Seasonic Replacement for a dead PSU - Simple swap?

platypus · 6 Jun 2022 at 11:35

I have a Seasonic PSU from somewhat of a bygone era, think its ~10 years old. Its an 80 Plus Platinum SS-860XP(2), so assume 860W active PFC f3, if those mean anything. Its got a modular front to connect mobo components to as needed rather than having all the cables in.

This blew this morning, and is now dead. I was wondering about replacing it, with a new seasonic - happy with the brand - the similar 850 is out of stock so perhaps the 750 will be sufficient? I was hoping by purchasing the same basic supply i can just replug in the ends rather than having to recable up my entire PC? I've got a Geforce 1080 Ti, 1TB ssd, and 64GB of DDR3 ram with an I7 in an ageing motherboard. I'm not likely to upgrade anytime soon (not allowed to

) so I don't think I need anywhere near the 860W (I was running 2 cards at one point which is why I think I had such a high one).

Was sort of thinking about the https://www.overclockers.co.uk/seas...-platinum-modular-power-supply-ca-07a-ss.html.

TIA.

I'd double check with Seasonic that the cables with any new PSU are interchangeable with your older PSU. I know Corsair have changed cables over the years, and you cannot just swap
without checking compatibility. You wouldn't want to release the magic blue smoke!

Ah thats a real shame but a sensible suggestion

As above you can't risk it as OEMs have different suppliers for similar products so they can change the PSU end pin out at any time.

Seasonic has changed cabling/connectors at least once since their first modular PSUs.

The very first Seasonic X650's had different motherboard / CPU connections to newer Seasonics, however Molex and SATA connections were the same. My current Titanium Prime is using a Molex connection from a 2009 X650. I did this as I considered the older cable better quality, thicker copper & outside braided, then the newer one, it was the cable going to my Asus STX II.
