↪ Notes: A few samples of the base platform died when subjected to sub-90VAC stress tests per JonnyGuru. Proceed with caution under 120VAC, especially in areas prone to brownouts.

↪ Notes: Both EPS connectors share a cable, poor regulation and transient response on minor rails; only a 2 year warranty.

↪ Notes: Platform is somewhat mediocre, no direct transient response testing available and not the best choice of capacitors.

↪ Notes: "90% 230V only", claims meeting 80+ Gold without certifying. No direct transient response testing but platform is well reviewed.

↪ Notes: Receives a "-" subtier due to its age. Only kept for legacy purposes as it is still listed on Chieftec's website.

↪ 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 Outdated and no official 80+ certification, only on the tier list since it's still on their website.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: Electrical performance is decent (although no transient response data) but simply not recommendable due to age.

↪ 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 Outdated and no official 80+ certification, only on the tier list since it's still on their website.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: Protections don't kick in nearly in time before the voltage on the minor rails falls out of spec under ~108% overload.

↪ Notes: Same internals as the Plus Platinum without the screen, ARGB fan, or digital control.

↪ Notes: Built-in screen, ARGB fan, and digital fan control and monitoring via MasterPlus software.

↪ Notes: Platform is essentially a modified MWE Bronze V3.

↪ Notes: Basically G1208 updated to ATX 3.1

↪ Notes: Modified MWE Bronze V3, same as G Gold V2.

↪ Notes: Very similar to the GX III that superseded it.

↪ Notes: GX III ATX 3.0, but upd. to ATX 3.1. Yate Loon rifle-bearing. Has purple heatsinks for glam.

↪ Notes: Basically G1208 updated to ATX 3.1, no 12VHPWR.

↪ Notes: v1, 160mm long

↪ Notes: 160mm length, Sunon Magnetic Levitation (Maglev) bearing fan.

↪ Notes: Grey label; RM-x v1 with digital monitoring features

↪ Notes: Technically 80+ Silver without RGB on

↪ Notes: Gray label; toggleable per-cable OCP.

↪ Notes: Gray label. Custom Corsair rifle bearing fan.

↪ Notes: 650W has 300W 12V-2x6 cable. Poor 3.3V transient response. All use Hong Hua rifle-bearing fans. Y-shaped fan grille perforations.

↪ Notes: Grey label; costdown RM-x. Out-of-spec 3.3V transients. Hong Hua rifle bearing fan. Meets all other tier A requirements.

↪ Notes: Triangular fan grille perforations. Hong Hua rifle bearing fan. Performance is assumed to be the same as 2019 version.

↪ Notes: 140mm long. Same design as the 2023 RMe, without an included 12VHPWR cable.

↪ Notes: Gray label

↪ Notes: White "CX" lettering on black label; Identical to the CV aside from exterior design.

↪ 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: Costdown GX-F

↪ Notes: Mediocre quality capacitors.

↪ 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: Platform is certified for Gold, might have only hit Bronze due to modular interface

↪ 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: Can come in white variants. Mediocre fan, no SCP on -12V rail, which isn't used in modern PCs. Avoid if using very old hardware.

↪ Notes: Subpar component quality, with poorly tuned protections, 5V OCP incorrectly set allows for >135mV of ripple. OOS 3.3V transient response.

↪ Notes: Doesn't claim necessary protections, unknown components.

↪ Notes: Net graded to Tier E due to it being group regulated.

↪ Notes: Platform visually appears identical to the 916MC platform used in the SAMA XF, which died during OCP testing per LTT Labs. Proceed with caution.

↪ Notes: Good electrical performance for the category, decent component quality, protections are set reasonably.

↪ Notes: Supremo Gold made for full-modularity, necessary protections aren't claimed.

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

↪ Notes: Ripple on 12V was shown at 52mV, all other requirements for tier A proper are met.

