Always verify compatibility with your specific Mini PC model before purchasing a replacement power adapter. A Mini PC is only as reliable as the power that flows into it. The humble power adapter – often called a power brick or AC adapter – is easy to overlook until it’s lost, damaged, or fails. Then, suddenly, your compact computer becomes an expensive paperweight. Finding the right replacement can be confusing: different Mini PCs use different voltages, amperages, connector sizes, and even power delivery standards. According to a report by the Consumer Technology Association, power adapter failures account for a significant percentage of support calls for compact computing devices. PCMag notes that “using the wrong power adapter can not only prevent your device from working but can actually damage it permanently.” Whether you’ve lost your original charger, need a spare for travel, or your current adapter has stopped working, this guide will help you navigate the world of Mini PC power adapters. You’ll learn about the different types, how to find the right specs, where to buy replacements, and what prices to expect.

By the end of this guide, you will have a complete understanding of Mini PC power adapters and how to choose the right one. browse nowistech’s curated selection of power adapters and accessories → Key Takeaways: Voltage and Amperage Matter — Using the wrong voltage can destroy your Mini PC. Always match exactly. Connector Size is Critical — The barrel plug size varies; 5.5mm x 2.5mm and 5.5mm x 2.1mm are common, but not universal. Wattage Requirements — Ensure the adapter can supply enough power (watts = volts × amps). Going higher in amperage is safe; lower is not. USB-C Power Delivery — Newer Mini PCs may charge via USB-C PD, offering more flexibility and universal compatibility. Genuine vs. Third-Party — Genuine adapters are safer but more expensive; quality third-party options exist but require careful selection. Universal Adapters — Adjustable voltage adapters can work, but risk if set incorrectly. Not recommended for beginners. What Power Adapter Do You Need for Your Mini PC? To help you identify the correct power adapter, we have compiled specifications for popular Mini PC models. This comprehensive table breaks down each model’s power requirements. Mini PC Model Voltage Amperage Wattage Connector Type Connector Size Typical Price (Replacement) Beelink Mini S12 Pro 12V 3A 36W Barrel 5.5mm x 2.5mm $15-$25 GMKtec NucBox G3 12V 3A 36W Barrel 5.5mm x 2.5mm $15-$25 Beelink SER5 19V 3.42A 65W Barrel 5.5mm x 2.5mm $20-$30 Geekom Mini IT11 19V 3.42A 65W Barrel 5.5mm x 2.5mm $20-$30 Geekom A7 19V 4.74A 90W Barrel 5.5mm x 2.5mm $25-$35 Intel NUC 13 Pro 19V 4.74A 90W Barrel 5.5mm x 2.5mm $30-$40 Minisforum HX80G 19V 7.9A 150W Barrel 5.5mm x 2.5mm $40-$50 Minisforum HX100G 19V 7.9A 150W Barrel 5.5mm x 2.5mm $40-$50 Dell OptiPlex Micro 19.5V 3.34A 65W Barrel (Dell proprietary) 7.4mm x 5.1mm $30-$45 HP EliteDesk Mini 19.5V 3.33A 65W Barrel (HP proprietary) 7.4mm x 5.0mm $30-$45 Apple Mac Mini M2 20V 3A 60W USB-C PD USB-C $30-$50 Important Notes: Voltage MUST match exactly. Using a higher voltage can destroy components. Using lower voltage may cause instability or failure to boot. Amperage can be higher than specified. A 12V 5A adapter is safe for a device that requires 12V 3A; it will only draw what it needs. Wattage is simply voltage × amperage. Ensure the adapter can supply at least the required wattage. Connector polarity is almost always center positive for Mini PCs, but double-check. After reviewing this table, you should have a clearer idea of your Mini PC’s power requirements. If your model isn’t listed, check the original power adapter or the device manual for specifications. dive into the detailed buying guide below → How to Identify the Right Power Adapter If you don’t know your Mini PC’s exact specifications, follow these steps to find the right replacement. Step 1: Check the Original Adapter ([Time estimate: 2 minutes]) Look at the label on your original power brick. It will list: Input voltage (usually 100-240V, universal) Output voltage (e.g., 12V, 19V, 19.5V) Output amperage (e.g., 3A, 3.42A, 4.74A) Wattage (sometimes listed) Connector polarity (diagram showing center positive/negative) Step 2: Measure the Connector ([Time estimate: 3 minutes]) Use a caliper or ruler to measure: Outer diameter of the barrel plug Inner diameter (the pin) Common sizes: 5.5mm x 2.5mm, 5.5mm x 2.1mm, 7.4mm x 5.0mm (HP), 7.4mm x 5.1mm (Dell) Step 3: Check the Mini PC Itself ([Time estimate: 2 minutes]) Some Mini PCs have the voltage printed near the power port. Check the user manual or manufacturer’s website for specifications. Step 4: Search by Model Number ([Time estimate: 3 minutes]) Search for “[your Mini PC model] power adapter” on Amazon or Google. Look for listings that specify compatibility with your exact model. Read reviews to confirm others have used it successfully. Step 5: When in Doubt, Contact the Manufacturer ([Time estimate: 5 minutes]) Email support with your model number. They can provide exact specifications or sell you a genuine replacement. Pro Tip: Take a photo of your original adapter’s label before you lose it. Store it in your phone for easy reference.

Avoid no-name generic adapters, especially for higher-wattage Mini PCs. USB-C Power Delivery: The Future of Mini PC Power Many newer Mini PCs, including the Apple Mac Mini M2 and some Intel NUC models, support charging via USB-C Power Delivery (PD). This offers several advantages: Universal Compatibility: One charger can power your Mini PC, laptop, tablet, and phone. Convenience: Fewer cables, easier travel. Future-Proof: USB-C PD is becoming standard. Flexibility: Can often use portable power banks for short-term use. If your Mini PC supports USB-C PD, look for a charger with sufficient wattage (e.g., 60W, 90W, 100W). GaN (Gallium Nitride) chargers are smaller, cooler, and more efficient than traditional silicon-based chargers.
