To clarify how much 12V amperage each PSU Ferrari listed has:
Cooler Master: 34A
As for which PSUs are of the highest quality, refer to this list
. I always recommend getting a PSU from Tier 1 or Tier 2.
That Antec Veris won't use much power... After all, it doesn't have a processing unit on it or any moving parts. Similar front panels for sound cards use about 5W. A hard drive will only use about 12W. Your current PSU would probably be able to handle both.
However, getting rid of a generic PSU is always a good idea. The first PSU Ferrari suggested would be fine. A 400W Corsair is much more powerful than a generic 350W PSU; at least, it's much more powerful then you'd be led to believe by looking at the wattage alone. It will also provide more stable power, lengthening the life of your system, and be more efficient, saving you on your energy bill. And, at $30 after mail-in rebate, it's a great deal.
If you really want more juice, that 500W OCZ @ $40 after mail-in rebate is another good deal, though again, you really don't need that much power for your system.
