Do you think this PSU could handle a GTX 460 graphics card?

I am about to purchase a new graphics card for a pre-built HP system, but I want to make sure I don't push my PSU too hard. I think it will be okay, but want to double check with the gurus. I am not interested in updating the PSU at this time and am fine just going with a less-intense graphics card. A GTX 460 requires a minimum PSU of 450W. Could this system handle a GTX 460? If not, which would you prefer, the new GTX 550 ti or a Radeon HD 5770? Thanks for your advice!

System: Core-i7-920 (B) (2.66GHz /1366 MHz) 1 MB L2 + 8 MB shared L3 (130W), 6 GB (3 x 2 GB) DDR3 PC3-8500, PSU 460W, and 640 GB 7200 rpm SATA 3G (3.0 Gb/sec) hard drive.

PSU: AcBel
Output:
+5.0V = 13.0A
+3.3V = 17.0A
+12.0Va = 16.0A ---|
+12.0Vb = 15.0A ---|---Total 385W @ 50 degrees C Max
+12.0Vc = 8.0A ---|
-12.0V = 0.8A
+5.0Vstb = 2.0A
Total 460 W @ 50 degrees C Max
Total 350 W @ 60 degrees C Max

There is a 6-pin connector available and a few 4-pin connectors that I can use a Molex (sp?) adapter on to power the second 6-pin power supply on the card.

32a on the 12v will power the GTX 460 and i7 (assuming the PSU can actually deliver that power). acbel makes lower end PSU for cooler master and gigabyte. those units are not known for great efficiency. personally i would go with another known brand

You can get a HD 6850, only 127W on load and it's fast. A factory overclocked GTX 460/1G might reach 180-200W.

450W at 50C max which lowers to 360W for a 10C rise in temperature does speaks highly of the PSU's mediocre quality.. Better replace it quick with something a little more substantial.. IMO, an OCZ unit will do better..

Radeon HD 5770 will draw the least amount of power if that is of concern.
