PSU Extensions Bad?

post #1 of 4
Thread Starter 
Just out of curiousity, does adding an extension to a PSU lead like the 8-pin or even the 24-pin have any negative effects? I've heard some people say they won't use modular PSUs just because the extra connection has some sort (can't remember now) of adverse effect.

If you are talking about just extensions, there's nothing bad about them. There is a lot of BS out there about PSUs (most of it originating from PC P&C), and modular PSUs perform just as well as normal PSUs and the added connectors add marginal resistance (similar to lengthening the wire a little bit). Extensions are similar, just adding a couple connectors and as long as they are secured properly, you will get no noticeable increase in resistance and the accompanying voltage drop. Now things like 20->24 pin and 4->8 pin CPU adapters aren't a good idea since they do add noticeable resistance and many times the mobo will work without the adapters.

Very good then! Thanks!

PCP&C was spewing forth "Don't buy modular PSU's (only buy ours!)" for a long time since a lot of them were high-resistance connectors. Since then, they've improved on the design and offered more surface area on the contacts, which alleviates the resistance issues, and is of a negligible concern at this point. Adding extensions is fine, just make sure they are made well. And DON'T buy 20-24 pin adapters, or 4-8 pin adapters. Very dangerous.
