How much power do I need for this setup?

[hammondnav]

Here's the rig:
AMD Athlon XP 3200+ (conservatively OCed)
Asus A7N8X Deluxe Rev 2
2 or 3 RAM Modules (conservatively OCed / Not OCed)
ATi Radeon 9700 (conservatively OCed / Not OCed)
2x IDE HDD
1x CD-RW Drive
1x DVD+/-RW Drive
1x PCI Audio Interface
1x PCI Firewire Card
1x PCI Soundcard
1x Firewire Audio Interface
1x Internal 3.5" Drive with USB Card Reader
2x Papst 12mm Case Fans
1x Panaflo 92mm CPU Fan

Is 500W going to be enough? I wouldn't mind having a little juice to spare in case I expand the system in the future. Also this is going to be used in a small music studio so the quieter it is the better, but reliability and stability are very imporant.
Thank you for your help in advance,
Nav

500 is more then enough...I could see an antec or enemax as low as 380watts powering it even oc'd just fine....

I had a 430watt enermax that powered

p4 2.4@3.5ghz
1gb of ram (2x512)
Nvidia 5800U (oc'd)
1X raptor SATA drive
1x HDD drive
2x dvd-rom/burner
5 case fans and a large cpu HSF....

it also later powered my current system in my sig just fine.....

I have a 600watt OCZ now but I got that as a possible dual opteron or xeon was considered then later cancelled in favor of an extremely oc'd X2 system...

It probably consumes no more than 200W. Let's be extra-conservative and call that 250W. Add in label fudge factor and upgrading headroom and you'll be fine with a high-quality 400W-430W unit. Seasonics are nice if you want reliability and quiet.

Thanks a lot. Seasonics it is... it was in my top three anyway along with Antec TruePower 2.0. Antec Phantom is silent, but I can't find good reviews on its performance. It's pretty pricey too ($176 shipped from NewEgg).

I'd also suggest Fortron as they have some well-priced quality units that would power your system very easily.



No need to break the bank wth this PSU.

Fortron and Enermax noisetaker V2.0 would be my top choices...400 to 500w range.
