these are a nice idea but i read online in some places saying that the power supply has to be under load to really know if its bad or not... they saying that yea a power supply can pass when not under load (using these testers) but when under load the psu can be bad which these testers wont tell you... i was thinking of buying one just wanna know the truth here

I used to use one for work, it was great when you were nearly 100% sure it was the power supply.

It was able to test the current running through the different rails, this meant let's say the 5v rail was only giving 1v it was pretty much dead. Just made those things easier to test and make sure you were right. I like them for work but wouldn't use them otherwise.

Off topic: You know your computer specs can be put into our system and have it display even better.

This. Although, they are really handy if you are doing single sleeving jobs and want to confirm your wiring thumb.gif
