Hello, I was wondering if my power supply is powerful enough to handle an upgrade I will be performing soon:

After the upgrade, the system specs will be:
Intel Core 2 Quad Q6600 w/ Stock Fan
2x EVGA 8800GTS 640MB (SLI)
Gigabyte NForce 650i SLI
4GB Crucial Ballistix DDR2-800 4-4-4-12 (4x1GB)
2x 120mm Fans
2x 92mm Fans
2x Western Digital SE16 320GB SATA (in RAID0)
Lite-on 20X DVD Burner w/ LightScribe SATA
8x USB 2.0 Ports
2x Firewire Ports

The power supply I was hoping to use is a:
Antec TruePower Trio 550W
[Three 12V Rails @ 18A Each - Total of 54A]

I built a system for my nephew recently using new and some of his old part: Q6600, EVGA 680I SLI mobo, 2x1gigs Corsair PC8500, ATI 1950XT, and 550w Antec. It wouldn't even boot with the Antec in, I had to put my backup 550w SeaSonic in it just to get it to run. You can try it I'm not sure if it was the same Antec 550w.
Here is a calculator that might help:

also note that this is continuous power not max power.

Hey Raven, do you think that PCP&C 610 could handle two 8800 GTS 640s? I ordered one from Directron two days ago, and I thought I would need a secondary drive bay power supply when I get my second (pre-owned) 8800 GTS 640 this week.
Seriously, I've never been so excited about a power supply as I am to get this one.

I used a Thermaltake 5.25 bay psu (250w) to run my second 8800 GTX, and it does fine for around $45 shipped.

Reviews were suprisingly good on both the quality of the unit, and the stability of the power provided.

About 7-10 minutes to install, vs pulling the 500w out of the bowels of my P-180 case and putting the new one in, past all the watercooling stuff.
