Asus TUF Gaming 450B 450W Power Supply, 80Plus Bronze, PSU, PCI-E 6+2-pin x2, Fan Size 135mm | 90YE00D3-B0NA00

Military-Grade Durability and Protection

The TUF Gaming 450B is engineered to survive where others might fail. Critical components, including capacitors and chokes, pass demanding tests to achieve Military-grade Certification, ensuring stable operation under heavy stress. To further enhance its "TUF" credentials, the internal circuit board is shielded by a protective PCB coating. This conformal coating guards against short circuits caused by moisture, dust, and debris, making it an ideal choice for challenging environments or long-term system longevity.

Advanced Axial-tech Cooling

Borrowing high-end thermal technology from top-tier ROG graphics cards, the TUF Gaming 450B features an Axial-tech fan design. This setup utilizes a smaller hub to allow for longer blades and a barrier ring that increases downward air pressure, moving more air through the components without increasing noise. Combined with dual ball fan bearings, which can last up to twice as long as standard sleeve bearing designs, the cooling system is as durable as the power delivery itself.

Silent Performance with 0dB Technology

For those who appreciate a quiet workspace, this PSU features 0dB technology. An intelligent onboard controller brings the 135mm fan to a complete standstill when the total power draw (TDP) is below $30\%$, allowing you to enjoy light gaming, web browsing, or office work in absolute silence. Once the load increases, the fan automatically ramps up to keep the hardware cool.

Tactical Aesthetic and Ease of Build

The TUF Gaming 450B doesn't just act tough; it looks the part. It features sleeved cables that provide a "tactically clean" look to your interior while making cable management easier. A standout feature for modern chassis is the 80cm 8-pin CPU connector (EPS 12V), providing extra length to ensure you can route power to the top of the motherboard in large cases without tension or the need for extensions.
