darkFlash DF-DG-750-BK 750 W ATX 3.1 power supply

ATX 3.1 power supply for modern GPUs

The darkFlash DF-DG-750-BK is a 750 W ATX 3.1 unit built for systems that need a native 12V-2x6 connection. It targets builders upgrading to graphics cards that draw up to 600 W through the new connector. The fully modular design keeps cable routing clean inside compact cases. It suits gaming rigs and workstations that require stable single-rail +12 V delivery.

Thermals noise and power draw

A 120 mm HDB fan handles cooling while the 80 PLUS Gold rating confirms over 90 % efficiency at typical loads. Active PFC rated at 98 % reduces waste heat and lowers mains current draw. The DC-to-DC topology with Half Bridge LLC and SRC circuits maintains tight voltage regulation under shifting loads. Seven protection circuits guard against over voltage, over load, over current, under voltage, short circuit, overheat and zero load conditions.

Accessories and software impact

The box includes a native 12V-2x6 cable rated for 600 W and six SATA connectors for storage drives. All cables use 18 AWG wire and an embossed finish for easier handling. Taiwanese electrolytic capacitors and EMI filters improve long-term signal quality. No software suite is bundled; configuration relies on the motherboard BIOS and operating system power management.
