↪ 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: "Full Range" version is equally as bad according to the claimed specs.

↪ 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: PPFC

↪ 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: PPFC; e-waste

↪ 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: Doesn't claim 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: Complete e-waste. Extremely poor build and component quality all around.

↪ Notes: Extremely low 12V line output relative to total claimed capacity, basically only a 350W PSU; no 80+ or Cybenetics rating.

↪ Notes: Supremo Gold made for non-modularity. No OCP to be found in testing nor claimed.

↪ Notes: PPFC, e-waste, only rated for a continuous operating temperature of 25C.

↪ Notes: Malfunctioning safety protections that cause the unit to experience catastrophic failure and blow up. Fire hazard.

↪ 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: Lacks protections, not independently regulated.

↪ Notes: Doesn't claim certain protections, old outdated platform.

↪ Notes: Malfunctioning OCP and OPP on +12V line (voltage out of spec), poor transient response on minor rails, failed to meet 80+ Gold rating.

↪ Notes: PPFC, extremely poor build quality and component quality; e-waste.

↪ Notes: PPFC, extremely poor build quality and component quality; e-waste.

↪ Notes: Widespread failures due to explosive FETs from bad board design. See serial number range in notes for affected units.

↪ Notes: Doesn't claim necessary protections. No real 80+ certification label on the unit.

↪ Notes: OCP on both the 3.3V and 5V lines is either faulty or set in excess of 330%, which is unacceptable. Bad electrical performance (severely OOS).

↪ Notes: Doesn't claim SCP according to this review.

↪ Notes: Malfunctioning OCP on 3.3V, and transient response on 3.3V is out of spec, questionable choices of components.

↪ Notes: Extremely low 12V line output relative to total capacity. The "1000W" model has only 750W available to the +12V line.

↪ Notes: Extremely low 12V line output relative to total capacity. The "1000W" model has only 750W available to the +12V line.

↪ Notes: Fatal design flaw that causes an X cap to melt under 100VAC; potential fire hazard. Two samples also died during LTT Labs testing.

↪ Notes: Extremely poor electrical performance which leads to severe out of ATX compliance, very abnormal implementation. Refer to here.

↪ Notes: 130mV+ of ripple on all rails (out of spec) at only 60% load; failed to meet even 80+ Bronze. See Rear Shot and Output Specification Label.

↪ Notes: No OCP, faulty UVP on 3.3V, bad electrical performance.

↪ Notes: Terrible electrical performance under crossloads (effect of Group Regulation), and overall poor performance otherwise.

↪ Notes: PPFC; e-waste

↪ Notes: Low quality sleeve bearing fan, ripple exceeds ATX specification, low quality capacitors, and a 3 year warranty.

↪ Notes: PPFC; bundled with select Rosewill cases.

↪ Notes: Claims only SCP, OPP, and over/under voltage. OCP not claimed on any rail.

↪ Notes: Lacks proper OCP. Allows for huge voltage drops out of ATX spec resulting in UVP kicking in.

↪ Notes: EPS cable melted during efficiency testing, so protections were not tested. Possible bad sample. Avoid until further notice. No claimed OTP.

↪ Notes: Lacks proper OCP. Allows for huge voltage drops out of ATX spec resulting in UVP kicking in.

↪ Notes: Numerous protections malfunctions and terrible electrical performance. See testing here.

↪ Notes: Actual 12V capacity is 456W. Does not claim OTP nor OCP. Assumed to be similar to ET500-ARGB.

↪ Notes: Does not claim OCP on any rails. Minimal information available.

↪ Notes: Numerous issues capped off by malfunctioning OPP that either doesn't exist or is set way too high, which caused the unit to explode.

↪ Notes: Malfunctioning OCP and OPP that fails to kick in before the unit's line voltages drop out of spec.

↪ Notes: OCP doesn't work properly on +12V, unit experiences a huge voltage drop to 10.92V on +12V. Avoid until further testing.

↪ Notes: Unknown number of suppliers. Missing crucial safety protections, very old platforms and very poor build quality.

↪ Notes: Very poor build quality and unknown number of suppliers, crucial protections not claimed.

↪ Notes: Black casing, white sticker. Unknown number of suppliers for this unit. Versions that have been tested have malfunctioning OCP, OPP, and SCP.

↪ Notes: Multiple inexcusable protections malfunctions despite good electrical performance.

↪ Notes: Missing crucial safety protections, very old platform and very poor build quality.

↪ 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: Malfunctioning protections that don't engage in time before the minor rails experience a huge voltage drop out of spec.
