Full Product Description

High-Performance 200W Power Delivery

This OEM 200W power adapter provides the stable, continuous high-current power required by MSI's most demanding gaming laptops. Standard lower-wattage chargers simply cannot supply enough energy for laptops equipped with high-end dedicated graphics cards, leading to battery drain even while plugged in. By delivering a robust 10 Amps at 20 Volts, this adapter ensures your laptop's battery charges efficiently while maintaining maximum frame rates during intensive gaming sessions or 3D rendering.

Precision 4.5x3.0mm Center-Pin Compatibility

Featuring the specific 4.5x3.0mm barrel connector with a smart center pin, this charger ensures your MSI laptop correctly identifies the power source. MSI laptops use this center pin to communicate with the adapter; if you use a generic charger without this pin, the laptop may throttle its CPU performance or refuse to charge the battery. This brand-new OEM replacement restores full functionality and performance to your machine instantly.

Pro Tip from Our Technicians

Always measure the outer diameter of your old charger's plug before purchasing, as MSI uses both 5.5mm and 4.5mm standards across different laptop models. Our Sham Shui Po repair specialists also remind you that this adapter requires a heavy-duty C5 "Mickey Mouse" power cable to connect to the wall. If you do not have a spare one, be sure to add it to your cart using the link provided above.

FAQ Section

  • Will this 200W adapter work with my MSI laptop that originally came with a 150W or 180W charger?Yes, you can safely use a 200W adapter on a laptop that requires less power (like 150W or 180W), as the laptop will only draw the amperage it needs, and the larger adapter will actually run cooler.
  • Does this power adapter come with the AC wall cable?No, this product includes the power brick only and requires a standard IEC C5 "Mickey Mouse" power cable to connect to the wall outlet. You can reuse your old cable or purchase a compatible C5 cable from our store here.
  • How do I know if my MSI laptop uses the 4.5mm or the 5.5mm connector?You can determine this by measuring the outer diameter of your old plug with a ruler; the 4.5mm version is noticeably slimmer and features a distinct metal pin in the center of the hole.
  • Can I bring my MSI laptop to your Hong Kong store to test the charger before buying?Absolutely, we highly encourage you to bring your laptop to our Sun Cheong Computer Co. Ltd. physical store in Sham Shui Po so our staff can test the fitment and charging status on the spot.
  • Is this an original MSI branded charger?This is an OEM (Original Equipment Manufacturer) adapter produced by Chicony, which is the exact same factory that manufactures the official branded chargers included in the box with new MSI laptops.
