Power Adapter Charger for Asus X751LX

Power Adapter Charger for Asus X751LX

The Asus X751LX series utilizes the traditional, robust 5.5mm x 2.5mm “big pin” barrel connector. This is a standard size for many Asus laptops from this generation. It is critical that you do not purchase a “small pin” (4.0mm x 1.35mm) adapter, as it will be physically too small to fit the charging port of your X751LX.

Asus X751LX Product Overview

This replacement AC adapter is engineered to provide the stable voltage required for the X751LX series. Depending on your specific hardware configuration—particularly if your model includes dedicated graphics—your laptop may have shipped with either a 65W or 90W charger. Using a high-quality replacement ensures that your battery charges correctly and your system does not experience performance throttling under heavy CPU or GPU loads.

Asus X751LX Key Features

• Standard 5.5mm x 2.5mm Connector Tip: The “big pin” profile required for the X751LX chassis.

• Flexible Wattage Support: Fully compatible with both 65W (19V 3.42A) and 90W (19V 4.74A) specifications. If your laptop requires 65W, a 90W charger will work perfectly as it provides more headroom.

• Smart Safety Protection: Integrated circuits safeguard your motherboard against over-voltage (OVP), over-current (OCP), and short-circuit (SCP) events.

• Durable Build: Features a sturdy cable and barrel connector designed for frequent plugging and unplugging.

Asus X751LX Pros & Cons

Pros:

• Standardized Tip: The 5.5mm x 2.5mm tip is widely available and very durable compared to newer, smaller-profile pins.

• Performance Headroom: Using a 90W charger on a 65W-rated laptop is a safe and common way to ensure cooler operation and faster charging under load.

• Compatibility: Highly compatible with a wide range of Asus power bricks found locally.

Cons:

• Connector Mismatch: Must be careful not to confuse this with the 4.0mm x 1.35mm “small pin” chargers used in newer, thinner Asus X-series models.

Asus X751LX Verdict

Your Asus X751LX requires a 19V 65W or 90W charger with the 5.5mm x 2.5mm “big pin” connector. Always check the label on your current broken charger—if it says 19V 4.74A, you should prioritize finding a 90W replacement for the best performance.
