I bought this prebuilt computer
(Norwegian site, use google translate to see parts)
I already own 2 SSDs, thought I would put them in. Connected them to the PSU and motherboard with SATA. I give the computer power and try to boot. The computer makes a slight sound but no indication that it was going to boot up.
I thought one of the SSDs was faulty so I tried to connect with only one, it did not work. I disconnect everything so it's stock and it boots up like normal.
I read in an article this might be because of lack of power, but my PSU is a 750. I do a have a demanding graphics card though (1080Ti).
The computer stock has a Samsung PM961 SSD 512GB M.2 NVMe & a Seagate Barracuda 1TB 3.5'' HDD
