FSP Aurum Pro 850W Power Supply Review

Installation & Testing
Getting the Aurum Pro installed is very easy.  We will be installing it in our Cooler Master Cosmos II case, so we have quite a lot of room to work with.  Because the power supply is partly modular you only use the cables that you need so there will be less clutter inside of your case.  With the Cosmos II there was more than enough room inside the case to route the cables behind the motherboard tray.  Also I really liked how strong and thick the modular cables were.  You are definitely not going to rip or cut these cables on any part of your case.  Below you can see the power supply installed and our wiring job.

One thing that I noticed when I installed the power supply was that the actual power cable was unlike the “standard” power supply connector we are all used to seeing.  At first I just thought it was thicker and more heavy duty, but the connectors were a little different.  This means it is proprietary, and if you don’t know by now I am not a fan of proprietary anything!  So if for some reason this cable breaks I have to try and find one that is just like it rather than use one of the 20 or so normal power supply connectors I have here.  Check out the photos below to see the difference in the cables.

Now for testing, our test system is comprised of the following items:

Processor: Intel Core i7-920
Motherboard: ASUS P9X79 Pro
Video Card: Sapphire Radeon HD6950
Memory: 16GB G.Skill RipjawsZ
Power Supply: FSP Aurum Pro 850W
Storage: 750GB SATA II Drive
Cooling: Noctua NH-L12
Case: Cooler Master Cosmos II with 3 fans

We will be running OCCT for 1 hour to stress test the power supply.  Initial spot checks on the 3.3V, 5V and 12V rails are 3.328V, 5.160V and 12.192V respectively.  Below you will find the results of our tests.




The 3.3V rail had the most ‘ripple’ as you can see from the graph above.  It also had the most deviation at 1.29%.  The 5V rail had a deviation of 0.87% and the 12V rail had a deviation of 0.75%.  We like to see a deviation of 5% or less so these results are very good.
