Thor vs Strix 1200W Specs

Physical dimensions

Edge: ASUS ROG Strix 1200W Platinum PSU

The ASUS ROG Thor measures 7.4 inches in length, 5.9 inches in width, and 3.3 inches in height. It weighs 11 pounds. The ASUS ROG Strix 1200W is shorter at 6.3 inches long, with the same 5.9-inch width but a slightly taller profile of 3.4 inches. The Strix does not list a weight in the provided data. If your case has tight clearances for power supply length, the Strix offers a more compact footprint. The Thor is deeper, which might matter in smaller chassis. You should measure your specific case before deciding.

ATX version

Edge: ASUS ROG Strix 1200W Platinum PSU

The ASUS ROG Strix 1200W explicitly supports the ATX 3.1 standard. This version ensures native compatibility with the latest graphics cards and power requirements. The ASUS ROG Thor 1200W Platinum II does not list its ATX version in the provided specifications. While it is a high-end unit, knowing the exact standard helps ensure future-proofing for newer components. If you are building with the very latest hardware, the Strix’s stated ATX 3.1 support is a clear advantage. You should verify if the Thor meets your specific motherboard requirements separately.

Fan size

Edge: ASUS ROG Thor 1200W Platinum II

The ASUS ROG Thor 1200W Platinum II features a large 135mm PWM fan. Larger fans generally move more air at lower speeds, which can reduce noise. The ASUS ROG Strix 1200W uses a dual ball fan bearing design, but the specific fan diameter is not listed in the data. Dual ball bearings often last longer than sleeve bearings, as noted in the Strix features. Without the Strix fan size, we cannot directly compare airflow potential. The Thor’s large fan is a distinct spec for cooling performance.

Internal technology

Edge: ASUS ROG Strix 1200W Platinum PSU

The ASUS ROG Strix 1200W utilizes GaN MOSFET technology. This delivers superior power efficiency by up to 30% and allows for a more organized internal layout for cooler operation. It also features GPU-first voltage sensing with a patented intelligent voltage stabilizer to enhance voltage delivery. The ASUS ROG Thor 1200W Platinum II does not list these specific internal technologies in the provided data. The Strix highlights these features for better thermal management and stability. This gives the Strix an edge in modern component efficiency.

Efficiency and warranty

Edge: Tie

Both power supplies offer 80 Plus Platinum efficiency ratings. They also both come with a 10-year warranty. The ASUS ROG Thor is Lambda A++ Certified, which indicates high reliability and performance standards. The ASUS ROG Strix 1200W does not mention Lambda certification in the provided data. Since both share the same efficiency tier and warranty length, this category is a tie for basic specs. The Thor’s additional certification is a positive note, but the core metrics are identical.

Which ASUS 1200W PSU fits you

Users needing the shortest power supply

Our pick: ASUS ROG Strix 1200W Platinum PSU

The ASUS ROG Strix measures 6.3 inches in length, making it significantly shorter than the Thor’s 7.4-inch chassis. This compact form factor helps fit into smaller cases or improves cable management. Both units share the same width and height, but the Strix saves valuable space inside your build without sacrificing the 1200W output you require.

Gamers wanting GPU voltage stability

Our pick: ASUS ROG Strix 1200W Platinum PSU

The ROG Strix includes patented intelligent voltage stabilization that enhances voltage delivery to your graphics card by up to 45%. This GPU-first sensing ensures smoother gameplay and unwavering performance during intense loads. If you prioritize stable power delivery to your GPU above all else, the Strix’s specialized voltage management offers a clear technical advantage over the Thor.

Enthusiasts preferring larger fan cooling

Our pick: ASUS ROG Thor 1200W Platinum II

The ASUS ROG Thor features a 135mm PWM fan, which is larger than the standard fans found in many competitors. Larger fans can move more air at lower speeds, potentially reducing noise. If you value the specific acoustic profile and airflow characteristics of a 135mm fan, the Thor’s cooling solution offers a distinct mechanical difference compared to the Strix.
