I am building my first computer and was wondering if an
enermax 350w PSU would be alright for a system with an a64 3000+, 7200rpm HD, radeon 9800pro, DVD and fans and crap
 
Probably, but to be on the safe side, I would recommend a 430 or 480 watt ps.
 
since both tha xp64 and the ati9800 recomend atleast a 350 watt psu, i would setup up to a 431w or better.
 
where did you fnd power recommendations for a64? i looked around on the amd website but they didn't have god specs like they do for athlon xps.
 
get the 431W and you'll have no problems and be ready for future additional devices for that system!

you are right, amd for psu requirements said this.
In our ongoing efforts to support industry standards, AMD Athlon™ 64 processor-based motherboards may be designed to leverage industry standard power supplies. The selection of the proper system power supply is a critical element to the success of the finished system. For best results, a system builder should always contact the motherboard, power supply, and chassis suppliers or vendors to verify that each of the chosen components supports the desired system configuration, and a system builder should verify that support through internal testing and validation. Depending on the motherboard vendors' design requirements, the servers and workstations built using AMD Athlon™ 64 processors are designed to leverage industry standard power supplies. Please reference your selected motherboard form factor to ensure power supply compatibility. The system builder must ensure that the total combined wattage for the system configuration must be less than the output of the power supply used. Overall current usage limitation on the power supply should not exceed a combined system power output for the +5V and +3.3V outputs. Note: It is imperative that system builders ensure that the power supply of choice, motherboard, and the selected chassis are mechanically compatible.

but all of the mb i have looked at Tyan and Asus say 350 watts and tyan said atleast 350 watts.

hope this helps.
 
Why do you want to pay a whopping $59 for just a 350W PSU, and an Enermax at that, when you can get a first class Fortron/Sparkle for over $20 less? For that much money you can even throw in a Hi-Q or PowerQ 350W PSU, made by Fortron/Sparkle, as a spare. Do you really need the 24A @ +12V offered by this Enermax? And if you do, realize that 350W will leave only 62W left for the +3.3V and +5V, although that'll probably be enough. But considering that Enermaxes don't seem to be as underrated as Fortron/Sparkle PSUs, I don't think they're worth $59.

Takaman's power needs estimator can help you figure out what you really need, not only overall power but the number of amps from each voltage rail. And unlike most estimators it doesn't seem to grossly overstate the needs.
