PC crashes when gaming
I assembled my initial PC about a week ago. Everything proceeded without issues until two days after the first startup. My system froze during a WoW session and wouldn’t boot again afterward. I began investigating and found a Reddit post mentioning a similar issue—specifically, a 24-pin connector. I examined the cable and pressed the power button; it worked properly then. Later, after some adjustments, it would restart and turn on again.
A few days later, it happened once more, and it would power up briefly before crashing. Yesterday night it occurred again—after turning it on, it remained active for roughly 10 to 60 minutes before failing, totaling three crashes today. I’m now uncertain what’s causing this. I’ve confirmed the 24-pin connector is intact, properly connected, and everything seems fine.
This problem consistently appears during gaming sessions and under full GPU load. The system draws around 320 watts when it crashes, while my PSU provides 750 watts. What do you think is the main cause? Is it the power supply unit, the graphics card, the motherboard, or something else?
I have an older 1050 Ti processor available for testing, but I’d appreciate your insights first. I’m concerned about potentially damaging my components with these recurring crashes.
Thank you.
I believe your GPU is delivering too much power to the motherboard. The Ryzen 7 7800x3d is a 120W CPU, but your case is drawing 330W. Could you verify if your PC case causes shocks when touched? Also, inspect your 24-pin connector closely—check for any loose pins in the cable. For instance, applying pressure to detach a Molex cable might dislodge a pin.
AMD's software displays the power consumption of the motherboard and the board's power usage. 330W represents the maximum capacity of your GPU's mainboard. If the PSU provides more power, the board may reject it or suffer damage.
It could be various things, so make sure all power connections, ram, and gpu are correctly placed. Then I would attempt the 1050Ti; if that works, you're good. If not, you've likely narrowed it down.
