First of all I just put the third PSU in my server due to failure. None of them were cheapies.
The first was an Enermax EG465P-VE. It died after approximately 3 months of use. One hell of a short life. At the time it was only running 3 drives.
The second was an Antec True 480. This time I got 5 months with 4 drives running.
Now I am on a Vantec Stealth 470. I hope this time I get a little more life, but I also added another drive for a total of 5 in my server now.
So my question is, do I need better case flow, or just a better case period. The server is housed in an ancient Antec full tower case. This is the only thing I can think of that is killing these PSU's. However I think or thought the precautions I took would be adequate for cooling. Maybe I just need an even better power supply(PC Power and Cooling), if I want to run this many drives 24/7?
For a side note, when they died, they didn't die completely. The first one would make me flip the switch off for 30 seconds then back on and it would boot. The second was playing hell with spinning up my drives on boot. In fact the second made me think I had HDD failures this time, but I couldn't see more than one drive going at the same time. I was right because with the fresh PSU it boots like a dream.
