On the component side, not on the PSU side.

Suggesting people to keep their cables while not knowing what PSU they are changing from is wrong and you should definitely not suggest that.

 

To OP: as said above, the PSU side of the cables is not standard, meaning one PSU can have the voltage/ground on another line as compared to another.

I would highly suggest changing out the cable for the new ones that comes with the new PSU.

Hey guys,

 

last year I build a new PC which has a 550W PSU. For the new RTX 3080 I obviously needed a new one.
Thats why I bought myself a thermaltake toughpower gs with 1050W.

What i was wondering... i dont actually need to replace everything and do a whole new cable management, do I?
Couldn't i just plug all the cables out of my old PSU and plug them back into my new one (both are modular)?

I mean, in my mind, this makes sense as they are only cables.. but i wanted to make sure, therefore this post :D

Thanks in advance!

No. All cables are different. You HAVE to make sure the current cables are wired the same and are compatible with the psu you have. If not your system will literally go up in smoke.

It is not. Not at all. Sure the connectors on the board are but the connectors on the psu differ a lot. Like literally same series psu's when comparing the new version to the old one can have a totally different psu layout.

The atx end (the one that plugs into your components) is standard, the PSU end is NOT, one psu could have a different pin layout than the other and it's not standard, unless you're 100% sure they have the same pin layout (since we don't know what 550w unit that is) don't use the old PSU's cables, just use the ones the came with the new one.

so, the safer way would be to replace everything?

THE way, not the safer way, unless you're sure that the cables are interchangeable between the two units, though without knowing what PSU you were using until now, we can't help you with that.

The safest way is to check compatibility. If it's a no or even a maybe then do not use the current cables and just use what comes with your psu.

 thermaltake toughpower gs with 1050W.

Is this some ancient thing i can't find nothing about ?

No. Unless you're absolutely sure that cables between the two PSUs are interchangeable, which is rare even inside the same brand lineups.

Tag or quote me so i see your reply
