Grigori Posted December 2, 2013 Share Posted December 2, 2013 The system containing the HX-750 was assembled in May 2012 and has been completely stable and unmodified since the initial build. Last week I began to notice a vibration in the case that got progressively louder over the course of a couple of days. The noise would cycle in intensity over the course of several minutes and I was able to trace this to the cycling of the power supply fan. This was occurring even under light usage where the system is only drawing about 145 watts. Since audio and video editing is one of the primary uses of this machine, quiet is very important. In response to the noise problem, I purchased an Obsidian 550D case and was planning to transfer the system to this case tomorrow. Earlier today, however, I suffered a complete power failure, no BSOD, just instantly dead as if the system was unplugged. Power is supplied through a 1350 VA sine-wave UPS which is in good working order. Initially, the system would not restart, but after cycling the PS power switch I was able to get the system restarted. Looking at user comments at Newegg and Amazon, there appears to be an unusually large number of complaints on early failures of the HX-750. I've always had good luck with Corsair (I have a VX-550 that's run for many years), but I'm not sure which way to go with the current system.
