Gigabyte UD1000GM PG5 V2 Gold 1000 Watt ATX 3.1 Fully Modular Smps

The GIGABYTE UD1000GM PG5 V2 is a 1000-watt fully modular power supply built around the ATX 3.1 standard, making it a forward-compatible choice for high-end desktop builds centred on current and next-generation graphics cards. Its native 16-pin cable supports up to 600 W for PCIe Gen 5.1 graphics cards, and the unit is specified to handle up to three GPU and two system power excursions — the transient load headroom demanded by the ATX 3.1 specification — while maintaining 70% efficiency at low loads. All electrolytic capacitors are sourced from Japanese manufacturers, a supply-chain decision that contributes directly to voltage stability over the unit's rated service life. The 120 mm hydraulic-bearing (HYB) fan adjusts its speed in response to system load, spinning down to near-silence when the build is idle or drawing less than 20% of rated capacity. This semi-passive behaviour reduces acoustic output during everyday desktop tasks without compromising cooling headroom under sustained load. Power delivery is handled through a single +12 V rail rated at 83.3 A, simplifying cable routing for multi-GPU or high-TDP CPU configurations and eliminating the current-sharing complexity introduced by split-rail designs. The fully modular cable system means only required cables are installed, reducing cable bulk inside the chassis and supporting better airflow to other components. The unit measures just 140 mm in depth, which improves compatibility with compact mid-tower and micro-ATX chassis. Eight integrated protection mechanisms — over-voltage (OVP), over-power (OPP), short-circuit (SCP), under-voltage (UVP), over-current (OCP), over-temperature (OTP), no-load operation (NLO), and surge/inrush protection (SIP) — guard connected hardware against common power anomalies. The unit carries 80 PLUS Gold certification, indicating at least 90% efficiency at 50% load, and also holds Cybenetics Platinum efficiency rating independently measured at typical AC line conditions.
