The GIGABYTE P450B is a reliable, simple and affordable power supply for mainstream PC and office setups. Ideal for users who don't need high-end gaming performance and appreciate simple installation with flat cables and basic component protection.
450 W power - suitable for office, multimedia and less demanding gaming setups.
80 PLUS Bronze certification - up to 88% efficiency at half load, less heat and lower consumption.
Standard ATX format - compatible with most cases.
Flat wiring - easy installation and better airflow in the cabinet.
120mm long life fan (100,000 h) - efficient cooling.
No modular cabling - multiple cables inside can make space management and editing difficult.
Power 450 W - suitable only for less demanding gaming setups, for more powerful graphics cards may not be enough.
80 PLUS Bronze - still solid, but not as effective as the Silver/Gold variants.

I bought it for an old comp because the old power supply went out. The new one works, but the fan is surprisingly noisy.
The source, as such, works.
Surprisingly noisy fan even at minimum load
