The XPG CORE REACTOR II 1000W (model COREREACTORII1000G-BKCEU, part number 75261209, EAN 4711085942395) is a 1000-watt, fully modular ATX power supply built to the Intel ATX 3.0 (and ATX 3.1-compatible) design guide with a native PCIe Gen5 12VHPWR connector. It carries 80 PLUS Gold and Cybenetics Platinum efficiency, 100% Japanese 105 °C capacitors and the ability to withstand power excursions up to 235% of rated power — making it a robust, reliable foundation for high-performance gaming PCs and workstations, backed by a 10-year warranty.
Connector note: The CORE REACTOR II uses a native PCIe Gen5 16-pin 12VHPWR (12+4) connector per the ATX 3.0 design guide (the unit is also ATX 3.1 compatible). It is fully compatible with current 16-pin graphics cards; seat the connector firmly until it clicks. For older GPUs, use the supplied 6+2-pin PCIe cables instead.
Who It's For
The CORE REACTOR II 1000W suits high-end gaming and creator PCs — a flagship single GPU with overclocking headroom, or a power-hungry workstation. The 1000 W rating, native 12VHPWR cable, dual EPS and Generous storage connectors give comfortable margin for the latest RTX/Radeon cards plus fully loaded systems, while the 235% peak capability handles transient GPU spikes.
Key Features
ATX 3.0 with native PCIe 5.0 12VHPWR
A factory 16-pin 12VHPWR (12+4) cable connects the latest high-end GPUs directly and meets the ATX 3.0 design guide (ATX 3.1 compatible), handling power excursions up to 235% of rated power without nuisance shutdowns.
80 PLUS Gold + Cybenetics Platinum
Dual certification with efficiency up to 91.4% at 50% load means less wasted energy, lower heat and quieter, cooler operation.
100% Japanese 105 °C capacitors
Premium all-Japanese 105 °C-grade capacitors deliver stable, reliable power and long-term durability under sustained heavy load.
Semi-passive 135 mm FDB fan
An Intelligent Fan-Curve design keeps the 135 mm fluid-dynamic-bearing fan off at light and moderate loads for silent operation, spinning up only when cooling is needed.
Fully modular cabling
Connect only the cables your build needs for a cleaner layout and better airflow — including two EPS, eight PCIe 6+2, nine SATA and three Molex connectors.
8 protections + 10-year warranty
Eight industrial protections (OCP, OVP, OPP, OTP, UVP, SCP, NLO, SIP) safeguard your components, all backed by a 10-year warranty.

Frequently Asked Questions
Does the CORE REACTOR II 1000W support the latest RTX graphics cards?
Yes. It includes a native PCIe Gen5 16-pin 12VHPWR (12+4) connector, so current high-end GeForce RTX and Radeon cards connect directly with a single cable.
Is this ATX 3.0 or ATX 3.1?
It is built to the ATX 3.0 design guide and is also ATX 3.1 compatible, using the 16-pin 12VHPWR connector with full power-excursion support (up to 235% of rated power).
Is the fan always running?
No. The Intelligent Fan-Curve keeps the 135 mm fluid-dynamic-bearing fan off at light and moderate loads for silent operation, spinning up only under heavier demand.
Is it fully modular?
Yes — every cable is detachable, so you only install the connectors your build needs for cleaner cable management and better airflow.
What capacitors does it use?
It uses 100% Japanese 105 °C-grade capacitors for stability, reliability and long-term durability under load.
Expert Insight
The CORE REACTOR II is XPG’s value-enthusiast PSU, and it punches above its 80 PLUS Gold label: Cybenetics Platinum efficiency, 100% Japanese capacitors and a 235% peak-load rating put it on par with pricier units. The semi-passive 135 mm fluid-dynamic-bearing fan keeps it silent at typical gaming loads, and the connector loadout — dual EPS, eight PCIe 6+2 and nine SATA — is Generous enough for big multi-drive or even dual-GPU builds at 1000 W. Because it uses the 12VHPWR (12+4) connector per the ATX 3.0 guide (also ATX 3.1 compatible), it pairs perfectly with current cards. With a 10-year warranty backing it, this is a lot of well-built power for the money; step up to the 1200 W model if you need extra headroom.
