750 W ATX power supply for PC builds

The GIGABYTE GP-P750GM delivers 750 W from a single +12 V rail rated at 61 A. It follows the ATX 12V v2.31 design guide and carries 80 PLUS Gold certification for 90 % typical-load efficiency. Full modular cabling lets you connect only the leads your system needs.

Thermals noise and power draw

A 120 mm hydraulic-bearing fan spins under smart control to balance airflow and acoustics. Active power factor correction smooths input current across the 100-240 V, 50/60 Hz range. Hold-up time is 16 ms minimum and the power-good signal arrives within 100-500 ms after switch-on.

Build quality and daily connectivity

Main Japanese capacitors and a full protection suite — OVP, OPP, SCP, UVP, OCP, OTP — underpin the 100000-hour MTBF rating. The 140 mm chassis fits tight spaces while supplying 20+4-pin ATX, two EPS 4+4-pin, four PCIe 6+2-pin, eight SATA and three peripheral connectors.

Questions about this item

Will this 750 W unit fit in a compact case with a 140 mm PSU clearance limit?

The power supply is exactly 140 mm long so it will fit only if the case allows the full 140 mm depth without cable interference.

Can the four 6+2 pin PCIe connectors run a graphics card that needs two 8-pin and one 6-pin plug?

Yes, each 6+2 pin cable can serve as either an 8-pin or 6-pin connector, giving enough plugs for that configuration.

What protections are built in to guard the system against power faults?

The unit includes over-voltage, over-power, short-circuit, under-voltage, over-current and over-temperature protection circuits.
