[1] Units experiencing tripping issues with high transient power draw GPUs like AMD Vega, 6900 XT and Nvidia RTX3080/3090.
[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] Corsair HX1200 and HX1200i units with LOT codes in range between 2030* and 2041* may exhibit motherboard compatibility issues, entitled for advanced RMA, source.
[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. A DIY fix is possible, of disconnecting a specific pin on the PSU-side of connector 24-pin motherboard cable. Sub 850W Prime GX/PX models are not affected since they’re based on Focus platform. There’s no public information from Seasonic on the issue and whether it was fixed but it was confirmed by JonnyGURU to be present at least in late 2020 revision units and there are user reports with units past this date.
[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.

[2] High wattage (=>750W) CWT GPX based units have problems with failing burn-in test under sub 100VAC input, treat as 230V only (JonnyGURU).
[3] Units experiencing tripping issues with high transient power draw GPUs like AMD Vega and high-end Nvidia Ampere.
[4] Two versions of Segotep GP-G exist, older v1 version is non-LLC resonant and they’re very hard to extinguish externally, hence model tiering based on v1.
[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.

- Corsair AX1600i

One of a kind PSU on the market, state-of-art technology, GaN semiconductors, totem-pole APFC, all-digital control circuits, PC interface to control and monitor the PSU, fantastic performance in all aspects, made by an enterprise-scale OEM - Flextronics. But all that also comes with a very expensive price tag, so it's not for everyone. Although if you just need the best PSU out there and don't care about the price - look no further.

Buy 1600W

Pros :

• Top-notch performance
• Very quiet up to 1.2kW load
• State-of-art technology
• Corsair iCUE interface
• Configurable per-connector multi-rail OCP
• A lot of single-ended GPU cables

Cons :

• Very expensive
• Only two EPS cables, connectors
• In-cable capacitors can be hard to work around

- BeQuiet Dark Power Pro 12

While most be quiet! PSUs are made by FSP, and while robustly built, perform somewhat lacking to competition, this CWT made model is not only the best offering out of be quiet! lineup, but also one of the best PSUs on the market.

Buy 1200W 1500W

Pros :

• Top of the line performance
• Very quiet up to 1kW load
• Multi-rail, switchable to single-rail mode
• All PCIe cables are essentially single-ended

Cons :

• While cheaper than AXi, still very expensive

- Corsair HX

Corsair's second best offering and one of the best PSUs overall. Your best bet if you need a 1/1.2kW PSU.

Buy 750W 850W 1000W 1200W

Pros :

• Very robust build quality
• Multi-rail, switchable to single-rail mode
• Very quiet even at high load

Cons :

• Rather large
• In-cable capacitors may be hard to work around

- Enermax Revolution DF

Not the best Enermax's offering on paper, but despite that, one of the best value yet very high quality PSUs on the market.

Buy 650W 750W 850W

Pros :

• High quality and performance
• Very quiet
• Higher cable gauge than competition at this price range
• Ribbon cables

Cons :

• Warranty period is shorter than competition
• Somewhat lacking reviews (but based on a proven platform by CWT)
• Strictly multi-rail, which may be problematic with high power draw GPUs

- Adata XPG Core Reactor

ADATA's first venture in the PSU market proven to be a total win. They've chosen CWT as an OEM and requested not an off-the-shelf platform which CWT has a lot of good ones, but a custom one, resulting in even higher performance.

Buy 650W 750W 850W

Pros :

• Often one of cheapest PSUs in our best picks for tier A
• High build quality and higher than competition cable gauge
• Relatively quiet

Cons :

• Lacks semi-passive mode (but still quiet at idle)

- Adata XPG Cybercore

After the success of Core Reactor series, ADATA decided to spice up a PSU market a little employing a 'name' brand fan manufacturer for this series.

