ROG Strix 550G Gold Fully Modular PSU from ASUS

ASUS ROG Strix 550 Watt PSU

premium cooling performance to the mainstream The ROG Strix 550 Watt power supply unites high-end cooling and quality components to bring you an ultra-quiet, high-performance product perfect for gaming enthusiasts. Impressive ROG heatsinks are incorporated to keep your PSU performing at it's highest. The 550G also uses ASUS' Axial-tech fan design to make cooling proficient and ensure great operation. Below the surface, low RDS (on) MOFSETs and premium Japanese capacitors take on power delivery easily, with the result being an incredibly quiet and efficient power supply with the power to handle the most intense gaming scenarios.

Enhanced Efficiency Allows the Fan to Keep Things Cool

axial tech fan design

AXIAL-TECH FAN DESIGN Axial-tech fan design was originally the end result of R&D efforts for top-end ROG graphics cards. This innovative design has now been carried over to the PSU to give it the same fantastic performance. It features a smaller fan hub that facilitates longer blades and a barrier ring that works to increase downward air pressure. The enhanced efficiency allows the fan to keep things nicely cooled at low RPMs, resulting in less system noise and increased component lifespan.

Get Twice the Lifespan on your PSU

dual ball fan bearings

DUAL BALL FAN BEARINGS Different PSU bearing types have unique pros and cons. In ROG Strix PSUs, durability is a critical factor, so they feature a dual ball bearing setup which allows it to last up to twice as long as a sleeve bearing design.

Enjoy Gaming in Relative Silence

0db technology

NEAR-SILENT 0DB TECHNOLOGY The ROG Strix PSU features an on-board controller that brings the 135mm fan to a standstill when total draw power (TDP) is below 40%, allowing you to enjoy light gaming in relative silence. When it goes above 40% TDP, the fans will automatically start up again.

Let it Sink in with Twice the Volume

rog heatsinks

EXCLUSIVE ROG HEATSINKS With two times more volume than traditional designs, the integrated ROG heatsinks offer significantly lower temperatures inside Strix PSUs. This improves the longevity of components and allows for 0dB operation for a longer duration than standard designs. The heatsinks are so effective that fan noise will remain whisper quiet, even under demanding loads.

Engineered with a Heart of Gold

80 plus gold

80 PLUS GOLD CERTIFICATION The ROG Strix PSU houses top-end Japanese capacitors that ensure efficient operation and have allowed the Strix to earn an 80 PLUS Gold certification. This increased efficiency also results in less heat, reduced noise and increased reliability.

Simple Cable Management for Neat & Tidy Builds

FULLY MODULAR CABLE DESIGN Keep your system tidier than ever with fully modular cables which come with embedded capacitors to reduce voltage ripple. The included CableMod coupon will set you on your way towards next-level customization.

Change Cosmetics and the Aesthetics of your PSU
