I already have an EVGA 80 Bronze PSU but doesn’t provide enough amps on the 5v rail which is why i’m going for a period correct PSU. Can’t find Antec PSU’s with enough watts. Guess it’s good to use this old psu until i have enough to buy the Corsair TX850M 80 Plus Gold PSU.
The RM850x has 150W combined on 3.3V and 5V rails . The TX850M only has 130W . The official price difference is 20 US$, so I would recommend the RM850X .
EDIT: These models now come with a 24-pin ATX connector that does not allow detaching the extra 4-pin block for use with a motherboard equipped with a 20-pin ATX connector . An adapter will be required will be required for use with most older motherboards. I use an RM850x and Startech adapter cable on my main retro build .
Looked into it and the TX850M looks like the clear winner. Giving 50Amps on the 5volt rail where as the other Corsair PSU you mentioned only gives 25Amps on the 5 Volt Rail. The Magna that i baught sucks. Isn’t providing enough power to the GPU.
How can you have 50A on the 5v rail, which would mean 250 watts, if the max combined load on 3.3v and 5v rails is 130 watts? There has to be a typo somewhere, or there is something I am missing.
EDIT: The manual from the Corsair web site says 25A for the 5v, which makes much more sense .

EDIT : Found the source for that "50A" reference : https://www.eteknix.com/corsair-tx850m-power-supply-review/ . They also have a box photo where you can make out 25A for the 5v rail . They reviewer either made a typo or was provided documentation with a typo and since, nowadays, people mostly care about the 12 rail, no one noticed .
There was also what is likely an older version of the TX850M (PSU "manufacturers" love revising their designs and specs without adding version numbers) with 30A max on the 5V rail and 150watts combined for 3.3v and 5v. It had a bronze efficiency rating, though. https://www.newegg.com/corsair-enthusiast-ser … N82E16817139029
