Hey guys, my new mobo came today, it has a 24 pin slot(probably not the correct name) but my psu only has a 20 pin cable, simple question, is this safe?
It's safe - electrically, but probably won't work properly. Either you'll need to get an adapter to convert one of your molex plugs into a 4 pin plug, or get a new PSU with the correct 24 pin connector.
