Fonte de alimentação GIGABYTE UD750GM PG5 750 W 20+4 Pin ATX ATX preto

The GIGABYTE UD750GM PG5 750 W is a fully modular ATX power supply designed for desktop PCs. It delivers a total output of 750 W on the +12V rail, meets Intel ATX 3.0 power timing requirements, and carries 80 PLUS Gold certification for high efficiency. The unit includes a native 16-pin (+12VHPWR) cable that supplies up to 450 W to PCIe Gen 5.0 graphics cards and a selection of modular flat black cables for flexible cable management. A 120 mm smart hydraulic bearing fan and an enlarged heatsink provide active cooling while maintaining compact dimensions suitable for many chassis.

Advantages

The PSU supports PCIe Gen 5.0 graphics cards with a native 16-pin connector capable of delivering up to 450 W and is compliant with Intel ATX 3.0 power excursion and timing standards. Internal components include high-quality Japanese main capacitors, an enlarged heatsink for improved thermal performance, and a 120 mm smart hydraulic bearing fan with semi-passive operation at low load. Multiple protection circuits (OCP, OTP, OVP, OPP, UVP, SCP) and safety certifications ensure stable and protected system operation. The fully modular flat-cable design reduces clutter and improves chassis airflow.

Suitable for

• Gaming PCs with high-power PCIe Gen 5.0 graphics cards
• Workstations requiring stable 12V power delivery up to 750 W
• Compact ATX builds where a shorter 140 mm PSU improves compatibility
• Systems that benefit from modular cables and improved airflow

How to use

Install the UD750GM PG5 into a compatible ATX chassis and connect the 20+4 pin motherboard connector along with required modular cables for CPU, GPU and drives. Use the supplied native 16-pin (+12VHPWR) cable to power PCIe Gen 5.0 graphics cards that require up to 450 W; ensure the cable is fully seated into both the PSU and GPU connectors. Verify connections for all protection-enabled rails and route modular flat cables to optimize airflow. Connect the AC mains input within the specified 100–240 V range and power on the system to allow the fan to operate automatically according to load.

Recommendations

For reliable operation, match the PSU capacity to the total system power draw with some headroom for peak loads. Use the native 16-pin cable only with GPUs that support the +12VHPWR specification and ensure proper seating. Maintain clear airflow around the PSU intake and periodically check cables and connectors for dust or looseness to preserve efficiency and longevity.
