yes penguin is right even if you had a video card that requires power
that power supply will work fine.

Your fine but if you do a seerious videocard upgrade (we are talking x1800 or x1900 here) you will probably need a bigger power supply.

But as a refrence i am running a 7800gt an AMD 3700 with 2 gigs of ram on an Asus A8N-e with a 480 watt antec.

No, not really that 450w is pretty much fine for any single gpu system... the only reason to upgrade the psu would be if he went SLI or CF or had like 6 raptors in raid0 and 10 fans and 4 cold cathodes and a water cooling rig which ran off the 12v line.

I'm running the rig in my sig on a NeoHE 430W...

I'm also running a 3200+, DVD/RW, 1 SATA HDD and HiS X800GTO in an Antec Sonata II with the SP II 450W. Running a 15% OC on both CPU/GPU 24/7 - runs smooth as butter.

Plenty of power for that system. The 3800 X2 will use around 65W stock, and if you have a 1800XT it would be around 100W. So as long as you have a good 12V rail, or two, you would be just fine. I ran a 7800GTX SLI 165 OCed system on 480W Neo Power... never had any issues.

It will be good, most times systems don't got over 300 or 350 watts. One thing you may have just had a stupid on is you've got an am2 mobo and ddr2 memory but you said a socket 939 processor, you'll want to get the am2 version of the 3800+.

the NeoHE 430w delivers more 12v power than the 450w smartpower.

More 12V or not, the SPII 450W is capable of running the rig he is planning.

yes. but you were making a point by saying your lower wattage 430w PSU could run a better system. I was pointing out your 430w trumps the 450w

Then I should have been more clear. I was giving two examples of relatively low-power PSUs that are easily powering high-end systems. At least low-power compared to the 600W+ PSUs that are currently on the street.

It's baking over here - day and night. I come from hot/humid weather - right on the coast of the Gulf of Mexico - and this heat slaps me in the face! And the worst part is that the hottest month is right around the corner.... :mad:

I'm right on the coast of the gulf - it's not as humid as Mississippi, but it's not as dry as Arizona.

I don't know what the big fuss is over huge power supplies these days, you guys got nothing on my 385W system, it runs like a charm. Just look at the specs below..
