    Beefy modular 1000w

    I picked it for the cybenetics gold rating, and ability to be efficient across different load levels, as this powers a workhorse/gaming pc, from several HDD in raid, to an RTX 5070, it seems to do the job well! Modular cables bend easily, and it even came with some combs to tidy up some of the wires you'll have to see.
