 | I semi-accidentally ended up with 2x 3090's and they didn't fit into the case I had, so I went to the local e-waste store and asked for the most obnoxious huge PC case they had, and this is what I got. That vent on the side is for a 200mm fan! I've stuffed my setup in there, but with only one of the 3090's as I need to find a bigger PSU that can feed both cards. What PSU are you other dual 3090 users running? [link] [comments] |
My whole life I've liked small PC's, until I needed more GPU.... What PSU are you guys with dual 3090's running?
