Their original 240&nbsp;W adapters are designed to feed powerful CPUs<br \/>\n    and GPUs without throttling. If your original power brick is lost, damaged or no longer reliable, you<br \/>\n    need a compatible 20V 12A 240W Asus AC adapter with the correct 6.0&nbsp;mm x 3.7&nbsp;mm connector.\n  <\/p>\n<p>\n    This article walks through the complete buying journey for the following product:\n  <\/p>\n<p class=\"product-hero\">\n    <a href=\"https:\/\/www.buy-a-charger.co.uk\/pcbattery\/product\/20v-12a-240w-asus-6-0mm-3-7mm-ac-adapter-charger\/\"\n       target=\"_blank\"\n       rel=\"noopener\"><br \/>\n      <img decoding=\"async\" src=\"https:\/\/www.buy-a-charger.co.uk\/pcbattery\/wp-content\/uploads\/2025\/08\/Asus20V12A6037.jpg\"\n           alt=\"20V 12A 240W Asus 6.0mm x 3.7mm AC adapter charger\" \/><br \/>\n    <\/a>\n  <\/p>\n<p style=\"text-align:center;\">\n    <a class=\"cta-btn\"\n       href=\"https:\/\/www.buy-a-charger.co.uk\/pcbattery\/product\/20v-12a-240w-asus-6-0mm-3-7mm-ac-adapter-charger\/\"\n       target=\"_blank\"\n       rel=\"noopener\"><br \/>\n      View 20V 12A 240W Asus 6.0mm x 3.7mm AC Adapter<br \/>\n    <\/a>\n  <\/p>\n<h2 id=\"step1\">1. When do you need a new 240W Asus charger?<\/h2>\n<p>\n    Most customers start searching for a replacement adapter only after something goes wrong. Common situations<br \/>\n    include:\n  <\/p>\n<ul>\n<li>The original Asus adapter is lost or left behind at work, school or a hotel.<\/li>\n<li>The cable is frayed, bent near the plug, or has exposed metal.<\/li>\n<li>The power brick gets unusually hot, makes noise, or has a burnt smell.<\/li>\n<li>The laptop shows \u201cplugged in, not charging\u201d or shuts down when gaming on AC power.<\/li>\n<li>A lower-wattage universal adapter was used and the laptop throttles or is unstable.<\/li>\n<\/ul>\n<p>\n    At this stage, the key question is: do you only need a new charger, or is the battery also failing?<br \/>\n    A quick test is to:\n  <\/p>\n<ol>\n<li>Check if the laptop charges correctly when completely shut down.<\/li>\n<li>Test with another known-good Asus 240&nbsp;W adapter, if available.<\/li>\n<li>Check the original adapter for visible damage or a broken connector.<\/li>\n<\/ol>\n<p>\n    If the symptoms clearly follow the adapter, a quality replacement 20V 12A 240W charger is the right next step.\n  <\/p>\n<h2 id=\"step2\">2. Confirming the technical requirements of your Asus laptop<\/h2>\n<p>\n    Before buying, you should confirm three technical details to avoid under-powered or incompatible chargers:\n  <\/p>\n<h3>2.1 Output voltage and current<\/h3>\n<p>\n    Look at the label on your original Asus adapter or in the laptop\u2019s documentation. For the product in this guide,<br \/>\n    you should see something like:\n  <\/p>\n<ul>\n<li><strong>Output:<\/strong> 20&nbsp;V<\/li>\n<li><strong>Current:<\/strong> 12&nbsp;A<\/li>\n<li><strong>Power:<\/strong> 240&nbsp;W<\/li>\n<\/ul>\n<p>\n    Your replacement adapter should match these values. A lower-wattage charger (for example 180&nbsp;W) may work<br \/>\n    at idle, but can cause throttling, instability or sudden shutdowns under heavy load.\n  <\/p>\n<h3>2.2 Connector size \u2013 6.0&nbsp;mm x 3.7&nbsp;mm<\/h3>\n<p>\n    Asus gaming and ProArt laptops use several different barrel connectors. This 240&nbsp;W adapter uses the<br \/>\n    <strong>6.0&nbsp;mm (outer) x 3.7&nbsp;mm (inner)<\/strong> round plug. Visually it looks similar to other<br \/>\n    sizes, so the safest approach is to:\n  <\/p>\n<ul>\n<li>Compare the plug in the product photo with your original adapter.