major PSU problem

Dark Lord · Oct 10, 2006, 05:41 AM

i just got my antec NE 550 this evening and ive got it all hooked up right now.

the system starts, posts, and seems to run fine. for 35 seconds or so i let it run.

when i checked voltages with mbm5, everything looked good except 1 very large problem. it said my -5.0 was running at + 3.5.

im going to double check all the wireing and double check the owners manual here, but i think ive got everything hooked up right.

any idea whats going on?

ok, i found the problem, now i have no idea how to fix it.

looking at the 20 pin connecter, it only has 19 pins in it. its completly missing the cable for the 20th slot.

now, looking at the picture on the DH review it looks like its also missing the same plug and the same location.

looking over my mobo owners manual, the spot thats missing the cable is the -5.0 lead.

looking in the bios, it says the -5 isnt supported. i also find no mention of it on antecs website.

I remotely rember that legacy hard ware (old) required the negitive rails as I had a PSU with a simular issue on 12V but everything ran fine....
