Lenovo 3000 7818 Power Supply
It is usually pretty easy to install a power supply in your Lenovo computer. Never go with the cheapest power supply because it is an important barrier between the power coming from your wall and delicate components inside your Lenovo. Purchasing a new Lenovo 3000 7818 PSU is quite simple as long as you have the old one to measure, size-wise. The PSU, or power supply, is responsible for powering the computer. It is always a good idea to replace an old power supply with a similar wattage or bigger.
What to see if the PSU is crapping out?
- You notice smoke in your power supply
- System shuts down while under a heavy load
- The PC refuses to turn on
