FAQ
A small computer power supply is an internal PSU designed to fit a compact desktop case. SFX and SFX-L are common choices for custom small form factor builds. Small refers to physical size, not necessarily output: compact models can still deliver the wattage needed for demanding components.
SFX power supplies typically measure 125 mm wide, 63.5 mm high, and 100 mm deep. SFX-L models share the same width and height but are typically 130 mm deep, allowing room for a larger fan. Check the exact product dimensions and your case's clearance, including space for connectors and cable routing.
No. Mini-ITX describes the motherboard size, not the power supply mount. Depending on the design, a Mini-ITX case may support SFX, SFX-L, ATX, or another power supply format. Check your case manual for supported formats and maximum PSU depth before buying.
Base your choice on the components, not the case size. Check your graphics card manufacturer's PSU guidance and account for the processor, drives, fans, and other hardware. Choose a unit with enough capacity for the complete system and some room for upgrades, while confirming that it includes the required connectors.
Yes. A fully modular power supply lets you connect only the cables your components need, reducing unused wiring in a tight case. Check cable lengths and connector clearance as well. Use the supplied cables or replacements explicitly approved for that exact PSU model; modular cables are not universally interchangeable.
No. ATX 3.1 can describe the power supply's electrical specification rather than its physical size. An SFX power supply can meet ATX 3.1 requirements while retaining a compact body. Check the listed form factor for case fit and the connector specifications for graphics card compatibility.
Not automatically. Some prebuilt desktops use model-specific power supplies, mounting points, and motherboard connectors. Match the computer's exact model and original PSU part number with the replacement's compatibility information rather than choosing by wattage or size alone.
