FSP AURUM CM 650W Power Supply Review

The FSP Aurum S was good but the Aurum CM looks even better, especially with its modular nature. How does the Aurum CM hold out in my torture tests?

Unlike the Aurum S, the Aurum CM is an 80Plus Gold Semi-Modular PSU with quad-rail design.

Here’s the list of cables found on the Aurum CM 650w, notice how each cable is configured differently? All you have to do is choose those that suits your cable management.

This is where the cables connect. 4 for components and one for the PCI-E power connector. My only complaint is that it looks awkward when running multiple graphic cards as one PCI-E cable would be flat type with rubber sleeve while the other one is non-flat mesh sleeve.

Test Methodology / Report

goldfries.com does not have industrial grade power supply testing tools, therefore the approach for the PSU test is from a consumer angle. This means the PSU will be pushed to operational limit based on components that are available in the market. The key components used for power draw are the CPU (choice of processor), the GPU (graphic card setup) and other components like fans and drives.

The stress test is performed by stressing the 12V rails with 80% to 90% load, and run no less than 8 hours which is a lot more stress than what the average consumer would place on a power supply over the course of months or even years.

The FSP Aurum CM 650W delivers 600 Watts over the 12V rails so the target power draw should be around 540 Watts. The FSP Aurum CM is rated to be over 90% efficient so assuming the claim is true, the wall readings based on the target watt of 540 should be at least 600. The processing load was generated by running folding@home and Furmark Burn-in test.

The test system comprises of an AMD FX-8350 processor and 2x Gigabyte Windforce R9 280X units and 4 units of high RPM fan.

During the load test, the wall reading reached 650W – 50 watts more than what I intended and that’s approximately 97% of the rated power delivery. The test went on to more than 8 hours with no hiccups.

The 12V readings were astonishing, maintaining a stable 12.10V and hovers between 11.85V and 11.90V when on load. Readings were taken directly from the PSU via Digital MultiMeter.

The FSP Aurum CM 650 performed admirably – being stable, cool and quiet all the way.

The Verdict
