Rosewill expands into audio with a pair of earbuds

Earbuds do not seem as popular as gigantic RGB sporting over the ear headsets, but there are still a few who prefer a more subtle approach to mobile audio.  The Rosewill EX-500 and 700 look similar but hide some differences inside.  The EX-500 uses a ceramic driver and a 10 mm dynamic driver while the EX-700 has a balanced armature driver and an 8mm dynamic driver.  That means there is a difference in impedance, 33 Ohm and 26 Ohm respectively though both retain a range of 20-40 kHz.  TechPowerUp tried both of these $40 earbuds out, read on to see what differences they found in the audio.

"The recently launched Rosewill EX-500 and EX-700 aim to take on the usual brands that dominate the price range by offering high-quality craftsmanship coupled with a nice accessories pack and - of course - better sound. We listen closely to see whether they can hold up on these promises."

Rosewill's Cullinan chassis, a diamond in the rough?

Subject: Cases and Cooling | September 19, 2016 - 01:49 PM |
Tagged: rosewill, cullinan, XL-ATX, MicroATX

The press photos at the start of TechPowerUp's review do not do the Rosewill Cullinan justice, that obnoxiously bright glow actually looks nice behind the tinted glass panels which the case features.  As you can see from the picture below the case does allow light through it but the reflective side and front panels are the obvious highlight of the case.  It will accommodate any motherboard from MicroATX to XL-ATX, at 8.54x19.57x18.78 you should be able to fit in the plus sized coolers from the review just below this post.  You might find that needing to remove all of the the thumbscrews to get the side panel open a bit cumbersome but when assembled it does look quite fancy.  Drop by TechPowerUp for the full story.

"The Rosewill Cullinan utilizes glass panels on three sides of the chassis. It looks sleek and clean and comes with four LED-equipped fans, but also offers a long set of functional and design-specific features. We light it up and take a closer look behind its tinted glass panels."

Take a chance on Rosewill's Valens-700?

Subject: Cases and Cooling | May 9, 2016 - 02:39 PM |
Tagged: rosewill, Valens-700, 700W, 80 Plus Gold

Saving a bit of money on your PSU can seem like a good idea but the importance of a solid PSU is often overlooked.  Rosewill has been around for quite a while but their PSU's do not tend to end up in a lot of high end rigs.  [H]ard|OCP took a look at their new Valens-700 which looks good on paper with a single 12V rail, 80 PLUS Gold certification and the hope that part of the savings is due to the non-modular design.  Unfortunately once it was strapped onto the test bed it failed many tests and did not receive a passing grade.  Check out the full review for the specifics and recommendations on better PSU at around this price point.

"While Rosewill is likely not a go-to computer power supply brand to most people, we have been surprised with Rosewill's quality on two of its PSUs over the last couple of years. Today we review an $80 700 watt Rosewill unit that is rated for Gold efficiency, and well ... that is about all that marketing has to say about its Valens-700."

Rosewill is breaking away from their previous reputation as a bare bones PSU supplier

Subject: Cases and Cooling | March 9, 2016 - 01:40 PM |
Tagged: rosewill, Quark-550, modular psu, 550W

Rosewill have grown from providing what were inexpensive PSUs with little to no extra features into something much more interesting for those who do not need a 1000W PSU.  The new Quark-550 that [H]ard|OCP recently tested is a good example, it is fully modular, it has a single 12v rail with a capacity of up to 45A and internal components from both Nippon Chemi-con and Rubycon.  Once strapped to their torture bench, [H]ard|OCP saw decent results, in line with the competition for stability and efficiency but as the unit retails for $100, roughly $20 higher than other comparable units it did not receive an award.  If you find it on sale it is still a good choice for a mid-range build.

"Rosewill was a Newegg "house brand" that has broken out to other retailers and you might have seen its name on all types of products. Today we are seeing what Rosewill accomplishes when it brands a 550 watt "Platinum" PSU. The 550W PSU market is crammed with competition...good competition at good prices."

The new and improved Rosewill RK-9000V2

Subject: General Tech | April 24, 2015 - 03:22 PM |
Tagged: rosewill, RK-9000V2, mechanical keyboard, input, cherry mx brown

The Tech Report has had some less than positive experiences with Rosewill's RK-9000, while the actual keyboard is quite functional there have been many issues with the USB connectors.  Rosewill has now released the RK-9000V2, very similar to the original model but with an improved cord and connector.  The model they were sent to review has Cherry MX brown switches, with other flavours available if you prefer a different switch.  Currently the RK-9000V sells at $99.99 for the red, black, and blue variants and $109.99 for the brown, making this an affordable option for those who want a mechanical keyboard.

Scott rightly pointed out that the 9000V2 is the third incarnation of this keyboard, he reviewed the second generation back in 2012.

If you like your gaming keyboards with light and sound ...

