SEASONIC FOCUS GX-750 Restarts

850W+ ATX 3.0 Power Supply Unit

Modern high-performance GPUs generate nanosecond power excursions that exceed the 750W threshold of the current unit's protection logic. Upgrading to a higher-capacity unit with ATX 3.0/3.1 certification provides the necessary headroom and revised transient response timing to prevent the supervisory IC from triggering a hard reset during peak demand.

Individual 8-Pin PCIe Power Cables

Using a single 'pigtail' cable to power high-draw GPUs causes excessive current density and voltage drop across the 18AWG wiring. Utilizing two or three discrete, non-shared cables from the PSU to the GPU reduces impedance and minimizes the likelihood of the PSU sensing a voltage sag that would otherwise trip the Under Voltage Protection (UVP).

Power Cord / IEC C13 Cable

A loose or high-resistance connection at the AC inlet can cause intermittent arcing or voltage drops when the PSU draws high current from the wall. This interruption in the primary side capacitance charging can lead to a loss of the DC hold-up time, resulting in a system reboot.
