Updated my gaming system today. Fitted a new TUF Gaming Z490-Plus, i7-10700k CPU & 32gb memory. Having some issues. First one: The CPU power on this new board has 8 pin & 4 pin sockets. My current PSU only has the 8 pin, so will have to update that. However a browse on the forums suggests it's not necessary unless running 32gb or more of memory, or overclocking.
Second issue: Bit more serious. System wont boot into windows. Starts fine in bios & shows my 2 SATA data drives & the M.2 with the OS on it. But if I go to Boot Priority, it says "The system couldn't find any bootable devices" Thinking there may be an issue with the M.2, I tried another hard drive with a working OS on several of the SATA ports. No joy at all. I will order another PSU anyway but somehow don't think that will solve issue No 2. Any help or advice appreciated. Thanks
