    This review is about the power: 750 W

    It burned out after 3 months, it suddenly made a spark and that was it. It was measured with a multimeter and has a leakage, it is now dangerous, maybe it was defective

    Very high-quality power supply. It has all the cables it should have. It is also quite silent and a brand of power supplies that you can trust with your eyes closed.

    Trash. I chose this one for its supposed reliability and energy efficiency. It arrived in a brand new built-to-order system and managed to break down in just 10 months, with very light use.

    Because the store I bought it from had closed in the meantime, I contacted the company, which does NOT have a representative in Greece. They told me to send it to their headquarters in Germany, at my own shipping cost, which would have been 2/3 the price of a new one.

    Obviously, there was uncertainty as to whether the company would send a new or repaired replacement for the defective item, or if they would try to completely disclaim responsibility.

    In the end, I bought a BeQuiet and truly found my peace.

    I do not recommend Seasonic products at all.

    I haven't noticed any problems. It is silent and functional, and for full wired, it has easy cable management and installation. I got it at 650w and have it connected with RX 7600 and i5 13400f. The purchase was made at €75. Reliable brand as far as I have been informed and a very good model.

    This review is about a variation of the product

    Seasonic is one of the best power supply manufacturers out there and often makes power supplies for other companies which then simply put their own brand on them.
    The specific one I got (G12-GC-650) is quite silent and has its cables relatively well organized.
    With this, I replaced my old power supply which, due to its age and usage (at least 15 hours a day), had started to reach the end of its life, mainly because its capacitors had "aged".

    This review is about the power: 750 W

    Purchased for €120 in the summer of 2020.
    It spent all of 2021 mining with 2 graphics cards 24/7.
    Now, it plays games but not intensively, as time...
    So far, I have had no problems.
    Of course, I am not an electrician, but this company has the best reviews.

    26/02/24: It still works perfectly.
    07/10/24: For the past 5 months, it has been mining with two 3080ti. It continues to work flawlessly.

    This review is about the power: 550 W

    I mainly bought it for a Plex server (low-mid range system). It has plenty of SATA and molex connectors so you can connect multiple hard drives. The power supply is quiet (at least for me). In terms of wattage, it's okay, I didn't need a lot of watts anyway. It's gold certified and it's from Seasonic, which we all know is one of the top manufacturers. It's Tier B according to forums. So it's one of the best purchases I've made.
