[SOLVED] PSU not giving enough power to motherboard?

[Walentyne10]

So im building a new pc, i installed and connected everything right, turn on pc motherboard lights up for a split second, my cpu fan is working, psu fan is working, gpu fan working, hdd working, but im not getting any display because the mobo just lights up quick and lights out, so my memoryes not giving any light either... So what would be problem here, weak or faulty psu, or something wrong with mobo? System spec > ryzen 5 5600g, aorus a520 elite, 1050ti, 2x8 gb ram kingston fury beast, PSU cooler master mwe white 500

The PSU is junk, but unlikely to be the problem here.

How did you update the BIOS of your motherboard to work with the 5600G and to what version? Only Ryzen 3000 CPUs are likely to work on this motherboard without flashing an updated BIOS, as can be seen on the board's compatibility list.

The mobo should support the 5000g series ( https://www.gigabyte.com/Motherboard/A520-AORUS-ELITE-rev-10#kf ) the pc even booted up normaly the firts time, and after that started this problem to occur

Did the 2 RAM modules come in a kit of two?

It does support the 5000G series. I asked what BIOS version you had. Out of the box support and support are two very different things with motherboards.

You literally did not mention in your post that the PC booted up normally the first time into Windows. If you limit the facts, you limit the solutions.
