R8 uses standard Dell oem psu:
"standard size of W 150mm x H 86mm (5.9" x 3.4"), where length / depth is variable which changes based on size / output etc. Their 460w is about 5.5" long while their 850 w is 7.5" long."
The corsair SF750 Platinum is a mini psu, Dimensions 100mm x 63mm x 125mm.
not sure how you would mount the mini psu in R8.
the mini psu comes with a bracket but just want to know if the cables will fit. the corsair tx650m fits but not sure if this one will work. this will be my first PSU upgrade since i want to add liquid cooling to the aurora r8
It only comes with one EPS 4+4 cable, you need two, one for the CPU header on the mobo, and a second for the GPU_PWR header on the mobo. You cannot use the included Dell OEM cables with this PSU.

Liquid cooling doesn't require an upgrade to the PSU. You can add liquid cooling if you want, you don't need to change out the PSU. The PSU option that you have (presumably 460W) will have 0% impact on whether or not you can add liquid cooling to this machine. The difference in power draw of the AIO cooler versus the OEM fan on the heatsink is de minimis, the AIO cooler may even draw less power than air cooling since Dell likes to use high current fans.
I have the 460 watt PSU but I also have another elgato streaming card in the motherboard and I use a lot of USB drives when i'm streaming or making music.
I'm basically using all the usb drives when i'm working on music like powering USB audio cards and USB MIDI out cards
I mean it won't hurt to upgrade the PSU. Depending on the GPU that you have it may be a good upgrade. I'm just saying if it's working fine in your current setup with a 460W, adding an AIO will not change the dynamics (power draw will be about the same with vs without an AIO).
The cables seem okay, if you have a 3.5" HDD you may need a right angle sata adapter, that's the only other thing I can think of.
The SFF PSU fit might look a little odd mounted when the case is open, since there is a metal box designed specifically for the dimensions of the ATX PSU. There will be gaps when it is mounted, but it's a closed case so you shouldn't otherwise notice it and I assume it should still be mountable.
I'm also adding liquid cooling soon, this PC makes a lot of noise when i'm streaming or playing games. I'm adding the corsair H60 and changing the fan in the front of the PC to a Corsair ML120 pro. I ordered a Seasonic 650 Watt Ultra Titanium power supply but the sent me the wrong one at newegg 😞 it was a platnium seasonic 550 watt PSU that I just got in the mail which I will ship back tomorrow. And I just bought the Corsair 750 platinum one. I think that small one will fit perfect since there isn't a lot of space in the R8 case and it comes with an ATX bracket
