Got a new desktop (Second-hand from an acquaintance that built it himself) and I was told beforehand that the PSU was probably not strong enough. I've listed the specs of the desktop to the best of my abilities in my profile specs so my question is what strength of PSU will I be needing to ensure I have no problems in the future. So far I've experienced a few issues (I'm not 100% sure it's down to the PSU) - occasionally even when not doing anything intensive my monitor will go off, followed by the keyboard & mouse sometimes - audio keeps playing but then becomes torn and goes off as well - the desktop itself keeps going but it either resets itself or I'm forced to do a hard-reset. It's happened on start up, 20 mins in and in rapid succession but then other times it's ran for 6 hours straight with no problems.
Summary: PSU Suggestion and if the lackluster PSU I have at the moment is indeed the cause of my problems.
(It may be a day before I can respond to this but rest assured I will as soon as I can)
Thank you in advance for any help/advice/suggestions.
