A buddy wants to upgrade his PSU from an SF750 to a 1000w SFX/ SFX-L. The reason is he upgraded from a 3070 Ti to a 3090 Ti and wants peace of mind. I got some good advice in another post on whether he even needed to upgrade the PSU and ultimately my friend decided he wanted to upgrade it. e9: FSP group PSUs available as of late November 3rd US PST.
