ROG STRIX X299-e gaming II, shuts down I play AAA games

[Ylueria]

Hello,

I am having an issue with the unit I just build, whenever I try to play AAA games the pc shuts down right away and a red light will turn on the motherboard(left side of the CPU and fan)

I am lost and I don't know what to do. 

Can someone guide me?

here are my specs:

CPU:

Intel Core i9-10900X Desktop Processor 10 Cores up to 4.7GHz Unlocked LGA2066 X299 Series 165W (BX8069510900X)

MSI Gaming GeForce RTX 3060 12GB 15 Gbps GDRR6 192-Bit

x2 Timetec 8GB DDR4 3200MHz (or 2933MHz or 2666MHz) PC4-25600 CL22 1.2V Non-ECC Unbuffered  

Thermalright Frozen Notte 240 WHITE ARGB Water Cooling CPU Cooler

MMOMENT NVMe M.2 2280 PCIe Gen 3x4

GAMDIAS ATHENA M6 LITE White Gaming pc case, Mid-Tower ATX Case

EDIT** @achugh Here is my PSU  Corsair RM750e (2023) Fully Modular Low-, I also tried using a 850 watts psu I had the same issue with it, should I try 1000 watts? and yes both are connected

Hi @Ylueria are you talking about PLED5300 getting turned on? This is the LED between DIMM and CPU on the left side. See below the layout from your manual.

Typically, what you are observing is caused by motherboard not having enough power. You did not mention your PSU unit. Can you edit your POST and fix that? Also did you connect BOTH the EATX12V 8 PIN connectors? I am referring to #4 item in this layout.

I strongly suspect that your build is getting starved which means you PSU is able to provide power when peak demand is requested causing you an issue.
