Took a photo at the PSU here. It is 400W, which I think should be enough, especially when the CPU connection only need 4 pin
You don’t have enough power supply.

It really seems like replacing that with a higher rated name brand psu will resolve your problem. You’re running up against the maximum power the pcie slot is rated to deliver. Claimed wattage only tells part of the story. All that power for the card has to come through the 24 pin connector along with everything else.
If you wanna prove me wrong plug the motherboard/cpu/gpu into someone else’s higher rated power supply and show that it has the same behavior.
If there’s a computer shop near you they’ll probably do this test in front of you with one of their power supplies for a couple of bucks. If there’s a gamer friend they’ll do it for free to help you figure out the problem.
Look into Nvidia MATS/MODS if you want to test the card and its memory. It’s Nvidia’s own internal diagnostic software.
Look up the beep codes for your motherboard in the manual (find on their website) to confirm what the beeps mean. (Good to have downloaded/bookmarked anyway)
Next/first, with the computer turned off at the PSU (but still plugged in) try removing and re-slotting the GPU (there may be a button/leaver to release it on the motherboard. There may also be a screw holding it into the case on the inside at the back). If it only sometimes doesn't work, that indicates it's probably just a bad connection.
I’ve a similar board. Long-short-short-short means no graphics adapter detected, and then that pause with one short beep I think means no keyboard detected.
Edit: ASUS have stopped putting the beep codes in their manuals for some reason so I don’t know where one is expected to find this information out. It was in my manual but that’s a much older model.
Likely an issue with the card, if you can find another dGPU or use your CPU's on-board video you can isolate as to whether it is an issue with that card specifically.
Likely the card has bad memory or a corrupted BIOS.
If it works sometimes and others not at all, it's probably a connection issue. Bad memory or bios would either fail every time or cause corrupted output I think?
