Topic: is 1250w psu + 1000w psu enough for 6x r9 280x ? (Read 1073 times)
2x 1000W is enough, take PSUs 80+ Gold for sure
I would say that 1000W + 850W should do the work.
The powered riser should connect to the main 1250W PSU if you do not want cut the 12V lines on the riser.
In this case, 850W for the 2nd PSU is enough if you undervolt. Some 280X cannot be undervolted.
Make sure the 850W PSU is single rail.

an 850w for the other 3 cards is enough
Yes but you must separate 12V lines from two PSUs . Meaning you must have 3 molex risers with 12V lines cut so that the new PSU only powers the three new cards. Without separating 12V lines PSUs might start to oscillate and break.
But be sure to undervolt cards!
