The second Hiper product in this review comes from the senior K series and is in fact the first original model in it because the K700 model is based on the M700 that has a simpler circuit design and is similar to the above-discussed M600. The only difference of the K700 from the M700 is its modular design and K series packaging.
As opposed to the plain cardboard packaging of Hiper’s less advanced products, the K series comes in a plastic box that you may find handy for storing tools or something. The accessories are the same as those included with the M600: two sets of crews (ordinary and thumbscrews), a pack of cable straps, and a user manual. There are also detachable cables in the box.
The K800 has a rather standard appearance and differs from the above-discussed M600 in nuances only.
You can see connectors for detachable cables and vent grids in the side panels. The fan's impeller is painted silvery; the fan is highlighted in blue.
The On/Off switch has become larger and is located next to the mains connector.
Like the first product from Hiper in this review, the K800 is based on Andyson's Performance platform, but this time around it's the more advanced E series.
It’s easy to see that the PCB is larger and has higher component density.
This PSU features dedicated voltage regulation based on DC-DC converters soldered on two individual cards above the +12V choke.
The PSU uses Teapo capacitors everywhere, including its output. Like the previous PSUs, this is has active PFC.
Thus, the Hiper K800 is the most up-to-date product among the tested six in terms of technologies, but let’s see how well those technologies are implemented in it.
Cables and Connectors
The K800 is equipped with the following cables and connectors:
- One mainboard cable with a 20+4-pin connector (52 cm)
- One mainboard cable with a 4+4-pin connector (55 cm)
- One mainboard cable with an 8-pin connector (55 cm)
- Two connectors for graphics card cables
- Four connectors for peripheral power cables
- Included with the PSU are:
- Two graphics card cables with two 6+2-pin connectors on each (50+15 cm)
- Two cables with three PATA power connectors and one floppy-drive plug on each (50+15+15+15 cm)
- Two cables with four SATA power connector on each (50+15+15+15 cm)
The cables aren’t very long. The mainboard’s 4+4-pin cable is going to be too short to be hidden behind the mainboard’s mounting plate in a system case with a bottom PSU bay. It’s impossible to plug a peripheral power cable into a graphics card cable’s connector by mistake because the keys differ.
Like the Hiper M600, the K800 has a rather low load capacity of the +12V rail: only 648 out of its full 800 watts (i.e. 81%).
The combined load on the +12V, +5V and +3.3V rails must not be higher than 779 watts; the remaining 21 watts refer to the -12V line and the +5V standby source.
The PSU can cope with a short-term load of 850 watts.
