Circuit Design

It is not easy to take this PSU part because some of its screws are hidden under the label.

It wouldn’t be much of a problem if the label were not made from an aluminum plate. It is hard to tear it off the PSU and even harder to make the PSU look nice after such disassembly. The typical paper sticker Warranty Void If Removed looks like a child’s toy in comparison.

There is nothing new inside. The PSU only differs from the above-discussed Xigmatek with the color of its heatsinks (and this color has no effect on cooling because the PSU is equipped with a fan). It is the same platform developed and manufactured by Channel Well: two 750W power supplies in a single housing.

There is no point in describing this PSU in detail – you can just refer to the description of the Xigmatek NRP-HC1501 above.

Cables and Connectors

The PSUs differ a little in connectors. The Thermaltake has the following:

  • Mainboard with a 20+4-pin connector (50cm long)
  • CPU cable with an 8-pin connector (53cm)
  • CPU cable with a 4+4-pin connector (53cm)
  • One cable with one 8-pin and one 6-pin graphics card connector (54+15cm)
  • Three 8-pin connectors for graphics card cables
  • Three 6-pin connectors for graphics card cables
  • Four 6-pin connectors for peripheral power cables

Included with the PSU are:

  • Three cables with one 8-pin graphics card connector (50cm)
  • Three 8-to-6-pin adapters for graphics cards (15cm)
  • Three cables with one 6-pin graphics card connector (50cm)
  • Two cables with four Molex and one floppy-drive plug on each (50+15+15+15+15cm)
  • Two cables with four SATA power plugs on each (50+15+15+15cm)

So, the difference is that the Xigmatek offers universal 6+2-pin connectors for graphics cards whereas the Thermaltake offers 8-pin connectors and adapters for 6-pin connectors. Xigmatek’s solution is handier and more reliable.

The cables are designed in the same way in both PSUs, up to the stickers that indicate what end of a power cable goes into the PSU and what +12V line the connector of a particular color belongs to.


The specs are exactly the same as those of Xigmatek’s PSU. The PSU is rated for a total output power of 1500 watts and consists of two sub-PSUs, each with a peak load of 750W. It offers two independent +12V rails, each of which is additionally separated into two “virtual” output lines.
