Introduction

There are only a few elite power supplies certified to run dual 8800GTXs and quad SLI and this juggernaut is one of them. The capability to run the power-gobbling 8800s in SLI says something about this PSU (Power Supply Unit). Very few power supplies can run a single 8800gtx, let alone two in SLI configuration. Featuring all of the latest standards and connectors, the ET 850 may be one of the best power supplies on the market.

What about Etasis? I bet you've never heard of Etasis Electronics. Neither have I, for that matter.  After doing some research, I found that Etasis has been making high-end power supplies since 1996. However, they only recently stepped into the gaming and enthusiast market. What is more surprising, is that Etasis designs and manufactures power supplies for other more publicized companies such as Silverstone and Thermaltake.

Closer Look

Quite frankly, I was very skeptical upon receiving this unit. I actually had the notion that it would explode, dismissing it as junk. But as soon as I picked up the box and got a good look, my apprehensions were blown away. Just picking the thing up made me tremble...literally.  The thing weighs a ton!

 

 

As you can see, the box is absolutely beautiful! Compact and stellar graphics, combined with an absolutely awesome box design! I cannot even begin to stress how effective Etasis' marketing has been on the box alone. As you can see, the top folds out revealing a cover board and the manual. The manual, though it is nothing spectacular (just the usual multi-language black and white with the specifications), it does go into thorough detail about the features and specifications of the unit.

After being dazzled by the box alone, I wondered what I would find under the cover.

 

Inside, we have the usual power cable, four screws and, of course, the manual. Also included are a few zip ties - a nice touch. But look! The included power cable is extraordinarily thick, almost twice the size of a standard cable! I guess you can attribute that to the fact that it eats 14 amps (US) of electricity at full load!

Now onto the main dish. 

Finally, the beast is revealed!

 

 

The first thing that comes to mind, is the lack of color. No, it isn’t bare metal, but a darker painted grey. As you can see, it includes a thermally controlled 80mm fan which takes in air from the case and expels outward. On one side is a large sticker with the power specifications, while the other has an engraved Etasis logo. The top and bottom are both blank and lastly, the PSU looks rather cramped inside. If you look into the back, the components inside are streamlined with next to no room, which explains the weight. And of course, you can see the power connector and main switch. There is also a multi-colored LED, which isn't exactly necessary.

What about the size of the Etasis compared to other power supply units?





The Etasis is on the far left, an Apevia Iceberg 680w next, followed by an Ultra X-Connect 500w and a generic 400w on the far right. The Etasis is quite long compared to the others, so make sure you have room for this sucker! Although, a PSU of this magnitude is normally about this large (The PCP&C 750w PSU is also 18cm long) It will still be pretty long for many cases.


PSU Measurements
Generic 400w 14cm
Ultra X-Connect 500w 15.6cm
Apevia Iceberg 680w Green 16.75cm
Etasis 850w 18cm
PCP&C 750w 18cm

The Etasis also has some very thick cables coming from the casing, so make sure you add another 4-5cm to the above measurement so that it won't run into various parts, particularly optical drives.

Cables are next!


The cables.

I have separated the cables according to type. The motherboard connector is a solid 24 pin connector, which will cause problems for 20pin users - make sure you have an adapter on hand! There are two P4 connectors, one a four pin and the other being the newer 8 pin. Both of these connectors have been sleeved with a black mesh that have little slippage and are very flexible. The same can be said for the four blue sleeved PCI-E connectors. There are 8 Molex, 8 SATA, and one floppy connector, all of which have been twisted and cable-tied to make everything tidier.

And finally, the back LEDs are shown below.


 

I turned on the power supply with nothing connected, and found the left image is 'off' while the right image is 'on'. I find it kind of silly that they included a useless LED but not a detachable 24pin connector. I guess they just want us to buy adapters.

Now that you know the product, let's install the baby!

Installation

Installation Setup

Installing the PSU is relatively simple, just slide it into your PSU bay, screw it in with the included screws, and plug everything in. Easy!



However, since this PSU is abnormally long, I ran into some clearance issues.

 

The PSU barely fits and if it were another 2cm longer, it wouldn't have fit without having to move something. Measure before you buy!

I proceeded to plug everything in. Since Etasis were too lazy to make a detachable 24 pin connector, I had to go out and buy an ugly converter.




Yuck! Etasis - it isn't that hard to spend an extra couple of cents to include a detachable connector. Other than that, installation was a breeze. All the cables are flexible and can make a 180 degree turn in a snap.

Finally, on to testing!

Testing

Testing Setup Testing Methods

I will test both Idle and Load voltages, first using software (Asus PC Probe) and then a digital multimeter to confirm the validity of the tests. Load will be tested by encoding and gaming at the same time. Keep in mind that even though this system is outdated, Prescotts (Pentium 4) have been known to consume more power than even the newest CPUs!  I will also be using an Apevia Iceberg 680w as reference.

Note: Even though there are multiple 12v rails, in my testing, there is no significant difference between the different rails at different loads. These charts will show the 12v rail marked "1" in the specifications.

WOW! These have got to be the most stable rails I have ever tested. The voltages are absolutely rock solid and do not fluctuate at all! This easily puts all of my previous power supplies to shame.

Noise, Cooling, and Stablity

When idle, the fan is dead silent, but admittedly, it is not moving much air either. At load, the fan speed picks up, but noise levels remain undetectable. Overall, it is safe to say that this PSU is dead silent and the automatic fan control is a definite plus!

For stability, I ran my entire computer at full load for 24 hours, and of course, the rails remained the same the entire time. Rock-solid stuff.

Conclusion

This PSU is arguably one of the best on the market today! The rails are absolutely rock solid and the entire PSU screams "Monster." I have no doubt that this juggernaut will run everything that can be thrown at it and things to come years down the road. The unit is dead silent and will run everything day and night. I no longer have a doubt in my mind of it running dual 8800s. This is a definite step in the right direction for Etasis!

On the negative side, it is a shade longer than the average power supply, so make sure you have room before buying it. Also, what really bugged me was the 24 pin motherboard connector, as it made it impossible to use a 20pin motherboard without the use of an ugly, bulky, adapter. I mean, come on Etasis - you could've left out the useless LED light and included a detachable connector to save us all a lot of headaches! That and the power supply isn't very stylish at all, especially for a so-called "gaming power supply."

The best power supply I have used to date. A definite 9.5 out of 10!
