850 W ATX 3.0 power supply

The XPG Corereactor II 850 W unit is a fully modular power supply built to the Intel ATX 12V v3.0 design guide. It delivers a single +12 V rail and includes a native 12VHPWR 12+4 pin connector alongside four PCI-E 6+2 to 6+2 pin and two additional PCI-E 6+2 pin cables. Eight SATA power connectors and a 20+4 pin main connector complete the cable set. The 150 mm depth fits most standard ATX cases.

Dual Gold efficiency and Japanese capacitors

Certified 80 PLUS Gold and Cybenetics Gold, the supply achieves a 0.99 active PFC across a 100 to 240 V input range. All electrolytic capacitors are 105 °C rated Japanese components, and the platform includes eight industrial protection circuits. A 120 mm fan provides cooling, while the 100 000 hour MTBF at 25 °C reflects the build quality. The unit suits builders who want ATX 3.0 readiness and full modularity; those needing higher wattage or a different form factor should look elsewhere.

Native 12VHPWR connector for PCIe 5.0 graphics

The defining specification is the inclusion of a 12VHPWR 12+4 pin connector compliant with the PCIe 5.0 and ATX 3.0 standards. This single cable replaces multi-cable adapters on compatible graphics cards and ensures the power delivery required by current high-end GPUs. If your graphics card uses the 12VHPWR interface, this supply connects directly; if it does not, the additional PCI-E 6+2 pin cables cover traditional power needs.

商品問答

Will the 12VHPWR connector work with an older GPU that only uses 6+2 pin cables?

Yes, the unit includes four 6+2-to-6+2 PCIe cables and two additional 6+2 pin cables alongside the 12VHPWR connector, so legacy cards are supported.

How can I verify the 120 mm fan and single +12 V rail are operating correctly after installation?

Check that the 120 mm fan spins at startup and monitor the +12 V rail voltage in BIOS or software; it should remain close to 12 V under load with the 80 PLUS Gold and Cybenetics Gold certifications confirming efficiency.

Which cables come in the box and what must I buy separately for a typical build?

The fully modular package supplies the 20+4 pin ATX cable, one 12VHPWR 12+4 pin cable, four 6+2-to-6+2 PCIe cables, two 6+2 PCIe cables and eight SATA connectors; no extra cables are required for standard motherboard GPU and drive connections.
