I bought a corsair power supply over Ebay not new but a year or so old with part of a warranty. payed a good price 70$ and 10$ shipping, got it today and noticed that on the 24 pin motherboard connection the fifth pin on the left side is missing. I am a newbie to this sort of thing and this is my first computer build starting to get all the parts however is the pin suppose to be missing, if not is this going to be problematic or should it be OK .

Oh good I thought so its just you don't often see the 24 pin connector and was worried for a min thanks for your help. so for future understanding is that all power supply are missing the 5th or so pin or is that something specific to corsair.

A -5v line was there, it's no longer part of the ATX spec.

If a PSU still has that line, it's a good sign that it is an obsolete design, and probably a piece of junk.
