I just bought Asus rog strix 1070 OC 8G .. it requires 8pin Power connector.. but my PSU don’t have 8pin or 6pin.
Can i use Dual Molex to 8-pin converter to power my 1070?
Ps: My PSU is 600W 80+ bronze

Your psu does appear to have a 6+2 PCIE connector, use that. If you have some weird model that doesn't have it for some reason do not use adapters in this way.

Also your setup... I like it. With a 1070 it should be lots of fun!

Power supplies are not created equal. Every psu vendor or manufacturer on the planet knows what a pcie 6+2 is for and has known for as long as gpus have required power plugs.

So the lack of pcie says 2 things. First, that the 12v rail that is the source of pcie power cannot support the 180w possible from a 6+2pin connection and Secondly the vendor/manufacturer absolutely knows this so purposely did not include that option.

That FSP is a closer to 20 year old group regulated design from back when pc's used a Lot more 3.3v and 5v DC and very little 12v. It's in reality closer to a 200w psu by modern standards than the 600w printed on the label.

Do not try and use molex-pcie adapters, the chances of the psu going up in smoke are very high with that kind of power draw on a rail that barely meets the minimums to run a non-powered gpu.

It's like having a little 4cyl car with a top speed of 70mph, and figuring you can get it to go 100mph by driving down a mountain road. Forgetting that the brakes on the car were never intended to try and stop that car from that speed.

Any halfway decent 550w (there are No decent 500/600w) psu will do. Look for psus with at least a 6+2pin And a 6pin pcie.

Back then, gpu didn’t require that kind of power thats why they didn’t include the pcie connectors in old psus .. what if i add a 8 pin cable to psu from any electrician or hardware shop?

Thanks man! I just looked in to my PSU, and hell yeah it does have 6+2 pin connector.. last time i had r9 270x which also required 6pin, so i bought molex to 6pin, but when i opened my system, 6pin was already there, so it was long time ago, i have forgotten that if i used molex or my psu had it. On your saying i again checked my psu, and remembered that my psu has 6+2pin connector ..
Thanks again!
