I may need to replace the power supply in my Antec Sonata. The unit has been inactive for over 2 years. I just set it back up and it will not turn on. Is it likely the power supply is bad? How can I be sure?
You can even install a CORSAIR CX400. It's much better than yours (TRUE380S). It won't have any problem at all to handle your system. It's a quality PSU. Anyway, if the money is not a problem for you, the VX450 is a bit better PSU, but for your system I recommend you to go for the CX400.
Install it with the fan pointed down. There is no problem at all.
