XPG Corereactor II 1000W ATX 3.0

This fully modular power supply delivers 1000 W and complies with Intel ATX 12V v3.0 and PCIe 5.0 specifications. It includes a native 12VHPWR 12+4 pin connector plus additional PCIe 6+2 pin cables for modern graphics cards. The unit is built with 100% Japanese 105°C capacitors and a single +12V rail.

Sustained load behaviour at 1000 W

Gold certification from both 80 PLUS and Cybenetics confirms high efficiency across typical load ranges. Active PFC rated at 0.99 and a 135 mm fan maintain stable output during extended operation. Mean time between failures is rated at 100,000 hours at 25°C. Eight industrial protections guard against voltage and current anomalies.

ATX 3.0 and PCIe 5.0 interface limits

The 12VHPWR connector supports the power-excursion requirements defined by the ATX 3.0 design guide. Total +12V output reaches the full 1000 W capacity on a single rail. Cable length and routing must accommodate the 160 mm chassis depth. Input voltage spans 100 to 240 V at 50/60 Hz for worldwide use.

Questions about this item

How loud and hot does the 135 mm fan get when the unit runs at full load all day?

The 135 mm fan is the only moving part; at full load it moves enough air to keep internal temperatures within the 105 °C capacitor rating while meeting both 80 PLUS Gold and Cybenetics Gold efficiency targets, so waste heat and noise stay low.

Which cables must I already have to connect this supply to my motherboard and drives?

You need a motherboard with a 20+4 pin ATX socket and a CPU 12V connector; all PCIe, SATA and peripheral cables are included in the full-modular set, so no extra cables are required.

Will the single 12V rail and 12VHPWR connector work safely with my older graphics card that uses 6+2 pin plugs?

Yes, the package includes two 12VHPWR-to-dual-6+2 adapters plus six native 6+2-to-6+2 cables, so legacy cards draw from the same single 12V rail without adapters you must buy separately.
