From the bottom of Jonny's review:
UPDATE (1/3/11, 17:30):
Soon after this review going live, I was contacted by someone from Corsair. Apparently the CX-430 product page is chock full of typographical errors because a good amount of the product description was copied and pasted from the CX-400 product page. One such error is the statement that this power supply is 80 Plus certified. Corsair tells me that this unit is NOT 80 Plus certified. Another error on the website is that the unit has a ball-bearing fan. Of course, in our autopsy we found that the CX-430 actually has a sleeve bearing fan. Today, these errors have been fixed.
