Revision 16.1A
Last Update: 03-10-2022

Legend
Green highlight - Small form-factor units
Gold highlight - Best units in the tier. High quality and performance proven by professional reviews. Requires 16AWG wire gauge in pig-tailed cables and quiet operation under reasonable load levels for tier A.
Blue highlight - Quiet operation under moderate load

Hyphen / Dash - Series / lineups separator
Slash - Models (inside one series) separator
Underlined - Opens menu with more information and links to Amazon
Parenthesis / Round brackets - Model variations (which belong to the same position)
Square brackets - Additional description (wattage range, part of SKU code, label / casing color, release year)
Numbers in red colored square brackets - Footnotes, see descriptions at the end of respective tiers

Low priority subtiers - Units with minor issues (see footnotes). Not recommended for purchase over any normal priority units.
Speculative position subtiers - For units positioned based on limited info, but enough to reasonably assume that they're very similar to other units there are proper reviews on. Not recommended for purchase over any normal priority units or even some of the better units from a lower tier.
Multi-rail units - Not necessarily better than single-rail units but provide an extra layer of protection by having 12V OCP set lower than total capacity, which is especially relevant for very high-capacity units (=>1kW). Pay attention to rails configuration when using with high power draw components to avoid shutdowns.

Tiering Methodology

Tier requirements:

Tier A - required to be based on ZVS primary topology (LLC or phase shift resonant), have ripple below 50mV under all load situations up-to 110% overload, <=3% transient response on 12V rail, <=3% 12v voltage deviation from nominal. Fan with =>30k hours MTBF at 40°C (generally non-plain-sleeve bearing) or be fanless. All capacitors rated for 105°C. Minimum 18AWG gauge wires for hot 12V leads on GPU/EPS/ATX cables, on pig-tail cables - at least to the first connector, 20AWG to the second or for ground leads.
Requires reviews with transient response and protection tests (OCP, OPP, OTP) either on the unit directly for normal priority or other unit using the same platform in similiar configuration which is confirmed by a teardown for speculative position subtier.

Tier B and above - required to have OTP (just claimed is enough), be based on ACRF or ZVS primary, DC-DC secondary topology, and have APFC with full VAC input range; voltage regulation and ripple should be in spec under 110% overload; 12V ripple below 100mV under 110% overload on all rails; should be rated for continuous operation at minimum 40°C ambient (not just 'operating conditions' but unless proven to not qualify by testing, only claimed operating conditions without continous operation remark is enough)

Tier C and above - required to have independent regulation on all rails and/or <5% min to max voltage regulation on all rails under extreme crossloads and high combined load; ripple on 12V rail should be below 100mV under extreme crossload and high combined load situations and up-to 100% load.

Tier D and above - required to have OPP claimed; requires OCP on minor rails tested, SCP on all rails tested, UVP, OVP on all rails claimed (or a teardown showing that supervisor IC supports that), ripple within specs, voltage regulation in specs on all rails under moderate crossloads and 100% load, all tests directly on the unit; units failing any single of aforementioned requirements are moved to low priority subtier, or to lower tiers if issues are multiple or severe

Tier E - units expected to be qualifying for no higher than tier D but without reviews or reliable information on, or otherwise having characteristics or issues keeping them from being placed on the same tier as better tier D units, or otherwise, units there are too little information on to be reliably tiered

Tier F - heavily malfunctioning protections, QC issues or design flaws leading to widespread malfunctions / DoAs

Low priority subtiersUnits there are no direct proper reviews on but enough info to otherwise speculatively tier them to one tier or another.

Speculative position subtiers - Units there are no direct proper reviews on but enough info to otherwise speculatively tier them to one tier or another.

Highlight colors definition:

Green - Small form factor PSUs - SFX, SFX-L, TFX. Highest priority color, i.e SFF units aren't marked by gold or blue colors.

Gold - Best units in the tier, requirements (in addition to the requirements for tiers themselves) :

for tier A : <=1.5% 12V peak to peak, <=2% transient response on 12V rail, <=3% deviation from nominal 5V rail, <=30mV max ripple on the 12v rail(s) including 110% load tests, transient response within ATX spec on 5V rail. Minimum 1/2/3 total 8-pin PCIe connectors for <=550W/650W-750W/=>850W units respectively with minimum 16AWG to the first connector and 18AWG wire gauge to the second connector on 12V leads for pig-tailed PCIe/EPS cables in case there aren't enough single-ended cables.
Includes requirements for blue color (quiet operation).

for tiers C & B : <=3% 12V deviation from nominal, <=75mV max ripple on 12V rail.
Quiet operation (blue color requirements) is not required.

