Power supply help

Hey, im in the computer market and i'm not sure exactly how much power i'm going to need. The components are
AMD XP 1900+
Radeon 8500 AGP
Soltek SL-75DRV2
Modem/lan card
30 gig h.d.
100 MB zip internal drive
Santa Cruz sound
Koolance water cooling case
256 MB DDR ram
3 1/2 floppy
50X cdrom drive
cd burner

Im also thinking about over clocking and adding a few fans. I think 400 watts would be more than enough but im not all that sure. Also, enermax and antec are my top choices for the power supply. Thanks

Do you work at UPS? 'cuz i could have sworn you were checkin out my package!

The two best makers of power supplies for home systems are PC Power & Cooling and Enermax.

No Antec PSU is comparable with the offerings from either of these two companies. I've got a pile of 'em in a box in the back of my shop. I like to strip the connectors out of them and make extensions. That's about all they are good for, IMHO. I wouldn't put one in the system you are describing unless you forced me at gunpoint.

These are the best:

Enermax is a cheaper PSU, but it's also the best for price/performance:

I wouldn't put less than 400 watts into that system, and more would be even better. Most people don't consider <i>redundancy</i> when ordering a PSU. The rule-of-thumb, from an electrician's standpoint, is 30% redundancy. That's means your system shouldn't pull more than 70% of the PSU's total running output for performance and safety.

This is the powerplant for your entire system, and it's got to last a few years. So don't skimp. Get a good PSU, with a decent warranty. You'll be glad that you did.

The Koolance case comes with a water-cooled PSU. Try that first, and it doesn't work, see about getting something else.

You're right, I just looked at their website. Well, never mind then. I just bought a 431w Enermax though, if that helps you decide any.

Yes, I have a 431W Enermax Whisper as well. They are great PSUs!!
