Where does a GPU get it's power from PCIe or 6pin?

Hi,

I'm wondering where does the gpu get it's power from? Is it from the connection with the mobo or the 6 pin connector from PSU?

Usually from the PSU and maybe a little from mobo connection, but there are some models like 1050s that have only need the mobo connection. Also some gpus use 8 pins and combination of 8 and 6.

Most graphics cards receive power from cables connected to a psu, and if your gpu has a 6 pin, it’s going to need to be powered by the 6 pin.

The PCIe slot can provide up to 75 watts of power. For cards that need more than 75 watts, additional power connectors are required.

Depends. A low power GPU that uses less than 75W of power, can be powered only by the PCIe slot. More powerful cards will need supplementary power through the power connectors.
