Testing the ZM1000-HP Modular PSU

Modular Cables:

Identical to the ZM850-HP this unit 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 867W through this unit during some Futuremark Vantage in 3-Way SLI and the hottest component we measured reached 52C, but remained quiet and appeared to be solid as the system didn't suffer any instability.

 

Test Setup & Info:

In the past, we've prided ourselves on real-world testing.  For graphics cards, CPUs and memory, what matters is what takes place in real applications and games.  We also held that philosophy for PSU testing, but after a while, we realized that there is more to a PSU that being able to run a machine stable over a few weeks or months.  In reality, if there is a lot of ripple, this can damage sensitive traces on your $700 graphics card or $1300 CPU.  A multi-meter alone is not good enough to check PSU voltage stability.  It's for this reason that we've updated our PSU testbed, and will continue to improve the detail and quality of our PSU reviews.  That being said, we will still be testing the PSU in a system and will be including stress tests from real components in the real world.

We recently purchased a Tektronics TDS2002 60MHz Dual Channel scope and it has already become invaluable around the shop here at BCCHardware headquarters.  I've used it to troubleshoot everything from PSU's to Radars, and we are using it today to check the stability of the Zalman 1000W PSU on the next page.
