Yep, but they compared them as if they were different. So are they both made at the same location?
I read an article that covered this. Both brands, and the companies (before they merged) have multiple product lines. These products are made using different designs, possibly in different factories. After the companies merged, it is reasonable to expect that the product lines will also merge. However, you can still expect that their high end and low end models will remain completely different designs, and may be made in different factories.
For example, HardOCP dissected a couple of OCZ power supplies during reviews and found that one was a very high quality design that they had not seen before, and another one was simply a generic design outsourced from a company that makes power supplies for a whole bunch of companies including OEM customers.
So it depends on what model you get... Some are going to be generic PSUs with OCZ or PCP&C labels, some will be more custom high end designs. In both cases, it is unlikely that a factory staffed with OCZ or PCP&C employees actually manufacturered them since they order their PSUs from third party manufacturers. It doesn't necessarily mean they're cheap or crappy, it just means that you might buy 5 PSUs with 5 different brand names, and then if you open them up you might find that they're nearly identical inside.
That's why if you are really serious about picking your computer parts, you need to read PSU reviews that take them apart and look at internal build quality. Whether or not you like hardOCP's testing methodology, they disassemble every PSU and comment on build quality including identifying the actual PSU manufacturer and comparing the actual design to other PSU brands that use the same design. You'd be suprised at what they find... They have taken apart 800 and 1000w PSUs and found them to be absolutely identical, down to the heatsinks and capacitors. The brand name company can special order these generic designs with custom wiring or better components, but there are actually only a handful of manufacturers and designs so it's possible to narrow down which brand is selling the "good" ones at a lower price if you do a lot of research.
