Replaced ModXstream 700w PSU with new Antec 850w PSU because I was missing several cables for old modxstream (gifted from a friend after old corsair 500w failed) but for some reason continually get the "no boot device found" message.

Using a gigabyte b85m-ds3h mobo.
It worked with my friend's SSD which acted corrupted (granted it hasn't been used in years and booted into windows before crashing).

Worth mentioning my HDD worked before.

Already tried re-seating ram and ensured the proper connection of the larger cable (28-pin?) that runs from the PSU onto the CPU. The PSU came with an internal cable that runs from the psu to be connected to the CPU's 2x4 pin slot, but also a separate cable that says CPU on it that needs to be connected to the PSU manually. Any ideas?
