GIGABYTE UD1300GM PG5 Gold 1300 Watt Fully Modular SMPS

The GIGABYTE UD1300GM PG5 is a 1300-watt fully modular power supply built around the Intel ATX 3.0 standard and designed to handle the demanding transient power requirements of modern high-end PC builds. Carrying an 80 Plus Gold efficiency certification, it delivers reliable, clean power across a wide range of loads while keeping energy waste to a minimum. At the heart of the UD1300GM PG5 is full compatibility with PCIe Generation 5.0 graphics cards. The unit ships with a native 16-pin (12VHPWR) cable capable of delivering up to 600 watts to a single GPU, and the PSU itself can sustain up to 3× GPU power excursions as defined by the ATX 3.0 specification. This makes it a strong pairing for flagship discrete graphics cards that draw large, short-duration power spikes during heavy rendering or gaming workloads. GIGABYTE's Ultra Durable design philosophy informs every major component choice. The primary filter capacitors are sourced from Japanese manufacturers, a deliberate selection intended to extend the operational lifespan of the unit and maintain output stability over years of use. The thermal solution has been upgraded relative to standard designs, with an enlarged heatsink and optimised internal airflow routing to improve heat dissipation and reduce component stress. A 140 mm double-ball-bearing fan manages internal temperatures dynamically. Fan speed scales with detected system load, and the unit enters a near-silent semi-passive mode — fan stops completely — when the system is idle or running below approximately 20% load. Double-ball-bearing construction is specified for extended service life compared with sleeve-bearing alternatives. Six independent hardware protection circuits guard the connected system: Over Voltage Protection (OVP), Over Power Protection (OPP), Short Circuit Protection (SCP), Under Voltage Protection (UVP), Over Current Protection (OCP), and Over Temperature Protection (OTP). The fully modular cable design means only the cables you actually use are connected, reducing clutter and improving airflow inside the chassis.
