and even that thing isn't a Seasonic design... it's RSY

just as a confirmation from our side Dark power pro 12 - CWT Dark power 12 - FSP

without heavy modifiction they would also make for awful PSU fans

review of RMx 2021 is out since today https://www.techpowerup.com/review/corsair-rmx-series-850-w-2021/ tldr: - similar base to RMx 2018 - different controller (to meet low load efficiency) - different fan (custom HongHua -> Custom Sunon) - new housing design - really weird cable choices - low load effciency is better, average is worse should be added with next revision

just now

sadly, EVGA doesn't send out reviewer samples so all we can currently do is take an educated guess from the backside. It looks to be a platform similar to CV650, basically a smaller versoin of BV. Do keep in mind that many cheap "FDB" fans are often either sleeve or rifle bearing

well... the undervoltage protection seems to be completely non-functional, considering it dropped to a staggering 6 volts on the 12v rail, with the Chroma connected to it indicating around 100a, and they stopped the test below is a google translate version of the German review this came from (@hardwareluxx)

CXM uses a platform completely different from CX

this is the Gray label, only RM has a "black" label for the current model

expect tier a unless I find something off about it

it is, hardwarebusters = aris

there is info about them since. It's a CWT GPU, making it tier A multirail, since it's very similar to Bitfenix Whisper, Deepcool DQ-M (V1) and Enermax Revolution DF

hm... I've seen them show off a prototype before in I think 2019@computex took them a decent while

oh, of course some of these can be caused by different issues it's just that I took some out that were longer than "DOA" or alike. It's to give a view of the general picture

TL;DR Gigabyte is refusing to support a product they know to be problematic. This is as of the time of writing still in production with the same components. We haven't asked Gigabyte for a public statement. Most likely problem - Main FETs To start, a quote from Aristeidis Mpitziopoulos', which in this article will be referred to as Aris, review on Techpowerup about this very unit below. This is something alarming on it's own already. The main FETs on the power supply explode after having handled a heavy load. They didn't fail during the actual OPP/OCP testing itself, but a few minutes after when the unit was turned on again. But this is sadly only the component that seems to cause most of this issues... Gigabyte handling this finding - we tested it and it's fine From here, Aris attempted to send his findings to Gigabyte. They chose to not recall the unit they sent him and tested around 10 units internally in their RMA division. From here, no issues were found and this was reported back to Aris. This is in every way a flawed way of testing. More about this can be found in the video here: Gigabyte handling it's consumers - refusing support Gigabyte has had many reviews on sites like NewEgg that claim DOA units, extreme coilwhine, killed components and much more. Normally I'm not one to react off consumer reviews because of their flawed nature, but when almost a majority of users has failures and there's a ground of suspicion what is the problem it becomes a different story. A few quotes below These are a few of the more elaborate reviews. As of the time of writing, 142 out of the 242 reviews on the PSU are 1 star or "egg", all coming down to either extreme coil whine, system instability or the unit dying with no way of returning it without including the 3000 series card they bought it with. Even if it's understandable that Newegg/Gigabyte doesn't want a scalper to buy this and attempt to return the PSU, with a genuine failure this is an outright stupid thing to do.

There are no exact numbers out there on the actual failure rate of the unit, but this isn't down to an early production sample unit or the occasional "lemon" you get with mass production. This is a widespread issue that can only be solved by using different parts in the PSU. They can either choose to take it off the market, issue a full recall and give people their money back, or introduce a revision/newer version of the product with higher end FETs from for example Infineon, with likely also a lower OCP/OPP setting.

main FETs*

highpower #817, expected is tier b when we add it

from a very quick look it looks like a Greatwall EPS1250DA variation... which would likely place it in tier c

This thread is for questions around the list and possible additions to it, we have a whole forum for recommendations around specific cases

looks like a Greatwall to me... very similar to CX

Cooler master themselves and well... Aris' public testing if you want something more public
