Yes your PSU should be able to handle the 285...
Have you overclocked your CPU ?

Please list your all hardware.
We will calculate what you need on the 12v rails.
The specs for the GTX 285 call for a 650W PSU, but you still may be able to handle it with your PSU.

You need a power supply with 27 amps on the 12v rails.
Adding the rails on this power supply comes to 29. The real figure should be about 27, so I think you are okay. I don't see a combined 12v rail figure for this PSU.
One more or one less amp is fine. There is a safety margin.

There is no toughpower 500W. What model do you have?

A gtx 285 uses about 17 amps and 204 watts at max load.

While your PSU isn't especially strong, it should be able to handle it fine. Don't try SLI, though.

 


Edit: Wait, does your PSU even have PCIE connectors?

That PSU will not be suitable. Get a quality 500W+ with 2 PCIe connectors. Antec Earthwatts 500 or Corsair VX550 would be good choices.
