ASUS PRIME 550W - PSU, 80 Plus Bronze

The ASUS PRIME 550W Bronze is a desktop power supply designed to deliver continuous power to a general-purpose computer. Its continuous output is rated at 550 W, providing the main figure for assessing the system’s component demand. The 80 PLUS Bronze certification indicates improved energy efficiency compared with a basic uncertified supply. This classification relates to electricity lost as heat during AC-to-DC conversion, although no exact efficiency percentage is specified. The output class is intended for everyday computing, productivity, gaming and general-purpose graphics hardware, subject to the total requirements of the selected components.

The unit’s fixed cable layout means every power lead remains attached to the housing, so unused cables must stay inside the case. This removes detachable cable interfaces but places more emphasis on cable routing during installation. Cable selection cannot be changed by swapping in a different set of detachable leads. No specified noise rating or fan-speed range is supplied, so these characteristics cannot be compared from the available figures. It is intended for desktop builds and upgrades where rated output and required connections have been checked in advance.
