Will a CoolerMaster 450W power this rig?

[martensite]

I recently upgraded my CPU, mobo and RAM and added a HDD so my rig looks like this now.

C2D E6550
Gigabyte P35-DS3R
2x1GB Corsair ValueSelect 667MHz
2x Hitachi 160GB SATA-II
1x250Gb Seagate 7200.10 SATA-II
1xBenQ 1640 DVDRW
1x7800 GT 256MB
Logitech MX518 (USB)
Saitek Eclipse keyboard (USB)
1x80mm and 1x 120 mm case fans

All running bone stock, and powered by a CoolerMaster 450W Real Power PSU.

No overclocking planned either.

I've temporarily removed my PCI TV tuner card and Audigy 2 soundcard as I was not sure if the PSU can handle all the load.

I am going to upgrade to a 8800GT and I'd also like to put my 2 PCI cards back in the case.

Will the CM450W be able to handle everything smoothly, or is there no headroom left?

Also, any advice on what could be a (possible) replacement PSU to handle this rig would be greatly welcome.

Don't see any issue.

30a should suffice for a 8800gt, 4 hd's, 2gb of ram and a non-oced e6550.

Thanks for the replies.
I have just got a 8800GT so I shall put it in and see what happens.
Incidentally, I also found an irresistable deal on a Silverstone Zeus 750W unit, and it ought to be delivered tomorrow, so my CM450W will have to run this only for a day.

BTW, MarcVenice, what did you mean by 30A should be okay? Sorry for the n00b question, but is that 30A on the 12 V rails peak or continuous? The CM450W has 16+18 A peak and 10+12 A continuous on the 12V.

30a peak would do it, but continuous 30a would be better.
