Hi All

I have a few questions regarding some upgrades I intend on making to my system.

Currently (as in the sig) I have my C Drive as a 250GB SSD.
I intend on wiping my entire system and fresh installing Windows 7, to get rid of the junk that has accumulated over the past year and a half. (Stray files and my OCD do not mix well)
I have an MSI X99 Sli Plus MB, which supports M.2 at x4 speeds. I want to get an M.2 SSD - will I encounter issues installing Windows 7 to this as a boot drive? I have read numerous issues with M.2 not functioning as boot drive, but none specific to the X99 SLI PLUS. Also, do I need to worry about NvME VS AHCI? Should I be opting for one over the other?

I also intend on having 3 GPU cards in the system, the current GTX980 & GTX750 TI with the intent to buy a GTX980Ti. SLI is not my concern at all, as I am using this for Octane Render rather than gaming. I have read that having 3 GPUs in this system, as well as an M.2 should not throttle any of the speeds, (I am using the 28 lane 5820K CPU) though I may be misinformed. Can anyone confirm?

Finally, for all 3 GPU's to run I am considering a new PSU, a 1000W to replace the 750W I have, to ensure I have enough to run the system? Is this overkill? Is it even necessary? Will the current PSU I have be enough to power the system I intend on upgrading to?

Any feedback on any question would be hugely appreciated.

Thanks!
 
Solution
seen people on overclock.net forum with same motherboard saying it boots fine off m2 drive

though they didnt say nvme m2

and did say make sure you have the latest bios just to be safe
