    Question Reliable PSU Recommendation - i9-9900KS

    Hello


    I need your advice for a stable, RELIABLE PSU that can operate for an estimated 3 years 24/7 powering an i9-9900KS @ 5.0GHz.


    It will be powering a server that has bursts of CPU and disk load regularly every 20-30 minutes between +-05:00 - 22:00. (It has to have eight cores and the highest reasonable stable frequency.) It will be in an airconditioned server room. From my reseach, the CPU tops out at drawing about 250-ish watts when pushed.


    I am in South Africa. I am busy getting quotes from online shops like https://www.rebeltech.co.za/63-475w-600w and also Dell South Africa directly.


    Rest of the potential system so far:
    Case: TBD/ NZXT S340 Elite / Cooler Master MasterCase H500P
    PSU: What I'm asking you. :-)
    Motherboard: TBD
    CPU: i9-9900KS
    RAM: Kingston HyperX FURY HX434C16FB3K4/64, 64GB (4x 16GB)
    Cooler: NOCTUA NH-D15
    Thermal Paste: Thermal Grizzly Kryonaut
    Drive 0: Samsung MZ-76E500BW 860 EVO SATA III 2.5 inch 500GB
    Drive 1: Samsung 970 EVO Plus NVMe M.2 1TB
    GPU: SAPPHIRE Radeon R5 230, 1GB, DDR3


    Again, the stability of the system is of utmost importance.


    Thank you

    Two topmost listings there, Corsair RMx and Cooler Master V-Gold, probably overkill for the PC with such low-load dGPU but nothing more robust there.

    No reviews on it, looking at specs sheet it's probably double-forward at least but strangely enough they don't list UVP and OTP, so no, it's not the same level. But looking there again, i see CM VSM (Vanguard) for the same price and way cheaper than those two options i've mentioned above, it would be perfect option.

That wouldn't change the fact that there are no reviews, you can't blindly say that it's good or bad without any realworld data, it would be possible to somewhat estimate how it would perform if we knew that this same platform were used in other PSUs but i can't find any info on that, FSP PSUs lineup are complete mess. And admittedly i'm not very good at PSU internals either.

    ATX 2.31 version on box. ATX 2.31 include main protection option "all in one"

    https://www.techpowerup.com/articles...s/ATX_2.31.pdf - p.28

    P.S. FSP веников не вяжет. 70$ + 5 лет гарантии + ATX 2.31! Они сами делают блоки питания, в отличие от некоторых.

    Well... To be fair, Intel lets you implement OPP in lieu of OCP, so saying it's "ATX 2.31" doesn't mean anything.

    Still would be good to know what supervisor IC is used. They typically use the P113A, which does not have OCP. That would be a dead give away that they're using OPP.

    As for OTP: Just about any PSU with a thermally controlled fan has OTP. It's pretty simple to have the circuit trip the PWM controller if the fan controller feels that a max RPM is required.

    Why can't you request an FSP? What are the barriers?

    Request what ? A review sample ? Looks like Jon doesn't review stuff anymore, for a while now.

    My concern are mainly about the lack of UVP, at least it's not listed in specs. Which puts this units very low if it indeed lacking. OCP isn't as much needed if there are OPP AFAIK (glad to be corrected). And with OTP on high-end units in range of 150C it hardly would ever shutdown unless you're mining on it in hot box, so it's kinda low priority too.

    Sorry but that's not a valid argument by any means. Regardless of brand on the label, we're evaluating the product itself, and this PSU seems to be lacking UVP which is a big red flag.
    And back to OP's question, they'll be better off with CM VSM which is very good unit with complete protections set, on LLC resonant topology, 80+ Gold (which kinda doesn't matter much but still), in comparison with most likely double-forward (hard switching, i.e possible coil whine), no UVP and OTP, 80+ Bronze unit for the same price.
    Also (not gonna start a holy war, just a mention), 'Seasonic makes their own PSUs' too, but look at group regulated S12II which they still make and sell these days and problems with old Seasonic Focus revision, the fact that they have their own R&D dept and PSU factory does no credit to them (same with all other PSU manufacturers\OEMs\brands). Look at the product, not the brand.
    PS: Sorry that i answer in English, this is international forum, if you would like to discuss in Russian you're welcome to PM me.
