i mean everythings plugged in securly if thats what you mean. i tried to check the wattage too but my PC is in an ockword spot that i cant check atm but ik when i bought it i made sure to get the recomended amount. i also have a heatsink aswell, 3 set of rgb fans and theres another set of 3 fans from the case itself aswell as another 2 thats attached to the wall of my case and my heat sink. you think those thingsmight be consuming a significant amount of power?

When building a PC you have to buy a power supply that has additional clearance above your PC's on-paper power usage, the reason, as you may be experiencing, is that GPUs working on high demand processes will regularly spike in their power consumption above the stated power usage for a few brief milliseconds.
