For Christmas I got a new PSU and was told by someone here that to use it with my Dell Optiplex 980 I would need to buy an adapter and rewire it to work properly due to the MOBO's proprietary connector. (Link to the forum he/she provided: http://) However, after inspecting the PSU again I have found that it's MOBO connector has 24 pin's, while the end of the adapter it would plug into only has 20 (this being bought from a link in the form in the above link I have provided) will this affect its prformance? In case it is relevant, the PSU is a Thermaltake Smart 650W.
