Symptoms, my computer when it gets going the power will just cut, the power indicator stays lit but everything else dies, all the fans, the screens go dead it does not respond on the network (ssh connections).
It started this when I added a forth monitor to the system. Graphic card is at GTK 750 Ti, I am running all 4 monitors to have a total of 6880x1040 resolution across all 4 monitors. 2 are connected via DVI, the other 2 are connected via HDMI
Other devices on this system is a USB mouse, PS/2 Keboard, a HP LaserJet printer, speakers, a 1 TB hard drive, 1 SSD drive 256GB, a CDROM.
I have X setup to take all 4 monitors, and when I load up Chrome, sometimes I hear fans kick into high gear.
The CPU is AMD Phenom(tm) 9750 Quad-Core Processor 8GB of memory I have a 600W power supply.
I am thinking the issue is the power supply is to low, I tried the sites listed that calculate your needed power supply, and they all put me at 300W but that does not seem like enough (am I wrong)
So do I need a new power supply. Is the 600W too low? is my current 600W just to old and a new 600W would do fine (the power supply is 5 years old. If the problem is that the Power Supply is to low on wattage, what is the recommended range I should shot for the size of the power supply (in watts)
I have currently turned off one of the monitors for now (my smallest one, and it has helped but when I start to do stuff again, it can still go down.)
