↪ Notes: Much better performance than the 1200W model and fewer issues despite using the same platform.

↪ Notes: Ball bearing fan. No warranty period mentioned, detier to B-.

↪ Notes: Bridgeless PFC, OCP needs tuning on all rails

↪ Notes: Bridgeless PFC, very high component and build quality. OCP needs tuning on all rails. Excellent noise profile.

↪ Notes: First be quiet! PSU with semi-passive operation.

↪ Notes: OPP is functional but offers only a 7% increase over the nominal value, beyond which the rails fall out of ATX spec for the 1000W model.

↪ 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. Production continued far past other 2015 RM-x units as the 2018 revision has no 1kW variant.

↪ Notes: 180mm length, Sunon Magnetic Levitation (Maglev) 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: 750/850W: 140mm, 1000/1200W: 150mm. 2023 version includes 12VHPWR cable. Early reports of coil whine and premature failures/DOAs, but supposedly fixed.

↪ Notes:

↪ Notes: The OCP and OPP triggering points are set too high on all rails, especially 5VSB, where it allows for extremely excessive ripple. Good noise profile.

↪ Notes: Very high inrush current, poorly tuned protections on the minor rails; otherwise decent electrical performance.

↪ Notes: Protections need tuning, 5VSB regulation doesn't quite qualify for A tier.

↪ Notes: 850W model can come in white.

↪ Notes: Semi-digital. Outstanding performance per Aris' review.

↪ Notes: Platform visually appears identical to the 916MC platform used in the SAMA XF, which died during OCP testing per LTT Labs. Proceed with caution.

↪ Notes: No performance data, however platform is well reviewed with protections working in similar configs.

↪ Notes: Old but gold (no pun intended.)

↪ Notes: High RMA rate due to MLCC cracks, similar to other HEC-built EVGA PSUs. Showed up on B-Stock in huge quantities for dirt cheap c. 2022.
