External Features
The most striking thing about the RPP850 is the paint job. It has a fine mirror finish that reflects very well. This isn’t necessarily a very important feature of the power supply, but it will serve case mod enthusiasts well, considering it will readily reflect lights for a nice effect. Beyond the finish, you can clearly see the large 135mm fan mentioned above. Another curious feature of the RPP850 is the lack of a power switch on the back of the unit. We usually like to see a switch on the back of a power supply for safety reasons, as we are quite often messing around inside the computer while installing and uninstalling things. Certainly, having a power switch disengaged at least gives you the piece of mind that you won’t be electrocuted. On the RPP850, there is an LED that we assume represents whether or not it is safe to make changes to your computer. When the LED is green, the PSU is functional and delivering full power to the system. When the LED is orange, we assume that you can make some changes. However, removing the power cable inevitably is safer still, since it turns off the power completely, and really is not that much more difficult than flipping the switch. However, we could definitely see this being an issue for some people that value the ability to quickly switch their power supply on and off.


The final external feature of this power supply is the specification sticker. What is surprising about this sticker is that it is far simpler than what you would expect from a power supply with 6 +12V rails. Overall this label is no more complicated than the one we described in our "What’s a PSU?" article.
