CABLE SPLITTING

[MyGetthoRig]

hi...i wanted to have a crossfire config for my HD7870...but my silverstone power supply only provides 2 x 8pin connector...question is, can i use a 8-pin splitter? so that from (2 x 8pin) + splitter = (2 x 8pin)(2 x 8pin)...hope I conveyed it correctly...will there be any performance issues or psu issues if i use that method?

 

Thanks,

A single 8 pin provides 150 watts, you want to stretch that over double the connectors to make a 150 watt pinout provide 300 watts? That's asking for trouble.

 

The rule of thumb is that if your PSU doesn't have enough connectors for the job, it's just inadequate and you should consider a new one.

 

Also, what is the specific reason you want to go for dual GPU?

There are better ways to get good performance, an R9 280 or 280X isn't that expensive on the used market and would yield a decent performance bump. Consider even a 290X if possible

 

Also compare them to RX 470 and 570 prices

ahh i see now...I only know nvidia line up and never amd...so im guessing its better to upgrade to R9 rather than having dual gpu which draws tons of power...thanks man..i appriciate it..
