Modular Design and Cable Management

The MWE Gold V2 features a fully modular cabling system that allows users to attach only the cables they need. This design reduces clutter inside the case, improves airflow, and simplifies future upgrades or rebuilds.

• 24‑Pin ATX Connector: Provides power to the motherboard.
• 8‑Pin EPS Connector: Supports high‑power CPUs with additional voltage regulation.
• 4 x PCI Express (6+2 pin): Ideal for multi‑GPU setups or powerful graphics cards.
• 8 SATA Power Connectors: Sufficient for multiple storage devices.
• 4 Molex (Peripheral) Connectors: For legacy peripherals and fans.

Cooling Performance

The unit is equipped with a single, high‑quality 120 mm HDB fan, engineered for low noise operation. The fan’s 23.4 dB sound level ensures that the PSU remains virtually silent even under full load.

• Active Cooling: Maintains optimal operating temperatures.
• Operating Temperature Range: 0–50 °C – suitable for most indoor environments.

Power Factor Correction (PFC)

The PSU incorporates an Active PFC circuit, which improves power factor and reduces harmonic distortion. This feature not only enhances efficiency but also protects the unit from voltage fluctuations.

Protection Features

Safety is paramount in any high‑power component. The MWE Gold V2 includes comprehensive protection mechanisms:

• Over Current (OCP)
• Over Power (OPP)
• Over Voltage (OVP)
• Under Voltage (UVP)
• Short Circuit (SCP)
• Overheating (OTP)

Form Factor and Compatibility

This power supply adheres to the standard ATX form factor, making it a drop‑in replacement for most mid‑tower cases. Its black chassis blends seamlessly with contemporary builds, while the modular cabling system allows for clean, cable‑managed interiors.
