RTX 3070 Power Connections
M_Pozzi
✭
Hi all, I am planning on buying an RTX 3070, most likely an EVGA or Asus variant, both of which all require 2 x 8pin to power. However, on my power supply, which is a PowerSpec 650watt semi modular, I only have one 8pin, and 3x6pin connections. The Power supply comes with a cable that has an 8pin on the PSU side, splitting to 2x(6+2pin) connections, filling both connectors on the GPU.
My question is if this single cable from one 8pin on the PSU will supply sufficent power to the GPU. I should also say I am running a Ryzen 7 3700x, so if there are any power concerns, I would love to know if an upgraded PSU is needed Thanks for all your help!

The GPU will need both 8pin power for it to work properly. The splitter you're mentioning 2x 6+2pin should work to supply GPU with the needed power.However, Nvidia does recommend a 750 Watt PSU for the 3070. It's possible that the 3070 may trip the power draw protection. If this happens it will turn off the system.Hope this info helps.
