So i got this casper fsp250-50hmn psu and a Radeon HD 8350, im going to upgrade it in the coming months i already planned what psu to buy etc. there's no prob with that, its just that im saving for the PSU right now and i was wondering what would happen if i got the 750 Ti first? would it run games? I mean i know it requires at least 300 watt, its just im curious, it won't give its full performance? Will it work at all?
