Noise

The supplied 120mm fan is nicely quiet and doesn't intrude on your everyday PC use in anyway. However, during the testing the PSU would emit a strange whining noise when 3D applications were run. The noise is a bit irritating and is almost audible above case fans. Bottom line, those with silent PCs will be very annoyed by this, those who wear headphones all the time or have several high powered fans in their case will barely notice it.

Cost

You can find the Olympia 650w for around £90. which is about on par with the 600-700w offerings from other brands.
