ADATA XPG CORE REACTOR II VE 850G (850W) 80 Plus Gold PSU ATX 3.1 PCIe 5.1

ADATA XPG CORE REACTOR II VE 850G is an 850W modular ATX power supply from the higher mid-range class, aimed at modern gaming and workstation configurations. With 80+ Gold certification and around 90% efficiency, you get stable and relatively cool power, suitable for powerful GPU and CPU combinations. Support for ATX 3.0/3.1 and PCIe Gen 5.0/5.1 and the available 12VHPWR (600W) connector make it ready for the latest graphics cards. Despite its serious capabilities, the case is compact – 140 x 150 x 86 mm, which helps in tighter cases.

What you get

850W power is more than enough for configurations with a powerful GPU and multi-core processor, even under serious gaming or rendering pressure. Interestingly, the power supply is designed to handle up to 1997W for 100μs (up to 235% of the nominal), which is important for short peak consumption of modern graphics cards. The modular design allows you to connect only the necessary cables – this means better airflow and a cleaner internal appearance of the case. A 120mm F.D.B. fan takes care of cooling with lower noise and longer life compared to standard bearing solutions. A full set of protections (OVP, OPP, SCP, OCP, UVP, OTP, NLO, SIP) are built in to protect your components from power issues and overheating.

• Power of 850W, suitable for strong gaming and workstation configurations with high-end GPU and multi-core CPU.
• 80+ Gold certification and around 90% efficiency at typical load mean less energy loss and lower heat.
• Full support for ATX 3.0/3.1 and PCIe Gen 5.0/5.1 with 12VHPWR (12+4 pin, 600W) connector for modern graphics cards.
• Rich set of connectors: 6x PCI-E 6+2 pin, 2x EPS 8 pin, 8x SATA, and 4x Molex, covering many GPUs, SSDs, HDDs, and peripherals.
• Modular cable design that facilitates cable management and improves airflow in the case.
• 120mm F.D.B. fan for quieter operation and better durability over time compared to standard fans.
• Full set of protections OVP / OPP / SCP / OCP / UVP / OTP / NLO / SIP for greater security of components and the PSU itself.
• Compact dimensions 140 x 150 x 86 mm in standard ATX format, suitable for shorter PSU tunnels.

Who it is suitable for

This power supply is a good foundation for a serious gaming build, streaming, or workstation with a modern graphics card, including models with a 12VHPWR connector. It is suitable if you plan upgrades and want a PSU that can handle the peak consumption of new GPUs. It is not the most logical choice for completely budget systems or small office configurations where 850W and ATX 3.1 would be excessive.

The most sensible aspect here is the combination of ATX 3.1, 12VHPWR, 80+ Gold efficiency, and modular design in an 850W format – powerful enough and ready for the next generations of hardware.
