The official recommendation is for a 500 watt power supply with 36 amps on the 12 volt rail and two 75 watt, 6 pin PCI-e video power connections.

The Corsair VX450 is rated at 33 amps on the 12 volt rail and has just one 75 watt, 6 pin PCI-e power cable.

I know the GTX260 usually comes with a molex to 6 pin adapter so you could in theory convert two molex connections on the power supply to one 6 pin PCI-e connection.

There have been previous posts on this forum indicating some users have been able to run the GTX 260 using the VX450. A lot would depend on the configuration of the rest of the system and which games are played.

My best advice would be to consider getting a new power supply.
