Hello, I am in the process of building my new PC, and have a question about the PSU.

I have a Power Sypply Tester, its a cheap model that I gat from newegg; http://www.newegg.com/Product/Product.aspx?Item=N82E16899261013

I used it on my new Abs Tagan 800W PSU, all the lights are green accept for the one of the -5 indicator, and the "Intelligent LED" was also red. I decided to to try another PSU from my current PC and It did the same thing, here is the pic

Just incase the pic is unclear, here is the indicators: +5VSB +5V +12V -5V -12V +3.3

A. On the Power Supply tester is sas "If any 5 LED DO NOT light up, some of the basic functions of the tested psu have faild
B. If the "Inteligent LED" becomes RED. I means the tested psu may damage your device!!!

I mean I tesed it on 2 PSU, can it be that both PSU are corrupted or is the "power supply teser" is wrong?

Thanks
 
Modern PSUs don't have a -5V rail. Older PSUs used to have them.
 
I was thrown off by this, too. The 5V- just isn't required any longer. I use a little Ultra PSU tester.
