If you won't be expanding on that build I'd go with something around 500w-600w. The Corsair VS series is very cheap but you could always go for the CX or CS series depending on how efficient and reliable you expect your build to be.

For a system using a single GeForce GTX 650 graphics card NVIDIA specifies a minimum of a 400 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 20 Amps or greater and that has at least one 6-pin PCI Express supplementary power connector.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Sufficient Total Combined Continuous Power/Current Available on the +12V Rail(s) is the most critical factor.

What is your PSU budget?

Here's an example of a PSU that is way more than sufficient to do the job:

Seasonic G-Series 360W (SSR-360GP)
• OEM: Seasonic
• maximum combined +12 Volt continuous current rating of 30 Amps
• one 6-pin PCI Express supplementary power connectors
• Modular Output Cables: No
• Official Intel Haswell Compliance: Yes
• 80 PLUS GOLD Efficiency Certification
• 5 Year Limited Warranty
