Apevia ATX-GX1000W Galaxy 1000W (No PCIe 5.0 & No Gen 5 12VHPWR Connector) 80+ Gold Certified Active PFC ATX Semi-Modular Gaming Power Supply

Bottom line: The Apevia ATX-GX1000W Galaxy 1000W: 1000W on a single +12V rail rated 83.3A, no split-rail juggling for multi-GPU builds; main trade-off: no 12VHPWR / 12V-2x6 connector, so RTX 40 and 50 series cards need adapters.

Pros & Cons

Pros

  • ✓ 1000W on a single +12V rail rated 83.3A, no split-rail juggling for multi-GPU builds
  • ✓ Semi-modular cabling lets you leave unused SATA and peripheral leads out of the case
  • ✓ Four 8-pin (6+2) PCIe leads plus dual P8 (4+4) EPS 12V for SLI or CrossFire setups
  • ✓ 135mm thermally controlled fan idles quiet and only ramps under real load

Cons

  • ✗ No 12VHPWR / 12V-2x6 connector, so RTX 40 and 50 series cards need adapters
  • ✗ Built to ATX 12V 2.3, not the ATX 3.x transient-spike spec modern GPUs assume
  • ✗ Semi-modular, not fully modular: the 24-pin and EPS cables stay permanently attached
  • ✗ Only four SATA connectors, tight for builds with several drives plus AIO and fans
