Gigabyte P450B 450W ATX Power Supply – 80 Plus Bronze

The Gigabyte P450B is a 450W ATX desktop power supply unit built for reliable, efficient performance. Its 80 Plus Bronze certification delivers up to 85% efficiency at 50% load, meaning less energy wasted as heat and a quieter system overall — a practical advantage for any desktop PC build.

Quiet, efficient power with cleaner cable management

• 450W output with a single +12V rail for straightforward compatibility and stable power delivery to your components
• 80 Plus Bronze efficiency reduces heat output and lowers fan noise compared to uncertified units
• 120mm hydraulic bearing fan adjusts speed automatically based on load, keeping noise levels low during light use
• Flat ribbon cables reduce interior clutter and help maintain better airflow inside the case
• Multiple protections including OVP, OPP, SCP, UVP, OCP and OTP guard your hardware against electrical faults

The P450B suits budget-conscious home and office desktop builds, compact mid-tower setups, and anyone upgrading an ageing power supply unit without overcomplicating cable routing.
