Seasonic / Corsair PSUs and Cables.

[RyanTMatt]

For a build of mine, I am either choosing the Seasonic PRIME 850W, or the Corsair 850 RMx. Both are fine, it is just a question I need answering. I will be using black/white cables for these and I'd like to know about Corsairs' Individually Sleeves PSU Cables Pro Kit. Do these cables go into the 850 RMx itself or do they connect to the PSU's cables?

They go into the PSU, they are not extensions.

That said, you could (and should IMO) get extensions, I have those cables and they're... fine, but kind of cheap

Thanks for the help!

Nah, way better to just buy a cablemod kit.

Far nicer than plugging extensions into the already longer than necessary PSU cables.

No. Why?  WHY!??!  Why would you suggest that?!?!

 

When you can get proper cables that replace the stock cables, why would you ever consider buying extensions?

 

Extensions:  

 

* Make the cables longer and more difficult to hide.

* Add an additional connector that creates resistance, which results in voltage drop

* Makes the cables longer, which creates resistance, which results in voltage drop

That's fair although Cablemod is more expensive and good extensions would be in the same price range the Corsair cables iirc

It's an absolutely insignificant difference in resistance, nothing that will even be noticeable.

The main issue is the consistency/reliability of connection, since another connector adds another point of failure or disconnection.

You're saying the same thing I am.  The pins are always the weakest link.  If the pin is not securely connected, what happens?  You increase resistance and cause voltages to drop.

 

You see burnt pins even when extensions aren't used.  Why do you think it's a non-issue?

Fair enough.

I don't really have any budget on this, I can buy whatever's needed. If chosen the Seasonic PRIME 850W 80+ Gold PSU with Black/White Cablemod Cables to plug into the PSU, no extensions. The color will fit my build perfectly and won't be harder to cable manage. @Enderman @orbitalbuzzsaw @jonnyGURU Thanks for all the help!

I think you're both on the same page.

 

Enderman was just more stating potential connector issues beyond 'resistance.'

 

I am well aware that's what you mean by resistance, read much of you work, but not everyone's mind goes to that.

 

So badly mated or incorectly inserted, tarnished/corroded, loose pins/sockets, crimp or solder failure of the termination and so on.

 

Not everyone's mind goes to that, they just think, "oh that 0.1R difference at the connector is nothing" if you mention resistance.
