↪ Notes: APFC - no 80 Plus or Cybenetics rating
↪ Notes: PPFC - no 80 Plus or Cybenetics rating
↪ Notes: PPFC on 650W models and below. "Specifications are subject to change at any time without notice."
↪ Notes: PPFC on 650W models and below. "Specifications are subject to change at any time without notice."
↪ Notes: Claims APFC, "90+" badge, extremely low 12V output relative to total, as is per usual for terrible PSUs
↪ Notes: Improperly set OCP allows for abysmal voltage drops past ATX spec.
↪ Notes: No 80 Plus or Cybenetics rating, OCP is not claimed on any rail, poor 12V output relative to total capacity, poor quality fan, etc. Basically e-waste.
↪ Notes: "90% 230V only", claims meeting 80+ Gold without certifying. No direct transient response testing but platform is well reviewed.
↪ Notes: "85% 230V only", ketchup and mustard cables. Outdated and no official 80+ certification, only on the tier list since it's still on their website.

↪ Notes: Yellow on black label; no 80+ certification and aging. Not certain on topology but not recommendable regardless. See review here. No OCP.
↪ Notes: Blue label. No OCP.
↪ Notes: "85% 230V only", ketchup and mustard cables, not independently regulated. Doesn't have OCP according to this review.
↪ Notes: Fake 80+ 230V only certification label, ketchup and mustard cables, not independently regulated. White label. No OCP.
↪ Notes: Fake 85% efficiency label, black on yellow label; it's also old. Not certain on topology but not recommendable regardless. See review here. No OCP.
↪ Notes: Protections don't kick in nearly in time before the voltage on the minor rails falls out of spec under ~108% overload.
↪ Notes: OEM and platform is unconfirmed, unit is basically e-waste though.
↪ Notes: Extremely low 12V line output relative to total claimed capacity, basically only a 350W PSU; no 80+ or Cybenetics rating.
↪ Notes: PPFC, e-waste, only rated for a continuous operating temperature of 25C.
↪ Notes: Malfunctioning safety protections (OCP/OPP) allowing for OOS operation and catastrophic failure, 20AWG PCIe.
↪ Notes: Initial batches of the unit were shipped without the OCP chip, supposedly newer batches have this new fuse chip but yet confirmed.
↪ Notes: PPFC, extremely poor build quality and component quality; e-waste.
↪ Notes: PPFC, extremely poor build quality and component quality; e-waste.
↪ Notes: Doesn't claim necessary protections. No real 80+ certification label on the unit.
↪ Notes: No OCP, faulty UVP on 3.3V, bad electrical performance.
↪ Notes: PPFC; bundled with select Rosewill cases.
↪ Notes: Lacks proper OCP. Allows for huge voltage drops out of ATX spec resulting in UVP kicking in.
↪ Notes: Lacks proper OCP. Allows for huge voltage drops out of ATX spec resulting in UVP kicking in.
↪ Notes: Unknown number of suppliers. Missing crucial safety protections, very old platforms and very poor build quality.
↪ Notes: Missing crucial safety protections, very old platform and very poor build quality.
↪ Notes: Not independently regulated and no 80+ or Cybenetics certification
↪ Notes: PPFC and no 80+ certification; e-waste
↪ Notes: PPFC; e-waste, same as the 83+ XE
