aqirys

A friend of mine wich I sold an Aqirys Pulsar LS 650w 80+Bronze want s to put it in an old pc with an i7 4790k a 1050ti gpu and 32gb of ram, but on his motherboard(Idk the model, but old ish) the cpu socket only has 4 pins, and the Aqirys powersupply has 8 pins wich can be divided in two, each...

I will soon get a used 1070ti or a 1080, I was wondering if the cables of an Aqirys pulsar 650w 80 plus bronze work with those gpus?
