PSU wattage

[mattaggie]

Pentium 4 3.0 GHz 800 MHz FBS
BIOSTAR P4M80-M4 Socket 478 VIA P4M800
Ultra 3200 RAM 1 GB
Lite-On DVD RW
Maxtor 250GB SATA/150 HDD
56k/ v.92 fax modem in the PCI slot
TR2-430W Thermaltake PSU

How big of a power supply do I need for this system? I am thinking the 430W may be overkill and I can put something smaller in and use the 430W elsewhere. How do you know how big of a PSU is needed?

I take it you're using the motherboard's on-board video, and not a dedicated video card since you don't list one in your specs list.

If that is the case, I'd say you could get away with a decent quality 350w unit for that system. But if the 430w Thermaltake is working fine, why bother replacing it? The TR2-430w you have only conforms to ATX1 standards, so it's unsuitable for a modern build. I wouldn't recommend replacing that decent quality unit for a low-quality 350w unit.
