Predator Orion 3000 PSU Upgrade Fail - How do I solve this problem?

Hello Guys

I recently got a selfmade computer based on a Predator Orion 3000. It ran well, but the GTX980 in it wasnt going to cut it for the future. So I got myself a RTX 2080 TI and thought I'd upgrade the PSU as well since 500W will be a little on the low side. Unfortunately I was not aware of this new ATX12VO thing and bought a Corsair RM750x PSU, which obviously cannot power the motherboard.

So now I either power my RTX 2080 TI with the 500W stock PSU from the Predator - but I am missing two pins on the PCIe output cable(there are only 14 from PSU but 16 on the RTX 2080 TI). So that does not seem to work. (?)

The other solution seems to be the Corsair ATX12VO adapter cable to transform the power for the motherboard. BUT, the board in the Predator has 3 power connectors: 1x6pin ATX1, 2x4pin ATX2&3. Meanwhile the Corsair adapter has a 10pin plug on the board side. Again, I am missing pins.


So question to you guys: What am I missing here? (apart from the pins, huehue..)
I am really confused and a little bit desperate, and every bit of help is highly appreciated.

Thanks in advance,
