New Phenom Build: Power Supply Question

Despite the mixed reviews, it was time to get off this old AMD Athlon XP 3000+ system and get with the new stuff. I'm going with the Phenom 9850 on an Asus M3A-32 MVP Deluxe, w/ 2 GB Crucial DDR2 1066 RAM. Going to use an 8800 GTS 512MB vid card.


I've got a 450Watt power supply which is fairly new laying around, would this be fine for this system? Won't be a problem to go get another one, but while I'm waiting for this all to be delivered I might as well find out. I don't plan on overclocking (at least for awhile), so I was hoping I could just use this this ps. Any recommendations would be appreciated, thanks.

I believe these are the stats, not sure exactly which would be what.


Mad Dog MD-450WPS
+3.3V = 22A
+5V = 45A
+12V =20A, 240W
+3.3V & +5V = 213W
+3.3V & +5V & +12V =430W
-12V = 0.8A, 9.6W
-5V = 0.5A, 2.5W
+5VSB = 2.0A, 10W
-12V & -5V & +5VSB = 22W

Thanks for the info, if it boots and works I'll save me a couple bucks I guess . I don't want to make another thread, but considering this system is A LOT newer than my current, what should I use for an OS. I'm unsure of these 64-bit versions of XP and Vista, I have 32 XP on the Athlon XP 3000+ and 32 Vista on my Presario Turion 64 X2 2.0ghz laptop... I don't game as much as I used to, but I want what will work.
