The SilverStone Strider Essential Series SST-ST50F-ES230 is a high-performance ATX12V switching power supply designed to provide reliable and efficient power for a wide range of computer systems. This power supply is engineered to meet the demands of modern computing, offering robust power delivery and a suite of features that ensure stable and safe operation.
At its core, the SST-ST50F-ES230 serves as the central power unit for a computer system, converting alternating current (AC) from a wall outlet into direct current (DC) that various components within the computer require. It is a single-phase 500-watt power supply with five distinct output rails, ensuring that all parts of the system receive the appropriate voltage and current. The power supply incorporates Active Power Factor Correction (PFC) circuitry, which helps to improve power efficiency and reduce harmonic distortion on the AC line, making it more environmentally friendly and compliant with international standards like EN61000-3-2.
One of the key functions of this power supply is its ability to deliver continuous power output even under demanding conditions, specifically at an operating temperature of 40°C. This ensures system stability and longevity, even in environments where heat management might be a concern. The design prioritizes a class-leading single +12V rail, which is crucial for powering high-demand components such as graphics cards and processors, ensuring they receive a stable and ample power supply.
The SST-ST50F-ES230 also features a remote On/Off controlled mode, allowing the system to remotely turn the power supply on or off via the PSON# signal. This active low signal is a standard feature in ATX power supplies, enabling the motherboard to control the power state of the system. When the PSON# signal is not pulled low or is left open, the main outputs (except for the +5VSB standby voltage) turn off. The signal is internally pulled to a standby voltage by a pull-up resistor, ensuring proper default behavior.
A critical function is the PG-OK (Power Good) signal, which indicates to the system that the power supply's +5VDC and +3.3VDC outputs are above their respective under-voltage thresholds and that sufficient mains energy is stored for continuous operation. This signal is essential for an orderly system startup, preventing components from receiving unstable power. Conversely, if these voltages drop or mains power is removed for a sufficient duration, the PG-OK signal deasserts, signaling the system to shut down safely.
The SST-ST50F-ES230 is designed for ease of integration and reliable performance in various computer builds. Its high efficiency, greater than 80% (with a maximum of up to 85%), means less energy is wasted as heat, contributing to lower operating costs and a cooler system environment. This efficiency is measured at full load under 230V/50Hz conditions, highlighting its performance in typical European and Asian power grids.
The power supply supports a wide range of connectors, including a 24-pin M/B connector, ATX 12V 4-pin, 4-pin peripheral (HDD), 4-pin floppy, SATA, 8-pin PCI Express, and 6-pin PCI Express connectors. This comprehensive array of connectors ensures compatibility with a broad spectrum of motherboards, storage devices, and graphics cards, including those requiring dedicated PCI-E 8-pin and 6-pin connectors for high-power graphics processing units.
Silent operation is a notable usage feature, achieved through a 120mm fan that runs at a low noise level of 18dBA. This makes the SST-ST50F-ES230 suitable for users who prioritize a quiet computing experience, such as those building home theater PCs or workstations where noise reduction is important.
The power supply is designed to handle various load conditions, from light to full load, maintaining stable voltage regulation within specified ranges. It also features robust startup capabilities, ensuring it can power up normally with or without a connected load, and even after a cold start (storage in 0°C environment for 4 hours). The ability to handle significant capacitive loads on its DC outputs further enhances its reliability during system startup and operation.
While power supplies are generally low-maintenance components, the SST-ST50F-ES230 incorporates several design elements that contribute to its long-term reliability and ease of troubleshooting. The inclusion of multiple protection circuitries is a key maintenance feature, as these systems automatically safeguard the power supply and connected components from various electrical faults.
These protection mechanisms include:
The power supply's Mean Time Between Failures (MTBF) is specified at 50,000 hours minimum, indicating a high level of reliability and a reduced likelihood of failure over its operational lifespan. This robust design minimizes the need for frequent maintenance or replacement.
For quality assurance and long-term stability, the SST-ST50F-ES230 undergoes a burn-in process. This involves applying 75% loads in a 40°C (+/-5°C) chamber for 4 hours, which helps to identify and eliminate potential early-life failures, ensuring that units shipped to customers are robust and reliable.
The product's compliance with various safety and electromagnetic compatibility (EMC) standards, such as FCC, CE, TUV, and CB, ensures that it meets stringent international requirements for electrical safety and electromagnetic interference. This not only guarantees safe operation but also simplifies integration into systems that must meet these regulatory standards.
In summary, the SilverStone Strider Essential Series SST-ST50F-ES230 is a meticulously engineered power supply that offers stable, efficient, and protected power delivery for a wide range of computer applications. Its comprehensive features, from robust power output to multiple protection mechanisms and quiet operation, make it a reliable choice for users seeking a dependable foundation for their computing systems.
