Nach den zahlreichen Einzeltests im Netzteilbereich steht nun wieder ein umfangreicher Roundup der höheren Leistungsklasse an. Dieser ermöglicht eine bessere Vergleichbarkeit innerhalb diesen Bereiches. Wie ihr feststellen werdet, haben wir dabei einen bunten Mix an Produkten berücksichtigt, von ganz billig bis sehr teuer, mit Kabelmanagement und ohne. Die Eigenschaften der Geräte gehen teilweise weit auseinander und so können wir sehen, was man aktuell für sein Geld bekommt.
Through daily experience with common household equipment, many people should have noticed the terms AC and DC voltage and / or current; for example on a car battery which outputs 12V DC voltage or a household lighting lamp which needs 230V AC voltage. Yet only very few people can actually realize even that there are differences between AC and DC current, let alone understand the differences themselves. The purpose of this article is to explain the main characteristics and highlight the differences of AC and DC current, in terms understandable by people with very low or without technical expertise, along with providing some encyclopedic knowledge on the subject.
The brand bequiet! belongs to the German distributor Listan. This company has released several power supplies with the 80 Plus Gold certification, under the Straight Power E9 series. Five of them (400 W, 450 W, 500 W, 600 W, and 700 W) don't have a modular cabling system, while three of them do (480 W, 580 W, and 680 W). These models carry the letters "CM" for "Cable Management." Let's see if the 680 W model is a good option.
Die Kollegen von Hardwareoverclock.com haben ein neues Netzteil unter die Lupe genommen, das Cougar CM Power mit 700 Watt. Als Testsystem kam ein Core i7 mit einer GTX295 zum Einsatz. Wie sich das Netzteil geschlagen hat, könnt ihr im Bericht lesen.
The ST85F-G Evolution shares the same feature summary as the rest of the Evolution series. It has full of protection features including over temperature protection, but the unit is not rated for 100% continuous output at 50C. It is instead rated for 100% continuous output at 40C. The power supply is fully modular and fully sleeved. The full modular design also allows for the use of SilverStone's PP05 short cable kit.
Antares Pro comes in with the cheapest price of $168.99. Alternatively you can find the unit for $169.99 at Directron. Hardcore Newegg fans will find the unit a tad more expensive, costing $195.82 after shipping. At about $170, the ST85F-G Evolution is one of the cheapest 80Plus Gold rated 850W models available. SilverStone backs the unit by a three year warranty.
Today we take a look at another power supply from Corsair and we have the GS800 (V2) “Gaming Series” power supply in for testing. The GS800 boasts 80 Plus Bronze Certification, a bucket load of connectors, a 3 year warranty and more uniquely customisable LEDs and plastic strips (though the strips are sold separately). The GS800 is in this regard one of the most unique PSUs on the market in that it allows you to customise its colour scheme. Though by default it comes with a blue LED and blue strip to match the blue sticker. The Corsair GS800 uses blue, white and red LEDs which you can see below. These are switched between by using the LED switch on the rear of the power supply, accessible from outside the case.
Other than that there isn’t that much else to discuss because this is pretty much an 80 Plus Bronze non-modular PSU with some extra bells and whistles. Let’s proceed with the testing and see how good the GS800 (V2) from Corsair performs.
Both Be Quiet! Pure Power L8 power supplies made an excellent impression. Their efficiency, voltages, ripple, noise levels and price are exactly what you want them to be.
Aujourd'hui, nous testons la toute dernière alimentation de Cooler Master, la V, que nous avons reçue dans une version 700 watts. Une alimentation plutôt haut de gamme, qui s'offre une certification Gold, des câbles intégralement modulaires et un ventilateur de 135 mm silencieux. A découvrir sans plus attendre dans nos colonnes.
Scythe, a Japanese manufacturer known for its high-end CPU coolers, has also power supplies. Their latest power supply series is called Kamariki 4 and has 450 W, 550 W, 650 W and 750 W models and we are going to review the 550 W version, also known as KMRK4-550A. Let's see if it will live up to our expectations.
A lot of companies are in the PSU game, which is why it’s important to make sure the one you’re buying is a good one. Or at least, one that won’t damage your system. Because that can happen with a cheap unit and while here at XSR we might not have all the fancy testing facilities of the bigger boys, we can make sure that yours won’t overload your components at the first opportunity.
