This is the 420 W model from Hiper and is also the most topical as 420 W has become a kind of standard wattage for modern, power demanding computers. The power is rather good divided between the different voltages, though I would like to see a little more on +12V and +3.3V. However, these figures are not that low that it becomes a problem. Just like its little brother, this PSU have gold-plated connectors. Eight large and two small connectors are enough for most things and the cable length is just enough for a midi tower, but if you have a full tower you may encounter problems.

This power supply is gray just like the weaker model, but there are lots of other differences. To start with is that the ATX cord is covered with a wire loom to get the cables out of the way. This is a very nice solution that can be found on several PSU's. Further more the fans are transparent, which is quite pointless as there is no kind of lighting anyway inside the power supply. You could of course mount lights yourself if desired.
When it comes to cooling you can find an 80-mm fan on the back and a 92-mm fan at the bottom. Both of them are temperature controlled, but can be adjusted manually through a switch on the back. This power supply is actually more silent than the 350 W model, as the fans do not need to run as fast to achieve the same airflow and cooling.
