I just received the above power supply from the Maplins and upon testing On a POWER SUPPLY TESTER, a -5V light is not switching on! I had 2 like this before and showed the same results like this and returned them.This is a third one! The -5V light on a tester does not switch on.Could this be faulty too? I am not sure!
I have not installed this and one of the last on the computer because I do not want any hassle of removing them.
Please let me know if I am doing anything wrong. 3 power supplies can not be wrong.
The tester is not faulty because a generic power supply shows all lights!
