I bought had a cooler master 380 watt psu about 2 months ago, long story short its dead. My guess is either i need a bigger one ( 500-600 watt) or a better name brand.. anyway heres my build.

ATX coolermaster case
Pentium 4 3.0 prescott
Ati Radeon 256mb agp video card
80 gig hard drive
3 120 mm case fans
5400 rpm 80mm cpu fan (thermaltake polo 375)
4x512mb pc3200 kingston ram

If somone could please help me pick a good psu brand name and size for this build that would be awesome! thank you. I also change things around alot in the case ( add more ram, add a new video cards/ fans ect.. ) i really want a reliable PSU thats not gunna **** the bed within a few months.

Antec's TruePower are supposed to be really good.

I only have generic PSUs so I can't tell much more, except that in my case a 300W(or is it 250W?) can power an Athlon XP 2000+ Palomino and a GeForce 4 Ti4200 w/o problems.

yeah i heard antec is pretty good.. im looking to spend at most 80 dollars if anyone has any suggestions please..

Thanks looks good

I love the OCZ ModStream 420W :grinthumb

Modular Design: So you only use the cables you need!
Sleeved: All the wires are sleeved in a UV-reactive cable.
Silent Fan: A single 120mm fan keeps the unit quiet yet cool.

Definitely google it up.

Maybe SmartPower is a good one but we hear about a lot of problems with these.

Enermax is better than a standard one also. It's silent.

You don't have to spend a lot to get a good psu, here are three good ones, that are pretty cheap.
