The powerful DarkFlash 1250 W PSU for gaming PCs and workstations offers ATX 3.1, PCIe 5.1 with 12V-2x6 up to 600 W, 80 PLUS Gold efficiency up to 93%, fully modular cabling, and quiet cooling with a 120 mm HDB fan. A stable single-rail +12 V design, high-quality Japanese 105 °C capacitors, and comprehensive protections ensure reliability even under heavy load.

The DarkFlash PMT1250 is a compact and highly efficient power supply for modern builds. Support for ATX 3.1 and the PCIe 5.1 (12V-2x6) connector with 600 W output prepares your PC for the latest graphics cards. The 80 PLUS Gold certification with up to 93% efficiency reduces losses and temperatures, while a strong single +12 V rail with DC-DC converters guarantees stable voltage even during sudden spikes.

Inside you’ll find active PFC (up to 99%), Japanese 105 °C electrolytic capacitors, efficient heatsinks, and EMI filtering for clean, stable output. A 120 mm hydro-dynamic bearing fan with intelligent control keeps noise and temperatures low. Fully modular, flat cables improve airflow and simplify cable management—all in a chassis measuring 140 × 150 × 86 mm, compatible with most cases.

Safety is provided by seven-stage protection: OVP, OCP, OPP, SCP, OTP, UVP, NLP, complemented by Surge 4K against overvoltage. The PSU is ideal for long-term loads, demanding gaming, multi-GPU work, and rendering.

  • ATX 3.1 + PCIe 5.1 – ready for the latest GPUs with 12V-2x6 (600 W)
  • 80 PLUS Gold – efficiency up to 93%, lower heat and power draw
  • +12 V single-rail & DC-DC – stability and precise voltage regulation
  • Quiet 120 mm HDB fan – intelligent speed control
  • Fully modular cabling – clean build and better airflow
  • Wide protection + Surge 4K – safety for the PSU and components
