Power Supply Tester Tags: Power Supplies Light Components Last response: March 25, 2009 9:55 PM in Components Share alexbruce March 25, 2009 8:29:19 PM Hi Guys, Really quick question... Bought a PSU tester to check some older PSU's and have a question. I tested it on my OCZ EliteXStream and my cheaper winpower 600w one... and when i plug the 20/24 pin connector in all the lights show except the -5v It has +3.3v,-12,PG,+5VSB,+12,-5V,+5V On both PSU's everything lights up as normal except the -5v... When I plug it into a much older 350w eagle PSU, the only difference is that it doens't have a 6pin PCIE and HAS a P4 Connector, and ALL the lights come on including -5v. Should I be worried? or is this normal not to have a -5v on new PSU's? Alex.