Buy 1000W 1300W

Pros :

• A fan from Nidec, essentially being a PSU version of acclaimed Gentle Typhoon
• Very high quality and performance
• Relatively quiet for the wattage capacity
• Very compact for capacity

Cons :

• The fan is 120mm since Nidec doesn't make a 140mm one which would've fit this PSU better
• Ball bearing fan, which may emit characteristic rustling/ticking sound even at very low RPM

- Cooler Master V Gold V2

Cooler Master has a long history of PSUs, not all of which were very successful, but this series has proven itself to be very solid, despite, or maybe because they're working together very closely in an almost exclusive relationship with Gospower, a rather uknown but experienced OEM.

Black color :

White color :

Buy 550W 650W 750W 850W

Pros :

• High build quality and performance
• High cable gauge
• Quiet

Cons :

• Somewhat unknown OEM, which yet was able to build a very high quality product

- Corsair RMx 2018

Corsair's best value offering, a very high-end PSU, borderlining 'best on the market', at least at this price range.

Note: there's no 1kW version of 2018' revision, 2015' one is still in production instead, performance and quality is comparable.

Black version :

Buy 550W 650W 750W 850W 1000W

White version :

750W 850W

Pros :

• Very quiet
• Very high build quality and performance
• White version has ribbon cables and no in-cable caps, both versions are 16AWG
• 1kW version is more robustly built than competition (but longer)

Cons :

• Cables might be hard to work with due to in-cable capacitors (not in white version)

- Corsair RMx 2021

A refresh of the acclaimed series with the 'name'-brand fan manufacturer.

Buy 550W 650W 750W 850W 1000W

Pros :

• Sunon Maglev fan
• Exact same and very high performance / build quality as on 2018' version
• 1kW version is more robustly built than competition (but longer)

Cons :

• Somewhat more expensive than 2018' version despite questionable advantages of Maglev fan over cheaper but still very high quality Hong Hua FDB they could've used
• In-cable capacitors may be hard to work with
• Somewhat less quiet at high-load than 2018' version, still reasonable for the load level and compared to competition

- Corsair RM 2019 / 2021

Corsair's attempt to make an acclaimed RMx series cheaper, successful in a sense that quality was not sacrificed as capacitors are still very high quality, but not Japanese branded as some people might prefer at this price point.

Note: Most 'Japanese' capacitors you'll see in consumer PSUs today are actually of Chinese origin due to better supply chain, made on the same factories as some 'Chinese' brands and will have very similar characteristics to some models of non-Japanese capacitors, so the advantage of 'Japanese' branded capacitors in a consumer mass-produced PSU is debatable.

2019 version :

2021 version, black color :

Buy 650W 750W 850W

2021 version, white color :

Buy 750W 850W

Pros :

• Despite non-'Japanese' branding, capacitors and the build overall are still very high quality just as with parent series
• No in-cable capacitors compared to RMx

Cons :

• Most of the time not as cheap as people would expect a PSU with 'non-Japanese' capacitors to be

- EVGA G6 / P6

The best Seasonic-made PSU on the market, ironically not sold by Seasonic themselves. Better built than Focus GX, comparable to competition like Corsair RM/RMx.

80+ Gold :

Buy 650W 750W 850W 1000W

80+ Platinum :

Buy 650W 750W 850W 1000W

Pros :

• 16AWG cables in 850/1000W
• Very quiet and high build quality
• Very compact at 140mm deep
• Ribbon cables
• One of the most compact 1kW PSUs

Cons :

• 1kW version is probably a bit too compact for the power density
• 18AWG in pig-tailed cables in sub 850W models (doesn't qualify for gold color in tier A)
• 80+ Platinum version isn't really any better than 80+ Gold one, not worth paying more for

- EVGA P2 / T2

This series is why EVGA PSUs are so popular today despite their lineup overall is a mixed bag. Made by Super Flower, essentially Super Flower Leadex Platinum / Titanium under EVGA's label. Very robustly built (even compared to Super Flower's own Leadex V sadly). Reliability is proven by miners using this series all around the world with great success.

