Corsair Power Supplies

↪ Notes: Braided cables, some units manufactured between Oct. 2019 to Mar. 2020 (lot codes 194448xx to 201148xx) recalled for potential failures.

↪ Notes: Standard cables

↪ Notes: v2, 160mm long, doesn't have 1000W version; custom Corsair rifle bearing fan.

↪ Notes: v1, 160mm long

↪ Notes: Blue label. Tiering is based on electrical performance and should not preclude the usual caveats if buying used power supplies.

↪ Notes: v1, 180mm long

↪ Notes: v1, 180mm long, individually sleeved cables; custom Corsair rifle bearing fan.

↪ Notes: v2, 160mm long; custom Corsair rifle bearing fan.

↪ Notes: v1, 180mm long. Production continued far past other 2015 RM-x units as the 2018 revision has no 1kW variant.

↪ Notes: Grey label; RM-x v1 with digital monitoring features

↪ Notes: 160mm length

↪ Notes: Semi-digital. Good noise profile. 5VSB OCP is set quite high. Look above for case clearance list.

↪ Notes: Class-leading performance, excellent build quality, relatively quiet for the capacity.

↪ Notes: Grey label; potential issues with heavy transient loads.

↪ Notes: Black label, triangle fan grille. Digital monitoring and semi-passive operation controlled via USB-C connector in software.

↪ Notes: Refresh with included 12V-2x6 cable and listed ATX 3.1 compliance. Actual design appears to be the same internally.

↪ Notes: 10th anniversary limited run, only 100 units with white casing & white LEDs inside.

↪ Notes: 180mm length, Sunon Magnetic Levitation (Maglev) bearing fan.

↪ Notes: Gray label. Per-connector 40A OCP when multi rail is enabled

↪ Notes: Refresh with included 12V-2x6 cable and listed ATX 3.1 compliance. Actual design appears to be the same internally.

↪ Notes: Minor changes on the primary side, overall very similar; merely a refresh. Embossed cables instead of flat cables from older generations. (Fancy)

↪ Notes: Technically 80+ Silver without RGB on

↪ Notes: Gray label; toggleable per-cable OCP.

↪ Notes: Black label; China only

↪ Notes: Poor ripple suppression on the minor rails. Uses semi-digital PFC, 7 year warranty. Can get loud (in excess of 40dbA) under heavy load.

↪ Notes: SI model for Chinese market

↪ Notes: Gray label. Custom Corsair rifle bearing fan.

↪ Notes: Gray label. Custom Corsair rifle bearing fan.

↪ Notes: 650W has 300W 12V-2x6 cable. Poor 3.3V transient response. All use Hong Hua rifle-bearing fans. Y-shaped fan grille perforations.

↪ Notes: Grey label; costdown RM-x. Out-of-spec 3.3V transients. Hong Hua rifle bearing fan. Meets all other tier A requirements.

↪ Notes: Triangular fan grille perforations. Hong Hua rifle bearing fan. Performance is assumed to be the same as 2019 version.

↪ Notes: 140mm long. Same design as the 2023 RMe, without an included 12VHPWR cable.

↪ Notes: 750/850W: 140mm, 1000/1200W: 150mm. 2023 version includes 12VHPWR cable. Early reports of coil whine and premature failures/DOAs, but supposedly fixed.
