ASUS RS520-E8-RS8 Barebones Server Review

Power Consumption


We have upgraded our power testing equipment and now use a Yokogawa WT310 power meter for testing. The Yokogawa WT310 feeds its data through a USB cable to another machine where we can capture the test results.


To test total system power use, we used AIDA64 Stability test to load the CPU, and then recorded the results. We also now add in the power use for a server from off state to hitting the power button to turn it on and take it all the way to the desktop. This gives us data on power consumption during the boot up process.




The ASUS RS520-E8-RS8 server peaks out at just over 500 watts when put under full load, which is very good for a system like this. Of course, adding in a full load of hard drives will make these power use numbers higher. Idle power use is in the range of ~110 watts, which is what we expected for a system like this.




Booting up the ASUS RS520-E8-RS8 server peaks out at ~340 watts then quickly settles down to ~110 watts sitting on the desktop. System boot up times are in the range of servers that we have tested before.



Final Thoughts




This is our second barebones server kit we have had in the lab to test out and we can say this one has it all.


The ASUS RS520-E8-RS8 server barebones kit comes with everything you need to get your server up and running. Unlike others, this kit comes with rails and heat sinks, so you no longer have to go hunting for these items. This is a big plus to us; sometimes rail kits are only available at off brand stores and come with a high price. The RS520-E8-RS8 rail kit is simple to install into a rack, which is also a nice addition. We have racked up a fair amount of servers in our time and these kits are about as simple to set up as they come. Trying to line up a heavy 2U server into front loaded rail guides requires two people for the most part; the RS520-E8-RS8 is a top loader, which is much easier to snap into place. The server itself is lightweight and has a short depth, which makes it easy to move around and lift to rack heights.


The supplied passive CPU heat sinks are also of high quality and perform very well. These could be a challenge to source if not supplied with the kit as they fit the plastic air shroud tightly. The air shroud fits snuggly into the cooling area and provides a nice tight fit to channel air through the system.


The server itself is of high quality with ample expansion options. The case itself is well designed and built with solid construction that keeps the server nice and flat, it does not flex around when lifting. Many of the servers we have tested forced us to cram our fingers into tight areas to install things like RAM and CPUs. The RS520-E8-RS8 server has plenty of clearance inside for these tasks with only one location on the right hand side where clearance was tight.


Overall, setup was a breeze on the RS520-E8-RS8. The motherboard used in this server is the Z10PR-D16 server board, which offers good expandability and allows 16x DIMMs to be installed. We like this motherboard a great deal and reminds us of the Z10PE-D16 that is used in the TS700-E8-RS8 Workstation. Both these boards have excellent BIOS's that we have come to expect from ASUS products.


Another factor to consider about the RS520-E8-RS8 server is its low power use compared to some other servers we have tested, in this case as much as 50 watts in some cases. This adds up to lower running costs and less heat output. There is not much to dislike about the RS520-E8-RS8 server except we would like to have a DVD drive come standard with this kit. The RS520-E8-RS8 server is a good server kit that should get you up and running fast and provide a high power storage solution for your needs.
