Will My Psu Handle This System ?

well in few weeks iam upgrading my pc and wanted to ask if my psu can handle it.
I have Corsair HX620W PSU, is it going to handle this final build ? ( old and new parts included )

- C2D E6600
- 2GB Corsair RAM
- 250 Gb Seagate Barracuda
- Evga 7900gt
- Sound Card: X-Fi Fat1l1ty
- DVD Drive
- Floppy Drive
- Gigabyte GA 965P-DS3 iP965, S775 ( not sure if its going to be this mobo )

 

Yes it will, You can run a 8800gtx on 550w. It will easily to run

 

well what i heard was its about AMP's not W for GPUS so thats why i was wondering.

'' +3.3V line can deliver a maximum current of 24 Amps and the +5V rail 30 Amps. '' Is this good for my psu ?

 

It will definatly run, As long as you have enough Ws, If you had like a 250w then it wouldnt

 

it should be able to run.

 

swap the board for an ASUS p5n-e SLI
if possible, go for a 8800GTS, they go for around 250 right now...

 

u sure its 8800 for 150?

 

that was a typo i meant 250

 

Definitely.

Corsair 620W can even run 8800 fine.
