Review SILVERSTONE TECHNOLOGY 450w Sfx Form Factor Plus Bronze Power Supply
The SilverStone ST45SF-V3 is a compact, yet powerful SFX (Small Form Factor) power supply unit (PSU) designed to cater to the needs of enthusiasts who prioritize space efficiency in their small form factor PC builds. With a capacity of 450 watts, this 80 Gold certified PSU offers reliable and efficient power delivery.
The unit's dimensions are 120mm (W) x 62.5mm (H) x 140mm (D), making it an excellent choice for mini-ITX and other small form factor cases. The SFX form factor allows for a more vertical layout, which can save valuable space within the case.
The ST45SF-V3 employs high-quality components, including Japanese capacitors, to ensure a long lifespan and stable performance. It also features Active PFC (Power Factor Correction) with PF value of 0.99, which ensures optimal power draw from the wall outlet and reduces energy waste.
The PSU comes equipped with a single 12V rail, capable of delivering up to 37.5A. This design simplifies cable management and reduces potential issues related to voltage distribution among multiple rails. The unit also includes a 20-pin main motherboard connector, 4 4-pin EPS12V connector, and a total of 5 PCIe connectors, which can support high-end graphics cards and other demanding components.
SilverStone's ST45SF-V3 has a semi-modular design, allowing users to connect only the cables they need, making cable management easier and reducing clutter inside the case. Additionally, it includes a 122mm long 3-pin fan with a fluid dynamic bearing that ensures quiet operation and long life, with a maximum speed of 1,500 RPM.
This 450W SFX power supply is backed by a 5-year warranty, providing peace of mind and ensuring reliable operation for your small form factor PC build.
The SilverStone SFX (Small Form Factor) Power Supply Unit (PSU) ST45SF-V3 is a popular choice for those building small form factor PCs. Here are some pros and cons that can help in making an informed decision about purchasing this PSU:
Pros:1. High efficiency: The ST45SF-V3 has an 80 Plus Gold certification, which means it operates at up to 90% efficiency under typical loads, making it an energy-efficient choice.
2. Compact size: Its SFX form factor makes it suitable for small cases, and it can easily fit in most mini-ITX and micro-ATX builds.
3. Quiet operation: This PSU has a fan that runs at low RPMs under typical loads, ensuring quiet operation.
4. Good build quality: SilverStone is known for its high-quality components and robust construction.
5. Modular cables: The modular design of the cables allows users to configure their system with only the necessary cables, reducing clutter and improving airflow.
Cons:1. Limited power output: With a capacity of only 450W, this PSU may not be suitable for high-end systems with multiple high-performance components.
2. Limited connectors: The PSU only comes with a few PCIe connectors, which may not be enough for multi-GPU setups.
3. No semi-passive operation: The fan on this PSU runs at all times, even under light loads, which can contribute to additional noise and energy consumption.
In conclusion, the SilverStone ST45SF-V3 is an excellent choice for those building small form factor systems with moderate power requirements. Its high efficiency, quiet operation, and modular design make it a popular choice among enthusiasts and PC builders. However, for high-end systems with multiple high-performance components, a larger and more powerful PSU may be necessary.
Based on the given information, if you're building a small form factor system with moderate power requirements, the SilverStone ST45SF-V3 is a solid choice. However, if you're planning on building a high-performance system with multiple GPUs, you may want to consider a larger and more powerful PSU with more connectors.
