POWERFUL CONNECTIONS
With three EPS12V connectors and fully modular cabling, HXi Series platinum power supplies have every connection needed to power today’s most demanding PC upgrades now and into the future, including the latest generation of power-hungry graphics cards and processors.

ATX 3.1 CERTIFIED
The ATX 3.1 standard demands a high level of reliability and power efficiency. While many CORSAIR PSUs meet these requirements, HXi Series PSUs are formally certified for ATX 3.1 compliance.

PCIe 5.1 12V-2x6 GPU cable included for use with modern graphics cards such as the NVIDIA® GeForce RTX™ 40 Series.

QUIET OPERATION
HXi Series PSUs combine a 140mm fluid dynamic bearing fan with Zero RPM mode support for long-lasting fan performance and near-silent operation when the fan switches off at low and medium loads – only spinning as fast as it needs to.

UNWAVERING POWER AND QUALITY
80 PLUS Platinum certified with premium 100% Japanese 105°C electrolytic capacitors, HXi PSUs ensure up to 92% efficiency for exceptional power delivery and long-term reliability with low power consumption, less noise, and cooler temperatures.

POWER AT THE READY
As a fully digital power supply, each HXi Series PSU provides clean, consistent power while minimizing coil whine and noise for stable and quiet operation.

Supporting Modern Standby sleep mode, the HXi Series takes low-load efficiency to the next level with quiet operation and extremely fast wake-from-sleep times.

80 PLUS PLATINUM CERTIFIED
Steady power output at up to 92% efficiency, and Cybenetics-certified for lower power consumption, less noise, and cooler temperatures.

105°C-RATED CAPACITORS
Built with 100% Industrial-grade, 105°C-rated Japanese primary electrolytic capacitors for unwavering power and reliability.

YOUR SETUP AT YOUR COMMAND
With CORSAIR iCUE software, you can monitor your power supply performance, toggle single rail or multi rail mode, and control fan speed directly from your desktop.

WORLD-CLASS SUPPORT
Our award-winning service means you can enjoy your gear worry-free.

ROG Loki 1000W Platinum
The Quietest SFX-L PSU
Taking after the ROG Thor, the ROG Loki SFX-L 1000W Platinum brandishes the same enthusiast-grade components and features, all packed into an SFX-L form factor. Boasting quiet operation and high performance, the Loki is primed to power your next SFF build.

ROG Heatsinks
Cool under pressure
ROG heatsinks facilitate lower temperatures, longer component lifespan, and extended 0dB operation.

80 PLUS Platinum Certified
Effortless output
Low-ESR Japanese capacitors further improve efficiency and reduce heat, readying ROG Loki to reliably fuel your build for years to come.

ATX 3.0 Compatible
Step into the future
The latest power specification updates have landed. ATX 3.0 ushers in tighter voltage and current regulation guidelines for next-gen hardware - and ROG Loki steps ahead of the curve by being fully compliant. A 16-pin PCIe cable ripe for piping up to 600W of power to PCIe Gen 5.0 graphics cards is bundled with the PSU, bringing large-scale capabilities to SFF rigs.

ARGB-illuminated Fan & Aura Sync
Magical glow
The Loki's 120 mm fan features eight addressable LEDs ready to be customized with Aura Sync to create coordinated lighting patterns across your build.

* If the connector cable is not used, the default color effect is rainbow.
* To enjoy Aura Sync, you’ll need an Aura Sync-compatible ASUS or ROG motherboard. Similarly, the Smart Mode lighting effect, which reflects GPU temperature, requires use of a compatible ASUS or ROG graphics card.

COOLING

ROG Heatsinks
Cool under pressure
ROG heatsinks facilitate lower temperatures, longer component lifespan, and extended 0dB operation.

Axial-tech Fan Design
Better, faster, stronger
Axial-tech fan design features a smaller fan hub that facilitates longer blades and a barrier ring that increases downward air pressure. For ROG Loki PSUs, we've scaled that design to 120mm so it keeps things cool at low RPMs while producing less noise.

Dual Ball Fan Bearings
2x longer lifespan
The fan impeller spins on a dual ball bearing setup that will last up to twice as long as a sleeve bearing design.

0dB Technology
Quiet intelligence
To reduce noise output, the PWM-controlled fan shuts off entirely when the PSU load is 40% or below.

Lambda A Certification
Quietly deviant
On average, ROG Loki emits less than 25 dB of noise – earning a coveted Cybenetics Lambda A certification.
