I just installed an Antec 550 TP 2.0 and my ABIT EQ alarm went off... upon checking, my -5v was reading as 3.5v. I have read that on Athlon systems, the minus voltage readings do not really do anything, but I want to find out what is happening here. Is this a defective PSU or just a change in the way power works on newer motherboards?

The motherboard I am using is an old ABIT NF7-S 2.0, the 2nd computer listed in black letters in my sig.

New PSU, old system, but why is the -5v reading as 3.5v?

I don't think the -5v rail is used much anymore these days. It's a relic from the past that hasn't hit the chopping block yet.

You should be fine.

I have an Antec Aria case, that comes with it's own specially shaped power supply, which I use as an HTPC. According to my Biostar M7NCG 400 motherboard, the -5v rail is producing at least 64v the last time I checked. I have had no problems in the last 2+ years.

Don't worry about it. If anything, mine will blow up first and I will let you know about.

That's assuming I'm not dead.
