Hey guys, I recently purchased a EVGA Geforce GTX 750 TI SuperClocked for my Alienware rig, prior to putting it in my machine I wanted to come here to check; I have a 240 Watt external brick Power Supply, I understand that it is recommended that I upgrade to a 330 Before I put it into my computer. I would like to know what would happen if I did not upgrade the PSU? Will it bottleneck my computer, or will it still be playable?
