Following the lead of LtCmdrPAC I investigated and performed GPU upgrade of Corsair One Pro Plus 2018 edition GPU to...Asus RTX 3090 Turbo. Notes: - The Corsair One Pro Plus 2018 edition is very similar to 2017 with minor differences (e.g. there is no white retaining clip on the PCIe extender). This LtCmdrPAC post was thus extremely useful - doubt I would have dared or done it without! - The back and front plates use plastic retaining clips, which seem quite fragile. I lost a couple on the back plate despite greatest of care - fortunately the four remaining were still sufficient for firm mounting on reassembly. - I found it best to temporarily remove the Displayport/HDMI port block at the back while removing/inserting GPU into the PCIe extender. - Power supply had already been replaced with a drop in Corsair SF750 80 PLUS Platinum (the factory SF500 failed a year ago for no good reason i.e. before any of my upgrades :( ). - The Asus RTX 3090 Turbo is supposedly the same 268mm length as LtCmdrPAC ZOTAC RTX 2080 Ti Twin Fan but at first didn't fit by less than 1mm interference with the bottom support ledge mentioned by LtCmdrPAC. Luckily the screws holding the ledge to the frame near the mains inlet can be loosened allowing the ledge to move a little down before retightening (it's not clear from LtCmdrPAC images whether such screws exist for the 2017 edition?). - The GPU PCIe power cables are just long enough to reach the back of the Asus RTX 3090 Turbo where the power sockets are and the gap to the bottom of the case is just enough to accommodate the plugs there. - The biggest problem is the Corsair One internal Displayport/HDMI cable lengths, which are exact only for the factory card. The front HDMI cable cannot reach the ASUS HDMI port at the back and the rearmost Displayport cable cannot reach even the rearmost ASUS Displayport. Small high bandwidth extension cables were required. BTW I found the Corsair One internal HDMI cable/socket for the front is not great for 4k 60Hz HDR (the ASUS and HDMI extension are ok without) - I'm looking into how to fix that. I suspect the Displayport cables/sockets are similar quality - it is well known the internal Displayport to HDMI converter at the back cannot do 4k 60Hz. - Had already upgraded the top fan to Noctua NF-F12 iPPC 3000 PWM some time ago for better cooling of the CPU under load. Reconnected via extension to System Fan connector on the motherboard and fan curves set accordingly to CPU temperatures. System runs great and fast. Silent on the desktop but of course it blows hard under VR, 4k gaming and AI Video Processing - unimportant under headphones.
