    Default Seasonic m12ii 520 EVO good enough in 2019?

    I have this unit just lying around at my place, totally unused in the Box itself. Thinking of using it in my upcoming Ryzen + RTX 2060 build with the following specs.

    Ryzen 5 2600x(temporary, will upgrade to the newer Zen 2 CPUs as they come out)
    Noctua NH D15S
    MSI B450M Mortar Titanium
    2 Corsair Vengeance pro RGB RAM 3200Mhz
    RTX 2060 Founders edition
    Seasonic M12II 520watt Evo (fully modular)
    4 case fans + 2 HDD + 2 SSDs


    System will be used for gaming and usual desktop work, Will it do the job? I know its group regulated but will that be a major problem? And what about overclocking using this?

    No, its a low end, group regulated units with lacking protection, that got beaten by most similarly built units from other manufacturers like Corsair VS, even Cooler Master Master Watt Lite and MWE - wich do not lack protection.
    And its really really loud as well.

    You shoulr really look into other units.

    I really don't get why people consider that unit, especially for that price...
    Over here you can get entry level (230VAC only) Gold units from other companys that are far better...

    Use it for now, but definitely update the PSU before you get that Zen 2.

    Seasonic m12ii is a good unit to stay in its box, to use when you need an emergency PSU, or for troubleshooting.
    CPU: Core i7 8700k, HT enabled, all 6 cores OC'd to 4.8GHz, Vcore = 1.24v
    Heatsink: Noctua NH-D15 with one NF-A15 1500 RPM PWM fan
    Motherboard: Gigabyte Z370X Aorus Gaming 7
    RAM: 4x16GB (64GB) Corsair Vengeance LPX DDR4 RAM 16-18-18-36@3200MHz, Vdimm = 1.35v
    GPU: MSI GeForce GTX 1080 DirectX 12 with 8GB 256-Bit GDDR5X

    Thank you for the reply! Can you help suggesting me a decent unit under Rs8000(can stretch to rs9000) over here at https://mdcomputers.in/. Looking at the RM1000X, its on sale at Rs8750(now bascialy cheaper than or equally priced to the RM550/RM850). Seems overkill but fits in the budget, what about other cheaper fully modular suggestions?
    Unit has to be fully modular at least, and rest you know better than me.

    Is it because of the watts or the fact that ripples are comparatively higher than the newer units these days. How does it fare with the VS and CX series?

    He got the unit.
    I would stick with what jonny said.
    VS is group regulated too with sleeve baring fan.

    That is a very good price for that unit, although its way over what you need there is not anything that competes with a price like that.

    Neither.

    It's mainly because of the outdated design (DF + group regulated topologies) and lacking protections with its 8-pin HY510N. Due to the group regulation, it has lousy voltage regulation and no support for modern CPU sleepstates.

    Voltage regulation on the M12ii is similar to the Corsair VS grey label. Ripple on the Seasonic is better, though it's not bad on the VS.
    The M12ii gets pretty loud at high loads.
    Build quality (longevity) I'd say is better on the M12ii.
    And of course, the Corsair VS uses a better, 16-pin protection IC with a full set of protections. This alone would be the deciding factor for me.

    Corsair VS review: http://www.f14lab.com/2018/03/review...450w-2018.html

    The Corsair CX is much better than both.

    I say its not because tiny heatsinks, shitty Protection IC and other stuff...
    In the end the "Build Quality" thing is mostly coffee cup reading anyway and assuming things.

    Lets just ignore the Capacitors and look at everything else:
    you still think that the "Build Quality" of the S12II is better??

    There are some things that are really not that great on the S12II.
    For example putting a capacitor right next to a main heatsink that gets hot and also is tiny. So that the Capacitor gets heated from that heatsink.

    This stuff killed most of FSP GHN and HHN, wich had a Capacitor between the secondary coil and the heatsink!
    In the end the S12II Bronze is still a budget design, a cost down version of the S12...


    Buttom line:
    No I do not think that the "build quality" of the S12II is particularly good or better than competing products...
    But I have this:
    https://www.tech-review.de/include.p...d=16507&page=4
    And also 2 Dual PCB NMB PSU...


    PS: PFC Diode seems slightly better on the HEC....
