I'm working on setting up a PC for a friend and running into some challenges. The motherboard is an Asus M5A97 R2.0. I have two powerful GPUs: one is an Asus R9270 with 2x DDR5, and the other is a Radeon Sapphire HD5770 with 1x DDR5. Both are six-pin PCIe powered. The power supply provides 620 watts. When both GPUs are installed, the motherboard fails to turn on. I have a smaller GPU that gets powered differently—this one is a Core i7 R5 220 with 2x DDR3—and it works fine. I've tried connecting it directly to the PCIe slot and using the other GPU through its six-pin connector to test if the PSU was the issue, but it still worked. I updated the BIOS to the latest version, but the problem persists. Any advice would be greatly appreciated.

This board is quite outdated, but generally it should function with modern GPUs. If you've checked all PCIe x16 ports and confirmed compatibility elsewhere, it's likely the issue is elsewhere. Would testing with another power supply help?

Check if the board requires a BIOS update or if a 32-bit system with 64 cards is the problem.

I've used a 500-watt power supply and the problem still happens. I suspect it's related to the motherboard or BIOS since it works fine with an older DDR2 board. The BIOS is also up to date.

Occasionally it occurs. Infrequently on Asus boards, yet we don't know. The cards require power from the PSU, the motherboard, and this one might not supply enough for your larger card.

My system ran flawlessly with the GT 710, while the 5700XT I bought failed to display anything. The PC handled everything smoothly, so I had to replace the CPU and now everything is working properly.

Thought like that is that the pcie slot doesn't provide all the power needed buy those two gpu even tho they are plugged they still need the pcie power and if they want let's say 75W and that the slot can only provide 50W that might be the problem. Just throwing idea there tho. Maybe you could find the mount of power the slot can provide on that board and see if that idea is on the right track or just bogus.
