It is well known that Rosewill is a company that started off as a subsidiary of Newegg, originally focused on marketing simple bits and hardware at very competitive prices. Rosewill grew vastly in a relatively short time and fledged into a stand-alone company with an impressive range of products. Today, Rosewill offers a myriad of products from simple cables and adapters to advanced computer hardware, home appliances and office products. The sheer number of products Rosewill markets today is makes ones mind boggle. Nevertheless, the company is strongly localized, with their products readily available only in the North American markets. Rosewill is making moves to enter other regions and some, but not all, of their products can also be found in Southeast Asia, Japan, China and Australia.

Rosewill's marketing policy is strongly based on the offering of low cost products, not differentiation. Despite their very large range of products, generally speaking, most of them are designed so as to compete in terms of value, with the company and the designers trying to outprice the competition, not outperform it. Rosewill will commonly minimize investing on features they deem unnecessary, such as aesthetic improvements or innovative elements, trying to deliver products of similar quality and performance as the competition at a lower price. Today we will be having a look at the best PSU series Rosewill currently offers, the Quark, the embodiment of Rosewill's business stratagy.

On paper, the specifications of the Quark PSUs are very impressive, with high current lines and 80Plus Platinum efficiency. As a matter of fact, Rosewill went through the trouble of getting official 80Plus certifications for every unit of the series, not just one or two models. All of the Quark PSUs also come with a five-year warranty. However, there are no fancy features such as lighting, USB interfaces and power meters. Rosewill supplied us with four out of the six units of the series, the 750, 850, 1000 and 1200 Watt models, so we are having a very thorough look at the series in this review.

Packaging and Bundle

Rosewill supplies the Quark series PSUs in typical, sturdy cardboard boxes. All of the boxes share the same artistic theme, a conceptual shape of a few quarks on a black background, with information and specifications printed on the sides and back of the box. Only the 750W version has a slightly smaller box, hinting that this unit has significant differences in comparison to the more powerful models.

The Quark series PSUs are not accompanied by the most generous bundle that we have ever seen, but it is better than Rosewill's usual frugal bundle. Inside the box we found a very basic manual, an AC power cable, a few short cable ties, four black thumbscrews and a nylon pouch with the modular cables stored inside it.

To our surprise, the modular cables of the Quark PSUs are made of simple, color coded wires bounded with black sleeving. These are the most basic cables available and are usually being used by the budget segment of the market, for small PSUs designed for the average home/office PC.

    The Rosewill Silent Night is among the finest power supplies ever manufactured.
    Of course, it was manufactured by SuperFlower, the only company I'd put on par with Seasonic in terms of quality. You are probably referring to some other line of Rosewill.
    Fanless and runs my 6-core i7, 970GTX, and five hard drives without the slightest voltage drop.

    Then not only are you missing out, you are also missing the point. Rosewill is not the one you should avoid, but rather, the OEM of the internals is the one to avoid. A lot of PSUs sold use one of several OEM models, and the ones used now are pretty good. Reply

    "Seasonic's infamous SS-1200XP3"

    Is there something wrong with the Seasonic? How is it infamous?

    Infamous is not an indicator of something bad. It just means that it's a noted product. That could be for it's stellar performance or simply what it's known for. Reply

    You're wrong.

    infamous: well known for some bad quality or deed.

    The author used the word incorrectly, but apparently a percentage of the readership won't know the difference so ... the downward spiral of the English language continues!

    It was known for being badass, baby. Reply

    Oh, there is absolutely nothing wrong with the Seasonic model. The original word was "influential", I did not really felt that it was suitable and I replaced it during my second pass. Apparently, I messed up while editing the text by either not deleting the word completely and the auto-correct function completing the new word as "infamous" or by just subconsciously getting influenced by the "in" prefix of the original word. Anyhow, of course the correct word is "famous".

    Thank you for your notice, it has been fixed.

    Unlike their 1050 model which could be "heard from rooms away." Now that one was infamous. Reply

    Who names a PSU 'Quark'?

    'Lepton' would make more sense; electrons have no quarks.

    I have the 1000 watt model, and it is a beautiful PSU, simple, powerful, and silent. The only issue is the cables are rediculously stiff, even in my full atx case, it took quite a bit of force to manipulate them down so they wouldnt butt against the case. No other model has ever had such stiff cables in my experience. Reply
