ASUS ROG Thor 1000W Platinum III PSU - ATX 3.1, GaN MOSFET
The ASUS ROG Thor 1000W Platinum III PSU is a high-output ATX 3.1 power supply built for enthusiast and high-performance PC builders who need rock-solid voltage stability under heavy, sustained loads. It combines GaN MOSFET technology, a patented "GPU-First" intelligent voltage stabilizer, and a magnetic OLED display showing real-time power draw, making it a well-instrumented choice for demanding builds centred on the latest graphics cards.
Why this product
GaN MOSFET for greater power efficiency
GaN MOSFET technology delivers up to 30% more power efficiency than standard MOSFETs and enables a more organised internal layout that supports cooler operation.
GPU-First voltage stabilizer
A patented intelligent voltage stabilizer prioritises the graphics card rail, enhancing voltage delivery to the GPU by up to 45% for more stable performance during demanding workloads.
Magnetic OLED display
A repositionable magnetic OLED panel shows real-time power draw and can be moved to either side of the unit to suit fan-up or fan-down PSU orientations.
ATX 3.1 and PCIe 5.1 compatible
Full ATX 3.1 compliance ensures tighter voltage and current regulation for next-generation hardware, and a bundled 16-pin PCIe cable supports up to 600W delivery to PCIe 5.1 graphics cards.
Dual certifications: 80 PLUS and Cybenetics Platinum
It holds both 80 PLUS Platinum and Cybenetics Platinum ratings, plus Lambda A++ certification for noise levels certified below 15 dB.
10-year warranty included
A 10-year warranty is included, reflecting confidence in the dual-ball-bearing fan and fully aluminium enclosure built to last.

- EAN4711387610596
- Fully compliant with the ATX 3.1 standard for enhanced voltage and current regulation.
- Compatible with PCIe 5.1 graphics cards; a 16-pin PCIe cable capable of delivering up to 600W is included.
- Confirmed compatible with GeForce RTX 50 and Radeon RX 9000 series graphics cards.
- Accepts a wide AC input range of 100–240 V, making it suitable for use in most regions worldwide.
- The OLED display is magnetic and repositionable, but physical clearance inside the case should be verified before choosing fan-up or fan-down orientation.
- Not a SFX or SFX-L form factor unit; dimensions are 190 × 150 × 86 mm, so it will not fit cases designed only for small-form-factor PSUs.
Best for
- High-end gaming builds running the latest GeForce RTX 50 or Radeon RX 9000 series GPUs that need stable, prioritised voltage delivery under sustained load.
- Builders who value instrumentation — the real-time OLED power draw display helps monitor system consumption without third-party software.
- Quiet computing environments where noise matters — Lambda A++ certification confirms noise levels below 15 dB.
- Long-term builds where the 10-year warranty and dual-ball-bearing fan longevity (rated up to twice the lifespan of sleeve bearing designs) reduce the risk of having to replace the PSU mid-cycle.
- Modular cable routing is aided by etched, pliable modular cables designed to lie flat and simplify cable management.
Trade-offs
- Small-form-factor builds — at 190 × 150 × 86 mm this is a full-size ATX PSU and will not fit SFX or SFX-L cases.
- Budget-conscious builders who do not need features like GaN MOSFETs, an OLED display, or the GPU-First voltage stabilizer and would be better served by a simpler certified unit.
- Workloads requiring more than 1000W total output — the combined +12V rail is rated at 1000W and cannot be exceeded.
- Older non-modular PSU chassis builds — this is a fully modular unit and requires a compatible ATX case that can accommodate its cable connectors and 190 mm depth.
