You could purchase an amazing video card and might not be getting the most out of its performance. This is where a sufficient power supply comes in, and companies, such as Rosewill, provide the necessary hardware to get the most out of your equipment. The company has released two new power supplies to make sure your rig reaches its potential with the Capstone-G1200 and Quark-1200. Both are similar in stats, as they both offer a wide variety of wattage ranging from 550 watts up to 1200 watts. Additionally, both of these models are 80 Plus Gold certified, feature strong fans, and offer one single +12V rail for gaming. It is safe to say that both models offer optimum performance for SLI and CrossFire-ready setups.
Our review model that was provided to us was the Capstone-G1200. My previous power supply was a Rosewill, as well, and featured perks such as lighting, a fan, and fan control button. The Capstone keeps things simple as it is all black, with no lighting options, and purely just a power button on the back. It is modular, which allows you to only plug in the cables that are needed. This allows space conservation inside the PC tower. The unit stays very quiet with its 135mm silent fan, and most importantly, stays cool with proper ventilation. Installation, however, did not work well with my setup. I have a mid-tower, and I was unable to adjust the cables at the point of connection to squeeze behind the DVD drive. The cables, especially the power cable for the motherboard, are extremely thick and tough to maneuver. This most likely would not be an issue with a bigger setup.
My setup is not top of the line and is a bit dated. I was personally worried about the thought of a 1200W power supply bricking my motherboard (which is a Biostar TA75+). Thankfully, the power supply offers over current, voltage, temperature, power, short circuit, and under voltage protection. The board is ATX 12V v2.3 ready, supports EPS 12V 2.92, and is backwards compatible with ATX 12V 2.01. However, there are times where my system would not boot the motherboard. It would boot the peripherals, but it would not hit the POST with no notification on screen. This could be due to one of the protection modes, and most likely due to the dated motherboard. This might raise a red flag for users with an older rig.
Testing out some games on the system (which is running one AMD R9 280X) did see some slight improvement in the games. The Capstone features one 12V rail that runs at 100 amps. That might seem a bit overkill as it is designed to support SLI or CrossFire setups. On the other spectrum, some people running those setups prefer to run multiple rails with a dedicated amount of amperage going to each card. While there are plenty of amps to go around on that one 12V rail, some may not feel it is getting maximum efficiency if it is having to share.
The MSRP for the Capstone-G1200 is $219.99, but can currently be had on Newegg at $169.99. The Capstone is a very solid unit, but fits in a tight window. It more than gets the job done for people with a newer and somewhat beefy rig, but lacks options. It sets out to get the job done with no flash, and the model succeeds at doing this. While the unit supports SLI and CrossFire, it might be best used with one top of the line card since it features only one 12V rail with such a high output of amps. The original MSRP might be a bit much for a unit that lacks flash. Otherwise, Rosewill set out to keep things simple with its Capstone-G1200 Power Supply, and succeeded in the end.
+ Simplistic, straight forward design
+ Delivers on performance
+ Stays cool and quiet
– Tight fit in smaller cases
– Lacks options for the price
– Single 12V rail may not be what everyone is looking for
