It's a decent quality one, but not very exceptional and not even the
biggest in the range. It's an Enermax EG365:

Enermax do provide more current on the +12V line than many PSUs, but
you'd be hard pressed to find one that'll provide less than 10A, most
providing 15A+. The 350W no-name PSU in my other PC provides 16A.

A recent P4 burns the best part of 100W and gets that from the 12V
line (via a regulator of course) - that's 8A before you've even
installed a drive, and they are another 1-3A (spin-up) each.

No, I can't argue with that :)
