Is Corsairs HX 620W enough for Desktop below? Good?

[ghostmann]

Hey guys let me know if this will work with my specs below. Getting a good deal on this from my local computer store (Compusa) is closing down. Getting it for under $100. Its replacing my old Antec NEO HE 550w after I upgraded my processor. Is 620watt enough

Q6600 @ 3.0
zalman cpn9500 cpu cooler
D975XBX rev 304
2 gigs DDR2 800 overclocked crucial ballastix
2 HD3870s in crossfire
2 74gigs raptors in raid 0
audigy 2ZS
4 92mm fans
DVD rom Burner
CD rom Burner
floppy drive
2 USB powered accessories keyboard (logitech G15) and mouse G7 (battery charger hooked up to USB)

Thanks,

It's probably good enough, but may might be running under a fairly high load sometimes.

BestBuy has the 750w Corsiar for $119 right now and would be a steal.

I'd say it's cutting it close...but then again it's a Corsiar...

I think you'll be fine.

The corsair 620 is a monster of a PSU... and the draw from the 3870's is relatively low compared to some other highend cards. You should be fine although it doesnt leave much room for upgrades.

I would look at PCP&C 750W

You will be fine. Its a nice brand name PSU.

bestbuy has no corsair power supplies on their website?

You're absolutely fine with that Corsair. Q6600 draws about 110W at 3.0Ghz while 2x3870 = about 220W, add about 100W for miscellaneous components and that's roughly 66.6% (repeating, of course, heh). Its very stable (voltage-wise) and there is hardly any ripple at all:

If you have money to burn, buy a new PSU, otherwise stick with the awesome unit you already have.

I've got about the same setup with that PSU, but with 2 8800GT's. It works fine...

Heck I could run that on my HX-520 if I wanted to.
