I only ran into one slight problem during installation. The SATA power connectors are too close together to power two drives positioned horizontally side by side with one lead. Looks like the connectors are spaced for stacking drives vertically, the "standard" way. But, this is easy to get around of course, simply run another SATA power lead to power the second drive.

The ET-850 installed and everything hooked up. I used the included zip-ties to bundle up any wires that I'm not using, which you can see sitting on the floor of the case.

The power indicator light glows orange when there is power to the PSU and the system is turned off.

The light turns green when the system is powered on.

The readings shown are the averages of the high and low readings on the rails over a week of use through a variety of applications and games. Since most power supplies correct any fluctuation in the current to the rails before our multimeters would even notice, and because we lack the proper equipment, we're unable to monitor every output in realtime simultaneously, so these are very rough ideas.


This unit provides a lot of power and a lot of power connections, more than the average user needs. Not everyone has a quad-core CPU and a graphics card configuration requiring more than two or even a single PCI-E connection, but for those that do, the ET-850 certainly won't let you down. With four PCI-E leads and SLI Ready certification, it's ready to push that new quad-core + 8800GTX SLI setup that you've been dreaming of. It would be a great choice for that new system, but can be a little heavy on the wallet compared to some alternatives with an average retail price of $230 USD. As with everything, you get what you pay for.


Plenty of wattage/amperage.
Plenty of power connectors.
Ready for the road ahead.
Quiet operation.


SATA power connectors are spaced a little short.

We would like to award the Etasis ET-850 our OCIA.Net seal of approval.
