Please dbl check your specs (look right on the label on the side of psu),
if in fact there is only 10a on the +12v, then it is not sufficient
to power your system.

But, dbl check & post the actual specs from the sticker on the psu.

If it really has only 10A 12V rail thats a hideously awful PSU. In fact it's remarkable that you got an i5 and any graphics card to work if you only had 120W to play with.

Any good 400-500W PSU will be way more than sufficient. Antec HCG range, XFX Core range usually start below $50. If not, there is always the Corsair CX range which is perfectly serviceable.

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.
