TUF Gaming 750 W ATX 3.0 PSU

This fully modular ATX 3.0 compatible power supply delivers 750 W of continuous power for modern desktop builds. It includes a 16-pin PCIe Gen 5 cable rated for 600 W alongside three 8-pin PCIe cables, two CPU 4+4-pin cables, five SATA connectors and four peripheral connectors. Military-grade capacitors and chokes, a protective PCB coating and dual ball-bearing fan design target long-term reliability under heavy loads.

Sustained-load behaviour

The 80 Plus Gold certification reflects high efficiency across typical load ranges, reducing waste heat during extended gaming or rendering sessions. Axial-tech fan design with a smaller hub and longer blades increases downward air pressure while the dual ball bearings are rated for up to twice the lifespan of sleeve-bearing alternatives. Full protection suite covering OPP, OVP, UVP, SCP, OCP and OTP activates automatically if voltage or temperature limits are exceeded.

Pre-installation checks for your build

Verify that your case can accommodate a 150 mm deep unit and that cable routing space exists for the 610 mm motherboard, 650 mm CPU and 675 mm PCIe cables. Confirm your graphics card requires either the 16-pin 12VHPWR connector or up to three 8-pin PCIe connectors, and ensure the motherboard accepts one 24-pin and two 8-pin CPU power inputs. Builders needing more than five SATA power ports or a higher total wattage should consider a different capacity.
