Is this 500w supply ok for this Video Card?

Specs: Windows XP
Im looking at buying a video card for my pc.

The card I have set my eye on is PNY GeForce 7900 GTX 512mb. PNY website recommends a power supply with 12v 22A rating for this card.

I have this http://www.xpcgear.com/s500v20bf.html power supply sitting in my mother-in-laws pc, will it be enough to run the above card and my system. This supply has 12v1 16A and 12v2 17A. Does it mean that together its 33A supply?

I have a Lenovo ThinkCenter 8811 which currently has a 310 watt supply installed. If the above supply is ok for this card I will swap supplies with her.

My system specs are:
Intel Core 2 Duo E6700 @ 2.66ghz
Northbridge Intel Q965 rev. C1
Southbridge Intel 82801HB/HR (ICH8/R) rev. 02
Memory Type DDR2
Memory Size 4096 MBytes
System Manufacturer LENOVO
System Name 8811DE2
Mainboard Vendor LENOVO
Mainboard Model LENOVO
BIOS Vendor LENOVO
BIOS Version 2JKT30AUS
BIOS Date 01/24/2007

Board has a PCIe 16x slot.

2x 500GB Hard drives and one DVD burner

why do u want a old card?
Stick with your current psu and buy NVIDIA 240GT GDDR5 or ATi radeon hd 5670. Both cards mentioned outperform 7900gtx.

"why do u want a old card?"

Exactly what I was thinking before I even saw kuwese's response.

"This supply has 12v1 16A and 12v2 17A. Does it mean that together its 33A supply?"

Not exactly, but it *should* work. NSpire isn't a brand I've ever heard of before though.

Mainly power ratings and cash limits.

I just thought newer cards were out of my reach cost and power wise.

The GT 240s will work on my current power supply.

Thanks for your input.

"The GT 240s will work on my current power supply"

And the GT 240 (preferrably with GDDR5 memory) will beat the crap out of the older 7900 GTX. Even the GT 240 w/GDDR3 is better. See the chart:
