I see you voted me down. You wouldn’t take a Seasonic Focus Gold 1000w over the RMx for $40 less? Seems like a no brainer.
I have noted a custom builder over at Amazon has had multiple failures with the RMx line, citing a 40% failure rate. But overall, the line is highly rated by customers.
It's a bit of a tossup. I love my Focus Plus 850 Platinum. I also owned a Corsair AX850 which has been rock solid. I'm trying to decide between two 550W RMx or two Focus Plus 550W now. (For a small unraid server and pfsense box)
They are both good units. Both come with an excellent warranty. But the RMx is slightly better on the rail output when stressed.
Seems all the decent units have sky rocketed in price over the last year. I wonder if there is a shortage or component cost increase.
