Power supply EVOLVEO G850 850W 80+ Gold ATX 3.1 modular, aPFC, 140 mm fan, white

The EVOLVEO G850 is an ATX 3.1 power supply delivering up to 850W continuous output with 80+ Gold efficiency. Designed for high-performance desktop systems, it features modular cabling, active power factor correction (aPFC) and a quiet 140 mm cooling fan. The unit includes an ATX 24‑pin main connector, dual 8‑pin CPU connectors, PCIe 8‑pin and PCIe 16‑pin Gen5 outputs plus a comprehensive set of 15 SATA and Molex connectors to support multiple drives and peripherals. The white housing and modular design simplify cable management while maintaining stable power for gaming rigs and workstations.

Advantages

EVOLVEO G850 combines high efficiency and modern ATX 3.1 compatibility to reduce energy losses and support the latest platform power requirements. Modular cables allow cleaner builds and easier installation, and active PFC increases power stability and reduces electrical noise. The 140 mm fan balances airflow and acoustic performance for sustained cooling under load. Inclusion of both PCIe 8‑pin and PCIe 16‑pin Gen5 connectors accommodates current and next‑generation graphics cards without adapters.

Suitable for

• Gaming desktops with single or multi‑GPU configurations
• High‑performance workstations for content creation and 3D rendering
• Systems requiring multiple storage drives and peripherals
• Upgrades to ATX 3.1 compliant motherboards and components

When it may not be suitable

The G850 is optimized for ATX systems and high‑power builds; it may be oversized for small form factor or low‑power office PCs where a lower wattage, more compact PSU would be more appropriate. Installers should verify case clearance and airflow in compact enclosures to ensure the 140 mm fan and cable routing can be accommodated.

How to use

Mount the EVOLVEO G850 in a compatible ATX case following standard PSU orientation and secure it with the supplied screws. Connect the ATX 24‑pin and CPU 8‑pin connectors to the motherboard first, then attach PCIe and storage power cables as required. Use only the modular cables provided with the unit and route them to maintain clear airflow. Ensure the PSU is connected to a properly rated mains outlet and powered off before connecting or disconnecting components. After initial installation, monitor system stability and fan noise during the first full‑load sessions.

What to consider before purchase

• Verify system power draw to ensure 850W is appropriate for your components
• Confirm case clearance for a PSU with a 140 mm fan and modular cable routing
• Check motherboard and GPU connector requirements to match available CPU and PCIe outputs
• Plan cable lengths and modular connector placement for your case layout

Usage recommendations

For optimal performance, pair the EVOLVEO G850 with an ATX 3.1 compatible motherboard and use the native PCIe 16‑pin Gen5 connector for supported graphics cards. Keep ventilation unobstructed and perform periodic dust cleaning to preserve efficiency and cooling.
