The logical choice here is to go modular. The ability to simply remove unused power cables would work wonders for a cramped build like this, both in ease of assembly and in terms of aesthetics. There are plenty of good options, but our recommendation would likely be the Corsair RM550x, which provides fully modular power delivery for aaround $145. Of course, if you’re planning on throwing a GPU (or any other major components) into this build, you’re going to need more power. 600W is perfectly sufficient for most systems that include a GPU, with 700W providing total peace of mind. Most importantly, make sure that the power supply you choose is small enough to comfortably fit the mounting bracket in the Q500L.
