I must give juice to 4x 1080ti. I only have 2 of those 8 pin to 8 + 8 (6+2) per PSU. I have another rig 6x 1070 on a corsair PSU.

The rig I want to place the 4 1080ti is a EVGA PSU... Somehow the companies hate each other and even though the cables are same family, they won't fit.

Now my question is, if I cut or use sandpaper to modifiy the shoes that won't go into the PSU, would that be a big nono ?

I tried to find cable to buy separately, they seem to sell them only in complete set, which is almost $100.

You want to blow some shit up?
By all means modify the psu cables.

There are lots of power supplies that can handle running 4 1080 ti's, buy one.

Don't buy the most expensive mining cards, only to cheap out on the power supply.

You must have gotten me wrong. I have two separate PSU. I only lack on enough cables for them. 1080ti needs the 8 pin to 8 + 6 pin cable.

They make adapters for that....to turn an 8 pin into an 8 + (6+2)

look for 16 awg 18 awg is dangerous imo

This. And even then I'd be skeptical. 8-pins can deliver 150 watts (6 pin can do 75 watts) or 12.5 amps each so running twice that off of one cable is not a good idea.

There's a reason higher end PSUs give you more 8+6 ports and cables instead of simply giving you more 8+8 (or even 8+8+8+8) cables. I don't think I ever got a 8+8 pin cable with any PSU, only 8+6.

If you go down that route of splitting the 8-pin into 2, check the temperature of the cable all the way and get back to us, I'm curious.

What I do know for sure is that you should never interchange cables for different brand PSUs, they don't use the same standards even if the cables fit perfectly so you'll end up frying stuff.

I have evga 1000G. This PSU comes stock with 2 cables that work for 1080ti. I tdp around 70% on 1080ti already tested. They stay around 170Wx4 = ~680w plus the rest goes up to around 800w from the wall. This fits in the 80% push for the PSU which I think it's healthy.

I would have gone with evga 1600w PSU but they are ridiculously out of stock and didn't want to wait. As soon as the bigger psu comes in stock I am ordering it and I'll make another 4 or 5x 1070s rig with the 1000w PSU.
