I am working on a new Rig.
I have currently an Antec SL 350 Power Supply, but suspect it will not be enough. I have sat and crunched few number. Below are they. Hoot I am looking for a recomendation of a power supply for all this and future upgrades and additions to the rig.

Tell me how much wattage would be sufficient for below Rig.
I want to OC the Athlon to close to 3 Ghz Speed, but bus will remain on 333 FSB, not OCing Ram.


All Fans and Cathode Tubes = 38 Watts
Laser LED = 3.12 Watts
Floppy = 5 Watts
Adaptec SCSI Card= 20 Watts
Earthlink 10/100 Card= 4 Watts
1 X CD/dvd/cd-rw uses 25 Watts= 25 Watts
Motherboard Without CPU or Ram= 40 Watts Max
Ram 8 watts/ 128MB (728/128)X8= 48 Watts
AMD Athlon 333 FSB 2600+/2700+ wattage= 68.3 watts
IBM UltraStar SCSI-3 HD 22 Watts for 1 SCSI-3 * 4 HD= 88 Watts

+ Not to Mention External USB Powered Devices. Have not counted them.

Grand Total of Watts Req = 339.12 Watts

Welcome to the forums.
The 350 should accomodate what you are running now, but as you plan on doing some overclocking, consider a 450W or up. You have to bear in mind in your calculations that every component is not using maximum juice at one time.
 
Thanks Stool

I am sorry this is a repitative thread, and I requested to be deleted. Some how it gave me an error first time I did "Submit post", but posted anyway to forums.

I sugguest everyone who wants to respond to reply on that thread just to keep things organized. Sorry for the trouble.

As for the Power Supply, I was browsing refurbished section of Newegg and ran-into 550 Watt Enermax, with free shipping for $99. I could not resist. :cool: Should have that in the new rig by end of next week.

Thanks for response.
