    Default Seasonic M12II-520W loud fan -> Higher PSU needed

    Hi,

    I bought this PC a few months ago:
    i5-4670K@4.3Ghz 1.16V
    Cooler Master Hyper 212 EVO
    Asus Ranger VII
    Sapphire 7850 (replaced with 290 tri-x)
    G.Skill 2x4GB 2133Mhz 1.65V
    Samsung SSD 120GB
    2 x HDD (72000rpm)
    Sound Card: Asus Xonar D2X (PCI)
    Seasonic M12II 520W

    As stated, I replaced my old 7850 with a new 290. When overclocking and under load the PSU's fan starts making a lot of noise (even more than the GPU).
    I think it's safe to assume that a higher potency PSU is needed.

    I have been reading quite a lot regarding which one I should buy.
    I live in spain and I have found the following PSUs.

    Enermax Revolution 720W for 99€
    (I know 730W is too much, but the 630W one costs only 4€ less)

    Super Flower Golden Green HX 650W for 75€

    Silverstone ST70F-ESB 700W Bronze for 72€


    Enermax Gaming Eco 650W for 74€

    Antec True Power 650W for 75€


    Antec High Current Gamer 620W for 74€

    FSP SI Gold 700W for 63€

    I can't decide which one to buy or if the Enermax Revolution (Tier 1 in Eggxpert) is really worth the extra money.



    I would really appreciate any kind of advice!

    Thank you

    You don't need more watt, just a silent PSU is enough.

    Ok, just want to be sure its clear that I will surely apply more volts to my CPU in the future (1.25 or so depending on the frequency achieved) and the GPU consumption jumps from 180W to 230W when overclocked (according to the GPU inner sensors which according to what I've read don't take into account all the consumption).

    I trust your opinion, just want to be sure!

    If what you told me stays true I would like to know two things if you don't mind:
    1- Can I make the my PSU silent? Even if that means tweaking/replacing the PSU fan.
    2- Will the high load affect the PSU/PC lifetime in any way? I want the pc to last 4 years at least.

    Thank you a lot for your fast response!

    I don't think fanswap will do much in this case, Seasonic's fan controller does ramp up RPM significantly past some load %.

    Sth like this:

    Would suit your demand well.

    Thank you a lot for your answer and suggestions!

    Is there really no choice? I've never disassembled a PSU but I'm handy with the solder and similar tools.. Can't I just disconnect the fan and add another one connected via molex or to the MB?

    I wouldn't do that. The PSU needs the cooling, with another fan it probably gets to hot.

    It shouldn't.

    You absolutely do NOT need a more powerful PSU. You need one that's more optimized to be not so loud.

    A good noise optimized 500W PSU is more than sufficient...

    You may want to look at the be quiet PSUs a little more. I don't know how good or bad the newer True Power Classics with 550W are. Some say Antec did something with the fan controller and it doesn't rev the fan up past ~300W. I can't confirm that right now...

    The problem is that I don't think I can return my PSU after 4 months just because the fan is too loud under load and I don't have the extra money right now to expend into a new one .
    I will search for more info regarding the fan replacement because if not I will probably end up with this PSU laying around so I don't lose anything trying.

    Thank you a lot for your advice, now I know that 520W is enough!

    If noise level is paramount for you, you can't expect to spend less than 100 euros, there in Spain.

    BTW among the proposed PSUs, the quietest is the Antec True Power Classic, but it's still a borderline option as its fan ramps noticeably up over 300-320W (so nearby your expected power draw while gaming).

    Noise level isn't so important for me, I always play with my headphones on. It's just too loud, as loud as my 290 tri-x at 55% (42% is the max speed it reaches while stress testing).
