Final words and conclusion

What we did like:

Let us cut straight to the chase, the HX620W is one hell of a powerful supply. It is immensely strong and stable. No matter how heavily loaded the power lines would barely quiver. The design of the HX620W is excellent, as the unit is elegant and eye-catching and is a refreshing change from the gaudy and ugly power supplies we get into our testing labs. We also enjoyed the silence of the HX620W under normal operation, which is something every user should be thankful for. Last but certainly not least, Corsair offer a 5 year warranty for this unit which should give a prospective customer a great feeling of reassurance.

What we did not like:

The only possible downsides to shortlisting the HX620W would be the noise from the fan under full load and the asking price. If someone was to connect this unit to an extremely high end SLI or Crossfire gaming system with a plethora of hard drives and other hardware connected, the noise generated by the HX620W could very well become tiresome. However, for reference, a system with a highly overclocked Conroe processor, 5 hard drives and an ATi X850 Pro video card was not enough to make the fan of the HX620W speed up at all. Lastly, the price of the HX620W makes it one of the most expensive power supply units currently available, and we feel all but the most serious enthusiasts may find this product out of their price range (160 euros). That said, quality is never cheap.

Who we would recommend it to:

The Corsair HX620W power supply unit is simply state-of-the-art. It is extremely powerful, stable and entirely silent while installed in a typical high end enthusiast system. It is also built with the finest material and comes with a reassuring and exceptional 5 year warranty. However, the price of this power supply unit is quite high, therefore realistically it will be marketed to the higher end enthusiast with a larger income, in this case it really is one of the best units money can buy. The HX620W could also be a great choice for small to medium sized servers, and in this environment the price would make it somewhat of a bargain. A wonderful showing from Corsair.

Taking all of the above into consideration, we strongly believe that the Corsair HX620W is worthy of our Editor’s Choice award, if the noise levels had been slightly lower when powering the most extreme gaming systems then (even with the hefty price tag) it would have won our coveted Heavenly Hardware Gold Award.

What do these awards mean?

The Corsair HX620W retails for ~160€ in EU at the time of this review.
