As an Amazon Associate we earn from qualifying purchases. Links on this page are affiliate links.
The RGEEK Mini ITX DC to DC ATX Power Supply delivers 300W of power from a 11.2 to 12.6V DC input. It features a compact 6.38-ounce design with built-in short-circuit and over-current protection. If you are searching for rgeek 1106 DC to DC alternatives, you may need a different form factor or wattage. Some users require a standard ATX extension kit instead of a dedicated DC unit. Others need a higher-wattage SFX unit for gaming graphics cards.
We selected these alternatives because their specifications overlap with the original RGEEK unit. The list includes options for silent operation, such as the fanless FOSA 350W model. It also covers high-efficiency choices like the 80 PLUS Gold Be Quiet! SFX L 600W. For those needing simple cable management, we included heavy-gauge extension kits from EZDIY-FAB and AsiaHorse. Each product addresses specific build constraints, whether you need a smaller footprint, a different input voltage, or dedicated PCIe connectors. This guide helps you find the right power solution based on your exact hardware requirements.
How these alternatives compare
EZDIY-FAB 16AWG 300mm PSU Extension Kit
The EZDIY-FAB extension kit is not a power supply. It provides 300mm cables with 16 AWG wire to extend existing connections. You must already have a working PSU to use this kit. It differs from the RGEEK by adding cable length rather than generating power. Choose this if your build needs reach. It lacks voltage conversion. It does not offer protection features. It is strictly a routing solution for cleaner cable management in tight spaces.
FSP 220W Mini ITX PSU
The FSP 220W Mini ITX PSU offers certified efficiency with Active PFC. It provides less wattage than the RGEEK 300W unit. Its dimensions are 1.6 by 3.2 by 5.9 inches. It weighs 1.8 pounds. This unit is AC input, unlike the RGEEK DC input. It fits users who prioritize efficiency over raw power. It is not suitable for high-performance graphics cards. Pick this for light-duty builds where certified efficiency matters more than higher wattage or DC input flexibility.
Apevia SFX 400W Power Supply
The Apevia SFX 400W power supply delivers higher wattage than the RGEEK. It provides up to 28A on its single 12V rail. It includes dedicated PCIe connectors for graphics cards.
