devonsteele Posted February 26, 2020 Share Posted February 26, 2020 Hey Everyone, It looks like my power supply is bad (and/or to weak) and I am trying to find a new one. It looks like in my computer it is the sf400 model which they do not make anymore. I am assuming I could get the "newer" SF450? Is there a stronger one that I can get thats more like 600 or 750 watts? Does it matter which model I get as long as the size of the unit fits in the case? Thanks for any help!

zguy85 Posted February 27, 2020 Share Posted February 27, 2020 (edited) Same. Mine is also starting to wear. What is the best the best option for replacement ladies and gents? Probably also will go with the sf450 also. $110 on Amazon Edited February 27, 2020 by zguy85 Link to comment Share on other sites More sharing options...
OneOwnerSydney Posted March 7, 2020 Share Posted March 7, 2020 You can swap out the original PSW with a Corsair 750 SFX. I have recently gutted my i7-7700k Pro system and upgraded everything. Link to comment Share on other sites More sharing options...

Corsair Employee Corsair CJ Posted April 3, 2020 Corsair Employee Share Posted April 3, 2020 SF600 or SF750 would be solid off the shelf replacements for the PSU we provide in the older Corsair ONE models. We do not officially support such upgrades though, but there may be tear down guides online that could serve as a reference. The PSU is buried pretty deep in the system on the CPU/motherboard side of the enclosure. There'll be quite a few cables in the way, thankfully we use essentially the same layout for our SF-series parts so you wouldn't run into issues with cable length on the new PSU.
