14 DAY TRIAL // German-Chinese power and cooling device manufacturer Xilence has just announced the new XQ Series Power Supplies with models ranging from 750W to 1000W, on its official website.
There's a total of three new models: a gold-certified 750 Watt unit and a platinum-certified 850 Watt that are available now. The 1 KW platinum version is expected to be launched at the beginning of next month.
The new PSUs (power supply units) have a very modern design that has clear functional utility, rather than aesthetics reasoning.
On the inside, the XQ series PSUs have much less cabling than most of the other players on the market. That really improves airflow and decreases specific conductor resistance.
The modular connector board is directly soldered to the main PCB. This is the main reason that all that cabling was removed and it also simplifies the servicing of the unit.
The first line of capacitors, next to the modular connector board, are all solid capacitors that are much more resilient and reliable than standard, electrolytic capacitors.
Having less internal cabling, the airflow inside an XQ PSU can actually be taken into consideration.
Usually, due to the fact that a high-end PSU has so much internal cabling that there is no actual way to direct the airflow, the PSU manufacturers use a big 120 mm or 140 mm fan that will blow air over the whole PCB with all the components and cabling on it.
If the main fan fails on a usual PSU, the deterioration of the PSU components will be rapid and surprising.
On the XQ Series, there are two different fans. They are much smaller, with a diameter of just 60 mm, but the manufacturer brags that they are powered by motors designed for 80 mm fans.
The PSU will keep complete silence until it reaches a load of about 20%. Beyond that, the fans will start spinning, but there are two temperature sensors, one for each fan. If one area of the PSU is cooler, the connected fan will spin slower or stop spinning altogether.
Because the PSU is completely silent at start, there is a power LED to tell the user that the unit is on, as there is no noise until it reaches a higher load.
The main difference between the models, besides the efficiency certifications, is that each of the four 12 volt lines are able to supply 16 amps for the 750W model, 18 amps for the 850W model and 22 amps for the 1 KW unit.
Official pricing stands at 189 EUR for the 850W model, and 179 EUR for the 750W one. That would be 243 USD and 230 USD, respectively, for the US buyers.
