Soooo, I have this budget pc that I want to use for 1 more year and I would like to buy the rx 460. I have an i5 2400, 6gb ram, a simple motherboard and momently a gt 740 (gt 740 hardly can run games at good settings so I really need a better one). The problem is: my power suplly has 300w. I don't have enough money for rx 460 and a better power supply. So I'm wondering if I could run the rx 460 on a 300 watt power supply. Anybody has an answer for me (hopefully a good one ;p)?
