Enermax CyberG II 850W ATX 3.1 Power Supply

850W80 Plus GoldATX 3.1 / 12V-2x6Japanese Caps
The Enermax CyberG II 850W is an ATX 3.1 power supply with 80 Plus Gold efficiency (up to 93%), built as a value-focused choice for gaming PCs and creative workstations that need modern GPU support. It carries part number ERV850G-AHG-NAC (EAN 4713157728968) and includes a native 600W 12V-2x6 cable for current-generation graphics cards. Built with 100% industrial-grade Japanese capacitors and non-modular black flat cables, it handles 2x total and 3x GPU power excursions and is certified to run at 40°C and altitudes up to 5,000 m. Typically in stock with fast delivery across Cyprus.
Good to know before you buy
This is a non-modular power supply — the black flat cables are permanently attached, not detachable. It is fully ATX 3.1 compliant with a native 12V-2x6 (12+4 pin) cable that connects directly to current-generation GPUs — no adapter needed; older cards use the 6+2 PCIe leads. Provides two CPU/EPS connectors. Fits any case taking a standard ATX PSU at a compact 140 mm depth (140 × 150 × 86 mm).

Best For

✓Value gaming PCs with a PCIe 5.1 GPU

Frequently Asked Questions

Is the CyberG II 850W modular?
No. It is a non-modular power supply, so all cables are permanently attached. The black flat cables are designed for easy installation, but you cannot remove unused cables as you can on a modular unit.
Does it support the latest RTX graphics cards?
Yes. It includes a native 600W 12V-2x6 (12+4 pin) cable that plugs directly into current-generation PCIe 5.1 GPUs without an adapter, and ATX 3.1 compliance handles their transient power spikes.
Is 850W enough for a high-end gaming build?
For a single high-end GPU with a modern CPU, 850W gives comfortable headroom and keeps the unit in its efficient load band. It also suits creator and editing workstations.
What is the difference between the CyberG II and the Revolution III?
Both are 850W ATX 3.1 / 80 Plus Gold units with a native 12V-2x6 cable and Japanese capacitors. The CyberG II is the value option with non-modular flat cables, while the Revolution III is fully modular with mesh-sleeved cables and a cable comb kit.
Singular Expert Insight
The CyberG II 850W is Enermax's budget route to Genuine ATX 3.1: you still get a native 12V-2x6 cable, 80 Plus Gold efficiency and 100% Japanese capacitors, with the cost saving coming from non-modular cabling and a sleeve-bearing fan. It is a sensible pick for value builds that don't need detachable cables. If you want fully modular cabling and a quieter FDB fan, the Enermax Revolution III 850W is the step up in the same family.
