The system will boot normally and runs but the graphics is very slow. I was told 19.04 has drivers for this but maybe not. The smi utility says it can’t communicate with the gfx card. Taking into account the above mentioned stuff do you still confirm it is proper to use 2x6pin to 8pin adapter? can my adapter of my external pc .. would be good to provide power to my GPU , please help me out, I can provide more info, my gut feeling says yes and I cant test at the moment as my graphics card is still in transit.

But doing this kind of stuff is not recommended because it can limit your graphics performance & also affect the lifespan of the graphics card.

When choosing an 8-pin connector, consider your computer’s workload and select an adapter of good quality. FAQs Can you use a 4-pin on an 8-pin motherboard? I don’t know exactly how much it delivers on PBC 8 pin header. the 12V says 18amp about 8 places. So its either 18 amp or 18 x 2. I’m guessing its 18amp = 216 watts + 75 watts on the PCix slot = 291 watts max TDP for a graphics card. connectors have 2 additional ground wires. The extra ground wires are there only to tell the video card that the connector is different.

My PSU is a 600Watts solytech sl-8600eps, its old but it never failed me and i dont want to buy another PSU, it ony has 2 x 6 Pin Pcie, it does not have a 8 pin connector, my current GPU is the Asus Strix Gtx 970 (145 Watts Tdp) and it has a single 8 pin connection so i have been using for 3 years a 2 Molex to 8 Pin Adapter and i never had an issue, but now i am thinking upgrading to a RTX 2060 (160 Watts) with one 8 Pin Connection but i read that this GPU can pull at Max a Peak of 193 Watts some times and i read also that Molex adapters can Melt under Heavy Loads, so IT would be better to maintain the dual molex adpater? or to get a Single 6 Pin to 8 Pin Adapter? because i know that the 6 Pin PCie Cable from the PSU can carry more than the 75 Watts that most people think it can only carry, what i Dont Now is that the 6 Pin to 8 Pin Adapter can carry more than 75 watts? If true i’m strugling with the 6pin, because if 8pin cable can get “just” 150W and i get the adaptarer, the cable from power supply will be recieving more Watts than it can.?? Nothing can happen as most GPUs can’t boot without noticing a full 8-pin connector. Pulling many watts with two pins less isn’t safe, especially under full load. If the card, by any chance, boots, it may be unstable as it doesn’t receive the power it needs. Conclusion I know one guy that got twin 1080s working but it was not stable running both off the 8 pin PS pcb header. That would be 180 + 180 = 360 watt. He got it stable by running the other off a header meant for hard drives and accessories. A 8 pin connector tells the video card that it may take up to 150 watts through that connector. Power supply manufacturers are supposed to use at least AWG18 rated cables and you'd have 50 watts per pair of wires or around 4A per pair, which is around 40-50% of the maximum recommended current for the wires and connectors. So there's still some room for safety and everything.

First, let me say that you are amazing. You’re very kind to help so may people for so long. Your article here is very informative and has excellent information.
