Check the 12 volt current rating(in amps or watts) and let me know what else is in the system.
In general any quality 300 watt power supply is more than enough for a GTX 650 and even a 650 ti with a lighter(lower power) system.
My media center is happily running on a 300 watt power supply with its GTX 650 ti. Again my system was built for low power.
It is all about the 12 volt power for modern hardware, while many cheaper/older power supplies do not offer as much 12 volt power and place more on the now less used 5 and 3.3 volt rails.

the i3 3240 is very power friendly.
While the power supply is rated in watts, it delivers more than one voltage. We need to know how much of that 400 is dedicated to the 12 volt rails.
In this image you can see the power supply has 22 amps @ 12 volts and 22 x 12(the formula to turn amps to watts is amps x voltage) = 264 watts @ 12 volts.
So lets see what you have.

here is what i have
the only thing that is written on the psu is
acinput: voltage current frequency
180 v 4a 47-50hz
264v
dcouput: orange yellow blue red white purple blue green brown
+5v +12v -12v +5v +5v +5vsb com ps-on pok
18a 14a 0.5a 32a 0.5a 2a cnd ----- p g
WTF is that???

If I see it right, you are looking at
You seem to have 2 x 5 volts rails? That does not make sense. 5vsb is normal. It also does not seem to show a 3.3
Can you by any chance get an image of it?
Unless it is a typo(guessing it is with orange being 3.3) and it was supposed to be
3.3 = 18 (60 watts)
12 = 14 (168). If this is true the power supply is quite old and not designed with modern systems in mind.
-12 = 0.5 (6 watts)
5 = 32 (160 watts)
-5 = 0.5 (2.5 watts)
5sb = 2 (10 watts)
I think you would be pushing it a bit. This is not to say such a system would not run(system may not even take 160 watts), but I can not recommend a power supply with so little extra just in case power. Parts have higher peak power at times that may overload that power supply
The power supply in the image above is "only" 300 watts, but the newer design allows it to have MORE 12 volt current[22 amps vs 14] and turn unused 12 volt current into the lower [5/3.3] voltages when needed[as long as the total of all rails do not exceed 300 watts]

If you want to play it safe, this Asus GTX 650 needs no PCIe aux power cable. It gets all its power from the PCIe X16 buss. That would be your safest choice if you don't change PSUs.

However, this new GTX 750ti is the fastest card available that doesn't need a aux power cable now (60W):

I just bought one for a budget build I'm working on.

The GTX 650 is only a 64 watt part anyway, that is within the 75 watt pci-e power envelope. I can only assume some companies have had issues with not getting enough power from the slot in the past to even bother putting a 6 pin on the card.
Do not get me wrong the 750's are great cards for the price.
As for power supply, If it is this you are looking at, It has more than enough power(480 watts @ 12 volts in a 40 degree environment) for even higher end cards so would give you no problems and power to spare.
