Can Neo HE 500w handle this system or not?

[shooter124]

First of all I already bought the PSU (cause I found it for 40$ AR) and im waiting on a few parts (q6600) to complete the system. The PSU has 38A on the 12+ rails, but I'm just not sure if its powerful enough to run the system. eXtreme PSU calc says its going to be 472-492W with an overclocking Q6600 running at 1.35-1.4Vcore and thats not even with an overclocked 8800gts320.. when I put it on the slight overclocking 8800gts 640 (576 core) it puts it over 500. I know that the system won't be running at 100% all the time I just want to know if I should scrap the PSU to avoid problems before I build... here are the specs approx

antec neo he 500w
q6600 (overclocked to ~3.0ghz)
p35-ds3r
2 SATA HDs
4gb ddr2 800 ram
2 sata dvd-rws
x-fi with front bay
3 LED 120mms
1 120mm for the Enzotech Ultra-x
probably another 80mm fan
bay card reader
8800 gts 320 overclocked (~621/1900) or whatever i can get from stock cooling

and of course i'll be using usb devices and other things that will draw power

When I put in 30% for capacitor aging of the psu the requirement jumps to 650W++.. it says after a year of 24/ use thats realistic or thats what you should put it on if you're going to have the system for a few years, which I plan on doing... will it really be that inefficient? even without the capacitor aging selected its cutting it VERY close Should I get a bigger psu to cover my ass so my system doesn't fail/blow up? Thanks

can anyone help me figure this out please?

Since ur spending a fair bit on some decent components... may be wise to get a new psu also.

I got a 650w ~6months ago for ~$100AUD

Remember also, the more u push ur psu, the less efficient it becomes and the less it lasts.

Overclocking can greatly increase ur pwr consumption too.

Get a new one.

is 620w (50a) corsair enough even if im planning on upgrading video cards in the future... all of this talk of capacitor aging and inefficiency has got me worried and thinking I should spring for a higher output supply. I could get the toughpowere 750w for about the same price as the corsair.. any suggestions?

620w with 50a will do you fine as long as you don't SLI some GTX's or something crazy like that..
