The Rosewill Tachyon-550 80 PLUS Platinum Semi-Modular Power Supply is a high-performance and energy-efficient power solution designed for modern computing systems. This power supply unit (PSU) is certified to meet the stringent requirements of the 80 PLUS Platinum standard, ensuring that it converts up to 92% of the input power into usable energy for the computer, thereby reducing energy waste and lowering operating temperatures.
This semi-modular design allows users to connect only the necessary cables to the components in their system, making cable management more efficient and reducing clutter. With a total capacity of 550 watts, the Tachyon-550 is ideal for supporting mid-range gaming systems, workstations, and high-performance home-theater PCs.
The power supply utilizes a 135mm double ball-bearing fan, ensuring quiet operation and longevity. The fan speed is adjustable through the semi-passive mode, where the fan remains off under low loads, making the system operation nearly silent. Additionally, the fan speed can be manually adjusted using the speed controller, allowing the user to fine-tune the fan curve to their desired preference.
The Tachyon-550 features a fully modular design, but in a semi-modular form factor, offering the best of both worlds: the ability to use only the cables required and the convenient management offered by modular design. The power supply includes a wide selection of individually sleeved cables, including 1 x 24-pin ATX, 1 x 8-pin EPS12V, 2 x 6 2-pin PCIe, and 6x SATA, among others.
The power supply's massive 50mm Japanese-made capacitors guarantee stable and reliable voltage delivery, preventing voltage fluctuations that can harm sensitive components in the system. The unit's fully automatic fan control and Over Voltage Protection, Under Voltage Protection, Short Circuit Protection, and Over Current Protection additional safeguards the components in the system from damage.
In summary, the Rosewill Tachyon-550 80 PLUS Platinum Semi-Modular Power Supply is an energy-efficient, quiet, and reliable power supply solution that delivers ample power and offers a semi-modular design, making it an excellent choice for modern computing systems seeking superior cable management and quiet operation.
a. High Efficiency: The Rosewill Tachyon-550 is a 80 Platinum certified power supply, which means it operates at an impressive efficiency level of 90-92% under typical loads, ensuring minimal energy waste.
b. Semi-Modular Design: This PSU features a semi-modular design, which allows you to connect only the cables that you need, reducing the amount of excess cabling and clutter inside your case.
c. Quiet Operation: The fan control system adaptively adjusts fan speed based on the temperature, ensuring quiet operation under normal loads and reducing the noise level during light gaming or desk work.
d. Fanless Mode: When the load is low enough, the power supply can operate in fanless mode, allowing for complete silence.
e. High-Quality Capacitors: The Tachyon-550 utilizes Japanese capacitors, which are widely recognized for their durability and reliability in power supplies.
2. Cons:a. Size: The power supply's dimensions (150mm x 86mm x 140mm) might not fit in some small form factor cases or tight spaces, so it's essential to check compatibility before making a purchase.
b. Limited Modularity: Although it is a semi-modular power supply, it doesn't offer as many modular options as fully modular units, meaning you may still have some excess cables from the fixed peripherals.
c. Limited Connector Layout: For CPUs with multiple 8-pin EPS12V connectors, you might need additional adapters, as the power supply includes only one such connector.
Conclusion:The Rosewill Tachyon-550 is a great option for gamers and workstation users who prioritize high efficiency, flexible cable management, and quiet operation within an 80 Platinum certified power supply, despite some limitations on size, modularity, and connector layout.
Recommendation:If you have appropriate case space, would prefer minimal noise, and are dedicated to efficient power usage, the Rosewill Tachyon-550 80 Platinum semi-modular power supply could be an excellent addition to your system build, providing a high level of performance and reliability. However, if you require more extensive modularity options or encounter space constraints, alternative power supplies with more comprehensive modular cable sets or smaller dimensions might be more suitable for your needs.
