Platform
↪ Notes: Insane 7 year warranty given the component quality, OCP is set way higher than necessary on the minor rails, very poor 200% excursion response.
↪ Notes: Though a sleeve bearing fan is used, 1st Player backs it up with a 7-year warranty.
↪ Notes: Although OCP is set reasonably (118% on 12V), the platform is at its limit and cannot handle the increased stress, as ripple gets out of control.
↪ Notes: Shares the same layout as the Lian Li SP850, which, due to its capacity and layout, had a potential fire risk under 100VAC input.
↪ Notes: Costdown Core Reactor II
↪ Notes: ATX 3.0 refresh
↪ Notes: The OCP trggering point for the 5VSB line allows for extremely excessive ripple. 12V line voltage ripple spikes around the 80-90% load range.
↪ Notes: Read note regarding input range. Despite markings on the DC-DC daughterboard indicating CWT GPU, internal shots confirm CWT GPX.
↪ Notes: Read note regarding input range. Mid quality fan; Same Martech "FDB" fan on the MSI A-GL series.
↪ Notes: No OTP claimed
↪ Notes: No OTP claimed
↪ Notes: Claims APFC, "90+" badge, extremely low 12V output relative to total, as is per usual for terrible PSUs
High Current Gamer (HCG) Gold
DC-DC
Seasonic
Focus Gold

↪ Notes: 650W has poor 3.3V transient response
↪ Notes: 5VSB OCP set high, poor 3.3V transient response in the 200% excursion
↪ Notes: 2 year warranty; No OTP claimed, but platform is otherwise reasonably capable.
↪ Notes: 2 year warranty; platform is otherwise reasonably capable.
↪ Notes: Bridgeless PFC, OCP needs tuning on all rails

↪ Notes: One review had 12V line voltage deviating slightly more than the limit in the 160% ATX 3.1 excursion test. OCP, OPP, and OVP are set too high on all rails.
↪ Notes: One EPS cable shares the same 12V rail with a PCIe cable, low hold up time, transient on the 3.3V rail/OPP needs tuning.
↪ Notes: Very high inrush current, poorly tuned protections on the minor rails; otherwise decent electrical performance.
↪ Notes: 850W model can come in white.

↪ Notes:
↪ Notes: Europe, India and Japan model.
↪ Notes: Be wary of 2024 OEM/Platform change in the N.A. market!
↪ Notes: Unnanounced OEM swap. Technically invalid 80 Plus certification, but did qualify for Gold in testing, as advertised.
↪ Notes: Single-sided PCB, voltage drops right before protection trip points on the minor rails; however, the protections did engage in time.
↪ Notes: OTP doesn't work
↪ Notes: OTP is set over 200C or doesn't work.
↪ Notes: No MOV
↪ Notes: Transient response was tested but values were left out. OPP is set very high, but the PSU handled it and shut down safely and properly.

↪ Notes: Multiple inexcusable protections malfunctions despite good electrical performance.
↪ Notes: BE WARY OF ATX 3.1 2024 VARIANT! Poor transient response on 3.3V and load regulation on 5VSB. Very good electrical performance otherwise.
↪ Notes: The OCP and OPP triggering points are set much higher than necessary.
↪ Notes: Advertised as ATX 3.1. Platform has poor transient response in 200% ATX 3.1 test, weak 3.3V load regulation, and high-set OCP on the minor rails.
↪ Notes: Mediocre transient response on the minor rails. The OPP and OCP triggering points should be reduced, as they are set way higher than necessary.
