What this PSU delivers

The darkFlash PMT750 is a fully modular ATX power supply rated at 750 W. It meets ATX 3.1 and PCIe 5.1 specifications and includes a native 12V-2x6 cable capable of 600 W for modern graphics cards. 80 PLUS Gold certification confirms efficiency above 90 % under typical loads. Japanese 105 °C capacitors and DC-to-DC conversion support stable voltage regulation.

Check your build before ordering

Verify that your case accepts a standard ATX unit and that you have space for the 135 mm FDB fan to exhaust freely. Ensure the motherboard uses a 24-pin ATX connector and an 8-pin or 4+4-pin CPU power connector. Confirm your GPU requires the 12V-2x6 connector or standard PCIe 8-pin plugs. The PSU operates on 100-240 V input at 50/60 Hz with a 10 A input current rating.

Build quality and daily implications

Full modularity lets you connect only the cables you need, reducing clutter and improving airflow in ATX or Micro-ATX chassis. The hydraulic bearing fan runs quietly while moving enough air for sustained loads. Protection circuits include OVP, OCP, OPP, SCP, OTP, UVP and NLP. A 5-year warranty period reflects the manufacturer’s confidence in the Japanese capacitors and overall construction.

Questions about this item

Will the native 12V-2x6 cable power an RTX 40-series card without an adapter?

Yes, the included 12V-2x6 cable delivers up to 600 W directly to compatible RTX 30 and 40 series graphics cards, so no adapter is needed.

Does the fully modular design help with cable routing in a compact ATX case?

Yes, you connect only the cables your build requires, reducing clutter and improving airflow inside standard ATX or Micro-ATX enclosures.

What protections guard the system against power anomalies?

The unit includes OVP, OCP, OPP, SCP, OTP, UVP and NLP circuits that shut down or limit output when voltage, current, temperature or power exceed safe limits.
