Question about Upgrade to GTX295 and PSU

[x-spades-x]

I want to upgrade my 8800GTS to a GTX295, but I have a question about the recommended power supply.

According to nVidia(http://www.nvidia.com/object/product_geforce_gtx_295_us.html), the GTX 295 needs a 680Watt power supply, however, after doing some research, i believe my current rig should run it just fine without upgrading my current power supply and was just looking for some clarification.

Current Rig:

Motherboard: DFI BloodIron P-35
CPU: Intel Core 2 Q9550
Memory: 8Gigs OCZ Fatal1ty Edition
Sound Card: Creative Sound Blaster X-Fi Titanium Fatal1ty
Hard Drives: 2 Western Digital 300G VelociRaptor's in RAID0
Current Graphics Card: Evga 8800GTS
Power Supply: Antec Truepower Trio 650W (http://www.antec.com/Believe_it/product.php?id=NjI=)

So from what i read, my power supply puts out 57A over 3 12V Rails, so therefore should run the 295 fine, but like i said, I would like to know before i buy it.

Thank you In Advance.

In theory your Power Supply will handle the GTX295 because this card needs recommended power supply with +12 Volt current rating of 46 Amps.
