    My last Seasonic PSU lasted 14 years before dying (and this one was the cheapest 80+ gold modular PSU from a reliable brand) so I decided to go with them again. I'm glad I did, because this PSU is great! The fan is super quiet (I don't hear it over the other fans), the voltages are very tight (0.25-1.5% off at the most), and semi modular is nice to have (I only needed one SATA power connector besides the non-removable cables).

    It also includes 8 zip ties, 3 velcro straps, screws, and 2 bags (even thought the picture only shows 1) as accessories. The large zip tie holding the cables in the box is reusable, so make sure not to cut it.

    Great PSU. Runs quiet and included a bunch of useful accessories. This was my first Seasonic purchase (usually buy Corsair PSUs), and would buy them again. They have amazing Amazon review statistics.

    Semi-modular is nice and it removes a lot of the clutter from unused cables. Only the ATX and CPU cables are fixed, which is fine because these are required by the motherboard.

    Excellent quality PSU with solid performance. It has semi-modular cables helps to keep the build clean. Bought it for $69.90 from Amazon.

    Well reviewed esp by JohnnyGuru. I guess I will know in 10 years time if it is as good as they say.

    Got semi modular since it is cheaper. Would go semi again as I wouldn't be replacing the cables. Easy enough to work with and the ports on the PSu are well labelled. Enough cables supplied and long enough for me.
