Replacing out of production PSU (FSP400-60PNU) that includes a -5V spec. Most off the shelf PSU's do not include this spec. Can I ignore this?

ATX refers to a set of specifications that are needed to conform to voltages etc. So if you old PSU is an ATX unit then any new ATX unit will work.

This is a maybe. It depends on whether you motherboard needs an ATX 2.2 spec PSU with it's -5 volt line or whether a newer ATX 2.9 spec PSU will work.

All you can do is try it. I'd recommend a Corsair 400CX (30 amp 12 volt rail):

as a direct replacement.