80+ Platinum :

Buy 650W 750W 850W 1000W 1200W 1600W

80+ Titanium :

Buy 850W 1000W 1600W

Pros :

• T2 is very quiet
• Very robustly built, high quality and performance

Cons :

• P2 is not as quiet as one would expect a modern high quality PSU to be (which is why it's not marked as gold/blue color)
• Ball bearing fan may emit characteristic rustling/clicking noise even at low RPMs
• 1.2kW+ is too high for comfort on a single-rail, multi-rail is preferred at this capacity
• 80+ Titanium version might be too expensive to be a good pick

- MSI A1000G

MSI's first 1kW PSU. Made by CWT on a relatively new platform which appears to perform relatively good and the build quality is good too but there are better 1kW PSUs like Corsair RMx and EVGA P2 / SF Leadex P.

Buy 1000W

Pros :

• Compact
• Good performance and quality
• Relatively quiet

Cons :

• Relatively new platform with no proven track record (but reviews are good and the OEM is very experienced)

- Silverstone DA1650G

Silverstone highest capacity offering. While not as robust as Corsair, be quiet!, EVGA and Super Flower offerings, made by High Power, it performed very well in reviews and has good enough build quality to recommend it as sort of budget alternative to more expensive 1.6kW PSUs, provided it's cheap enough to qualify as such.

Buy 1650W

Pros :

• Good quality and overall performance

Cons :

• Not really all that cheap compared to better alternatives most of the time
• An OEM which isn't really known for very high-end PSUs
• Noisy at high load
• 1.6kW is too high for comfort on a single-rail, multi-rail is preferred at this capacity

- Superflower Leadex Platinum SE / Titanium

Super Flower is an OEM behind highly acclaimed EVGA G2, G3, P2, T2 series, the latter two of which are EVGA branded variants of the models in question. Very robustly built and proven reliability, unlike cheaper Leadex III and V series there are better alternatives from competition on the market.

80+ Platinum

Buy 1000W

80+ Titanium

Buy 750W 850W 1600W

Pros :

• Very robust build quality
• 80+ Titanium one is quiet, and 'Special Edition' versio nof 80+ Platinum one is supposed to be too

Cons :

• Almost non-existent in most countries (as an alternative, EVGA P2 / T2 are essentially the same thing)
• No reviews on 'Special Edition' revision which is supposed to be quieter than the OG one
• Ball bearing fan may emit rustling / ticking sound even at low RPMs
• 1.2kW+ is too high for comfort on a single-rail, multi-rail is preferred at this capacity
• 80+ Titanium version might be too expensive to be a good pick

- Thermaltake Toughpower TF1

Thermaltake PSU lineup might be a mixed bag with series using different OEMs seemingly at random and built with different quality level. But this one is the best Thermaltake PSU period, made on a very high-end platform from CWT.

Buy 1550W

Pros :

• Very high quality and performance, mostly uncharacteristic of Thermaltake PSUs
• Relatively quiet

Cons :

• 1.2kW+ is too high for comfort on a single-rail, multi-rail is preferred at this capacity
• Expensive

- Thermaltake iRGB Plus Platinum

Another of the very few actually good Thermaltake PSUs, made by very experienced OEM - CWT, and very is robust. This is probably the best RGB PSU on the market.

Buy 850W 1050W 1250W

Pros :

• RGB
• Very high quality and performance
• Quiet

Cons :

• RGB
• Might not make sense to buy price-wise unless you need a RGB PSU as there are better or comparable but cheaper options

- Corsair SF

Best SFX PSU on the market period.

80+ Gold :

Buy 450W 600W

80+ Platinum :

Buy 450W 600W 750W

Pros :

• 80+ Platinum version is quieter than even some ATX PSUs of higher capacity
• Still unmatched for true SFX PSUs, very high quality and performance
• 80+ Platinum version comes with braided 'custom' cables and an ATX adapter bracket
• 750W version is enough for pretty much any build it makes sense to build in an ITX case

Cons :

• 80+ Gold version is not as quiet as 80+ Platinum one
• Some people might find 750W a bit too low today (1kW model is coming, ETA early 2023 in SFX-L)
