You have two 18A on 12V rails. So, that's enough to run a single GTX460 without problem... :)

The GTX460 needs around 10 - 12 amps for itself. That 24 amp "requirement" is for a complete "typical" (whatever that means) system.

One of my systems has an OC'd Q9550, 4 GB RAM, a GTX260 - a card with similar power requirements to yours, a Gigabyte EP45-UD3P motherboard, 3 hard drives and an optical, and a Soundblaster card all powered by a Corsair 750TX.

Running 3 instances of Prime95 to load the CPU and 3DMark06 to load the GPU, it pulls 375 watts from the wall as measured by my Kill-a-Watt meter. Figuring 80% efficiency, the system pulls 300 watts from the PSU.

Assuming the PSU is working properly, you will have plenty of power.
