Sony PCV-R549DS Power Supply
The PSU, or power supply, is responsible for powering the motherboard, CPU, hard drive and other components that need power. Always try to replace a PSU with at least the same watts, if not bigger. You do not always want to go with the cheapest PSU as it is the only thing between the power coming from your wall and delicate components inside your Sony. It is a pretty straighforward job to install a power supply in the PCV-R549DS desktop. Purchasing a new Sony PCV-R549DS PSU is easy if you have access to the old one for comparison.
Major signs of a faulty main power source
- Computer refuses to power on
- You sense burning plastic inside the PSU of your Sony
- System shuts down while processing a taxing load
