↪ Notes: PPFC; bundled with select Rosewill cases.
↪ Notes: SAMA increased the power-good signal's hold-up time by a lot, which makes this PSU a possible danger to hardware.
↪ Notes: Nearly identical to the XF.
↪ Notes: OCP did work, but the PSU died in the process, which is not ideal. Recommended only for low-end hardware. See testing here.
↪ Notes: Some units produced before 2018 may experience shutdowns with high transient draw GPUs.
↪ Notes: Minor changes with a "V3" model released in 2019.

↪ Notes: White versions of Focus (yes) Gold / Platinum and Prime Titanium.
↪ Notes: Internal shots confirm a costdown Core GC/Focus
↪ Notes: Malfunctioning OTP per Aris' testing
↪ Notes: Costdown of the G12 GC; cheaper components, all Chinese caps, and an even cheaper fan; downgraded to Bronze eff.
↪ Notes: GX but non-modular
↪ Notes: GX but semi-modular
↪ Notes: Sleeve bearing fan, 3.3V rail is subpar in transient testing, fan profile is aggressive and very loud when pushed. Source: Aris
↪ Notes: OTP isn't claimed, IC doesn't support it either
↪ Notes: Semi-modular version of the G12 GC (Global)
↪ Notes: Claims only SCP, OPP, and over/under voltage. OCP not claimed on any rail.
↪ Notes: Not recommended since no proper testing exists, and numerous issues exist with other Segotep units that were tested.
↪ 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: Middling load regulation for the 3.3v & 5VSB rails, 5 year warranty.
↪ Notes: OCP triggering points on the 5V and 5VSB rails allow for excessive ripple beyond the ATX specification. 5 year warranty.
↪ Notes: EU/JP only? No stated manufacturer warranty outside of mandated EU 2 year warranty.

↪ Notes: Only 1650W under 120VAC
Nightjar ATX Titanium
DC-DC
Seasonic
Prime Titanium Fanless
↪ Notes: Fanless
↪ Notes: SX-G upgraded to Platinum efficiency.
↪ 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: Two samples (same platform) no longer operated after protections testing per LTT Labs, which is not ideal, but all protections did function.
↪ Notes: Very poor transient response and ripple on 3.3V.
↪ Notes: Bad power good signal.
↪ Notes: Good electrical performance let down by no inrush protection; bad power good signal.
↪ Notes: 3 year warranty, A+ tier performance.
↪ Notes: Not suitable for use with high ambient temperatures over 40C/~100F, as the fan cannot keep up with the cooling demand.
↪ Notes: Protechnic Electric sleeve bearing fan.
↪ Notes: OTP either set over 200C or not present; extremely loud (over 42dbA) under full load, and mediocre performance all around.
↪ 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: OTP either set over 200C or not present.
↪ Notes: Rebrand of the ST-ES 230V
↪ Notes: Actual 12V capacity is 456W. Does not claim OTP. ARGB fan controlled via motherboard header. Hong Hua rifle bearing fan.
↪ Notes: Several issues including very poor ripple suppression at seemingly random intervals, OCP is set way too high on all rails, bad power good signal.
↪ Notes: Actual 12V capacity is 456W. Does not claim OTP nor OCP. Assumed to be similar to ET500-ARGB.
↪ 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: Hold-up time fails to meet the ATX minimum specification.
↪ Notes: 1200W hold-up time fails to meet the ATX minimum specification.
↪ Notes: 230V only since 115VAC sockets cannot supply 2kW of power.
↪ Notes: Pro version - black casing instead of white. Pigtail PCIe cables for the 650W. Cost down version of the Pro ARGB.
↪ Notes: Poorly tuned OCP & OPP, 20AWG pigtails on PCIe connectors. 750/850w has a dual 8 pin to 600W 12VHPWR cable available for purchase.
↪ Notes: Chinese caps, 20AWG gauges on the EPS/PCIe cables; 5VSB regulation doesn't quite hit A tier specifications.
↪ Notes: Poorly tuned OCP triggering points and 20 gauge wire for the far-end PCIe connectors. Treat capacity as ~100W lower than advertised.
↪ Notes: Unusually tight OCP triggering points and 20 gauge wire for the far-end PCIe connectors. Treat capacity as ~100W lower than advertised.
↪ Notes: 1300W 5VSB voltage regulation doesn't quite hit A tier performance.

