The ASUS TUF Gaming 550B 550W ATX Bronze Power Supply is a budget-friendly, entry-level power supply designed for users building mid-range gaming PCs or everyday computing systems. It offers 550W of power with 80 PLUS Bronze efficiency, making it a reliable and efficient choice for those looking to power a system without breaking the bank. As part of the TUF Gaming series, it also features military-grade components and robust protection mechanisms, ensuring that it is both durable and reliable for daily use.

Features

1. Power Output (550W):

• The 550W output is ideal for mid-range gaming setups or entry-level PCs, including builds with single GPUs and non-overclocked CPUs.
• Suitable for systems using mid-tier GPUs (e.g., RTX 3060 or GTX 1660) and standard configurations that don’t require excessive wattage.
• Provides sufficient power for typical gaming and office use, making it a great option for users on a budget or those building a compact or minimalist PC.

2. 80 PLUS Bronze Efficiency:

• 80 PLUS Bronze certification ensures that the PSU operates at up to 85% efficiency under typical loads, reducing energy waste and lowering electricity costs compared to lower-efficiency PSUs.
• While it doesn’t offer the highest efficiency like Gold or Platinum rated units, the 80 PLUS Bronze rating is a good balance between cost-effectiveness and energy efficiency for most mainstream PC builds.

3. TUF Military-Grade Components:

• The TUF Gaming 550B incorporates military-grade capacitors and other high-quality components designed to withstand higher temperatures and provide greater durability and reliability.
• These components ensure that the PSU maintains consistent performance and stability over time, even during extended use or under load.

4. Semi-Modular Design:

• Semi-modular cable design allows you to remove unnecessary cables to improve cable management and airflow within the case.
• The 24-pin ATX cable and 4+4 CPU connectors are hardwired, but the rest of the cables (SATA, PCIe) are detachable, which reduces clutter and helps with better system organization.
• This design is a good compromise between full modularity and cost-effectiveness, providing easier cable management than fully non-modular PSUs without the higher price tag of fully modular units.

5. Dual Ball Bearing Fan for Cooling:

• The PSU features a 120mm dual ball bearing fan, which offers quieter operation and improved longevity over sleeve bearing fans.
• Dual ball bearings allow the fan to run more efficiently and last longer, even under heavy loads. This ensures that the PSU stays cool during gaming sessions and that the fan will last longer than traditional fans, improving the overall lifespan of the PSU.

6. Protection Features:

• The TUF Gaming 550B PSU includes a comprehensive range of protections to safeguard your components:
  • Overvoltage Protection (OVP)
  • Undervoltage Protection (UVP)
  • Overcurrent Protection (OCP)
  • Short Circuit Protection (SCP)
  • Over Temperature Protection (OTP)
• These protections ensure that your PSU shuts down safely in the event of any irregularities, preventing damage to your system from electrical faults, power surges, or overheating.

7. Compact ATX Form Factor:

• The TUF Gaming 550B follows the standard ATX form factor, which is compatible with most ATX and mid-tower cases.
• This makes it versatile for different build types, from compact desktop PCs to full-sized ATX systems.

8. TUF Aesthetic Design:

• The PSU features a rugged TUF Gaming design, with a matte black finish and military-inspired branding. This makes it a good match for other TUF Gaming components, such as TUF motherboards, graphics cards, and peripherals.
• The aesthetic design complements both performance-focused and stylish gaming builds.