<\/li>\n<li>Check that your laptop is listed in the compatible model list.<\/li>\n<\/ul>\n<h3>2.3 Worldwide input voltage<\/h3>\n<p>\n    The adapter is specified with:\n  <\/p>\n<ul>\n<li><strong>Input:<\/strong> 100&nbsp;\u2013&nbsp;240&nbsp;V, 50&nbsp;\u2013&nbsp;60&nbsp;Hz<\/li>\n<\/ul>\n<p>\n    This means it can be used in most countries worldwide. The package includes:\n  <\/p>\n<ul>\n<li><strong>1 x Asus Charger<\/strong><\/li>\n<li><strong>1 x Power Cord (fit your country)<\/strong><\/li>\n<\/ul>\n<p>\n    For travellers and international students, this ensures the adapter works with local mains voltage when the<br \/>\n    appropriate cable is provided.\n  <\/p>\n<h2 id=\"step3\">3. Checking compatibility by part number and model<\/h2>\n<p>\n    Once voltage, current and connector size match, the next step is confirming compatibility by part number and<br \/>\n    laptop model. This is especially important for powerful Asus devices that can ship with 200&nbsp;W or 240&nbsp;W<br \/>\n    options depending on configuration.\n  <\/p>\n<h3>3.1 Compatible part numbers (examples)<\/h3>\n<p>\n    This 20V 12A 240W Asus 6.0mm x 3.7mm adapter is designed as a replacement for several original Asus references,<br \/>\n    including (partial list):\n  <\/p>\n<p class=\"small-text\">\n    Asus 0A001-00392200, 0A001-00392300, 0A001-00392500, 0A001-00392600, 0A001-00393200, 0A001-00393300,<br \/>\n    0A001-00393400, 0A001-00970000, 0A001-00970100, 0A001-00970200, 0A001-00970300, 0A001-00970400,<br \/>\n    0A001-00970700, 0A001-00970800, 0A001-00970900, 0A001-00971000, 90XB05IN-MPW090, 90XB06MN-MPW,<br \/>\n    90XB06MN-MPW000, A20-240P1A, AD240-00E, ADP-240EB B, ADP-240EB BD\u2026\n  <\/p>\n<p>\n    If you can still read the label on your original Asus adapter, compare the part number with this list.<br \/>\n    A match is a strong indication that the replacement will be compatible.\n  <\/p>\n<h3>3.2 Compatible Asus model families<\/h3>\n<p>\n    The same 240&nbsp;W power profile is used across a wide range of Asus models, including high-end gaming and<br \/>\n    content-creation laptops such as:\n  <\/p>\n<ul class=\"small-text\">\n<li>Asus TUF Gaming A15 \/ A17 \/ F15 \/ F17 \/ F16 series (for example FA507, FA707, FX507, FX707, FX607\u2026)<\/li>\n<li>Asus ROG Strix G and ROG Strix Scar 15 \/ 17 series (G513, G713, G733 and related codes)<\/li>\n<li>Asus ROG Zephyrus G14 \/ G15 \/ G16 and ROG Zephyrus Duo models<\/li>\n<li>Asus ROG Flow X16 and other ROG Flow systems that ship with 240&nbsp;W adapters<\/li>\n<li>Asus ProArt StudioBook and VivoBook Pro series with dedicated GPUs<\/li>\n<li>Asus ExpertBook B6 and certain high-power workstation-class models<\/li>\n<\/ul>\n<p>\n    The full compatibility list on the product page covers hundreds of combinations \u2013 from TUF Gaming A15 FA507NU<br \/>\n    and FA507XI to ROG Zephyrus G14 GA402 series, G15 GA503, Zephyrus M16 GU603 and various ProArt StudioBook 16<br \/>\n    and 17 variants. If you find your exact model name there, you can order with confidence.