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.

    I was super excited for a Rosewill product with this kind of quality thats *fully modular*, right up until I saw the price point. A Corsair CX750M is about $85 and frequently goes on sale for less or includes $10-15 rebates. Granted it's only 80+ Bronze rated, but the practical differences between a Bronze and a Platinum unit are very small, if not totally meaningless for most people, and certainly isn't worth a $45+ price premium.

    Honestly, I think Rosewill missed the mark with these pushing for that Platinum rating.

    They're part of a line, and while the cheap high end is a somewhat limited market, they've got the lower end parts covered, and up until the top if they hit their pricing targets they'll be selling their platinums against other companies' golds and so on down the chain. Reply

    You need to compare these PSUs (pricewise) to other platinum power supplies. If that is out of your budget you can always buy a bronze rated Rosewill if so inclined. Reply

    You're comparing a budget model PSU to a non-budget model PSU. Do you also compare Chevy to Porsche? McDonald's dollar menu to Five Guys?

    You should instead be comparing this PSU to Corsair HXi and AXi if you want apples to apples.

    Yes Chevy has been compared to porche for a long time. Corvette and camero come to mind. Price per horse power has put the corvette ahead of more expensive porches. And at those costs, built quality in both are as good as porche but with far lower maintanen costs (and fewer trips to the shop).

    I think the original comment still stands. On paper these drives have some differences, but in real world application the cheaper psu operates at near or same performance as the premium psu.

    So one can brag about owning a porche, but next to a stingray their gonna be smoked and left realizing the only bonus to their more expensive hardware is image. As for me, I'll happily save money and make a porche driver frown.

    You're right. A stingray would be left smoking on the railing if it tried to stay with a Porsche on a twisty track. Reply

    Really? The ZR1 is only 1+ second slower than a 911 GT2. Reply

    On the Nurburgring that is. Reply

    ZR1 - $70k
    911 GT2 - $120k

    ZR1 (hell even the Z06) has a better 0-60 and 0-100, same times around test tracks, better insurance rating, better maintenance time lines (and a whole lot cheaper), and gets better gas milage.

    The ZR1 is faster, quicker, and can corner better than any Porsche at the same price point. It might take Americans a lot longer to figure out how to make a true sports car out of an aging muscle car, but the Corvette is there.

    Let me also point out the new style Corvettes (99 and newer) have won 6 LeMans in the past 12 years. That track has corners, and Porsche does compete int he same class. That's a pretty good track record, and one that hasn't been broken yet.