Leadex III Super Bronze Pro
DC-DC
Super Flower
Leadex III Bronze (EVGA B3)
↪ Notes: Limited information.
↪ Notes: Leadex II costdown, single-layer PCB. Sleeve bearing fan. Capacitors aren't of the highest quality.
↪ Notes: No OTP and OCP (12V) present; low hold-up time (out of spec); poor soldering quality.
↪ Notes: Sleeve-bearing fan. OCP untested.
↪ Notes: OCP doesn't work properly on +12V, unit experiences a huge voltage drop to 10.92V on +12V. Avoid until further testing.
↪ Notes: 550W tested, 550/650W TGFX ATX 3.0 compliant but no 12VHPWR/12V-2x6. Mediocre ripple & poor inrush current. Cybenetics Platinum/Gold.
↪ Notes: Aggressive fan profile, ~40+ dbA output.
↪ Notes: OTP claimed; tested working in other GPR-based units in similar configurations.
↪ Notes: OPP works, OTP claimed; tested working in other GPR-based units in similar configurations.
↪ Notes: Quite loud under full load, ~39dbA
↪ Notes: 5VSB OCP needs tuning (59mV ripple); An EPS cable can fit into a PCIe socket and vice versa, but they're not electrically compatible.
↪ Notes: Be wary of "2024 Version" 750/850W! Original is 160mm long, "2024" variant is 140mm long
↪ Notes:
↪ Notes: Europe, India and Japan model.
↪ Notes: OTP doesn't work
↪ Notes: OTP is set over 200C or doesn't work.
↪ Notes: No MOV
↪ Notes: Costdown GX1 with 85C Chinese caps and a sleeve bearing Yate Loon fan; intended for OEM/SI market.
↪ Notes: While a functional platform, the other two "known" 750W variants are unidentifiable.
↪ Notes: DC-DC, but 12V capacity is rated awfully low, at what a GR would typically be (672W or 56A).
↪ Notes: Be wary of 2024 CE-Link variant! GX1 costdown. If CWT based, 588W on 12V output for 600W.
↪ Notes: No proper transient testing, too old.
↪ Notes: OTP works on the 1200W model, however the 5VSB OCP is so out of tune, ripple suppression exceeds 100mV.
↪ Notes: 3 separate versions dependent upon region, most groupreg. Also a 230V only version. Essentially unrecommendable due to platform variation.
↪ Notes: Under crossload, 5V rail experiences high ripple >100mV, doubling ATX spec.
↪ 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: 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 safety protections
↪ Notes: Essentially a Thor V2 made for full-modularity; no MOV.
↪ Notes: Poor electrical performance from an unknown OEM; fails all 12V transient response testing per F14 Lab's testing.
↪ Notes: Both the 12V and 3.3V rail fail in ripple measurements, exceeding the ATX specification. No transient response testing.
↪ Notes: Poor electrical performance from an unknown OEM; fails all 12V transient response testing per F14 Lab's testing.
↪ Notes: No OCP, and OVP/UVP is set too high to be effective. Also really only a 600W unit despite being advertised as 750.
↪ Notes: 2 year warranty, sleeve bearing fan. Miserable electrical performance.
↪ Notes: No MOV. OCP on the 3.3V rail failed (via rails falling out of ATX specification)
↪ Notes: Not independently regulated and no 80+ or Cybenetics certification
↪ Notes: Claims to be DC-DC, but internal shots show otherwise; false advertising.
↪ Notes: PPFC and no 80+ certification; e-waste
↪ Notes: Does not claim certain safety protection circuits which is a major deficiency.
↪ Notes: Claimed DC-DC, internal shots from 2023 show otherwise. Confirmed GR.
↪ Notes: Pre production sample used for testing.
↪ Notes: PPFC; e-waste, same as the 83+ XE
