Hey there,could you post make and model of your computer please.

 

Have you checked incase it is just a loose fan?

 

When did you last clean your computer internals?

Hi, I will also add, PSU (Power suplly units) are pretty much standardised these days as far as fittings and connectors though there are some small differences with number of connectors and type of connector, plus bigger units can be slightly larger physically, however the important thing is the power it can handle in watts (W in the spec).

It is usually a good idea to go for one of a higher rating when doing a replacement of an existing one, as most manufacturers fit one that is just adequate for the job.

In your case your existing PSU is rated at 650W so a 700W or 750W unit will give that extra bit of headroom if you wish to install something more power hungry, such as a basic graphics card at some time in the future.

If you can tell us some more about the computer and its mother board, though manufacturers model number should be enough, we can be a bit more specific as to recommendations.
