    Corsair RMe 1000 in ATX 3.0 version looks good, nothing on the smaller units yet.

    Only review so far, but looks like a quality one (can't read it as it's in Chinese, but the graphs are pretty universal):

    I'm happy with my 750W ATX 3.0 Corsair RM750e I picked up at Best Buy for $90. Very quiet running my i7-13700K/RTX 4070 Ti Super rig.

    Picked up a factory refurb (so likely just a return) of the same and am quite happy with it. Though slightly annoyed that the RTX3k-series 12-pin isn't actually ATX 3.0. (it's 12-pin, not 12+4-pin)

    Extreme PSUs Incoming: Enermax, Leadex, and Seasonic at Up to 2800W

    www.anandtech.com www.anandtech.com

    Not a review but didn't necessarily seem worth its own thread.

    Upcoming ATX 3.1 power supplies with pretty high max power:
    • Seasonic Prime PX 2200W (only a single 12v-2x6 connector seems odd), no release date mentioned.
    • Enermax Platimax 2400W (two 12v-2x6 connectors at least...), $499 when released December 2024.
    • Superflow Leadex 2800W Platinum (two 12v-2x6 connectors at least!), $599 when released later in 2024.
    Given the Seasonic Prime PX 2200W unit was demo'ed at Computex with 4x RTX 4090 and a Threadripper Pro 7995WX with 256GB....

    Dont know if it already been talked about but Corsair has (finally) refreshed it's lauded SFxxx (not L) line and added some higher power models (750/850/1000), also interesting is the fact that they dropped 80Plus accreditation (supposedly due to cost and being outdated) and one of the bigger change is the dropping of the -12v line.....

    Woah, whaaaaaa... will have to look more when I have time. Still Cybernetics certified, again will have to look at reasons why...

    Coolermaster V850 ATX 3.0 SFX 80PLUS Gold review. Looks great at normal temps, but like any high power SFX PSU (say above 650W or so), not good at max load at high temps (aka in Anandtech's hotbox).

    From the Hardware Busters Corsair SF750 linked by @reckless_sniper above:


    With the new SF series, Corsair marks its independence from the so-far powerful 80 PLUS, which insists on increasing its fees while using a vastly outdated and easy-to-cheat methodology. According to Corsair’s PSU PM, only the Cybenetics ratings will be utilized from now on. These ratings use the average efficiency and noise readings from at least 1450 different load combinations, from minimal to full load, and other data to tax the PSUs to the corresponding efficiency and noise categories.

    I don't specifically mind them dropping certification for a product line, as long as the product gets cheaper accordingly and the usual suspects get to review the parts in depth near/before launch.
    If they drop the certification and embargo the launch or provide no review parts then it gets an instant "I'll hold off on that for now."

    TBH, The 80Plus dropping sounds definitely like a JonnyGuru decision lol. The guy can be a prick at times (see his dustup with GN, also his forums/website back then) but he's really been in the forefront for really good PSU designs/decisions.

    But looking it up, It seems like 80Plus been abused by some manufacturers, one is by designing PSUs with crazy efficiencies but have issues delivering them either consistently or instantaneously (either very conservative OV/OC protection and/or inherent design issues), and another issue is that it doesnt have any noise ratings (both something that Cybernetics tests for).

    Jonnyguru pretty much disappeared to run 80PLUS, anyone have anymore insight on what's going on with 80PLUS?

    Sounds like some oversights in 80PLUS methodology which Cybernetics does differently, again quoted from Hardware Busters SF750 review linked by @reckless_sniper:
    You should expect slightly lower efficiency and increased voltage drops with longer cables because of the increased resistance, especially at high loads. This is why many manufacturers send units for efficiency certification at 80 PLUS, with super-short cables. This cannot be the case in Cybenetics, where the above cable description table is included in all reports.
