This harness carries power between the power supply and the mainboard and is critical for stable startup, normal operation, and noise suppression. Damage to this cable-such as broken conductors, heat stress, bent pins, connector damage, or a missing ferrite core-can result in intermittent power issues, no-power conditions, random shutdowns, or failure to boot. The harness plugs directly into CN501 on the mainboard, providing a factory-correct, direct replacement with no splicing or modification required. The ferrite core helps suppress EMI and voltage noise commonly generated by switching power supplies. Compatible with Epson ET-8550 only (compatibility with other EcoTank models is not confirmed). Installation requires opening the printer and accessing the power supply and mainboard area; basic technical skill is recommended. This listing includes only the power supply wire harness and does not include the power supply, mainboard, or any other internal components beyond what is shown.\u003c\/p\u003e\n","brand":"BCH Technologies","offers":[{"title":"Default Title","offer_id":53020633432371,"sku":"AS-ET8550-WirePS","price":19.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0751\/5648\/8499\/files\/865d274f-9f80-54db-999e-9ab96b2430ff.png?v=1770134522","url":"https:\/\/bchtechnologies.com\/products\/epson-et-8550-power-supply-wire-harness-red-3-wire-with-ferrite-core-cn501-mainboard-connection","provider":"BCH Technologies","version":"1.0","type":"link"}
