How much power do I really need?

[YoYoBabyYo]

Right now I have a 350W Antec True Blue (yes, I know), but I am about to add a lot more components in. My question is how much power/amp to run a P4 2.8 HT, 2 SATA HDD in RAID 1, 3 HDD with one running the OS, an AGP PNY GeForce 6600GT video card? I do not play games and nothing is overclocked.

Here are the specs of my current PSU.

power supply calculator for intel cpu's

use that to calculate your wattage needs and then just make sure you have a +12v of 20a or more and you should be great

What is your budget? And I have a question, if you don't mind. And it is absolutely not with the intention to flame or anything. But is it a budget issue? Because in all honesty, I have two PSUs just in case. I might not even need two, but the power is there if I upgrade and put more stuff in. So why go with the minimum. I used to have power issues with Enermax 460w PSUs (not their fault at all--they were excellent PSUs, I was just overusing them like hell), so I went dual, and then got a UPS to clean the power going to them. Never had issues after that.

The 350w should be enough.

My budget would be around $50, but this isn't really a budget issue. Or perhaps it is. I just had my Radeon 9800 pro fail on me and I just got in on the newegg 6600GT deal. But if I am fine with my current PSU running all the components I listed above, then I won't make an unnecessary upgrade. However, if people tell me otherwise, I wouldn't mind shopping for a PSU that can handle more.

I just want to be cautious before I power everything up.

The 350w Antec should actualy be enough. I had a 2.8ghz prescott overclocked to 3.5ghz, with raid-0 raptors, and a 6800GT overclocked to ultra speeds running on a 350w Enermax.

but did that enermax have a 16a +12v like his 350 watt?
