BleepingComputer.com: Upgrading Video Card and need to know if I should upgrade my PSU

So I've had my computer for a little over a year and a half now, custom built. I have managed to get together some money and am looking to upgrade my video card to a newer one, and was wondering whether my current power supply would still handle it, or whether I will need to purchase a new one too.

My current specs are:

CPU: 2.4Ghz Intel Quad Core #Q6600
Motherboard: Gigabyte LGA775
RAM: Corsair 2x 2GB DDR2-800
Video Card: Gigabyte 8800GT 512MB
Power Supply: Highpower (HPC500-G12S) 500W
HDD: 1x Western Digital 500GB and 1x Western Digital 1TB

I'm looking to get a Gigabyte GTX275 896MB Video Card. Would my current power supply still be able to power everything or should I really look at upgrading that too? and if so what should I upgrade to? Preferably something not too expensive though.

It should be able to handle all that stuff.

You should be able to handle it, though, make sure your case has enough room for a GTX 275 as it is 10.5 inches long.

Well, the manufacturer recommends alteast a 550W power supply for the GTX 275.

According to various tests, the GTX 275 draws around 180W at idle and around 320W under load.
It clearly is power hungry compared to the ATI cards it competes with.

You also need to determine how much power it draws from the 12V rail.

EDIT: Here's the stated power requirements:

So I would recommend a decent 600W (+) PSU for your system.
