Review SUPERMICRO 1u 650w Single Output Power Supply Pmbus 1.2

The Supermicro PWS-655P-1HS is a high-performance, 1U form factor power supply unit (PSU) designed for data center and other IT environments where space and efficiency are critical. This single, 650-watt PSU conforms to the latest PMBus 1.2 standard, enabling advanced monitoring and control of power delivery and system health.

Supermicro's PWS-655P-1HS is a 120mm fan-cooled unit, ensuring quiet operation even under heavy loads. Its compact, 1U design makes it an ideal choice for space-constrained environments and allows for optimal use of rack space. The PSU features a modular design with detachable cables for easier installation and maintenance.

Power delivery efficiency is a significant concern for IT professionals, and the PWS-655P-1HS addresses that need with 80 PLUS Platinum certification. This certification guarantees high levels of efficiency (up to 92% under typical loads) throughout the entire operating range, reducing waste heat and leading to energy savings.

Featuring a ( )12V output voltage and twelve (12) units of (-)12V outputs (-12V1 through -12V12), this unit can provide a variety of power configurations to meet the requirements of diverse IT systems. Its robust design ensures that it can deliver power reliably under demanding conditions.

The PWS-655P-1HS is compliant with various industry standards, including EN 55011, EN 55032, EN 55035, FCC Class B, and IEC 60950, ensuring a high level of safety and electromagnetic compatibility. Moreover, it undergoes extensive testing to meet Supermicro's rigorous quality standards, providing end users with a reliable and trustworthy power solution.

This single 650-watt power supply unit offers excellent performance, efficiency, and flexibility for IT infrastructure deployments, making it an ideal choice for small data centers, edge computing environments, and other applications where power reliability is essential.

Product: Supermicro PWS-655P-1HS 1U 650W Single Power Supply (Part Number: 672042118038)

Pros:

1. High efficiency: The power supply offers power efficiency up to 93.3% at 50% load, which can help save energy and reduce operating costs.

2. PMBus 1.2 Compliance: This power supply is compliant with PMBus 1.2, which is an advanced monitoring interface for power supplies, allowing for more granular power management.

3. Redundancy: As a single power supply, it might not offer hot-plug redundancy, but it still provides a reliable power source for most low-power systems.

4. Form factor: A compact, 1U height makes this power supply suitable for rack-mounted systems with limited space.

5. Rails-Plus design: Rails-Plus design ensures that the DC outputs are regulated, providing constant voltage and increased reliability.

Cons:

1. Lack of Redundancy: Since it is a single power supply, it does not offer the redundancy of a dual or multiple power supply setup.

2. Limited Power Capacity: A 650W capacity may not be sufficient for powering high-performance systems or dense clusters with numerous servers.

3. Modularity: It does not offer modular design, meaning that users cannot replace failed components individually, requiring a replacement of the whole power supply.

Conclusion:

The Supermicro PWS-655P-1HS is a compact and efficient power supply suitable for low-power 1U systems. Its PMBus 1.2 compliance provides advanced power management features, while its high efficiency contributes to energy savings. However, it lacks power capacity, hot-plug redundancy, and modular design, which might be limitations for certain applications.

Recommendation:

If your system has limited space, low power requirements, and does not necessitate hot-plug redundancy or high capacity, the Supermicro PWS-655P-1HS could be a suitable choice. If additional power capacity, hot-plug redundancy, or modularity is needed, it would be recommended to consider higher wattage, redundant, or modular power supplies.
