Rosewill Photon-1000 Review
Looking for a 1000W Platinum power supply from a value-focused brand rather than a premium name, the Rosewill Photon-1000 undercuts most Platinum-rated 1000W units on price while still backing it with a 10-year warranty.
We think this is a legitimately good deal for high-end single-GPU or light multi-GPU builds: Platinum efficiency and full modularity at a price closer to Gold-tier competitors. It's a less common name than Corsair or Seasonic, so expect a shorter track record of long-term reliability data.
Value at the Platinum Tier
Rosewill positions the Photon line as a value alternative to premium Platinum units from bigger brands, using a Sirfa-built platform that hits the efficiency numbers without the marketing budget baked into the price.
Comparison to Alternatives
Against the Corsair HX1000i already in the catalog, the Photon-1000 gives up digital rail monitoring and brand pedigree in exchange for a notably lower price at the same 1000W Platinum tier. Against the Seasonic Prime 1000 Platinum, the Photon-1000 undercuts on price while matching the wattage and efficiency rating, though Seasonic's in-house build has a longer reliability track record.
