Getting a Haswell-compatible PSU, some questions on connectivity...Help!

post #1 of 6
Thread Starter 
Let me start off by saying that I am a noob. Literally. This is my first time building.

Anyways, I got a Haswell CPU and made sure to order a low-power state compatible power supply. In this case, the Corsair AX760. I'm getting a bunch of extension cables so i can keep my build clean, and there's something I just can't wrap my head around...

How does a molex connector fit into the back of the Corsair AX760 PSU?

I just don't see how the holes match up. This is my first time, so please go easy on me if this is a really stupid question rolleyes.gif

Anyways, yeah I don't see how either of the ends of the molex extension cable could fit into the power supply. The keying just doesn't look like it's there to me... I mean for one thing, the SATA section of the PSU isn't even 4-pin, and there are a ton of 4-pin molex to SATA/dual SATA/etc sleeved cables out there. Just how much am I missing here!?

The PCI-e, 24-pin, and EPS cables are all simple enough to understand, however.

This is the way modular cables are: one end has the proprietary connectors for the PSU, and the other has the standard connectors. So you would plug the extension into the modular cable.

Couple of things.

1: return the extensions. Corsair sells fully sleeved cable sets that will work a LOT better.

2: The molex cable will go into the accessory port. The molex cable will actually two connectors on it. One side is obviously a molex connector, and the other side will have a connector that is similar to a 6 pin cable to attach to the PSU.

This is probably not the best picture to show you, but it is the best one I can find.



You can kind of see the 6 pin connector sort of hiding behind the cables.

Oh. So if I wanted to extend a SATA power cable, I wouldn't want to buy a molex-to-SATA cable, but instead just a straight SATA power female-to-male cable? Why do so many companies sell 4-pin molex to multi-SATA power cables?! Like Bitfenix and NZXT. Are there 6-pin-to-male-molex cables included in the Corsair AX760 modular cable kit?

Those are Molex to PCI-E adapters in case your PSU doesn't have enough PCI-E connectors.

 

I don't know if these adapters are included, but they are almost always included with video cards.

Because molex used to be the only connector that peripherals would support. Sata power is relatively new (compared to molex), so you do not see things like straight sata to sata extensions too often.