\n  <\/p>\n<h2 id=\"step4\">4. Reviewing the product details before adding to cart<\/h2>\n<p>\n    On the product page, you will see a concise specification block. For this adapter it includes:\n  <\/p>\n<ul>\n<li><strong>Item Condition:<\/strong> Brand New<\/li>\n<li><strong>Color:<\/strong> Black<\/li>\n<li><strong>Input:<\/strong> 100&nbsp;\u2013&nbsp;240&nbsp;V, 50&nbsp;\u2013&nbsp;60&nbsp;Hz<\/li>\n<li><strong>Voltage (Output):<\/strong> 20&nbsp;V<\/li>\n<li><strong>Current (Output):<\/strong> 12&nbsp;A<\/li>\n<li><strong>Output Power:<\/strong> 240&nbsp;W<\/li>\n<li><strong>Connector Size:<\/strong> 6.0&nbsp;mm x 3.7&nbsp;mm<\/li>\n<li><strong>Package Includes:<\/strong> 1 x Asus Charger + 1 x Power Cord (fit your country)<\/li>\n<li><strong>Warranty:<\/strong> 12 Months \/ 30-Day Return<\/li>\n<\/ul>\n<p>\n    This combination makes the adapter suitable for demanding workloads like gaming, 3D rendering, video editing<br \/>\n    and software development on powerful Asus platforms.\n  <\/p>\n<h2 id=\"step5\">5. Placing your order \u2013 what information to double-check<\/h2>\n<p>\n    Once you are satisfied that the voltage, current, connector size and compatibility match, you can proceed to<br \/>\n    checkout. Before confirming the order:\n  <\/p>\n<ul>\n<li>Ensure the <strong>shipping address<\/strong> and <strong>postcode<\/strong> are accurate.<\/li>\n<li>Provide a <strong>reliable email<\/strong> and phone number for delivery notifications.<\/li>\n<li>If possible, keep a note of your Asus laptop model and part number in case customer support needs it.<\/li>\n<\/ul>\n<p>\n    The 30-day return option and 12-month warranty provide additional reassurance if any compatibility or<br \/>\n    quality issues arise.\n  <\/p>\n<h2 id=\"step6\">6. Receiving and testing your new Asus 240W charger<\/h2>\n<p>\n    When the adapter arrives, the first step is a quick visual inspection:\n  <\/p>\n<ul>\n<li>Check that the housing and cables are intact and undamaged.<\/li>\n<li>Verify that the connector is the expected 6.0&nbsp;mm x 3.7&nbsp;mm barrel plug.<\/li>\n<li>Confirm that the label on the adapter shows 20&nbsp;V and 12&nbsp;A output (240&nbsp;W).<\/li>\n<\/ul>\n<p>\n    For the initial test:\n  <\/p>\n<ol>\n<li>Connect the mains power cord to the adapter and plug it into a wall socket.<\/li>\n<li>Insert the 6.0&nbsp;mm x 3.7&nbsp;mm connector into your Asus laptop\u2019s DC-in port.<\/li>\n<li>Check that the charging LED on the laptop and\/or power jack lights up as expected.<\/li>\n<li>In Windows, confirm that the battery icon now shows \u201cplugged in, charging\u201d.<\/li>\n<li>Optionally, run a short gaming or rendering session to verify that the laptop remains stable under load.<\/li>\n<\/ol>\n<p>\n    If everything works correctly, you can confidently retire the damaged or under-powered adapter.\n  <\/p>\n<h2 id=\"step7\">7. Daily use and care of a 240W Asus power adapter<\/h2>\n<p>\n    A 240&nbsp;W charger is a high-power device and benefits from a few best practices:\n  <\/p>\n<ul>\n<li>Place the power brick on a hard surface with good airflow; avoid covering it with blankets or bags.<\/li>\n<li>Avoid sharp bends at the point where the cable meets the adapter or the laptop connector.<\/li>\n<li>Unplug by holding the plug, not by pulling on the cable.<\/li>\n<li>Use a surge-protected outlet where possible, especially in areas with unstable mains power.<\/li>\n<li>When travelling, coil the cables loosely and avoid crushing them in a tightly packed bag.<\/li>\n<\/ul>\n<p>\n    Following these practices reduces stress on the connector and internal components, extending the life of<br \/>\n    your new 240&nbsp;W adapter.\n  <\/p>\n<h2 id=\"step8\">8.
