The Cooler Master V650 Gold V2 White Edition 650W unit is different in contrast to other power supplies as it has a white appearance, as the name implies. This ATX power supply is 16.0cm long, which is about a centimeter longer than other comparable modular PSUs like the XPG Core Reactor 750W and Corsair CX750F RGB 750W. Think of this as a modular, higher efficiency version of the Cooler Master MWE 650 White V2 650W. Most modular power supplies are longer than non-modular units to accommodate its connector board at the back. For an average ATX case, this length should be small enough to fit easily. If anything, you may find some length issues with respect to the included cables.
On the other side of the power supply, there is a panel indentation to add a small difference in appearance compared to other supplies. The top shows a relatively large opening with a honeycomb mesh with a hexagon pattern to allow for airflow. The Cooler Master logo is placed prominently in the center of the grill. A 135mm fan sits underneath this area for the intake of air. Four screws surround the top area to ensure the whole power supply is connected and another four screws are found for mounting the fan to the top.
Likewise, to the top of the power supply, we find a honeycomb mesh with a hexagonal pattern on the back. This design is often used because it maximizes airflow while minimizing air resistance without compromising on the general build quality. This ventilation area is important as it lets heat flow out of the back. In addition to the back of the power supply, we find not only the power switch, but also the hybrid mode toggle. Toggling on hybrid will allow the fan to stop when the power supply is under a low load and temperature, while normal mode will leave the fan on all the time.
As with many other power supplies we have covered here at APH Networks, the Cooler Master V650 Gold V2 White Edition 650W is a fully modular power supply. This means all the cables are completely detachable from the main unit. While not being completely necessary as the ATX 24-pin and ATX 4-pin/EPS 8-pin are practically always being used, it may still be helpful when building your computer.
The rear cable connection panel has a very reasonable layout, keeping similar connectors grouped together. Each group is labeled so you know where to plug in each of your cables. On the left, we have two connector blocks, a 10-pin and an 18-pin, both in combination for the ATX 24-pin motherboard connector. Following that on the right, we have four 8-pin connectors for the CPU or any PCIe slots in the top row. On the bottom row, we have three 5-pin connections for peripheral outputs such as SATA or Molex connections. Incompatible outputs will not physically fit into each other, so I think Cooler Master has done an excellent job in designing the cable connection panel. This is a reasonable amount of plugs given the wattage of this unit.
Overall, the external build quality of the Cooler Master V650 Gold V2 White Edition 650W is quite good. All parts seem to fit tightly together. All of the edges are rounded enough to ensure the user will not accidentally cut themselves along the edges. The general frame was well done and well thought out.
The voltage specification label on the top panel of the Cooler Master V650 Gold V2 White Edition 650W shows us more information about the power supply. We can see in the image above, there are two main virtual rails. Up to 20A can be delivered using the +3.3V rail for a total of 66W, while the 20A on the +5V rail brings the output to 100W. The total combined output for the +3.3V and +5V rail is 120W. What this means is your power allocation combination has to fall within the limits of these specifications. A single power +12V rail delivers up to 54.1A or 649.2W to reduce operating overhead compared to multiple +12V rails. Unsurprisingly, the combined power output for the whole V650 Gold V2 White Edition is 650W. Once again, your power distribution in your system must fall within the limits provided –- it must not exceed 66W on the +3.3V rail, 100W on the +5V rail and 120W for both, 649.2W on the +12V rail, and 650W combined between the +12V and +3.3/+5V rails. This configuration allows fairly flexible power demands and should be sufficient to accommodate most users. The +3.3V and +5V rail outputs are on an average side for a 650W power supply.
The Cooler Master V650 Gold V2 White Edition 650W is 80 Plus Gold certified, which means that it is certified to be at least 87%, 90%, 87% efficient at 20%, 50%, and 100% load, respectively. Higher certifications available at press time include 80 Plus Platinum and 80 Plus Titanium.
There are a total of eight modular cables included out of the box alongside a power cord. These cables are all white to match the color of the power supply, which is something I personally appreciate as some white power supplies come with black cables. Having white cables simply helps keep a consistent theme in your build. The PCI Express cables are fattened up to 16 AWG, while the rest of them are all 18 AWG including the ATX 24-pin and ATX/EPS 8-pin cables. All modular cables are flat and easy to bend, making them extremely easy to work with as they can be more simply routed.
The following modular cables are included out of the box:
- 1x ATX 20+4 pin, 65.0cm
- 2x ATX/EPS 4+4 pin, 65.0cm
- 2x PCIe 6+2 pin, 2 connectors each, 50.0cm to first connector, 12.0cm spacing thereafter
- 2x SATA, 4 connectors each, 50.0cm to first connector, 11.5cm spacing thereafter
- 1x Molex, 4 connectors, 50.0cm to first connector, 11.5cm spacing thereafter
These cables are pretty standard in length compare to other modular ATX power supplies. I do not have many complaints about these cables as I have found they are long enough to route efficiently, while not having too much extra cable to manage.
