Welcome, today I'm taking a look at a new power supply from Etasis, the ET-850. The ET-850 is an 850 watt power supply complying with the latest ATX12V and EPS12V standards(v2.91), and it is of course downwards compatible. The ET-850 is certified to be SLI Ready by Nvidia, and even features four PCI-Express power leads for graphics cards. It is rated for over 80% efficiency with four independent +12V outputs, and has eight Serial ATA power connectors. With plenty of power and plenty of connections, it sounds like it's ready to take on anything available on the shelf from quad-core CPUs to SLI graphics cards with as many Serial ATA drives as you can fit in most cases.

Etasis may be a name that you've never heard of, but Etasis is well known for building high-end power supplies for Silverstone, Thermaltake, and Cooler Master. Their goal is to be the choice supplier for OEMs / ODMs (Original Equipment Manufacturer, Original Design Manufacturer). Just like companies that you never knew existed actually built your Dell/NEC/Compaq/Acer/etc notebook.

Moving along..



The ET-850 arrives in flashy retail packaging with a convenient handle on top to carry it by.



On the back side of the box we get a preview of the PSU and the four dedicated PCI-Express power connectors. The features of the unit are printed in six different languages including English.



Moving in closer to the back side of the box, we can see that the ET-850 utilizes X-Tech technology to help provide the cleanest power for the best stability. The ET-850 also features IFM (Intelligent Fan Management) for the lowest noise level possible.



Turning to the side of the box we get a look at the power specifications:

+5v: 30A
+3.3v: 28A
+12v1: 18A
+12v2: 18A
+12v3: 18A
+12v4: 18A
-12V: 0.5A
+5VSB: 3A

These specifications certainly look up to snuff, plenty of amperage all around.



Opening the box, the first thing we find is the user manual inset in a piece of cardboard covering the rest of the contents.



Removing the cardboard reveals the ET-850, it's bundle of power connectors and a box for accessories.



In the box, which by the way also has very nice graphics, we find a large gauge AC power cord, mounting screws and some zip-ties to help tidy up the installation.



Our first look at the ET-850 out of the box, still in protective plastic wrapping.
