The Lian Li O11D Mini is a brilliant PC case, but you will need a compact SFX power supply to power everything. I've rounded up some of the best PSUs out there that would work well with many PC builds, depending on how much budget you have to spare.
Best Overall
Looking for a compact PSU to fit the Lian Li O11D Mini? Look no further than the Corsair SF Series SF450, which comes with a rating of 80 Plus Gold, meaning it's pretty efficient for even more powerful PC builds. We've selected the 450W model which should be able to provide enough power to a single CPU and GPU PC. It's modular and has a no-fan operation mode at lower loads and comes with a massive seven-year warranty.
Best Budget
The EVGA SuperNOVA is a great value PSU range for compact PC builds. This 650W model is ideal for most builds with a single GPU and CPU, allowing you to install an AMD Ryzen 9 and NVIDIA GeForce RTX 30-series GPU inside the Lian Li O11D Mini with ease. It's 80 Plus Gold rated, meaning it should be efficient enough at half to full load, as well as fully modular, which keeps a clean build.

Choosing the right power supply largely comes down to the efficiency rating, power capacity, and price. So long as you pick an SFX PSU from a reputable brand, such as the recommendations we have in this collection, you'll be able to pick up a power supply that'll perfectly match your PC build inside the Lian Li O11D Mini.
We chose the Corsair SF Series as our top pick, with the 450W model the best option for value and performance. You've got a solid 80 Plus Gold rating and it's fully modular, which is perfect with the Lian Li O11D Mini for cable management. It may be a little underpowered for more powerful NVIDIA GeForce RTX 30-series GPUs, however.
