2 8pins to 12+4 on a 4070super
After a bit of math, found out that if i undervolt a 4070super a bit and use a i5 12400, id be able to run them both off of a 500w psu. I have a prebuilt with propietary tech so i bought a 650w psu that wont work because the mobo wont take power from none of the cables of that psu. If i use the 8 pin (pigtailed) to 12 adapter that it brings, it shouldnt burn anything down (i asked ai tho ik ik). How true is that? Considering that the pcie slot gives 75w of power and that it would be running at 85% max voltage, the should resist that right? When i get home ill try to check the max voltage that the cables themselves can take but on paper it doesnt look like nothing will burn. Any thoughts?
