So I was selling a gtx 1070 ftw which consumes 210 watts. I went to the guy so he could try it, and we hooked the gpu to a 550w fujitsu atx psu which had If I remember correctly 2x8 pin+ 1x6+2 pin. I was worried cuz I thought it would blast, but to my surprise, it handled quite well, we could run msi kombustor, and no problems. So I was thinking whether it'd be a good idea to ditch buying fancy expensive branded power supplies (i have cx450), and get one of these fujitsu ones for 10 dollars or under, and run high tdp hardware just as fine? Thanks
