↪ Notes: OCP is not claimed on any rail (although it most likely exists for the minor rails only), very low +12V line output relative to total capacity.
↪ Notes: Overall very low build quality
↪ Notes: "Full Range" version is equally as bad according to the claimed specs.
↪ Notes: Voltage regulation is out of ATX specifications on the minor rails; also not independently regulated.
↪ Notes: Basically Elite V4 but full range
↪ Notes: Complete e-waste. Extremely poor build and component quality all around.
↪ Notes: Grey label
↪ Notes: Grey label; OCP doesn't work properly, allowing the voltages to fall out of spec, very poor ripple suppression on 5V, failed transient testing on 3.3V
↪ Notes: Doesn't claim necessary protections, unknown components such as the capacitors.
↪ Notes: Net graded to Tier E due to it being group regulated.
↪ Notes: Doesn't claim necessary protections, unknown components such as the capacitors.
↪ Notes: Limited information.
↪ Notes: Malfunctioning safety protections that cause the unit to experience catastrophic failure and blow up. Fire hazard.
↪ Notes: No performance data although the platform is decently reviewed.
↪ Notes: Lacks protections, not independently regulated.
↪ Notes: Doesn't claim certain protections, old outdated platform.
↪ Notes: Europe only
↪ Notes: Simplicity HPG, just with a red LED 120mm fan.
↪ Notes: Actual +12V capacity is ~5-10% lower than advertised wattage.
↪ 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: Either dual sourced or XWY replaced HKC.
↪ Notes: Either dual sourced or XWY replaced HKC.
↪ Notes: 3 year warranty, inconclusive on platform until further notice.
↪ Notes: Terrible electrical performance under crossloads (effect of Group Regulation), and overall poor performance otherwise.
↪ Notes: 500W seemingly still manufactured according to MC stock.
↪ Notes: Rebrand of the ST-ES 230V
↪ Notes: Group regulated.
↪ Notes: Under crossload, 5V rail experiences high ripple >100mV, doubling ATX spec.
↪ 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.
