It could be a cable, of course, but I'll switch out the cables just in case. 661-5449 Apple Power Supply 980W for Mac Pro 2009 - 2012 - Refurbished Where used: : Mac Pro (Early 2009), Mac Pro Server (Mid 2012), Mac Pro (Mid 2012). It seems clear that it is not the Logic Board, and I don't think it's the Mini-Display card on the CPU. I'm ready to open the display up and the question is if you guys agree that it's probably the power supply board that needs to be replaced, or if it's something else that I don't know about. Having only one display, switching out is not really an option here. There are multiple part numbers but all are compatible with all A1289 Mac Pro. 512GB Solid State Drive SSD Mac Pro Mid 2010 A1289 MC561LL/A MC250LL/A for 2.8Ghz 3.2Ghz 3. Leaning over the CPU, I hit something (maybe the desk, maybe the cables?) but the display came on. 980w Apple OEM power supply for all Mac Pro A1289 models, 2009, 2010, 2012. Power Supply 980W 614-0454 DPS-980BB-2 MB871LL A1289 Mac Pro Early 2009. no display, no sound, no shhhhh, and my iphone connected to the USB port was not being charged. So I pulled out the plug and reinstalled it after some time, and nothing. The display was making a white noise "shhhhh" sound for the last couple of days including after I shut down the CPU, the display was continuing to make this noise. I have a 2010 Mac Pro w/ 27" LED Cinema Display where it seems the power is going out intermittently. Power Supply 980W 614-0454 DPS-980BB-2 MB871LL A1289 Mac Pro Early 2009.
