Product Features
Built around a 450W ATX design, this power supply is made to keep a full PC running stably under different conditions. Using a single +12V rail helps deliver consistent power output with strong compatibility for connected hardware. Installation stays straightforward, making it easier to route power where you need it. Protection designs including OCP, OTP, OVP, OPP, UVP and SCP help keep the system operating safely.
With 80 Plus Bronze certification, power delivery is designed to be more efficient during typical use. Hitting 85% efficiency at typical load means less wasted power, which can translate into less heat inside the case. Lower heat output also helps reduce how hard the cooling needs to work. That combination supports a quieter and more comfortable everyday PC experience.
Cooling is handled by a 120mm Silent Hydraulic Bearing (HYB) fan that focuses on noise reduction and thermal performance. Fan speed adjusts according to automatic power detection, so it responds to what your system is doing. The hydraulic bearing design is intended to provide a longer and more stable lifetime. This helps keep airflow steady while maintaining a quieter build.
Reliable flat cables are designed to make system building cleaner and easier. Flat, all-black cabling reduces clutter, which can improve airflow through the case. Better airflow can help other components stay cooler during use. Cable routing also looks tidier, especially in windowed cases.
