The laptop ships with a 240W brick because peak CPU + RTX GPU draw approaches that figure. A 200W adapter will physically run the machine and charge it at idle or light use — and many sellers note the 240W unit can \"replace 200W\" for that reason. But the substitution only works one direction: a 240W brick safely covers a 200W requirement, \u003cstrong\u003enot the reverse\u003c\/strong\u003e. Run heavy gaming on a 200W supply and the GL66 throttles the GPU to stay within budget, and the battery can discharge even while plugged in. For full, sustained performance, match the original 240W rating.\u003c\/p\u003e\n\n  \u003cdiv class=\"callout\"\u003e\n    \u003cstrong\u003eDirection matters:\u003c\/strong\u003e a 240W adapter can replace a 200W one on the same 20V system — going the other way (200W on a 240W laptop) costs you performance under load.\n  \u003c\/div\u003e\n\n  \u003ch2\u003eWhy 20V is the non-negotiable number\u003c\/h2\u003e\n  \u003cp\u003eWattage affects how hard the laptop can run; voltage affects whether it's safe at all. The GL66 expects exactly \u003cstrong\u003e20V DC\u003c\/strong\u003e. A higher voltage risks the charging circuit; a lower one usually means no charge. This is also why you can't reuse an older 19.5V MSI brick here — check the decimal on the label, not just the wattage.\u003c\/p\u003e\n\n  \u003ch2\u003eThe spec at a glance\u003c\/h2\u003e\n  \u003ctable\u003e\n    \u003ctr\u003e\n\u003cth\u003eBrand \/ Model\u003c\/th\u003e\n\u003ctd\u003eChicony A20-240P2A\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eCompatible part numbers\u003c\/th\u003e\n\u003ctd\u003eA20-240P2A · A240A010P · ADP-240EB D\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eOutput\u003c\/th\u003e\n\u003ctd\u003e20V DC \/ 12A \/ 240W (replaces 200W)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eInput\u003c\/th\u003e\n\u003ctd\u003eAC 100–240V, 50\/60Hz (worldwide)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eBuilt for\u003c\/th\u003e\n\u003ctd\u003eMSI Pulse GL66 12UGK \/ 12UGKV-464\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eIn the box\u003c\/th\u003e\n\u003ctd\u003eAdapter + US power cord\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth\u003eCondition\u003c\/th\u003e\n\u003ctd\u003eBrand new, original OEM\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\n  \u003ch2\u003eWhat the safety protections do\u003c\/h2\u003e\n  \u003cp\u003eGenuine Chicony bricks include the protection circuits cheap clones often omit.
