Description
The ADATA XPG CORE REACTOR II 850W represents a significant evolution in power delivery, specifically engineered to handle the massive power excursions of modern GPUs. By adhering to the ATX 3.0 and PCIe 5.0 specifications, this unit can sustain power spikes up to 235% of its rated capacity. Its compact 140mm depth ensures compatibility with a wide range of chassis, while the fully modular design allows for a clean, professional build with optimized airflow.
This product is for:
- High-end gamers utilizing NVIDIA RTX 40-series cards who require a dedicated 12VHPWR 600W cable.
- PC builders looking for a compact 140mm PSU to maximize cable management space in mid-tower cases.
- Enthusiasts who prioritize long-term reliability with 100% Japanese 105°C capacitors and a 10-year warranty.
- Content creators running multi-core CPUs and demanding workstations that require 80 PLUS Gold efficiency.
- Silent-focused users who benefit from the 120mm Fluid Dynamic Bearing (FDB) fan and intelligent thermal control.

- Fan Specification: 120mm Fluid Dynamic Bearing (FDB), 2400 RPM
- Power Excursion Support: Up to 235% of rated power for 100μs
- Connectivity: 1x 24-pin, 2x 8-pin EPS, 6x 6+2-pin PCI-E, 1x 12VHPWR (12+4 pin), 8x SATA
Operating the CORE REACTOR II is a seamless experience, characterized by its quiet operation and rock-solid stability. The intelligent fan curve ensures that the 120mm FDB fan remains nearly inaudible during light tasks, only ramping up when the system is under heavy load. The flexible, flat black cables are easy to route through tight corners, making the assembly process straightforward even for first-time builders. With its 850W capacity, it provides ample headroom for overclocking and future component upgrades.
Compared to the previous generation Core Reactor, the Version II introduces critical ATX 3.0 compliance, making it far more capable of handling the transient voltage spikes of modern hardware. While many competitors in the Gold-rated category still utilize a 160mm depth, the XPG model's 140mm footprint offers superior compatibility for compact builds. It also features a more comprehensive 8-level protection suite than many entry-level ATX 3.0 units, positioning it as a premium choice for system safety.
Q&A:
- Does this PSU support the NVIDIA RTX 4090? Yes, the 850W model includes a native 12VHPWR cable capable of delivering up to 600W to the GPU.
- What is the benefit of ATX 3.0? ATX 3.0 is designed to handle high power excursions, preventing system shutdowns during sudden GPU power spikes.
- Is the fan loud during gaming? No, the Fluid Dynamic Bearing fan is controlled by a smart thermal sensor to maintain a low noise profile even under load.
- Can I use this in a Micro-ATX case? Yes, its 140mm length is standard for ATX but compact enough to fit comfortably in most Micro-ATX and small form factor ATX cases.
- What does the 10-year warranty cover? The warranty covers all internal components against manufacturing defects, reflecting the high quality of the Japanese capacitors used.
