Will My PSU (300W) Handle a nVidia GTX 650 Ti?

I have a 300W PSU and I'm not sure if it will be able to handle that amount of energy that the GTX 650 Ti uses. If I need to upgrade my PSU, then I will probably go for the newer GTX 750 Ti because it uses less power (correct me if I'm wrong).

No. nVidia lists the minimum system power requirement for a 650 Ti at 400w, and if I had to guess, the 300w power supply you're asking about was included with a prebuilt OEM system, which means it's probably of very low quality, and won't put out anything above what it's rated for. Sorry... looks like you'll be replacing it... consider buying an Antec Earthwatts or a similar high-quality unit.

Thanks for the feedback, I'm not quite sure what to look for when buying a new PSU so I was wondering if this would be an okay one for me to use because I kinda have a low budget once I get a new graphics card.

Buying a psu and the 650 ti would be a lot of money all together, I suggest buying the EVGA GTX 750 Ti Superclocked or just the regular (Superclocked is better), this way you wont have to upgrade your psu, before you do that what is your current PSU Ampage (should be on the label of psu) and whats your current CPU specs?

Sorry I had to actually check the label on the power supply itself...
I have no idea what these numbers really mean but I'll just copy it down here:

AC Input
100-127V ~ 8A 50-60Hz
200-240V ~ 4A 50-60Hz

DC Output
+3.3V ------- 12.0A
+5.06V ------- 13.0A
+12Va ------- 12.0A
+12Vb ------- 16.0A
+5Vsb ------- 2.0A

I don't really have a good feeling that the 750 Ti will be able to run on this psu :(

Your cpu takes up 65W TDP, meaning at the absolute most with fans, motherboard and everything running your whole system is taking 125W, leaving more than enough headroom. Just make sure you buy the EVGA 750 Ti or EVGA 750 Ti superclocked or gtx 750 ti's that don't require a 6 pin connector as you probably don't have that. Also your PCI E X16 (Gen 2.0) will have no problem powering a GPU with max TDP being 75W peak. If you get the 750 Ti your total system power should be around 200W which will surely work fine. If you don't believe me here's a video of PcPerspective running 350w, 300w, and 250W psu's on the 750 ti:

Thank you very much! After watching that video you posted, that surely made me more confident about choosing the nVidia GTX 750 Ti for my next GPU! :D
