Sony VGC-RB40 Power Supply
Purchasing a new Sony VGC-RB40 PSU is quite simple as long as you have the old one to measure, size-wise. The power supply in your Sony desktop is in charge of distributing power to the different pieces of hardware within your desktop. Always try to replace a power supply 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 high amounts of electricity and your delicate computer hardware. It is a pretty straighforward job to install a power supply in your Sony computer.
Main clues the main power source is going to die
- The Sony will not start
- You see burning plastic inside the PSU
- System shuts down while under a heavy load