Tagged: input, rosewill, RGB80, mechanical keyboard, Kailh

The Rosewill RGB80 is very much a gaming keyboard, the extras like USB pass through have been eliminated as has the numpad.  It also features N-key rollover which can be toggled with a key combo if your computer has difficulty detecting the keyboard.  One unique feature are the switches which are made by Kailh as opposed to Cherry, the switches are similar to Cherry MX Blue with a bump and click when you depress a key, perhaps not the best for typing but perfect for gaming.  In addition to the PC mode there are five available gaming profiles which you can use to store macros and LED colour settings as this keyboard currently supports 228 colour choices with updated software due in the future to vastly increase that spectrum.  Head over to The Tech Report to see more on this brilliant mechanical keyboard.

Cheap Cases for Gaming PCs, Rosewill Galaxy (-01, -02, -03)

Subject: General Tech, Cases and Cooling | July 28, 2013 - 10:39 PM |
Tagged: rosewill, atx case

Rosewill, no stranger to computer cases, expands their portfolio with three cheap and feature-filled ATX mid-towers. No more than a single external 3.25" bay, and aesthetics, seem to differentiate the models from one another. Every choice has: a healthy number of internal bays, some option for external 3.5", a spot for an SSD, USB 3.0, and an expected price of $50.

rosewill-galaxy-2-3.jpg

Galaxy-02 (top-left) and Galaxy-03 (top-right) allow up to three 5.25" devices to be installed, two if you convert a bay to an external 3.5" slot using the supplied adapter. Galaxy-01 (below) includes a permanently mounted external 3.5" bay. I never really understood the advantage compared to an internal, but still easily accessible, mounting point; a toaster-like dock, attached internally to SATA, would get my attention.

Each case contains three 120mm fans with options of mounting either a fourth fan, 120mm or 140mm form factors, to the side panel. For those curious, power supplies are mounted on the bottom and draw cool air from a dust-shielded opening.

All three cases are currently available for $49.99.

A mid-weight PSU from Seasonic, the Platinum 660W

Tagged: rosewill, PSU, Platinim 660, modular psu, 80plus platinum

If the 1000W Rosewill PSU that Lee just reviewed is more power than your system needs, [H]ard|OCP has a slightly less powerful 660W 80Plus Platinum PSU you could consider that Lee has also looked at.  At $150 it is fairly expensive for a 660W PSU, but a 7 year warranty and a Platinum efficiency rating do not come cheap.  With four 6+2 PCIe connectors and up to 55A on the 12V rail and an unparalleled peak change of 0.01v this will solidly power several GPUs.  [H] was so impressed that they couldn't think of a PSU to contrast against, this unit is miles ahead of the competition when it comes to the purity of the voltages provided.

H_rosewill660.jpg

"Seasonic's new SS-660XP comes to us boasting high end PSU features in what we can consider a smaller wattage package than what we are used to seeing. This PSU has a fully modular design, great efficiency, optional Hybrid fan control allowing fanless, silent, and normal cooling modes. Does Seasonic have another winner?"

Rosewill Launches Armor Evolution Mid-Tower Case

Subject: General Tech | December 21, 2012 - 01:39 PM |
Tagged: rosewill, mid tower, case, armor evolution

Rosewill recently announced a new Armor series case called the Armor Evolution. The new mid-tower chassis is constructed of SECC steel and measures 8.74” x 19” x 22.84.” The mid-tower case supports motherboards from micro-ATX to E-ATX in size. The front IO includes power and reset buttons, two USB 3.0 ports, two USB 2.0 ports, and two audio jacks. Rosewill uses perforated metal for the ventilation panels on the sides of the case.

Rosewill packages the case with five fans, and the case supports a total of 9 fans. The pre-installed fans include:

  • 2 x 120mm red LED-lit fans on the front panel
  • 1 x 120mm top fan
  • 1 x 120mm rear fan
  • 1 x 230mm side fan (optional support for four 120mm fans on the side panel)

The case additionally supports:

  • 2 x 120mm fans on hard drive rack
  • 1 x 120mm fan on bottom of case
  • 1 x 120mm fan on the top

Internally, the Armor Evolution supports seven 3.5” drives, three 5.25” drives, E-ATX motherboards, and up to seven PCI expansion slots. Additional features include a tool-less design, CPU cutout, cable management routing holes, a bottom-mounted PSU, and water cooling grommets on the rear of the case for routing tubes outside of the case to external radiators. The Armor Evolution supports graphics cards up to 14” and CPU heatsinks up to 6.5.” Rosewill has also included removable dust filters to cut down on dust buildup.

It looks like a decent case from Rosewill that offers plenty of cooling (both air and water cooling options), and it should be competitively priced. Unfortunately, there is no official word yet on pricing or availability for the Armor Evolution case.
