At first glance, there’s no denying that this is a budget-oriented PSU. With that being said, it doesn’t look all that bad.
It does have some stylish lines embossed into the side of the casing.
The modular interface allows you to connect up to four cables. On my first pass through taking the product shots, I thought my eyes were playing games with me. It looked like I was able to see the bare metal trying to show through in areas.
I decided to go back and retake the shots using a different background and a few different settings on the camera. That decision was the right move, seeing how it has changed my outlook on the overall finish of the Cooler Master G650M.
The rear of the unit utilizes the standard hexagon patterned venting we see on most units. Those little fuzzies from my sheet at the bottom of the image are annoying though.
On the fan side of the casing, we can see a little of what I was seeing in the other shots. However, with a little more time and vigilance I was able to spot my error and correct it. In this photo, you can see a few spots where the speckled paint looks to be finer than the other areas. Ok, enough about the paint lets move on to the fan grill. Cooler Master uses a larger hexagon pattern here, similar to what we see on the rear of a lot of PSU’s.
On the bottom of the PSU casing, we find the specification label. It provides us with most of the information we need for our testing purposes. AC input info., DC output info., but what I didn’t find again was the operating temperature. Thankfully, it was listed in the user manual. Personally, I think that should have been on the box as well.
|G650M – DC Output|
|Max Power @ 40°C||120W||624W||3.6W||12.5W|
With the CM G650M having a 40°C temperature rating at maximum power, I might have to utilize my auxiliary fans on the hot box to keep the temps down. The SunMoon SM-5500 has no problem producing heat, especially when you fire up some of the larger PSU’s.
Here we have a shot of the ATX 24-Pin connector.
This unit only has an ATX 4+4-Pin connector.
We have two PCI-e cables, both with two 6+2-Pin connectors each.
We have two peripheral cables. One has three 5.25″ connectors, and the other has three 5.25″ and one 3.5″ connector.
We have two SATA cables as well. Both have four SATA connectors each.
|G650M – Cabling|
|Type of Cable||Length from PSU|
|20+4 pin ATX connector||550 mm|
|4+4 pin CPU||610 mm|
|6+2 pin PCI-e, 6+2 pin PCI-e||600+120 mm|
|6+2 pin PCI-e, 6+2 pin PCI-e||500+120 mm|
|Unit Dimensions (L x W x H)|
|140 mm x 150 mm x 86 mm|
Here we have all the cables listed out showing their lengths and connectors per cable. The limited cable/connector options here are definitely a result of the cost-cutting that comes with these budget-minded units. At 650W though, we should be good with Cooler Master’s configuration. The G650M is on the small side since it utilizes a 120mm fan, which could be ideal for a build that has limited space for the PSU.
