No problems, hasn't exploded. Semi modular seems to be a good medium between fully modular and not. I would buy again.

Using the 450W variant. Does its job fine and looks solid.

This was the cheapest power supply (I paid £44.89) that met my criteria of 140mm deep, modular (semi modular at least) and reasonably quiet. It looks good and works well. The main cables are a bit bulky and stiff, but all the connectors fitted easily

Great power supply, fairly quiet as well. Does the job well.
