Unlike 600 watt power supplies that are designed with high output for graphics cards in mind this power supply is designed with quality smooth power and high performance in mind.

It has lots of cooling and the case itself is designed to dissipate heat better with its aluminum material. There is more than one power rail which allows correct power to be directed at processors and motherboard. For a 600 watt power supply it does more than a good job at powering a workhorse machine that is used heavily, but not for gaming or overclocking. That is not its intention.

XG Vortex 600 watt power supply

XG Vortex 600 watt power supply

An interesting claims made by an online retailer of this 600 watt power supply is that of “silent fans” There are limited ways to make a power supply silent. All fans make a noise, but big ones move more air at lower RPMs reducing the noise. Silent is obtained when fans are off, or the power supply has none. There are better and worse fans, so which ones you have make a difference to the overall quietness of the system.

In all fairness I’m not knocking the power supply, but just some marketing tactics you need to be aware of when buying.

This 600 watt power supply gives some of the highest power outputs on the 12V in its range. It gives up to 37Amps which is enough power for most bits and pieces in your system. Its fans are quiet, but certainly not silent. You can’t really go wrong here, the power supply appears good and its price is not bad. The only worth considering is maybe if you would rather go for a more well known brand, which gives you a little bit more assurance of things going well in the long term.

Aspire Dark Side 600 watt power supply

Aspire Dark Side 600 watt power supply

The Aspire Dark Side 600 watt power supply has a certain cool factor to it. Besides doing all the usual stuff for a power supply in this range it also manages to give a good impression with its lights, and also with its good flow of cool air.

With 3 fans it has enough to keep cool air flowing well through the power supply and getting that fresh, cool air inside to keep things at the temperatures they need to be at.

The blue lights and UV sensitive parts inside will appeal to those who have cases with clear sides and like their cases to be showy. It is obviously aimed at the heavy user, which is why they have included so many fans in their setup. Gaming produces some of the highest power consumption and those fans keep things cool when the power supply is working under full load.
