• Efficiency: 88 % at 50 % load (80 PLUS Bronze).
• Active Power Factor Correction (PFC): Yes – improves power quality and reduces harmonic distortion.
• Dimensions: Height 140 mm, Width 150 mm, Depth 86 mm.
• Weight: 1.5 kg.
• Form Factor: ATX (2.4).

Cable and Connector Layout

The semi‑modular cable set includes:

• 1 × 20‑pin + 4‑pin ATX motherboard connector.
• 1 × 24‑pin ATX12V 2.x power connector for the CPU.
• 1 × 4+4‑pin +12 V CPU power connector.
• 2 × 6+2‑pin PCI Express connectors (suitable for dual‑GPU setups).
• 6 × 15‑pin SATA power cables.
• 3 × 4‑pin Molex peripheral connectors.
• 1 × EPS connector for server or workstation CPUs.

Cooling and Noise Management

The unit houses a single 120 mm fan mounted at the top of the PSU. The fan employs an automatic speed control algorithm, ramping up only when temperatures rise, thereby keeping noise levels low during idle or moderate workloads. The fan’s placement ensures efficient exhaust of hot air from the case, contributing to overall system thermals.

Design and Build Quality

The NE650M features a robust metal chassis with reinforced corners for durability. Its black finish offers a sleek aesthetic that blends seamlessly with contemporary PC builds. The PSU complies with CE, TÜV, CB, EAC safety certifications, guaranteeing adherence to stringent European and international standards.

Compatibility and Use Cases

This power supply is ideal for:

• Mid‑range gaming rigs that require a single high‑quality GPU or dual GPUs with moderate power demands.
• Content creation workstations where stable +12 V rail delivery supports multiple storage devices and professional graphics cards.
• Home office PCs needing reliable performance without excessive noise.

Operating System Support

The NE650M is fully compatible with Windows, Linux, and other mainstream operating systems that run on ATX motherboards. Its modular cabling and clean design make it straightforward to integrate into a wide variety of case sizes.

Efficiency and Environmental Impact

With an 80 PLUS Bronze rating, the PSU delivers 88 % efficiency at half load. This high efficiency reduces power consumption and heat output, contributing to lower electricity bills and a cooler operating environment. The active PFC further enhances energy savings by minimizing reactive power usage.

Installation Tips

• Place the PSU with the fan facing upward or toward the rear exhaust vent for optimal airflow.
• Use the semi‑modular cables to connect only the components you need, leaving unused cables disconnected to reduce clutter.
• Ensure that the 24‑pin ATX12V connector is firmly seated on the motherboard’s CPU power socket for stable voltage delivery.

Conclusion

The Antec Neo Eco NE650M combines solid build quality, efficient performance, and a user‑friendly semi‑modular cable system. Its 650 W output is sufficient for most gaming and workstation configurations, while the active cooling strategy keeps noise to a minimum. Whether you’re building a new desktop or upgrading an existing setup, this PSU offers reliable power delivery backed by industry‑standard safety certifications.
