So, Channel Well is quite a well-known maker. Interestingly, Hiper used to have another supplier, the less known Andyson, and I noted some problems with soldering quality of Hiper PSUs and the overall archaism of their architecture in my earlier reviews. Of course, that was the real manufacturer’s fault because it was Andyson that assembled and developed the PSUs. Hiper must have come to the same conclusion and changed the supplier.
On the circuit level, the PSU is a regular modern model of an upper mainstream class. It features dedicated voltage regulation and active PFC, supports a full range of input voltages (from 100 to 240V) and boasts high efficiency. I will check all this out in my tests, of course.
Capacitors from Samxon are installed at the PSU’s output. Their reputation is good, but the brand is not as famous as United Chemi-Con or Rubycon, so I don’t know them well enough. If you are not versed in electronics, I can tell you that failed capacitors are a common cause of death for a PSU. The service life of a capacitor depends on its temperature. And its temperature depends not only on how hot the surrounding components are but also on the manufacturing quality of the capacitor itself. The capacitor is getting hotter at work due to nonzero internal resistance. Better capacitors feature lower resistance and heat-tolerant electrolyte. As a result, their service life is longer than the typical period of use of a PSU whereas low-quality capacitors may die in 12 to 18 months. Besides, the lower the capacitor’s internal resistance, the better it filters out interference and voltage pulsations.
The PSU has an original design of the back panel. The cables go out in a few bunches rather than in one thick bunch.
The cables are divided into groups basing on the consumer: mainboard, CPU, PATA or SATA drives, graphics cards. This division doesn’t make the process of assembly much easier, though. You just save the half a minute that you’d otherwise spend to untangle the cables.
The PSU is equipped with the following cables and connectors:
- Mainboard cable with a 24-pin connector (60cm)
- CPU cable with an 8-pin connector (60cm)
- CPU cable with a 4-pin connector (60cm)
- Graphics card with an 8-pin connector (46cm)
- Graphics card with a 6-pin connector (56cm)
- Cable with one Molex connector (34cm)
- Cable with one Molex connector (44cm)
- Cable with one Molex connector (64cm)
- Two cables with two SATA power connectors on each (49+15cm)
- USB cable (65cm)
The cables for PATA drives are somewhat odd as they only offer one connector each. Hiper suggests that you use splitters of a specific design:
Included with the PSU are two Molex→2xMolex splitters (one is shown in the photo above) and two Molex→2xMolex+1xFDD adapters (you can use them to power up your floppy drive).
These splitters help avoid the mess of cables for unnecessary devices (a modern computer system doesn’t have any PATA drives at all), but it is just a compromise in comparison with fully detachable cables. The splitters make it handy to connect drives located no closer than one bay apart from each other as shown in the photo above.
Besides everything else, the box contains an adapter from an 8-pin to a 6-pin connector for graphics cards.
The PSU is cooled with a 140x140x25mm fan (Yate Loon D14SH-12).
The PSU has four “virtual” +12V output lines with a combined load of 50A (600W). The load capacity of the +3.3V and +5V rails is also high (it is usually no higher than 130-140W with other PSUs). Well, the practical load on these rails should not be higher than 50-60W unless you install the 4M630 into an archaic computer that is powered mostly by these two rails.
Besides continuous, the peak output power of the PSU is also specified. It equals 870W. This parameter is not explained, so I guess this is the output power the PSU can yield for no longer than one minute.
