Description

The G12 GC series is available in the standard ATX Form Factor and in wattages that are most common for a computer system.

The Seasonic G12 GC-Series achieves the 80 PLUS Gold standard by providing at least 87%, 90%, and 87% energy consumption efficiency at 20%, 50%, and 100% operational loads, respectively. This efficiency, combined with active power factor correction, allows the G12 GC series power supplies to reduce energy waste, which translates into cost savings on energy costs for its users.

Beyond being efficient, the G12 GC units utilize the LLC resonant converter design and the industry's leading Smart and Silent Fan Control (S2FC).

The G12 GC achieves 80 PLUS Gold certification with 90% efficiency at 50% system load.

Smart / Silent Fan Control

    This review is about the power: 650 W

    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.

    It is one of the best PSUs available at this price, it really deserves its money even though it is not full modular or semi, it has very long cables and you can easily do cable management

    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.
