ASUS ROG Thor 1200W Platinum III

1200W ATX 3.180 PLUS PlatinumGaN MOSFETOLED + Aura ARGB

The ASUS ROG Thor 1200W Platinum III (ROG-THOR-1200P3-GAMING) is a flagship fully modular 1200-watt ATX 3.1 power supply with 80 PLUS Platinum efficiency, built for premium high-end and enthusiast gaming PCs. Carrying the part number 90YE00V2-B0NA00, it pairs a native PCIe 5.1 12V-2x6 connector with cutting-edge GaN MOSFETs, a “GPU-First” voltage stabilizer, a swappable magnetic OLED power-draw display and Aura Sync ARGB lighting. A Cybenetics A++ noise rating, 0dB fan mode and 10-year warranty mark it out as a true halo product. Typically in stock with fast delivery across Cyprus.

Compatibility & fit
Includes a native PCIe Gen5.1 12V-2x6 cable (16-pin) for RTX 50-series and other next-gen GPUs, plus four PCIe 6+2 connectors. The magnetic OLED display can be mounted on either side of the PSU. Note the longer 190mm body — confirm your case supports a 190mm-deep PSU. ARGB and OLED connect via the included cables; full-range 100–240V input runs natively on Cyprus 230V mains.

Best For

✓Flagship gaming PCs with RTX 4090 / 5090-class GPUs
✓Showcase builds wanting OLED power display and ARGB
✓PCIe 5.1 systems needing a native 12V-2x6 connector
✓Enthusiasts who want the best efficiency and acoustics
✓Silent builds (0dB fan mode, Cybenetics A++ noise)
✓Premium long-life rigs backed by a 10-year warranty

Key Features

 
GaN MOSFET efficiency
Gallium-nitride MOSFETs deliver up to 30% more power efficiency than standard MOSFETs, enabling 80 PLUS Platinum performance in a cooler, denser design.
 
GPU-First voltage stabilizer
A patented intelligent voltage stabilizer prioritises and enhances voltage delivery to your graphics card by up to 45% for rock-steady high-end GPU performance.
 
Magnetic OLED power display
A swappable magnetic OLED screen shows real-time power draw and can be mounted on either side of the PSU to face your case window.
 
0dB silence + Aura Sync ARGB
A Cybenetics A++ noise rating with a 0dB fan button keeps the fan off at low load, while Aura Sync addressable RGB ties the lighting into your build.

Frequently Asked Questions

Does the ROG Thor 1200P3 work with an RTX 50-series GPU?
Yes. It ships with a native PCIe Gen5.1 12V-2x6 (16-pin) cable for RTX 50-series and other next-generation graphics cards, plus four PCIe 6+2 connectors for additional or older cards.
What does the OLED display show?
It shows your system’s real-time power draw in watts. The display is magnetic and can be detached and re-mounted on either side of the PSU so it always faces your case window.
How quiet is the ROG Thor 1200P3?
Extremely quiet. It earns a Cybenetics A++ noise rating and features a 0dB fan button — with it on, the fan stays completely off until the system reaches a certain load.
What makes the Platinum III different from older ROG Thor units?
The Platinum III adds ATX 3.1 with a native 12V-2x6 connector, new GaN MOSFETs for higher efficiency, and the GPU-First voltage stabilizer — all while keeping the signature OLED display and Aura Sync lighting.
Singular Expert Insight
The ROG Thor Platinum III sits at the very top of ASUS’s PSU range — a showcase unit that combines Genuinely advanced engineering (GaN MOSFETs, GPU-First voltage stabilization, Cybenetics A++ acoustics) with the OLED display and Aura Sync lighting enthusiasts love. It is overkill for a budget build, but for a flagship RTX 4090/5090-class system it is one of the most complete PC power supplies money can buy. If you want the same Platinum platform without ARGB and the OLED, the ASUS ROG Strix Platinum is a more restrained alternative.

Buyer’s Guide

Buy it if
You want a flagship 1200W ATX 3.1 PSU with native 12V-2x6, GaN efficiency, near-silent acoustics, an OLED power display and Aura Sync ARGB.
Skip it if
You are on a budget or do not need the OLED display and ARGB — a plainer Platinum or Gold unit will power the same system for less.
Also consider
The ROG Thor 1200P3 White Edition to match a light build, or the ASUS ROG Strix Platinum for a similar platform without the OLED/ARGB premium.
