Who it fits
Good fit for
This unit fits builders using Pico ATX or Mini ITX cases that require a DC input source. You should choose this if your power setup provides 11.2 to 12.6V DC directly. It is ideal for compact computers where weight matters. The short-circuit protection adds safety for sensitive components. If you need a small, dedicated power supply for a specific DC rail, this model matches your requirements.
Who should skip it
Skip this product if you need a standard AC wall plug. This unit requires a DC input, so it does not work with typical household outlets. You must have a compatible DC power source. The 300W limit may not support high-end graphics cards. If your build needs more power or standard AC input, look for a different ATX power supply. This is not for general desktop use.
Verdict: The RGEEK 1106 is a specialized 300W power supply for Mini ITX builds requiring DC input. It offers basic protection and low weight for compact systems.
Key specs for this PSU
Wattage: 300W
This rating indicates the maximum power the unit can deliver to your components. You can use it for Mini ITX builds with low-power CPUs and entry-level graphics cards. Higher-end GPUs will likely exceed this limit. Compare this against standard ATX units that often offer 500W or more for similar form factors.
Input voltage: 11.2 to 12.6V DC
The unit requires a stable DC power source within this narrow range. You must ensure your power adapter or battery system stays within these bounds. Voltage outside this window may cause shutdowns or damage. This is stricter than standard AC inputs, so your upstream power supply must be precise and reliable for safe operation.
Form Factor: Mini ITX
This physical size is designed for small cases. It fits into Mini ITX enclosures where standard ATX units do not fit. You save space for compact builds or industrial PCs. Check your case dimensions carefully. This form factor allows for portable or hidden setups that larger power supplies cannot support due to their bulk and standard mounting requirements.
Weight: 6.38 ounces
This light weight makes installation easy in tight spaces. You can mount it without reinforcing the case structure. It adds minimal mass to your overall build. This is significantly lighter than traditional metal-cased power supplies. You benefit from easier handling and less strain on small case brackets or custom mounting solutions during assembly.
Protection: Short-circuit and overload
The unit shuts down if it detects a short circuit or peak current. This protects your motherboard and components from damage. You get defensive functions for +3.3V, +5V, and +12V rails. This safety feature is essential for unattended operation. Compare this with basic units that may lack automatic shutdown, risking hardware failure during electrical faults.
Design and Build Overview
According to the listing, this unit weighs 6.38 ounces. That light mass makes it easy to mount in tight spaces. The Mini ITX form factor ensures it fits standard small cases. You do not need to worry about large footprints blocking other components.
The power supply uses a DC input connector with a 2.5mm inner diameter and a 5.5mm outer diameter. This barrel jack style is common in industrial and compact builds. It allows you to connect directly to a DC power source. You must ensure your power adapter matches these dimensions exactly.
The model number is LR1106-250W12VDC. The listing states a 300W output rating. This combination suggests a focus on efficiency in a small package. The defensive functions for +3.3V, +12V, and +5.00V outputs add a layer of safety. The unit shuts down if the output current peaks or if a short circuit occurs. These protections help keep your components safe in case of a fault. You can rely on these specs for basic stability. The simple design means fewer points of failure. This makes it suitable for embedded systems or lightweight PCs where space is at a premium.
Setup and Everyday Use Guide
Installing this unit requires a direct DC power source. You must provide an input voltage between 11.2 and 12.6V DC. This narrow range means you cannot use standard wall outlets. You need a compatible DC adapter or a battery system that stays within these limits. The connection uses a 2.5mm inner diameter and 5.5mm outer diameter connector. Ensure your power source matches these dimensions exactly. A mismatch will prevent the unit from receiving power.
Once connected, the unit manages power delivery to your Mini ITX components. It provides 300W of output. This capacity suits low-power CPUs and entry-level graphics cards. You should verify that your total component draw does not exceed this limit. The unit includes specific protection features for daily stability. It shuts down the output if the current reaches a peak point. This prevents damage from sudden surges.
Short-circuit protection is also active. If a short circuit occurs, the output shuts down immediately. This defensive function covers the +3.3V, +12V, and +5.00V rails, including the +5.00V SB standby rail. These protections help maintain system integrity during unexpected electrical faults. The lightweight design, weighing 6.38 ounces, simplifies mounting. You can secure it easily in tight spaces without adding significant weight to your chassis. This setup is ideal for users who already have a suitable DC power supply ready to connect.
Before You Buy This Mini ITX PSU
You need a compatible DC power source to run this unit. Standard wall outlets will not work. You must provide 11.2 to 12.6V DC through a 2.5mm inner and 5.5mm outer diameter connector. Check your cable and adapter dimensions carefully before purchasing. This narrow input range limits your power options. You should verify that your components stay within the 300W limit. High-end GPUs or CPUs may exceed this rating. The unit includes short-circuit and over-current protection. These features help safeguard your build during unexpected current spikes. You should monitor your system temperatures regularly. Compact units can run warm in tight spaces. This PSU fits best in small form factor builds. It suits users who already have the correct DC power infrastructure. It is not ideal for beginners who need plug-and-play simplicity. Compare this against other Mini ITX options if you need broader input voltage ranges or higher wattage. Always ensure your case supports the Mini ITX form factor. Proper ventilation is essential for long-term reliability.
Check before you buy
- Verify your DC adapter matches the 2.5mm inner and 5.5mm outer diameter.
- Ensure your power source stays between 11.2 and 12.6V DC.
- Check that your total system draw stays under 300W.
- Confirm your case supports the Mini ITX form factor.
