Antec 450W PSU good enough?

[Apocalypse23]

I read somewhere that 450 might not cut it for overclocking the 170..Iv'e had no problems with this 450W Antec PSU before when I had my 64bit 3000+ ocd at 2.6ghz, while running one cd rw drive, three hardisks, a sapphire 1950xt 256mb, 2x1GB pc3200 OCZ performance memory, dfi lanparty ultra D mobo, a soundcard and a tv card.

Also, I've got four fans running in the case and for the cpu.

Now I've installed the 170 so far, just waiting on my second ram stick to be rma'd, but do you think the setup I have would be fair enough for a stress test for the Antec?

Personally I think it should be a breeze, your suggestions?

Thanks

Alright, I am planning on selling both my 7800gt and 1950xt, ill be getting a 8800gts now, so will this 450watt still cut it?

Looks to me the minimum psu requirements on the evga site under the 8800gts is 400W, now do you guys still think it will manage it?

Thanks again!

While a GTX requires more 12v power than a 1950XT, the GTS doesn't. Any psu that will run an X1950XT will run an 8800GTS.

Looks like a tricky situation here, I'll have to test the PSU I have currently first with the 8800gts and then decide, I've looked all over and can't find any confirmed reports of users testing a 8800gts with a 450 antec SP PSU.

Got the OCZ GameXstream 600W PSU, the 450W ran fine, but I noticed it was easier to overclock the video card with thte 600W PSU. So far I have the following set up:

evga 8800 GTS 640MB - overclocked the beast to 600/1800 MHz
opteron 170 dual core - overclocked it to 2.90 ghz so far, might reach 3.0 stable with current ram and PSU, have yet to try.

I have only one thing to say...

I LOVE THIS SYSTEM!!
