Coolmax have been around for awhile, but have recently become more popular in the PSU market. Not too long ago, they released their CXI line of power supplies, which follow the new ATX 2.0 standard. Their higher models are even built for SLi use, in 500 and 600 wattages. Today, we are taking a look at their 400W version, so let’s see just how good it is!

Here is the official list of specs included with the PSU:

  • Support the latest Intel ATX 12V V2.0 spec.
  • Support PCI Express
  • Serial ATA ready
  • 3 Speed Fan Control Switch
  • 120mm fan design, long life, and fastest cooling time
  • High quality gold-coated fan guard
  • Cable-tube on main power cables for better cable routing and neatness
  • Over voltage protection, short circuit protection on all output levels
  • All DC output wires have 450mm length
  • MTBF > 100,000 hours @ 25°C
  • SLI Ready (Only available on 500W & 600W)

The supply comes ready with all of the connections you’ll need. It includes 6x basic 4-Pin Molex, a 24-Pin Mobo connector which can be altered to become a 20-Pin, 2x SATA, 1x 4-Pin P4 connector, 2x 4-Pin Floppy and 1x 6-Pin PCI-E. If you purchase the 500w or 600w version of this PSU, you will get 2x of the 6-Pin PCI-E connectors.

Above is the table overview of all the available wattages in the CXI line. The one we are reviewing today is outlined in black, and as we can see, it’s sufficient for most systems out there today. If you have a lot more going on in your computer, including an SLi setup, you will want beefier wattage just to play it safe.

I tried opening the PSU to get pictures of the inside, however there seemed to be something in the way. I didn’t want to risk breaking anything. Therefore, no pictures of the insides, sadly. At any rate, let’s jump right into testing!
