Need help to determine if 200 Watts is enough for this system I'm building ---->>>

Epox EP-8KTA3 (No raid)
AMD Duron 850 MHz Will be overclocked to over 1 giga Hz
Heat Sink: Alpha PAL6035C, Fan: YS, Thermal Grease: Artic Silver II
OCZ 256 MB, PC150 SDRAM, will be overclocked to 155~160 MHz
IBM, DTLA 75GXP, Storage capacity: 45MB
Matrox MGA Millennuim II, 4MB ..3 years old !!! (soon to be ATI Radeon)
Sound: Built-in AC97 Digital Audio (by VT82C686B)
CDROM: Toshiba 24X
CDRW: Plextor, 12X16X40
ZIP DRIVE: Internal SCSI Zip 100, with it?s own Adaptec SCSI card
Operating System: Multiple boot into Linux, Win2000, Win98 SE and the crappy WinME(maybe)
Current power supply is my case (200 Watts), I will be using my current case (Dell pentium 200MMX)

Everything is currently working great with the intel/200MX, will be getting the new MOBO/Duron, Sink/Fan and RAM this week end and will do the swap ... how much more juice does this board/CPU fan, will need !? I am guessing it should be OK !!
If not how would I know ??

AMD is picky. They suggest one of the CERTIFIED 300 watt power supplies.

I recently built a similar system with an Antec 235w ps, and it could not tow the line. The system would fail randomly, and at one point the cd's would not spin up properly. After switching memory, video cards and trading out the MB I got nowhere. I upgraded to the Antec 300 and *poof* the troubles went away. I run a K6-3 450, CD, Voodoo 3 3500 with the 235, but I steer clear of anything less than 300 for beefier systems. Hope this helped.

Spend some cash on a new PSU. The chances of that 200w working are one in a million.

Nope, that's not enough. You may get a LOT of problems. I suggest getting a Enermax 330w PS.

Thanks guy ... will order power supply now ... Do you guys recommend any brand/website !?

I like the Antec 300w, which is available for like $30 at Onvia.com (they use to have free shipping, now that's only if you order over $100 ). It's reliable and will definately get you where you need to go, for a great price.

That older case w/ P200MMX is probably AT form factor and PSU anyways, so you'd need to upgrade for sure.

I got my Enermax 350 watt from www.kdcomputers.com for about $50. The 300 watts will be cheaper.
