How each alternative compares

EVGA Supernova 1000 P2 Platinum Power Supply

The EVGA Supernova 1000 P2 offers 1000W of 80 Plus Platinum efficiency, which is 200W less than the Thor 1200W. It uses a standard ATX form factor measuring 7.8 inches long, slightly longer than the Thor’s 7.4-inch chassis. This unit is fully modular and includes Japanese capacitors for stable power delivery. It carries a 10-year warranty, matching the Thor’s coverage. You should choose this if your system does not require the full 1200W capacity.

ASUS ROG Loki 850W SFX-L Platinum PSU

The ASUS ROG Loki 850W SFX-L provides 850W of 80 Plus Platinum efficiency, which is 350W less than the Thor. It uses a compact SFX-L form factor, measuring only 4.9 inches in length, making it much smaller than the Thor’s 7.4-inch ATX chassis.

The ASUS ROG Strix 1200W Platinum matches the Thor’s 1200W output and 80 Plus Platinum efficiency rating. It supports ATX 3.1 standards and is fully modular. Its chassis is 6.3 inches long, which is shorter than the Thor’s 7.4-inch design. This unit carries a 10-year warranty. You should consider this if you want the same wattage but prefer a more compact footprint. It provides clean power for high-end graphics hardware in a slightly smaller ATX case. It is an excellent alternative for users who need 1200W but have less vertical space available.

ASUS ROG Strix 1000W Platinum White

The ASUS ROG Strix 1000W Platinum White offers 1000W of 80 Plus Platinum efficiency, which is 200W less than the Thor. It supports ATX 3.1 standards and is fully modular.
