Modular Cables:

This is one of the more unique units I've seen as it has a lot of connected non-modular cables as well as a whole bunch of modular cables to boot.  The connected cables include the 20/24 Pin Motherboard Connector, 4/8 Pin CPU Power Connector, 3 SATA Connectors, 3 Standard Molex Connectors and two PCIe 6/8 pin connectors.  These are not modular - they are hardwired to the PSU.  The modular connectors include an additional 2 PCIe 6 pin connectors, 7 Standard Molex connectors, 9 more SATA Connectors, and 2 Floppy Connectors.  The diagram below shows all the cables and connections.  There are a bunch - 12 SATA, 10 HDD/ODD, 2 Floppy and 4 PCIe.

All of the cables are sleeved with a nice flexible material that helps maintain cable clutter while being co-operative enough to bend where you need it to go.  Below are a couple pictures of the different cable bundles.

Inside the PSU:

As we open this unit, please keep in mind that opening a Power Supply will completely void the warranty.  Not only that, but because of the large capacitors, you can suffer a serious electrical shock if you touch the wrong thing.  Please do not open your PSU to compare what the insides look like.  Instead, click on the images below for a closer look.

The heatpipes appear to cool the unit quite well as it stayed quite cool during heavy testing and prolonged use.  We managed to pull a maximum of 683W through this unit during some Call of Duty 4 in SLI and it got quite warm, but remained quiet and appeared to be solid as the system didn't suffer any instability.

On the next page we'll briefly cover our PSU Test methods before we jump into full-blown PSU testing.