Blue - Quiet operation. No bearing / switching noise. Sub 30 dBa under moderate load i.e 300W at 12V rail for <=500W units, 400W for 501-749W units, 500W for =>750W units (30-50W load on minor rails). Additionally, for tier A units, sub 35 dBa under 70% load for =>850W units (30-50W load on minor rails), and sub 20 dBa under low load (idle), i.e 100W at 12V rail and 15-20W load on minor rails.
Stock or after manual configuration using software or fan mode switch button.

White - Default color

[1] Units experiencing tripping issues with high transient power draw GPUs like AMD Vega, 6900 XT and Nvidia RTX3080/3090. Generally fixed in newer batches.
[2] Corsair SF units with LOT codes from 194448* through 201148* have potential problems, Corsair conducts a voluntary replacement, source.
[3] Lower than 18AWG wires in pig-tail end of PCIe/EPS cables for 12V leads, don’t use for constant high-load applications or only use the first connector.
[4] Antec EA Pro Gold has versions for Chinese market made by FSP on completely different, worse, group-regulated platform (tier E). Source #1, #2.
[5] Issues around high OTP, not shutting down at 200c (heatgun), but working afterwards
[6] Leadex V series has 20AWG wires in pig-tail cables and lower than 105% OPP, making it potentially susceptible to tripping with high-end, high transient power draw GPUs.
[7] Older Seasonic Focus revisions (Focus Gold, Focus Plus Gold / Platinum, made before 2018) had transient sensitivity issues. Some more recent models are not affected because they were released after the fix (Seasonic Focus GM/GX/PX refreshes, Phanteks AMP, NZXT C/E etc.). Although situation with Ampere GPUs is unclear it’s assumed that there are no widespread issues on Focus platform.
[8] Seasonic PRIME based units experience shutdowns with RTX3080/3090 (and possibly RX6900 XT) GPUs. The cause is not the OCP tripping but a PSU design flaw as evident by the PSU not latching off on shutdown and 1000W+ models being affected too. Doesn’t manifest in 100% cases as it’s also dependent on motherboard model and GPU OC. Seasonic provides a new 24-pin cable to fix this via support.
[9] There are regional (China and Australia) versions of AX1600i with C14 socket instead of C20 and with no mention of sub 200V input voltage operation. They’re still identical to worldwide versions otherwise and such can be used under full 100-240V input voltage range but maximum operating wattage under low input mains voltage is limited by the lower current and temperature rating of C14 socket, it’s not recommended to use such units at higher than 1.3kW capacity in 120V mains or lower due to risk of melting the socket.
[10] Out of production, any listings you would encounter today would be either used, refurbished or at the very least being long in storage. Buy at your discretion.
[11] Ball bearing fan, possibly not silent even at very low RPMs.
[12] PCIe and EPS modular sockets aren’t electrically compatible despite they are mechanically, pay attention, misconnecting might result in the damage to PC.
[13] Be aware that strictly multi-rail units (without a possibility to switch to single-rail mode) can trip with very high power draw GPUs (RTX3080/RX6800XT and higher) and/or CPUs (unlocked Intel i7/i9 or AMD Threadripper) due to lower OCP tripping point when the load on rails is unbalanced. Read the manual and balance out the load if that happens.

[1] Seasonic S12II Bronze and related units have or had UVP issues, source.
[2] Seasonic S12III, S12II EVO and A12 – OCP (on any rails) not claimed, nor present in supervisor IC. No reviews with protection tests to prove otherwise.
[3] Antec EA Pro Gold has versions for Chinese market made by FSP on completely different, worse, group-regulated platform (tier E). Source #1, #2.
[4] Issues around a non-functional OTP and OCP reported by Poiu @ TweakPC

[1] Very high DOA rate and underrated FETs that explode under high stress. Sources : #1, #2, #3, #4. There’s a claimed fix, and some units made after early 2021 seem to be good but it’s not clear to which extent the issue was fixed and past what manufacturing date non-fixed revision wouldn’t be encountered anymore.
[2] Downgraded 230V-only version of S12III platform.
[3] OCP either not present on any rails or faulty/unreliable. No reviews with protection tests to prove otherwise.
[4] Sources : EVGA W1, N1
[5] Source : Armageddon Voltron, other offerings are assumed to perform on the same level until proven otherwise
[6] Review sample manipulation / post review design downgrades / frequent component changes without significant differences in branding / paid reviews
