How big of a power supply would I need for this setup?

[Jay59express]

After having troubles with my current PC, I think I am going to upgrade the major components, new PS, motherboard, processor and ram. Just wondering what a good power supply for this setup would be:
1700+ retail HSF
256 MB pc2100
3 7200 RPM hard drives
Geforce 2 (Geforce 4 Ti4200 soon 🙂)
2 USB devices
Sound Blaster Live
10/100 card
modem
Burner
CD drive
Floppy
Ultra ATA 100/RAID card

Is a good 300w PS good enough, or should I go with 350w or even 400w? Nothing in the system will be overclocked.
Thanks!

If you are going to buy one regardless, get at least a quality 350w (Antec, HEC, Sparkle) since it is only a few buck more than a 300w.

As John said spend the extra "few" bucks for a lot less headaches... 😉

Why invest several hundred smackers in good componets and then buy a cheap PS...?

I have about the same amount of stuff in my rig. Go for 400w.

If you have Excel or similar program that can use .xls files try the Watt Calculator I found, right click to save as or use online.

350W will be plenty of power

350W will be more than enough, remember it's the quality of the power supply that matters most. 400W would be overkill, plug it's more expensive.

I've run 6 SCSI drives in a RAID with a dual proc Intel board and using a 300W powersupply. AMD runs a bit more power though... 😉