↪ Notes: Decent electrical performance let down by poor transient response, a sleeve bearing fan, and other miscellaneous problems.

↪ Notes: Decent overall performance despite being ACRF on the primary side, double ball bearing fan.

↪ Notes: See notes under Series name for how to identify each version.

↪ Notes: PWR_OK signal doesn't function correctly. Poor transient response on the minor rails.

↪ Notes: OCP on 12V doesnt exist. OPP is set too high. Sleeve bearing fan.

↪ Notes: Malfunctioning safety protections (OCP/OPP) allowing for OOS operation and catastrophic failure, 20AWG PCIe.

↪ Notes: Fails EMI testing, 2 EPS connectors on one cable, minor rails are either failing or near failing with regards to transient response.

↪ Notes: PWR_OK signal testing failed; mediocre load regulation and transient response on the minor rails.

↪ Notes: Good electrical performance, but lacks or has improperly tuned OTP. No 12VHPWR.

↪ Notes: Strong electrical performance (A tier), but with less expensive components and a rifle bearing fan.

↪ Notes: Not enough conclusive data but platform is well reviewed.

↪ Notes: No performance data although the platform is decently reviewed.

↪ Notes: Sleeve bearing fan.

↪ Notes: Traditional thin circular fan grille.

↪ Notes: Uses hexagonal (in a circular shape) and oblong fan grilles.

↪ Notes: Sleeve bearing fan.

↪ Notes: No OTP claimed.

↪ Notes: The OCP triggering points on the minor rails should be reduced. Some components, especially on the secondary side, are of questionable quality.

↪ 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: OTP is claimed but has been hit-or-miss on NO-810 units and not present on the P125. Tier is based on other NO-810 units until tested.

↪ Notes: Same design as the OEM HP1-J-GD-F12S with a rifle bearing fan.

↪ Notes: Included with the InWin A1 Plus case; not available on its own.

↪ Notes: Actual +12V capacity is ~5-10% lower than advertised wattage.

↪ Notes: Two samples no longer operated after protections testing per LTT Labs, which is not ideal, but all protections did function.

↪ Notes: Multi-rail functionality effectively negated by per-rail 12V OCP being set especially high. OPP is still functional.

↪ Notes: Minor rails' OCP is set lower compared to the CWT-built high-wattage models. 650W is noisier than the 750W on account of using a DBB fan.

↪ Notes: Semi-modular A-BN. See internal shots here.

↪ Notes: Components are variable based on batch.

↪ Notes: Components are variable based on batch.

↪ Notes: Single-rail. See review. Poor transient response on 3.3V, rifle bearing fan. OTP isn't claimed or tested, but is supported by the supervisor IC.

↪ 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: Added MCU and secondary supervisor IC.

↪ Notes: Fan grille without island about the fan hub. 140mm fan

↪ Notes: Fan grille with islands above the fan hub and for fan mounting holes. 120mm fan

↪ Notes: White 750W available.

↪ Notes: 500W seemingly still manufactured according to MC stock.

↪ Notes: Still produced according to MC stock

↪ Notes: Still produced according to MC stock

↪ Notes: Some degree of false advertising going on. Claims to be LLC resonant with an FDB fan and 105C caps. Internal shots show otherwise. Recommended to proceed with caution. Even though the platform is safe, it's not as good as advertised.

↪ Notes: PPFC; e-waste

↪ Notes: 1 year warranty according to manufacturer, at least in Russia, which appears to be the main target market for this unit.

↪ Notes: Internal shots show the unit using the same "ICB" (in reality rifle bearing) fan as the SilverStone Triton Rx.

↪ Notes: Mediocre load regulation on the minor rails, and poor excursion response in the 200% test. The OCP and OPP triggering points are set too high on all rails. 1000W model has high inrush currents. Good performance otherwise.

↪ Notes: Electrical performance is mediocre and OCP triggering points are sky high. Recommended only for low-end hardware.

↪ Notes: SFX-L
