Power supply Gigabyte P450B 450W 80+ Bronze PSU

Gigabyte P450B is an ATX power supply with a power of 450W and an 80+ Bronze certification, aimed at budget and mid-range configurations. You get a stable power supply unit with active PFC and efficiency of up to 85%, sufficient for systems with one mid-range GPU and modern CPU. The non-modular design makes it a more affordable solution without sacrificing reliability. The black casing and standard dimensions make it easy to integrate into almost any standard ATX case.

What you get

With 450W real power and Active PFC, you have stable power for gaming or office configuration with one graphics card, without unnecessary noise from straining the PSU under load. The 80+ Bronze certification and up to 85% efficiency mean less heat loss and lower consumption compared to no-name power supplies without certification. With one 120 mm fan, you get adequate cooling at normal noise levels, especially in a well-ventilated case. The rich array of connectors gives you the freedom to power several drives, a more demanding GPU, and additional peripherals without using adapters. The declared MTBF 100,000 hours at 25℃ is a good indicator of expected long life under normal use.

• Power of 450W, suitable for systems with one GPU and modern CPU without the unnecessary risk of power shortage.
• 80+ Bronze certification and up to 85% efficiency for lower power consumption and less heat compared to uncertified PSUs.
• Active PFC for more stable power supply and better power quality, especially important under load and fluctuations in the network.
• 4 x PCI-e 6+2 Pin connectors, providing flexibility for powering more demanding graphics cards or future upgrades.
