Considering buying another HDD but I'm wondering if my PSU will be able to supply enough juice to handle all this. Here are some specs:
Enermax 460W (unsure of model #)
+3.3V: 35A
+5V: 35A
+12V: 33A
-5V: 1A
-12V: 1A
+5 Sb: 2.2A
+3.3V & 5V: 200W
Here is would I would be running if I connected all my HDDs (including the new I'd like to buy), etc:
- 2 IDE DVD burners
- 2 IDE HDDs (200 + 250)
- 3 HDDs connected via a PCI controller card: IDE HDDs (200 + 250) connected + 1 SATA HDD
- FX5200 vid card
- 4 sticks of RAM (512 x 4)
- 3 x 120mm LED case fan
- 2 x 90mm case fan
- P4 2.8GHz CPU + fan (fan runs off 4-pin molex)
- AOpen AX45-4D Max mobo
It's the 5 HDDs that has me a bit concerned. I think I've got enough amps to power up and run this config but I'm not really sure. Even if I can, I don't want to overload the PSU at startup while it tries to spin up those 5 HDDs - even if it can take it, don't want to shorten its lifespan. So basically, I want to be at least fairly certain that I'm staying within spec.
I've looked at the latest consumer PSUs and they would offer little gain in wattage and even lower amperage on the +12V rail (bad) so I don't think that's an option (besides, the 550W+ PSUs run for $150 on up).
So, what do you think? Have I got enough juice here? :)

If I go by that calculator, I would be up to 407W minimum PSU requirement.
