January 4, 20197 yr I have a home server which I use for UnRaid. I also have a VM running on the server for when I want to play games. Yesterday I had a few issues where by two of my USB ports weren't working. They weren't working in the BIOS nor were they working in O/S. Tried various things to get them up and running, but didn't have much luck. I have just pulled the server out of the cupboard to see if I could diagnose the issue as my first thought was perhaps the ports were damaged. Looking at them carefully they seem fine. So my next instinct was that perhaps my PSU isn't supplying enough power? To give you an idea of the build here is what I have: Motherboard: ASUS-WS/IPMI CPU: Intel i7 5820k RAM: 2 * 8GB HyperX Fury GPU: Inno3D GeForce GTX 1070 iChill Air Boss X3 SATA Cards: 2 * LSI SAS cards M1015 HDD: 3 * WD Gold 10TB, 16 * WD Red 3TB, 1 * Samsung 950 EVO 1TB CPU Cooling: Corsair H105, 4 * Fractal R3 140mm fans, 9 * Fractal R3 120mm fans USB: Flash Drive, Keyboard, Mouse At the moment that is all running off this PSU: Seasonic X-Series X660. (660W) Today when I took the server out I disconnected all of the drives and the USB ports started working again which I think confirms my hypothesis that I need a more power PSU installed. However I wanted to check that I have some level of agreement before I start pulling out all of the power cables and installing a new PSU, is there anything else I should consider?
January 4, 20197 yr Author Ok, I had a Seasonic Prime Gold 1000W which I had been planning to sell which I have just put in the server, everything seems to be working again now though so fingers crossed problem solved.
