A Closer Look
The marketing team at Cougar did a nice job on the graphics for the Cougar CMX V3 850W Power Supply. The design is elegant and not over the top. The front of the box clearly shows the power supply, while the back of the box lists out the specifications and certifications.
The Cougar CMX V3 850W Power Supply’s design is well done and not over the top. The metallic orange and black color scheme should go well in most builds. Cougar made sure to put their name on each side of the power supply, but has printed them inverse of each other. This way no matter how the power supply is installed, either with the fan up or the fan down, their name will always be shown right side up.
Over the last few years case modding has made a major resurgence; which means more and more cases are either being modded by the user or the cases come modded from the factory. Part of case modding is showing off the internal components. Component manufactures have taken notice of this and have started making the appearance of the components look cleaner and more refined. Cougar has done a nice job with the color scheme of the Cougar CMX V3 850W Power Supply.
As a power supply converts 120 AC volts to 12 DC volts and delivers power to the components heat is generated by the internal parts of the power supply. An open mesh design on the back of the Cougar CMX V3 850W Power Supply ensures the heat generated can escape the power supply with the aid of the 140 mm fan. The fan grill on the Cougar CMX V3 850W Power Supply has a similar mesh in order to get the maximum amount of air into the power supply.
The Cougar CMX V3 850W Power Supply is a semi-modular design. This means the peripherals and the PCI-E cables can be removed from the power supply. A fully modular power supply means the 24 pin motherboard cable and 8 pin CPU cable can be removed. There has been some discussion lately about which is more desirable; semi-modular or fully modular. Honestly, I can think of very few extreme cases where a fully modular power supply is needed. In the course of a normal installation, when do you NOT use the 24 pin and 8 pin connectors. The only gripe I have on this part of the power supply is the lack of a grommet on the hole for the main power lead. Even though the cable has a sleeve, I’d like to see added protection with a grommet.
Finally, we come to the information sticker on the Cougar CMX V3 850W Power Supply. The 3.3 volt & 5 volt rails are capable of 25 amps each. This power supply is a dual 12 volt rail design. Each of the 12 volt rails has a max amperage rating of 50 amps.
Internally the Cougar CMX V3 850W Power Supply’s component arrangement layout should maximize cooling. The heatsinks run parallel to each other. This helps to eliminate hot air getting trapped between components and maximizes airflow between components. The 140 mm fan is PWM controlled by the power supply and thankfully is not a sleeve bearing, but ball bearing. Ball bearing fans tend to last longer and run a bit quieter over time than sleeve bearing fans. When a power supply fan goes out, as I have seen a nasty shower of sparks and smoke can make for a interesting day when the power supply finally lets go.Article Index:
