Question about Corsair RM1200x SHIFT 80 PLUS Gold

Yes, you can generally use the power supply unit with any standard motherboard. The decisive factor is the connector, which is almost always 24 pin ATX. However, I would be surprised if you need a 1200W power supply with the motherboard. I would optimise the config a little so as not to throw hard-earned money out of the window unnecessarily. Also note that this power supply has the plugs on the side. This is not usual.

Alright thanks for the help i have recently given my pc a few upgrades but my gpu 1080 gtx keep now after about 7 years it is slowly giving up the ghost and i wanted to get a 4080 or 4090 and to be on the safe side i decided to get a big power supply
