Use and Stress Testing
I used OCCT Perestroika in conjunction with Everest for benchmarking and monitoring on Windows 7 64-bit after installing into my standard testing rig with an ASUS M3A32-MVP motherboard, Athlon X2 6000+, 8 GB of DDR2 RAM, three SATA hard drives, a Kingston V-Series 128 GB SDD, a Killer 2100 Gaming NIC, and a Sapphire Radeon HD 6850 inside a Cooler Master Cosmos S case. It’s a little older rig, but it still packs a wallop.
Spot checks put the 3.3V, 5V, and 12V rails at 3.34V, 5.09V, 12.38V idle and 3.26V, 5.02V, 12.22V under load. Stability!
As I’ve not reviewed anything with this low of wattage in quite some time, there are no comparison graphs. Check out some of our other power supply reviews for comparisons.
The 3.3V rail had a 0.91% ripple and was well within our desired range of plus or minus 5% of the specified voltage. It undervolted during, but not by much.
The 5V rail had a 0.98% ripple and was also well within our desired range. It was overvolting, but not by an appreciable amount.
The 12V rail had a 1.06% ripple and was within the desired range. I would have liked to see it a little closer to specification, but it was acceptably overvolting.
As for noise, well. It’s fanless! Zero noise!
