Cases with a power supply are computer cases that come with a PSU already fitted, so you do not need to buy one separately. They suit office, home and basic workstation builds. Our range includes small SFF and mini tower models from manufacturers such as CHIEFTEC, LC-Power, Cooler Master and Supermicro.
How to choose a case with a power supply
Case size and motherboard format. Decide first how large the PC should be. Our range includes SFF and mini tower cases made for Mini-ITX and micro ATX motherboards. A full-size ATX board will not fit in these, so check the supported form factors before buying.
Power supply wattage. Our range includes cases with 300 W and 350 W power supplies. That is enough for an office PC using integrated graphics, but not for a power-hungry graphics card. If you plan to add a separate graphics card, check the power supply wattage its manufacturer recommends.
Graphics card and CPU cooler clearance. Maximum graphics card length in our cases runs from about 14 to 34 cm, and CPU cooler height from 5 to 14.5 cm. Small cases often take only a low-profile cooler, so compare these dimensions with your own components.
Storage and cooling. Many models have a single 3.5-inch bay for a hard drive, and one has three. SSDs need far less room. Front fans are mostly 80 mm, and some models take 120 mm. At the same airflow, larger fans generally run more quietly.

Frequently asked questions
Is a 300 W power supply enough for a PC?
For an office or home PC with integrated graphics, 300 W is usually enough. If you add a separate graphics card or a powerful processor, first check the power supply wattage they recommend. If 300 W falls short, the supply will need replacing.
Will a separate graphics card fit in a small case?
It will if the card is shorter than the maximum length the case allows. In our range this limit runs from about 14 to 34 cm. Small SFF cases usually take only short or low-profile cards.
What is the difference between an SFF and a mini tower case?
An SFF case is smaller and often built for Mini-ITX or micro ATX boards, so it leaves less room for upgrades. A mini tower is usually larger, which allows a longer graphics card, a taller cooler and more drives. Choose according to how many components you plan to fit.
Can I replace the power supply in the case later?
Usually yes, if the unit is a standard size and uses ordinary connectors. Some small cases use a non-standard power supply, which makes replacement harder. Ask which power supply format is fitted before you buy.
