Sirtec may not be one of the known big players of the PSU industry, but in fact they are a huge OEM producer of power supplies, for example for Thermaltake and Chieftec. We test Sirtec's 410W unit which offers a beautiful chrome finish and a low-noise fan at a very competitive price.
Thermaltake has put together a nice package consisting of a PSU with modular cables, a 5.25" drive bay real-time Watts Viewer and an additional 120mm case fan.
Today we have a very special PSU on the test bench - it is completely passive. Fortron trusts their design so much that they say a backup fan is not needed.
I was surprised to see the Fortron Sparkle ZEN power our demanding test platform without any load problems. While the electrical noises were definitely annoying, they are only noticable on higher power systems.
Silent and powerful? Is the included CPU HSF worth it?
The 5V and 3.3V lines are exceptionally stable. The 12V line tends to fluctuate a bit, but stayed above 12V at all times. All lines are well within the limits set by the ATX Specification.
