SpecPicks Verdict

SpecPicks scored PCCOOLER KN750 750W ATX 3.1 Fully Modular Power Supply using a rating × review-volume × price-fit model applied to published specs and reviews across the power supplies & cables category. PCCOOLER's power supplies & cables lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Key Features

  • ATX 3.1 POWER FOR MODERN BUILDS: Built to the Intel ATX 3.1 standard with a PCIe 5.1 interface, this fully modular power supply is designed to manage changing system loads while keeping unused cables out of the build.
  • 80 PLUS GOLD EFFICIENCY: 80 PLUS Gold certification supports efficient power conversion under typical loads. A 100–240V full-range AC input makes the KN Series suitable for compatible mains environments; use the included regional power cord.
  • JAPANESE 105°C CAPACITORS: A Japanese bulk capacitor and 105°C-rated capacitors support stable long-term operation. The 120mm hydraulic-bearing fan uses thermal control to balance cooling and operating noise as load changes.
  • NATIVE 12V-2X6 GPU CONNECTION: The included 12V-2x6 cable provides a direct PSU-to-GPU connection for compatible graphics cards. Insert both ends fully, keep the plug seated, and avoid tight bends near the connector.
  • CHECK THE INCLUDED CABLES BEFORE ORDERING: Includes one 24-pin motherboard cable, two CPU cables, 2 PCIe 6+2-pin cables, 2 SATA cable sets, one 12V-2x6 cable, and the AC power cord. Use only the modular cables supplied with this PSU.
