Is it okay if I do 2 sata power to 8 pin with my 6pin and 8pin GPU?

I have a 6pin power cable for my GPU and I need an 8pin. Will it be okay if I buy a adapter for 2 data cables to one 8 pin. Or could you suggest a PSU that would power at r9 390. I have a 750w PSU right now.

Where would i find this information? Sorry
 


It should be on the PSU's label.

From the info I could gather on the Alpine 750W PSU it has a +12V capacity of 38 Amps maximum. I have great doubts that it is 38 Amps continuous. More likely it is the useless peak rating.

Since the PSU only has one 75-Watt 6-pin PCI Express supplementary power connector it is an indication of just how weak of a power supply it really is.

Exactly as I said.

If you like a PSU that blows up then you've chosen one that will do exactly that.

Don't bother connecting an expensive graphics card to that PSU because the PSU won't survive.

What PSU and GPU would you recommend then for a budget around £260?
