Will my PUS support a gts 250?

Hi all.

Looking at a GTS 250 512mb.

Current PC specs are:

Intel Dual Core E5200 o'c 3.0 @ 1.28125vcore (bios)
2 x SATA 2 250gb HDD
1x DVD-RAM
Cooler master Hyper TX2
Ga-EG 31 m-s2 MOBO
2x 2gb DDR2 800 Ram (stock v and timings)
585W ODIN Gigabyte Psu (34a on 2x12v rails; max continuous output 460w, max rated 585)
+- 4 months old so negligible capacitor aging, single 6pin pci-e power cable)

So.. will that PSU with the GTS 250 be stable, and not pushing the envelope? I'll prob go back to 3.33ghz when I get the card to prevent CPU bottleneck, so I need to factor that slight power draw increase in too. At 3.33, to be prime stable I gotta put CPU at about, offhand, 1.38vcore.

Thanks in advance.

the link to antec said 270w. Im happy if that true, but not seem abit low?
