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 very limited info, without proper reviews. Not recommended for purchase over any normal priority units or even some of the better units from a lower tier.
Multi-rail units - Offer better protection against inadvertent cable overload (which is especially relevant for high-capacity units) but can be problematic when used with very high transient power draw GPUs. Pay attention to rails configuration in the PSU manual to balance out the load.

Tiering Methodology

Tier requirements:

Tier A - OTP should be tested (if not tested - detier to SP subtier), working and set below 200°C (if it's set higher - detier to LP subtier), 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. ATX 3.0 subsection requires an Intel DB entry or third party power excustion tests.

Tier B and above - required to have OTP (just claimed is enough, but if it's tested and the unit did not survive - detier to LP subtier), to have OPP tested (detier to tier C if failed), be based on ACRF or ZVS primary, DC-DC secondary topology, and have APFC with full VAC input range (100-230V); voltage regulation and ripple should be in spec under 110% overload; 12V ripple below 100mV under 110% overload; 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.

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

There's one allowed test point out of tier requirements for ripple, load regulation or transient response without detiering.

Normal priority subtier - direct reviews with transient response and protection tests (OCP, OPP, plus OTP for tier A), and sufficient for tier B and lower - only a teardown confirming highly similiar component choices

Low priority subtiers - direct reviews without protection tests (for tier B and lower) or due to minor issues with the tests

Speculative position subtiers - units with barely sufficient info on. Meaning at least primary and secondary topology is known. But tier A requries either a full teardown to confirm high similiarity with the unit from normal priority or a Cybenetics report available.

Highlight colors definition:

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. One exclusion allowed for test data point outside of required range. Minimum 18AWG cable gauge for hot 12V leads. Includes requirements for blue color (quiet operation).
Includes requirements for blue color (quiet operation).

for tiers C & B : mostly based on review availability, objective quality and performance compared to competition in the same tier to highlight the most important models in respective price ranges

Blue - Quiet operation, meaning sub 30 dBa (35 dBa for SFX units) under moderate load i.e :

- 300W at 12V rail for <=500W units

- 400W for 550-700W units

- 500W for =>750W units (30-50W load on minor rails).

Additionally, for tier A units, sub 35 dBa (45 dBa for SFX units) 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.

Colors priority : Gold > Blue

[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] OTP is set too high or potentially non-functioning, unit survived the test, source : Aris (HWBusters / TPU / THW) reviews.
[3] An ATX 3.0 PSU which doesn’t include a 12VHPWR cable out of the box (yet). Buy separately as needed.
[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] Non-functioning multi-rail OCP essentially making it a single-rail PSU.
[6] Leadex V series has 1) OCP set to 100.8% of nominal capacity, i.e lacking the headroom for transients when most high-end PSUs have it set in the range of 120-140%. So for example a 1kW version of it more like 750-850W in comparison with competition. 2) 20AWG cables past the first PCIe connector, which is against ATX spec.
[7] Bitfenix Whisper M and Formula Gold 450/550W units have just one ‘GPU’ rail with 30A OCP limit, but it is possible to plug PCIe cable into the same socket as for EPS rail, thus using two rails if the unit shuts down with high power draw GPUs.
[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 replacement 24-pin ATX cable to fix this via support. Appears to be fixed post 2021 although there’s no official confirmation from Seasonic.
[9] Due to regional regulations (China and Australia) there’s version of AX1600i with C14 receptacle instead of C20, with no mention of sub 200V input voltage operation on the label. The PSU itself is still identical to the worldwide version otherwise, and as 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 load under 120V input voltage or lower due to the risk of melting the receptacle.
[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 (>400W) and/or CPUs (unlocked Intel i7/i9) due to lower OCP tripping point. Read the manual and balance out the load if that happens.
[14] Potential ATX 3.0 units either not tested for compatibility (no Aris review), not received the certification (no entry in Intel’s DB), having problems with passing ATX 3.0 tests (failed Aris review), or without proper reviews in the first place to put them in the normal priority subtier.
[15] Most good 1-1.2kW+ non-ATX 3.0 PSUs would work with GPUs utilizing ATX 3.0 transient power draw spec due to enough headroom for transients.
[16] The PSU-side 12VHPWR receptacle is not a requirement for an ATX 3.0 PSU. The additional 4-pin part of it is passive, with no ‘communication’, they’re simply shorted to ground which can be made in-cable. And since a single 8-pin PCIe cable can withstand ~342W the worst case scenario (per-pin current capacity is the same as with 12VHPWR), such cable with 2×8-pin connectors PSU-side is even safer than one with 12VHPWR on both ends due to more thermal headroom.

[2] High wattage (=>750W) CWT GPX based units have problems with failing burn-in test under sub 100VAC input, don’t use in countries with sub 115VAC mains (JonnyGURU).
[4] Two versions of Segotep GP-G exist, older v1 version is non-LLC resonant.
[5] Units with 230V only input voltage range
[6] Out of production, any listings you would encounter today would either be used, refurbished or at the very least being long in storage. Buy at your discretion.
[7] Early models\wattages of Gigabyte P-GM had massive QC issues, see footnote for tier F entry. 1000W SKU is more recent and assumed to be fixed from the start, although there are no reviews to confirm that so buy at your discretion.
[8] Malfunctioning protections, source.

[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.

[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
