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 and a PCIe 6 pin connector.  These are not modular - they are hardwired to the PSU.  The modular connectors include an additional PCIe 6/8 pin connectors, 9 Standard Molex connectors and 6 more SATA Connectors.  You'll notice that I never mentioned Floppy drive cables.  That's because there are none.  FDD power is provided by using an adapter cable.  There are two floppy connectors on this "Y" cable, and this can be an issue is you still use a floppy drive as well as a 5.25" fan controller that also requires an FDD connector.  They may be two far apart to reach.

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 is a diagram of the cables included with the ZM750-HP.

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.

Cooling System

 

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 583W through this unit during some UT3 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.
