These cable extensions made my husband’s PC build look so clean and professional. The sleeving feels premium, super flexible for routing, and the black finish matches perfectly with his setup. Huge improvement for cable management

Not always needed, but well made.
Adapters like this aren’t always needed and this one won’t necessarily save you space, but if you’re not into using cable combs or have cables that can’t use them this is a more elegant solution rather than making the typical 180 degree bend. Additionally the added capacitors, which shouldn’t be necessary on most systems, can be seen as an added benefit to prevent heavy malfunction when running your rig off of a more sketchy power grid. Given the price difference I’d say having the extra capacitors is a valuable trade.

It works. It’s tall. It’s clean. It’s a pain to plug in and unplug
Yes it is a tall attachment. Yes it is hard to plug in and unplug. But. It’s is perfect for having a cleaner setup. Especially when you are limited on cable space. It sits just as high as my tridents rgb ram. So what. It looks sleek.

I will never not use this in another build ever again
Guys it is entirely possible this little device saved this entire pc build from being completely fried. Not long ago I built a rig for someone a fairly custom 1 off at that BUT. I have several things working against me in this case one of witch is directly my fault. I build and work in a less than sound environment there is heavy moisture in the air witch is bad and ad to that the electricity down here is BEYOND unstable any little thing flickers the power down here any time something turns on or off or even switches power fazes in the house directly translates to a power flicker in this room you can understand how that's not ideal for sensitive electronics sometimes the flickers would just blink the system other times completely reboot it. but there is little I can do about my environment its the only space in the house I can work in 3rd I foolishly purchased a less than reputable power supply for this build something I normally don't do but I had some specific ideas for this build that later changed. finally after a power flicker the system shut down and wouldnt reboot or power back up in any way it took some doing to get it to come back. I'm convinced all these factors led to me nearly burning out the mother board possibly the whole system as it is several power headers are fried and I'm still trying to determine if any of the ram was damaged or just the rams slots hopefully just the ram slots. I thought the CPU died for a secant to. but I'm am firmly convinced I would have lost every component in this rig. as it is the mother board still functions......mostly. I will be replacing it however just to be completely safe for the person that is actually going to be using this machine as well as the power supply. as you can see from the pictures above there is no way a standard 24 pin plug was making it into the mother board I used the cooler master and a cy lower profile 90 degree adaptor in a horse shew configuration I would have used two cooler masters but they rise up to high for this build ( I WOULD LIKE TO SEE COOLERMASTER COME UP WITH BOTH A LOW PROFIL AND A HORSE SHEW SINGLE PIECE CONFIGURATION) I would use them. and if they ever got the wild hair GPU and CPU 90 degree power adaptors I would buy them especially the CPU nobody makes CPU adaptor at all that I can find at all. after this experience i will be investing in some UPS devices something ells I should have been using all along as well PS know your cases and mother boards or bring your own Dremel. You'll need it if you don't make sure they pass directly over the grommet hole

Looks good and helps hide the power cable to mobo
This product is great and helped my build keep the huge power cable to the motherboard hidden. I liked this route instead of getting sleeved cables. My pic isn't the best example, but it does hide the cable very well in my case and doesn't get in the way of anything despite how tall it is. Seems to be built well - feels strong, but this brings me to the only bad thing in my opinion: it's a tight fit. Installation is very strait-forward, but it will be a lot harder to uninstall as the fittings are very tight both to the motherboard and the cable to your PSU. When I first installed it I pushed the cable into the adapter maybe too hard since it's so tight and my finger slid off and the edge which split the tip of my finger open hah. Be patient if you are installing/removing this from the motherboard. Even tho this item poked a hole in my finger I'd still recommend it if you're looking for ways to make your build look clean.

Helped alleviate some cable and motherboard tension
Great simple product from Cooler Master, been a huge fan of their simple yet intuitive items. First off, the entire thing is plastic. Light, but the build quality is great, nice and sturdy. It could be considered a tad bulky in some build situations, but this is minor and could be a necessary part of the design to house the connections and capacitor while maintaining the subtle design. I don't think it is a one of a kind item, but it definitely looks cleaner and more professional than the other 90 degree adapters I've seen. The 'Built-in Capacitor' is definitely a nice touch if you're just looking for something extra to help with power fluctuations and a premium feeling build. It has a warranty, thank you for this Cooler Master. In short, it helped me in my build because my cables were like barely too short coming from behind the motherboard and that put some strain on everything that I did not like because they had to wrap all the way around. It alleviated that and made everything fit in my case perfectly by allowing it to plug in from the side instead, this also put the cables out of view threw the side panel cleaning up my cable management a bit.

It's tall. Make sure your case supports the height.
Works as advertised but I should have checked the dimensions because this thing is pretty tall. It was taller than the RAM I have which isn't really low profile RAM (non-LED Ballistix). Part of the size is likely due to the inclusion of capacitors (in the version that has them). I have a Corsair 4000D and the vertical cable management slot sits pretty close to the motherboard (a fairly standard ATX motherboard). I was hoping this would let me run the cable more or less straight out of the slot and into the adapter but it's so tall it ended up kinking the cable even more awkwardly than without it. Your mileage may vary and some 24-pin PSU cables may work better than others. It's was also extremely tight fitting. 24-pin connectors can be kind of like that normally but this was extraordinarily difficult to fit and remove. It seems well built and worked just fine. Ultimately, I removed it as it didn't provide the results I wanted. Hopefully they'll release a lower profile one in the future.

Black/white sleeved cables.
When straightened out, some cables seem to be just ever-so-slightly longer than others in the 24 pin extension. Aside from that, they’re nice, thick, sturdy wires. They stay where you bend them and look phenomenal. I just wish they came in more patterns than just w/b/w/b/w/b/w. Not a very appealing design, but works for my color scheme. Oh well.
