GIGABYTE UD1300GM PG5 1300W 80+ Gold ATX 3.0 Fully Modular Power Supply

The GIGABYTE UD1300GM PG5 is a 1300-watt fully modular power supply built to the Intel ATX 3.0 standard, making it a capable foundation for high-performance desktop builds that rely on the latest PCIe Gen 5.0 graphics cards. Its native 16-pin connector delivers up to 600 watts of clean, stable power directly to a compatible GPU, and the unit can sustain up to 3× GPU power excursion events — a critical requirement for modern graphics cards that spike sharply above their rated TDP during heavy workloads. As an ATX 3.0-compliant design, the UD1300GM PG5 also supports up to 200% total system power excursion and reaches 70% efficiency at low load, meeting Intel's Power Supply Design Guide (PSDG) timing requirements. The unit carries an 80 Plus Gold certification, indicating verified above-average conversion efficiency across standard load ranges, which translates to lower heat generation and reduced energy waste during extended gaming or rendering sessions. GIGABYTE's Ultra Durable build philosophy is reflected throughout the unit. The main filter capacitors are sourced from Japanese manufacturers, chosen for long-term reliability and stable output under sustained loads. Thermal management is handled by an enlarged heatsink with optimised internal airflow compared with a standard thermal solution, working in conjunction with a 140 mm double ball bearing fan. The fan operates silently at idle and below 20% load by stopping entirely, then spins up automatically as load increases — extending both acoustic comfort and fan service life. Six independent protection circuits guard the system at all times: Over Current Protection (OCP), Over Temperature Protection (OTP), Over Voltage Protection (OVP), Over Power Protection (OPP), Under Voltage Protection (UVP), and Short Circuit Protection (SCP). The fully modular cable design means only the cables required for a given build are connected, improving airflow inside the chassis and simplifying assembly.
