• Support PCI Express

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!
