Will 300 Watt Codegen Be Enough?

The Computer will be this:
Case: Ultra Wizard Black Mid Tower
Ram: 1 Stick DDR400 512MB
Processor: AMD AThlon 64 x2 3800+ 939 (overclocking to 2.6 if it works)
Motherboard: Machspeed NF4
Graphics: x800XT (Overclocked? Maybe)
Hard Drive: Ide 7200 RPM 40GB HD
DVD Drive: Just some generic DVD DRIVE
Mouse: USB Optical generic microsoft mouse
120mm fan and a cooling fan for cpu.

According to the psu calculator it needs only 273 watts to run this machine.
with all the things posted above.
*The antec 300 watt didn't have a 4 pin cpu power plug so I swaped the codegen out of my athlon xp rig since it did. I have a 20-24 pin converter also.

hells no. Dgood come on man did you really think I wouldn't see this? Your overclocking not one but two components and you don't want a good PSU?

I put that last choice in for you.

I just don't have another psu atm and I thought I"d see if it boots I wont' actually oc anything until I have a better one. I just had all the parts and they fit just don't have the processor till next week sometime. It's really all just to test the rma'd motherboard.

well you should have said that, now you made me look like a meany.

Anyway, for short term, heck yeah it'll do fine. But no overclocking. I kept an old 20piner around for Troubleshooting. Then I sold it in a box o crap to someone here. Hmm got to get an old junker now.

for your sake and my 70 dollars of total input into this computer of late the question still stands what are other people's opinions will it run windows stably and maybe a game?

Should be okay. I wouldn't stress it much more than that though

If i understand the PSU calculator correctly, the wattage shown above is with the processor running at 85% of its TDP (aka not full load).

So definitely don't do any overclocking, but it should just about work ok for now.

it over estimates a little, usually by about 10%.

that and even at 100% TDP with another fan on top of what is listed, it says 288 Watts. Seems that Ide harddrives are what keep the wattage down lol. Cuz when I asked this question before I had it with sata on the antec before I realized I couldn't use the antec. It said like 303 or something.

It is under estimating the TDP and only used 85%... Also without including standard deviation, it is always, always, and always under estimated.

No real engineer would ever do proper PSU sizing without standard deviation. Some of us even add extra standard deviation to our deviation estimation but mostly only to military grade hardware. --> 100% sizing for standard hardware, 105% sizing for military hardware.

BTW, in case it isn't obvious to some here in this forum --> The PSU calculator defaulted to 85% sizing.
