TUF-GAMING-550B

The ASUS TUF Gaming 550W Bronze PSU leads in durability.

  • Dual ball fan bearings can last up to twice as long as sleeve bearing designs.
  • A protective PCB coating protects against moisture, dust, and extreme temperatures.
  • Axial-tech fan design features a smaller fan hub that facilitates longer blades and a barrier ring that increases downward air pressure.
  • 0dB technology lets you enjoy light gaming in relative silence.
  • Sleeved cables leave your rig looking tactically clean.
  • 80cm 8-pin CPU connector (EPS 12V)

Dual Ball Fan Bearings

Dual Ball Fan Bearings

2x longer lifespan

Exemplary cooling is provided by a 135mm fan spinning on a dual ball bearing setup that will last up to twice as long as a sleeve bearing design.

Protective PCB Coating

Protective PCB Coating

All wrapped up

A protective conformal coating envelops the PCB to protect against short-circuits caused by moisture, dust, and debris.

Axial−tech Fan Design

Axial−tech Fan Design

Better, faster, stronger

Originally developed for top-end ROG graphics cards, Axial-tech fan design features a smaller fan hub that facilitates longer blades and a barrier ring that increases downward air pressure. For TUF Gaming series PSUs, we've scaled that design to 135mm so it keeps things cool at low RPMs while producing less noise.

0dB Technology

0dB Technology

Quiet intelligence

An onboard controller brings the 135mm fan to a standstill when thermal design power (TDP) is below 30%, letting you enjoy light gaming in relative silence. Above 30% TDP, the fans automatically start up again.

Sleeved Cables

Sleeved Cables

Slim-fit

Cables swathed in black sleeving leave your rig looking tactically clean.
