Who's telling you to buy a new PSU?
If your 350W PSU has sufficient combined +12V capacity you don't need a new PSU.
NVIDIA's own recommendations is a 300W PSU minimum. (Minimum system power requirement based on a PC configured with an Intel Core i7 3.2GHz 130 Watt TDP processor.) An Intel Core 2 Quad Q9650 is a 95W TDP processor so it will draw less power.
Many people have run a GeForce GTX 750 Ti on the 300W PSUs that came with their pre-built consumer systems from Dell or HP without any problems whatsoever.
