand-name, good-quality PSU and stop risking your quality hardware, because worst case your PSU will actually fry your hardware.
