GeForce GTX 1050 Ti 

Might be a little late but your power supply is crap. You don't want any GPU that needs an extra power cable plugged into it. The best you're gonna get without upgrading your PSU is a 1050TI.

I have Intel i5 4690 8 GB DDR3 Powerlogic Magnum 300 (300w pure power, 600w max poewr) With that GPU, can I run my pc using that PSU ?

75w ! I bet it is under 40w

I got a gtx 1060 and it's better than a gtx 1050ti. A gtx 1050 is about 200-280$ CAD A gtx 1060 is about 250-320$ CAD

300w should handle that but i would still be a bit cautious, depends on the build quality of the power supply really at that wattage.

Let me give you my specs intel core i7 2600k 8GB DDR3 GT 710

yep, bro! but forget 'bout the overcklocking gpu & cpu

Depends what other parts you have in your computer, but i would say no because even though it only uses 75w it could use even more at peak times when playing games and the computer might have errors if the RAM, cpu and everything else also draw a lot of power.

Is a 300w psu good enough to run it i'm going to get the card for christmas.

I got it. EVGA. i5-3470. Runs Skyrim SE at 1920x1080, Ultra settings with about 50 mods average 40-50 fps. I like it because it's tiny, low power, and runs really cool even when OC. I found an old Dell optiplex on ebay and just shoved this thing it. BAM! instant gaming pc. worth it.

someone got the card? some opinion?
