Power for ATX 3.1 and PCIe 5.1 builds

This 750 W unit meets the latest ATX 3.1 and PCIe 5.1 specifications, making it ready for modern graphics cards and processors. It handles power excursions up to 220 % and responds quickly to sudden load spikes. The 80 PLUS Gold and Cybenetics Gold certifications confirm high efficiency across typical workloads.

Full modular design with native 12V-2x6 cable

All cables detach completely, so only the required leads stay inside the case. A native 16-pin 12V-2x6 connector includes a dual-colour indicator that shows when the plug is fully seated, and an NTC sensor monitors connector temperature for added protection. The 135 mm striped axial FDB fan runs under iCool intelligent control, staying off at low to medium loads to keep noise down.

Check clearance and connector count before ordering

The power supply measures 175 mm in length, so verify that your chassis can accommodate it. Ensure your motherboard uses a 24-pin main connector and that the two 8-pin EPS cables suit your CPU power sockets. Confirm the three 6+2-pin PCIe leads and nine SATA power plugs match the drives and peripherals in your system.

Questions about this item

Will the 175 mm length fit in my mid-tower case?

The unit is 175 mm long. Measure the clearance from the rear panel to the nearest drive cage or cable bend in your case; if that space is 175 mm or more it will fit.

Can I power a modern graphics card with the native 12V-2x6 connector?

Yes. The PSU includes a 16-pin 12V-2x6 cable rated for PCIe 5.1 cards and the dual-colour design helps confirm a full seat.

What does the +5V Boost switch actually do?

When enabled it raises the +5 V rail to about 5.15 V to compensate for voltage drop on heavily loaded cables; leave it off if your system shows no drop.
