I have 4 GPUs for mining:
ASUS RTX 3080 TUF OC 10G
Sapphire Vega 64 Limited Edition 8GB
2 x Gigabyte RX 580 8 GB
These 4 GPUs would be connected to a motherboard Gigabyte B460 HD3 that has 5 PCIe slots, using risers.

I have 2 PSUs available that I would like to use in the rig:
INTER-TECH Power Supply Great Wall M1200 (1250 W)
Corsair RM 750 W
The main question that bothers me is how I can connect both PSUs to power the rig since one is not enough and the motherboard only has a 1x 24 pin slot, 1x CPU power slot, etc... Have you maybe used 2 PSUs similar to these above?

How would you do it? Thanks.

I have used these synchronizers.
It's called the Molex 24-pin ATX PSU Trigger Synchronizer.
You connect the first power supply to the motherboard, and connect the Molex connector from it to this synchronizer.
Plug the 24-pin of the second block into this synchronizer and both power supply blocks will turn on and off simultaneously.
