GIGABYTE UD850GM PG5 V2 Power Supply Unit- PCIe Gen 5.1, 80 PLUS Gold, Fully Modular Design, 120mm Fan, ATX 3.1 compatible, EU Plug

The GIGABYTE UD850GM PG5 V2 850W is a desktop power supply unit engineered to deliver stable, efficient power for high-performance PCs. It supports Intel ATX 3.1 and PCIe Gen 5.1 standards, carries an 80 PLUS Gold efficiency rating and features a fully modular cable design for simplified installation and cable management. The unit accepts 100–240 V AC input, provides a strong single +12V rail and uses 100% Japanese capacitors together with an optimized thermal solution to ensure long-term reliability.

Advantages

The PSU combines high efficiency (80 PLUS Gold) with a compact form factor and robust protections (OVP/OPP/SCP/UVP/OCP/OTP). A 120 mm smart hydraulic bearing fan and optimized cooling maintain appropriate temperatures under load while the fully modular layout reduces clutter inside the case. Built-in compatibility with modern standards (PCIe Gen 5.1, Intel ATX 3.1) makes it suitable for current and near-future hardware configurations.

Suitable for

• Gaming desktops with mid to high-end GPUs
• Workstations for content creation and editing
• Systems requiring clean cable management and compact PSU dimensions
• Upgrades where PCIe Gen 5.1 compatibility is desired

How to use

Install the PSU into a compatible ATX case following the motherboard and case manufacturer instructions. Connect the 20+4 pin ATX main connector to the motherboard and attach modular cables to your components (CPU, GPU, drives) as required. Ensure the AC input is within 100–240 V and switch on the system. Monitor fan operation and temperatures during initial use to confirm proper cooling and stable power delivery.

Recommendations

For optimal longevity and performance, keep airflow unobstructed in the case, use cables only as needed to maintain clearance, and pair the unit with components whose combined power draw stays comfortably below the 850 W rating to allow headroom for peaks.
