PCIe 6pin, 8pin - differences

[PLSBX]

I will watch it later.

I think it's end of topic.
How can i mark it as solved?

My old Corsair HX620 has 6pins on the PSU and 8pins on PCIE cable. Modular cables I mean.

6pin can deliver the same as 8pin.

So 6pin to 8pin adapter is safe if PSU is good.

Please watch the video i posted: it explains why the problem is NOT whatever PSU you have.

pcie 6+2pin

PCI 6 Pin+2 = 8pin ( with the capability of disconnecting the +2 where its not needed)

pci 6 pin provide same power as 8 pin

the extra 2 pin up to 8 are useless ground from same common ground as the others

the 2nd 12V pin from 6 pin connector is not in use on vga PCB's so only two 12V provide power;these two provide min. 120 W not 75W

the three 12V pins from 8 pin connector ,all used on vga PCB, provide more than 150 W somewhere in range of min.220 W

as i see industry standards underrated all and is a big margin which allow the OC

before anyone ask how two 12V rail provide 120W:

molex 12V rail is rated 60W
2 molex to 8 pin adapter has two molex 12 V rail..... so 2*60W=120 W but 8 pin is rated 150W so it can draw 75w from each rail....

I suggest you get a proper PSU. So no 6 pin in a 8 pin. Not even an adapter

Good PSU should have good cables and pins right?

good PSU shouldnt require you to use a 6 to 8 pin adapter.

So i have good PSU? I only asked about differences.
