Connectors & cabling
All but four wires are a puny 20AWG, and there’s only one zip tie holding each cable cluster together, no sleeving. That means that the cables will definitely get tangled up sooner or later. Those four wires coming off of the first SATA connector to the single molex connector on one of the two cable clusters is 18 AWG. This is funny, given how that wires to the SATA connector itself are 20AWG. Most likely they just used whichever wires they had laying around…
In total, we have:
- 1× Main ATX (20+4pin): 40 cm
- 1× ATX 12 V (4+4pin): 41 cm
- 1× PCIe (6pin): 42 cm
- 3× SATA: 1× 40 cm, 1× 41 cm, 1× 55 cm
- 1× Peripheral molex: 1× 55 cm
Casing & cooling
The metal casing of the XP400R6 uses 1mm SECC steel with matte black finish (most likely powder-coated). It is rather thick, but on the other hand the fan mounting positions just consist of beveled edges that have been threaded. That means that there’s a space between the fan itself and the metal cover. Because of this gap, the chassis can’t reinforce itself with the grill, which could cause it to easily deform if pressure is applied.
The only good thing here though is that they used a wire fan grill which should allow for more airflow with less noise, and also that there’s no plastic sheet underneath the fan. As for the exhaust, it’s composed of ordinary hexagonal holes punched into the metal. There should be enough airflow throughout this whole side, including the space around the AC inlet, so I expect that there won’t be any trapped pockets of hot air inside the unit.
The CP400R6 uses a red 120mm Evercool fan, the EFS-12E12L. I couldn’t find much information about this model, other than that it spins at 1400 RPM. However, cross-referencing it to other Evercool fans, it seems to be similar to the EC12025SL12X which has a rated speed of 1400 RPM for the 0.16A version with an airflow rating of 51.87 CFM and a noise level of “<29” dBA.
