If power is confirmed, the PSU's internal fuse may have blown, or the Over Current Protection (OCP) has tripped due to a short circuit on the motherboard or a hard drive. Disconnect all DC cables from the drives and board, and test the PSU with a basic ATX tester or by bridging the PS_ON pin to ground to see if it powers up bare.\u003c\/p\u003e\r\n    \r\n    \u003cp\u003e\u003cstrong\u003e2.

A 200W power supply will only draw as much power as the system demands. Upgrading from 150W to 200W gives the system more \"headroom,\" allowing the power supply to run cooler and potentially extending its lifespan, provided the physical dimensions and connector pinouts match the original unit.\u003c\/p\u003e\r\n\r\n    \u003cp\u003e\u003cstrong\u003e3. The power supply fan is making a loud grinding or whining noise.\u003c\/strong\u003e\u003cbr\u003e\r\n    The internal 40mm cooling fan utilizes bearings that can dry out or wear down after years of 24\/7 operation in dusty environments. While the PSU may still be delivering power, a failing fan will eventually lead to thermal shutdown or catastrophic capacitor failure due to overheating. It is highly recommended to replace the entire PSU immediately to protect your data storage.\u003c\/p\u003e\r\n\u003c\/div\u003e\r\n\r\n\u003c!-- Structured Data --\u003e\r\n\u003cscript type=\"application\/ld+json\"\u003e\r\n{\r\n  \"@context\": \"https:\/\/schema.org\",\r\n  \"@type\": \"FAQPage\",\r\n  \"mainEntity\": [\r\n    {\r\n      \"@type\": \"Question\",\r\n      \"name\": \"Why is my server power supply not turning on?\",\r\n      \"acceptedAnswer\": {\r\n        \"@type\": \"Answer\",\r\n        \"text\": \"Check the AC power source and cable first.
