Good quality, as it is Seasonic. But for a 300 watt unit that doesn't come with a box or an outlet cable, it is awfully expensive. I kind of wish that I had bought the SSR-350ST instead, but whatever.

Not unlike the Yaris' slogan of "It's a car!" it's a psu. Ain't much of one but don't need much of one. Made cable management an interesting challenge and didn't come with its own power cable for the wall outlet but in a build like this that just adds a little character. It's shown up for work and done its job everyday without a hitch. Four stars.

It works and it is low wattage. Fits for going where I need to be exactly. Just know that the model I picked does NOT have a power cable. You’ll have to source a power cable to connect to it. Very niche use but for low-wattage systems, it really is fine.
