Tale: The Kamariki and the Wolf

External

True to our promise, we now turn to our modular 450 W Kamariki 4. Whether we need the modular version is a category of individual questions to decide. As the owner of a Zalman ZM600-HP, I have a positive opinion about modular power supplies, as space is saved by omitting unnecessary cables, used cables are easier to arrange, in short, we get a more aesthetically pleasing end result. Of course, this only matters if we need to do so, such as having a plexiglass side panel housing or assembling our machine a lot, but it’s also inconceivable that someone simply loves order in the engine room as well. However, what has been said above is, in my opinion, only valid if there are relatively few devices installed in the housing. In my case, for example, a story was blown out with an HDD, an ODD, and a VGA, so I could barely plug in a cable to the power supply because it simply didn’t need more. If, on the other hand, we have a lot of devices, we will not be able to avoid the use of many cables, so the importance of modularity is radically reduced, as a connected cable is aesthetically the same during use as if it were soldered there.

After this little detour, take a look at the KMRK4-P-450A box. If we had to rate it at least 4, the design is pleasing, the box is massive and we can find all the information you need on the back with subtleties such as a speed / noise ratio graph. Inside, the placement of the contents is also demanding, the food is protected with a snap bag from the dangers lurking on it during transport.

The glowing gray color of the unit is also attractive and elegant, of course we have seen it elsewhere. However, we have not encountered three things elsewhere (or at least do not remember them). The front is a specially shaped rear ventilation grille. Nowadays, the beehive frenzy is rampant, the shape of the nest of absolute buzz dictates fashion, while Scythe has decided not to line up and come up with a unique pattern for herself. The shape of the holes might be like small leaf blues, the grid between them is thin and the whole surface is large, so there will definitely be no problem with ventilation (the manufacturer is notorious for under-designing its cooling anyway). Another point of interest is Scythe Kaze Jyu, which measures 10 cm. When everyone today forces 12-inch and even 14-cm air vents, Kamariki 4 thinks otherwise. We wouldn’t be so surprised if he was right, or at least not disadvantaged by it.

The last - and perhaps most surprising - innovation is the three modular fan connectors in addition to the modular power connectors (extension cables are also included in the package). Yes, it is! Kamariki 4 power supplies can be connected to three air circulators, which are intended for system ventilation purposes, and which are controlled by the power supply as a function of the load on it. If we look at it, the idea makes perfect sense, as the higher load on the unit means that the main components of the machine (CPU, VGA) work at a tense pace, thus generating more heat around them. In this case, the speed of the fans connected to the power supply will increase and the hot situation will be handled.

Five of the modular connectors can be found on the back, of which the PCI-E cable can be connected to the blue color, at the end of which a 6 + 2 pin connector is mounted. Cables with SATA and molex connectors can be connected separately to the remaining four locations. Only the 20 + 4-pin and 4 + 4-pin power connectors were fixed to the power supply. According to these features, the package includes a mains power cable, a PCI-E cable, two molex cables with three molex connectors and one FDD connector each, and two SATA cables, each with three chucks. The four plate screws required for mounting, the user manual, and the three fan extension cables were not left out either.

Internal

We couldn’t let our patient go without undergoing exploratory surgery on her. The interior is airy, there is room for air to flow, the ribs are not very large, graceful, the color of the PCB is black. On the input side, a Ruby's 330 µF buffer condition certified to 85 ° C performs the primary work, while on the other side, the 105 µF PEC capacitors, which can withstand 2200 ° C on the output side, do the job.

The fan is the already mentioned Scythe Kaze Jyu, with a size of 10 cm and a maximum speed of 1350 rpm, with a maximum noise output of 20,7 dB.

Nowadays, the capacity of the 12 V branches of the power supplies is of paramount importance. Well, the Kamariki Plug-in 450 W has two 12 V branches that can be loaded with 18 A each, with a total maximum power of 400 W.
