Who it fits

Enermax CYBERG II Key Specs

Wattage: 850W

This value indicates the continuous power output the unit can deliver. You can use this rating to ensure your CPU and GPU have enough energy during heavy loads. It fits mid-range to high-end builds. If your components draw more than 850W, you need a higher wattage unit. Always leave some headroom for peak usage spikes.

Modularity: Non-Modular

All cables are permanently attached to the power supply. You cannot unplug or swap individual cables. This design often reduces cost but requires managing all cable lengths. It suits cases with ample space for cable routing. If you prefer a clean look with minimal excess wire, this might not be the best choice for tight builds.

ATX Version: ATX 3.1

This standard ensures compatibility with the latest motherboards and components. It supports modern power delivery requirements for new CPUs and GPUs. You benefit from improved stability and signaling. Older systems may not fully utilize these features. When shopping, check that your motherboard supports this version for optimal performance and safety.

Efficiency Rating: 80 Plus Gold

This rating measures how effectively the PSU converts AC power to DC power. A Gold rating means it wastes less energy as heat. This lowers electricity costs and reduces internal temperatures. It is more efficient than Bronze units. You get better performance per watt, which helps keep your system cooler and quieter during operation.

Design and build details

The Enermax CYBERG II measures 5.91 inches in length, 5.51 inches in width, and 3.39 inches in height. These dimensions fit the standard ATX form factor. You can install this unit in most mid-tower and full-tower cases that support standard power supply bays. The non-modular design means all cables are fixed to the unit. You must route every wire from the chassis back. This layout requires careful cable management inside your case. Flat black cables help hide behind motherboard trays and maintain a clean look.

The listing states the unit weighs 41 pounds. This mass suggests a heavy internal structure. A sturdy chassis helps protect components during shipping and installation. The finish is black, matching the standard aesthetic of most PC cases. Inside, the design uses 100% Japanese capacitors. These components are known for long-term stability. The unit also features six protective circuits. This safety design helps guard against electrical faults.

According to the listing, the fan is a 120mm sleeve-bearing type. Sleeve bearings are common in budget to mid-range units. They offer reliable operation but may be slightly louder than fluid dynamic bearing fans at high speeds. The unit is certified for operation at altitudes up to 5,000 meters. This rating means the cooling system performs well even in thinner air. You do not need to worry about overheating in high-altitude environments or poorly ventilated cases.

Setup and daily operation

Setup begins with connecting the fixed cables. Since this unit is non-modular, you must manage all wires inside your case. The flat black cables help keep the interior looking clean. You will need to route the main 24-pin connector to your motherboard and the CPU power cables to your processor. The included 12V-2x6 cable connects directly to modern graphics cards. This single cable supports up to 600W and handles power excursions up to 200%. This capability ensures stable voltage during sudden load spikes from your GPU. You do not need adapters for new cards that use the 12V-2x6 standard. Daily operation relies on the 120mm sleeve-bearing fan. This fan size is standard for ATX cases. It runs quietly under normal loads. The unit maintains high efficiency at up to 93% thanks to its 80 Plus Gold rating. This means less wasted energy as heat. The internal components include 100% Japanese capacitors. These parts support long-term reliability. The power supply includes six protective circuits. These circuits guard against electrical faults. You can use this unit at altitudes up to 5,000 meters. The design supports stable performance in various environments. You get consistent power delivery without needing to swap cables. The non-modular design simplifies installation for users who prefer a straightforward setup. You connect the cables once and leave them. The fixed nature means you cannot remove unused wires. This keeps the cable count static. The unit fits standard ATX cases. You verify your case length can accommodate the 5.91-inch depth. The 850W output covers most high-end builds. You ensure your total system draw stays below this limit for optimal efficiency.

Before You Buy Enermax CYBERG II

You need to verify your case has enough room for the 5.91-inch length. This unit is non-modular, so you must manage all cables yourself. Flat black wires help with aesthetics, but excess length can clutter your build. Check that your motherboard supports the ATX 3.1 standard for full compatibility. The 12V-2x6 connector handles modern GPUs well, but ensure your case airflow supports the 120mm fan. Altitude matters if you live above 5,000 meters. The sleeve-bearing fan requires dust cleaning to maintain silence. Compare this to modular options if you want cleaner builds. This unit suits users who prioritize raw output and standard ATX compatibility over cable management flexibility. It fits well in mid-tower cases with good airflow. Keep the area around the fan clear for longevity.

Check before you buy

• Verify your case fits the 5.91-inch length.
• Confirm ATX 3.1 motherboard support.
• Check airflow for the 120mm fan.
• Plan cable routing for non-modular design.
