Is My Power Supply Strong Enough...

I have a 200watt power supply and I was wondering if it would be enough for a Duron 700 on a KT7A, with a Radeon 7200. Also there's a burner and two hard drives and a couple of case fans.
 
It's a Dell power supply. I'm assuming that's pretty good? :rolleyes:
 
Dell is the Britney Spears of PSUs.
I am running the following on a stock Dell 250w(the Britney Spears of PSUs):
P4 2.4GHz
640MB DDR SDRAM
GeForce 4 MX 420
2x 7200RPM 60GB Western Digital HDs
PCTV Pro
48x24x48x CD-RW
50x CD-ROM
System is stable even with both CD drives going, distributed.net running(I crack RC5-72 for OCAU), and HDTV open(nothing overclocked).
Voltages(measured with a radioshack DMM):
12v: 12.06
5v: 4.99
3.3v: 3.30
BTW, I reverse engineered an old dell supply from a p133.
That dell supply used a LITEON power transformer(at first, I thought they only made CD-ROM drives).
There is only one switching transistor(well, only one big primary transistor, as there is a smaller transistor in the 5VFP supply, and several big transistors on the secondary side), but it is a high-power IGBT boobie(20A, 900v) in a TO-3 case.
The primary caps are 680uF each, for a total of 1360uF(most PC power supplies have only 2 470uF, or 940uF total)!

I wish my power supply could turn into Brittany Spears. Maybe I should get a Dell.
 
Hmmm.. this and the sticky post were incredibly helpful.

I'm putting together the rig in my sig, with standard additional components (DVD, CDRW, 1 HD).. almost bought a new PS, but then looked at the specs on my PS.. Antec SL300s with 220w on the 5+3.3 rails.

Thanks for explaining out the Britney Spears comment, otherwise I would've considered the Dell P/S was nice looking, but trashy.
