The XPG CORE REACTOR II 1000W provides a strong +12V rail rated at 83.5A, giving the PSU substantial capacity for modern high-performance processors and graphics cards. The +5V and +3.3V rails are rated at a combined 22A.

Key Benefits

• 1000W total power
• 83.5A +12V output
• Designed for high-performance CPUs and GPUs
• Stable power delivery for demanding workloads
• Suitable for gaming, workstation, and creator PCs

235% Power Excursion Capability

The CORE REACTOR II 1000W is designed to handle short-duration power excursions of up to 2350W, equivalent to 235% of its rated 1000W output for 100 microseconds. This is particularly relevant to modern graphics cards that can produce brief power spikes during demanding workloads.

Benefits

• Up to 235% power excursion
• Handles short-duration GPU power spikes
• Designed around modern ATX requirements
• Helps improve system stability
• Suitable for demanding gaming and rendering workloads

ATX 3.1 and 12V-2×6 Support

The current XPG specification lists the CORE REACTOR II as ATX 3.1 compliant and equipped with a 12V-2×6 (12+4-pin) connector rated for 600W. This provides native connectivity for compatible modern graphics cards.

Benefits

• ATX 3.1 compliant
• 12V-2×6 GPU connector
• 600W-rated 12V-2×6 connection
• Modern GPU compatibility
• Cleaner GPU power installation

Note: Older CORE REACTOR II documentation may refer to ATX 3.0 and a 12VHPWR connector. XPG’s current specification now identifies the platform as ATX 3.1 with 12V-2×6, so this is the specification to use for the current product listing.

Extensive PCIe Connectivity

The 1000W model provides eight PCIe 6+2-pin connectors in addition to the dedicated 12V-2×6 connector. This offers considerable flexibility for graphics cards and other PCIe-powered components.

Connectivity

• 1 × ATX 24-pin connector
• 2 × EPS 8-pin connectors
• 8 × PCIe 6+2-pin connectors
• 1 × 12V-2×6 connector
• 3 × 4-pin Molex connectors

This extensive connector selection makes the 1000W version suitable for a wide range of high-performance configurations.

Dual EPS 8-Pin CPU Support

The CORE REACTOR II 1000W includes two EPS 8-pin CPU power connectors, making it suitable for motherboards that provide multiple CPU power inputs.

Benefits

• 2 × EPS 8-pin connectors
• Suitable for high-performance CPUs
• Supports motherboards with multiple CPU power inputs
• Useful for enthusiast and workstation configurations

135mm Fluid Dynamic Bearing Fan

The 1000W version uses a larger 135mm Fluid Dynamic Bearing fan. XPG specifies a maximum fan speed of 2400 RPM and an MTBF of 100,000 hours at full load.

The intelligent fan-curve design is intended to keep the fan operating at lower RPM when possible, helping balance cooling performance and acoustic output.

Benefits

• 135mm FDB fan
• Fluid Dynamic Bearing
• Up to 2400 RPM
• 100,000-hour MTBF at full load
• Intelligent fan curve
• Designed for quieter operation

Cybenetics Platinum Efficiency Rating

In addition to its 80 PLUS Gold certification, XPG’s current specifications list the CORE REACTOR II 1000W with a Cybenetics Platinum efficiency rating.

This provides an additional efficiency classification beyond the familiar 80 PLUS rating.

Efficiency Highlights

• 80 PLUS Gold
• Cybenetics Platinum
• Up to 91.40% efficiency at 50% load under the 115V 80 PLUS test conditions specified by XPG
• PFC greater than 0.99

100% Japanese 105°C Capacitors

XPG uses 100% Japanese 105°C-rated capacitors in the CORE REACTOR II series. These components are designed to provide stable operation under demanding temperatures and loads.

Benefits

• Japanese capacitors
• 105°C temperature rating
• High-temperature reliability
• Stable power delivery
• Designed for long-term operation

Fully Modular Cable System

The CORE REACTOR II 1000W features a fully modular cable design, allowing users to install only the cables required by their particular system.

This helps reduce cable clutter and can make installation easier, especially in systems with limited cable-routing space.

Benefits

• Fully modular
• Cleaner internal appearance
• Easier cable management
• Improved installation flexibility
• Fewer unused cables inside the case

Compact 160mm PSU Chassis

The 1000W model measures 160 × 150 × 86mm. Despite its high 1000W capacity, the 160mm length keeps the unit relatively compact for a high-output ATX power supply.

Dimensions

Length: 160mm
Width: 150mm
Height: 86mm

Benefits

• Compact 160mm length
• Standard ATX format
• Easier case compatibility
• More room for cable routing
• Suitable for many modern gaming cases

Complete Connector Configuration

XPG’s official specification confirms this connector configuration for both the 1000W and 1200W models.

Protection Features

The CORE REACTOR II includes eight protection mechanisms designed to protect the PSU and connected PC hardware.

Protection Systems

• OCP — Over Current Protection
• OVP — Over Voltage Protection
• OPP — Over Power Protection
• OTP — Over Temperature Protection
• UVP — Under Voltage Protection
• SCP — Short Circuit Protection
• NLO — No Load Operation Protection
• SIP — Surge & Inrush Protection

These protections help safeguard the power supply and system components against different abnormal electrical conditions.
