According to the graph on the side of the PSU, the Tagan stays at a nominal 500rpm up to a 50% load, and then rises steadily up to a maximum of around 1800rpm. Even at maximum load the claimed noise output is a mere 28dB, where as at 500rpm it was an excellent 21dB.
The PSU is auto switching from 95 to 250V VAC, meaning it will happily take your countries mains power source regardless where you are from. The on/off switch is protected from wet hands by a plastic cover which you can remove if you prefer.
Opening up your PSU will not only void the PSU, but should never be done unless you are a professional electrician. Even when not plugged in, and seemingly discharged for a long period of time, a PSU can still hold enough charge to give you a very unpleasant shock if you touch the wrong part. Don’t try this at home folks :).
Inside the Tagan is a masterpiece of precision engineering. Seemingly decent power supplies like the Hiper range look great from the outside but open them up and they look like they were made from scrap metal, and thus perform as such. Not so the Tagan, with excellently placed heat sinks and intelligent airflow arrangements. So far then, the Tagan gets full marks for an excellent specification and far better than expected build quality, but the truth will be in the testing!
