750 W ATX 3.1 power supply

The ASRock PRO-750G is a 750 W ATX 3.1 compatible power supply built for modern desktop builds. It carries 80 PLUS Gold certification and a full protection suite including OCP, SCP, OVP, UVP, OTP and OPP. A single 120 mm fan handles cooling inside a 140 mm deep chassis.

Value-focused builders and compact cases

This unit suits builders who want ATX 3.1 readiness and a native 12V-2x6 connector without paying for higher wattages. Systems that demand more than 750 W or need multiple 12V-2x6 cables should look at larger models in the same series.

Native 12V-2x6 connector rated for 450 W

The decisive specification is the single PCIe 5.1 12V-2x6 connector rated at 450 W, which determines whether a modern GPU can be powered without adapters. Only one such connector is provided, so dual-GPU setups or cards requiring two native cables cannot use this unit directly.

Questions about this item

How can I confirm the 120 mm fan is running quietly after installing the PRO-750G?

Listen for low airflow noise at idle; the 120 mm fan is designed for quiet operation and should spin without audible rattle once the system powers on.

Which cables come attached to the PRO-750G and which must I source separately?

The unit includes a 24-pin motherboard cable, one 4+4-pin CPU cable, one 12+4-pin PCIe 5.1 cable, two 6+2-pin PCIe cables, two 4-pin peripheral cables and four SATA cables; no additional cables are required for a standard build.

Should I choose the 750 W PRO-750G or the 650 W or 850 W models for a system drawing up to 450 W on the 12V-2x6 connector?

The 750 W model covers a 450 W 12V-2x6 load with headroom; select 650 W only for lower-power builds and 850 W for multi-GPU or future upgrades.
