Is it okay to use cheap power supply?

Are used power supplies OK?

Can a bad power supply damage a motherboard?
Yes, it can. If you just lose one of the voltages it will probably be ok as the motherboard may just stop working, waiting for the right voltage. A power supply can also fail by putting out partial or over-voltage. Either of those can cause motherboard components to overheat or even explode.
How do I know if my PSU is still good?
The Answer
- Plug the power supply into the wall.
- Find the big 24-ish pin connector that connects to the motherboard.
- Connect the GREEN wire with the adjacent BLACK wire.
- The power supply’s fan should start up. If it doesn’t then it’s dead.
- If the fan starts up, then it could be the motherboard that’s dead.
Why should you not cheap out on PSU?
PC parts should never be chosen with respect to futureproofing. And the reason that the PSU is the number 1 component to not cheap out on is because a cheap PSU with group regulation and bad protections could potentially bring other components with it when it fails, while no other component has that capability.
Should you buy an expensive PSU?
The price of the PSU scales with how much power it can output (in watts). PSU’s with an 80+ efficiency rating will also be more expensive and the price will scale with level of rating (bronze-platinum). So yes in a way the most expensive PSU’s will perform better in power output and efficiency.
Can you sell power supply?

Plus, PSUs now are more efficient both power-wise and heat-wise, and will be quieter and cost you less in electricity bills as a result. That’s the thing. I wanted to do a new build soon, but life does what it does and financially I just don’t see it happening for a couple of years at least.
