↪ Notes: Unnanounced OEM swap. Technically invalid 80 Plus certification, but did qualify for Gold in testing, as advertised.
↪ Notes: OTP is set over 200C or doesn't work.
↪ Notes: Limited special edition model for 25th anniversary, no indication of any internal changes

NO-819C
↪ Notes: Very beefy platform, however OTP doesn't work; very loud. Would be tier A- if not for OTP not working.
↪ Notes: Costdown GX1 with 85C Chinese caps and a sleeve bearing Yate Loon fan; intended for OEM/SI market.
↪ Notes: Poor thermal management; fan has to work very hard to prevent OTP from kicking in. Can get as loud as ~60dbA (!) under high operating temps.
↪ Notes: Be wary of 2024 CE-Link variant! GX1 costdown. If CWT based, 588W on 12V output for 600W.
↪ Notes: Multiple inexcusable protections malfunctions despite good electrical performance.
↪ Notes: Over 500mV of ripple at 110% load on the +12V line is inexcusable (over 4x the ATX specification limit). Clearly a major design flaw.
↪ 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.
↪ Notes: Overall really good electrical performance with only the 3.3V rail trailing behind in transients and failing testing. OTP isn't tested.
↪ Notes: Both the 12V and 3.3V rail fail in ripple measurements, exceeding the ATX specification. No transient response testing.
↪ Notes: Does not claim certain safety protection circuits which is a major deficiency.
↪ Notes: 1000W has very poor transient response in the 200% ATX 3.1 excursion test, poor regulation on 3.3V, OCP is set way too high on the minor rails.
