There are three cables that are not modularized, but run directly inside the PSU. The top one is, of course, the 24-pin ATX cable. The connector is backwards compatible to 20-pin and all the pin sockets are gold plated for maximum conductivity. The two lower connectors are for auxiliary CPU power. On the left is the familiar 4+4 connector that splits in two, allowing either the older 4-pin connection or the more recent 8-pin “EPS-type” that is showing up on an increasing number of enthusiast boards. The other 8-pin connector was somewhat of a mystery to me, so I checked out the manual.
I scanned this page to share with my readers, and a quick look around the web yielded little information about this connector. I know that Intel, in their QX6700 test instructions, recommends using an ATX 2.2 PSU with an 8-pin EPS-type +12-volt connector, and not using a PSU with a 4-pin to 8-pin adaptor, but that doesn't explain the different connector design. If you look carefully at the photo, two of the yellow wires have an orange stripe, which I found to be in the EPS 12V 2.91 spec. In this case, the +12V power needs to come from two separate rails, for two separate processors. This doesn't seem to be possible given the configuration of the sockets on the PSU, so I'm at a bit of a loss here. I suspect we may be seeing a socket for this connector on some enthusiast boards in the future. At any rate, these two connectors are NOT interchangeable. If the connector doesn't slide into the mobo socket easily, you're using the wrong one.
As I stated earlier, there are a lot of cables in the package, and not all of them can be used at the same time. Take for instance the VGA card connectors.
There are a whopping nine cables that can be used in various combinations to feed the latest power-hungry multi-GPU solutions available today, and even some that aren't on the market yet. The cables are clearly labeled as to which connector goes where and from which rail. The three adapters in the center can be used to take power from an 8-pin cable down to six pins, giving the user support for up to three high-end graphics cards. You know…
…the 8800's with twin 6-pin connectors like the one pictured here. (If I could afford a pair of cards like this and the Thermaltake 1000W to run them, I'd probably use the money to pay down my mortgage, but that's just me.) Similarly, the 1000W will support three cards with 8-pin +12V power connectors. These are quite rare now, but they're coming.
The main cables all have what I assume to be some kind of filter near the card-end. All cables are nicely sleeved with a black mesh material and then secured with black shrink-tubing.
