6 pin flex psu to dual 6+2 gpu connector wiring

[Pvt_mango]

Hey guys first time posting here, im building a mini sff pc and am using a flex PSU I got of AliExpress, the PSU has a 6 pin pcie connector which I need to wire out to my GPU's (7800xt) two 6+2 connectors, now I was able to find a 6 pin to 6+2 pin wiring diagram, the question I had was is it okay to just parallel the other 6+2 connector with the first 6+2 connector?

Is your flex psu powerful enough ? (700W is recommended)

What flex psu is that?

Flex psu from aliexpress is like instant WARNING DO NOT USE blaring sirens. As in a bad psu will just flat out kill a pc no sweat with ease.

 

Considering this thing is obviously missing the connectors its already telling its not going to do the job.

 

Keep in mind you are asking 300w of power from a 6 pin which is specced for 75w of power. i dont need to tell you how bad of an idea that is I hope.
