    Default Help me chose a good PSU?

    Hello everybody,

    I'm a new user, abeit I have been a silent ghost herearound for a while :P

    I am looking for advice selecting a new PSU for my rig.
    You can see its specs in my signature, but here they follow as well:
    Code:
    CPU Intel Core i7-66700k
    Motherboard ASUS Prime Z230-A
    RAM 16GB DDR-4 Corsair
    GPU Nvidia GeForce GTX 1050
    PSU CX750M
    1 x SSD 120GB
    2 x HDD 7.2RPM
    1 x 80RPM fan
    1 x CoolerMaster Seidon 120 liquid CPU cooler
    LG BD-Writer
    FrontBay 2 x 2.0 USB ports + 3 x USB 3.0 ports + cardreader
    K260 combo wifi KB+mouse
    external USB wifi adapter
    ..and my trusty USB 2.0 TARDIS Hub
    As you can see, I am actually using a Corsair CX750M PSU...which proved to be a real s***.
    I bought it two years ago, and it literally fried two MSI "mortar" motherboards.
    I suspected power surges to be involved, so I basically replaced the PSU with a new unit (same model), I changed my motherboard and GPU as well, and all went well for a few months...

    ...then my PC started to reboot randomly as soon as it reaches OS login (win10x64 here)....and I read around about the CX750 to be a pile of crap.

    That was the last straw, and I think I am done with Corsair, at least for the moment being.

    I made my calculations, and I probably need no more than 400W to power up my rig...I would go for a 600-650W to be on the safe side...I live in EU and I would like to spend fair money for my PSU, since I'm not the richest guy around :P
    That said, I'd love to spend less than 100 euros, if possible, but I am prepared to spend more, if needed: I already took the "cheap" step, and it cost me a lot...

    Care to suggest me some decent option(s)?

    Many thanks in advance for your help and contributions.

    Pino

    Ever heard of a surge protector?

    CX M is definitely not a decent high end psu, but it is also far from crap. Guess that your one is just faulty or it is not because of PSU.

    First of all, I thank you both for your answers.
    For the sake of argument I will tell you:
    1. that a surge protector is already in place. I put it over a year ago; and it works;
    2. that the CX M broke already once. And is probably already broken again, I throughly tested all other components in my rig.

    That said, I'd like to get back to my original topic: could you please suggest me an alternative PSU to replace the current one?

    So you're done with Corsair because you refuse to buy a better PSU in the first place and buy their cheapest model?

    Fascinating.

    I should have gotten into psychology instead of engineering because the way the human mind works is far more fascinating.

    What was it about the CX750M that "fried" two motherboards? That PSU is cheap, but it still functions within ATX specs, no? And if not, then it is within the warranty period, yes?

    Uhm...isn't that a bit rude?
    I came here on these forums for a quick suggestion, since I think this is one of the best places on the topic of PSUs (if not the best place).
    All I did was ask a question, politely and providing all the relevant details, as per forums instructions...how and why I am reasoning is frankly not relevant, and I would be grateful if you would keep futile and quite offensive comments like this for yourself, thank you.

    I wrote that my current PSU has been replaced with a new one ot the same model. I asked Amazon for a replacement, and they did.
    My warranty period probably still covers the new unit as well...but since it failed me once and it is probably failing me twice, I would like to steer clear of it.
    When the first accidents occurred, I assumed that the previous MSI mortar motherboards were faulty, since they both fried in different places (I am not a technician, but again I did not think this to be relevant for the topic)...now, since my PC started once again to act funny with a different board, it downed to me that the issue might have been the PSU unit from the start. My current issues occurr with different GPUs, different RAMS and different HDDs...so this has to be the PSU...I did a good search online and I found out thatmany people complaining about my specific model. That is why I decided to spend my money on another horse.
    Would you please suggest an affordable and reliable one?
    Many thanks again.
