Rosewill Quark 1000 Power Supply Review

High Performance At A Fair Price

Yet again, Rosewill managed to deliver a very good PSU that offers top-notch performance and nice features, such as fully modular cabling and Japanese electrolytic capacitors. Although the company didn't manage to offer a significantly lower price than its competitors, the Quark 1000 is still reasonable, especially considering that the platform has an increased production cost due to its high-quality components. We believe that Rosewill is now well established in the tough PSU market and ready to meet the competition, even in this high-end PSU category, where big companies like Corsair, EVGA and Seasonic dominate the field. It is nice to see new players with fresh designs in this category; it ultimately will benefit consumers as well.

The Quark 1000 comes with a bevy of connectors and, along with its 1kW capacity, will easily support a potent gaming system with multiple, high-end graphics cards installed. Given that an Nvidia GeForce GTX 980 needs around 200W in worst-case scenarios, a 1kW PSU can easily support up to three of them, along with a strong CPU and the remaining system components. If you want to build a four-way SLI system, you should go with the Quark 1200 to be on the safe side. If you prefer AMD's offerings, 1kW keeps you around two Radeon R9 290X GPUs, given that each of them needs around 310W at peak load.

Then again, you'll have to make some compromises with regard to noise. Or you can just crank up the volume of your speakers when you stress the PSU, since its fan is noisy at high loads. If Rosewill had offered a semi-passive mode under light/medium loads, things would have been much better. However, under stressful conditions, the situation wouldn't have changed, given the position of the +12V FETs. In units with 1kW of capacity or more, you simply can't expect silent operation. Even the most efficient products generate a significant amount of heat, so strong airflow is required.

    I don't know of Rosewill is any better then it was a few years ago. I had friends with a rosewill PSU and it baked big time. Maybe they are better now. But I would stick with EVGA or another well known good company!!!

    i wouldnt hesitate to replace my ~7y/o antec TP750 with a nice rosewill capstone unit when the time comes. in fact, thats essentially my plan. would i throw any rosewill unit in my rig/s? no i wouldnt, but every manufacturer i can think of has units that are less than desirable. rosewill has a come a long long way the last few years

    Obviously EVGA has amazing brand name and they deserve it because of their level of service. However as far as i know EVGA does not have any PSU making plants, they simply rebrand a unit made by Seaconic or another OEM. Many companies do that, so you can probably buy exactly the same unit from a different brand.

    I am not sure if Rosewill builds or rebrands, but i had their products and they are not bad, i personally have not had any issues.

    Several Rosewill PSUs are build by Super Flower, the same OEM that also makes most of EVGA's offerings.

    I duno if their large ones are as good. But ive had a 550 watt running in this computer for 6.5 years now with no problem. This is the first roswell one i had tried. Thats the longest ive ever stayed on the same power supply.(In the past it was either fry, or had to upgrade the size because of ever increasing component power usage)

    companies that manufacture a Rosewill psu

    Like every company that wants to do well into this market Rosewill doesn't rely on only one manufacturer. They had strong ties with Super Flower in the past however they decided to go with other OEMs as well, since SF became so popular and cannot meet the demands of all the companies that want their products.

    Does anyone actually do OCP, OVP, OPP / OLP, OTP, UVP, SCP, and
    NLO? (Something of a rhetorical question), short answer from google is no...

    Also, why is the list graphical? I'd like to have a character list to search through...
