My ATX 24-Pin connector is burned after I run it with dual Asus Strix RX 570 OC.
I took weeks to find out the root cause, and here is the result:
Clearly, ATX 24-Pin is the bottleneck.
144W is not enough to support the whole potential power consumption from PCI-E slots.
Motherboard manufacturers don't tell you that.
There is one question unanswered: How much power graphic card drawn from PCI-E slot?
Thanks tom's HARDWARE, they test it! Here are some data from www.tomshardware.com
Power drawn from +12V PEG on Torture:

Other information:
Motherboard usually uses over-spec power plugs, and this is why power connector always got burned first.

Other information:
Motherboard usually uses over-spec power plugs, and this is why power connector always got burned first.
Conclusion:
- Watch out ATX 24-PIN, 12V@144W is its safe limit.
- Choose graphic card carefully if you want to use SLI/CrossFire.
- Motherboard should provide additional 12V plug for the need from PCI-E slots, but most of them don't.
