I have an OCZ ModXStream Pro OCZ700MXSP 700W PSU I was using to power an older Abit IP35 pro socket 775 motherboard. It has been working without issue for over a year, with moderate (1-4 hours use per day max). Thursday evening last week it would not boot after being used just several hours earlier. It would cycle on and off with NO video display. The motherboard lcd would cycle up to 8.3, then change to CC, which represents the CMOS Clear switch is depressed (which was not). I did some various troubleshooting, thinking it was a motherboard problem. Removing the 8-pin cpu plug resulted in a slightly different lcd boot number result (several steps farther in the process), but still no boot or video. Finally got down to the PSU and switched to an old Antec 400 watt I had sitting on the shelf. Had to use a 20-24 pin ATX cable adapter and a 4-8 pin CPU cable adapter. The system booted just fine and has been running without problem since.
I took the OCZ PSU out of the case and hooked up a single hard drive for load and followed the instructions at the OCZ site to check the voltages. All voltages seem fine. Moved the OCZ PSU to an old system and again the system will not boot. No Video. Before I initiate the RMA process, is there anything else I should be looking at to isolate/identify the problem? Thanks for your input. Jim Maki [email protected]
