Hiper M-1000ME (1000W)
Hiper is not a frequent visitor of our labs although its power supplies are widespread and popular among end-users. I will try to make my amends to the company now.
The PSU box is designed in Hiper’s style: the meshed pattern on the front panel resembles the mesh Hiper’s PSUs are usually made from.
The meshed panels are actually a questionable solution. The position of the heatsinks inside the PSU is anyway optimized for a lengthwise flow of air. And I don’t think the cooling of the PSU improves from the fact that some of the hot air goes back into the system case.
The number of vent holes in the external panel of the PSU is small and its top is even blank completely, while a considerable portion of the bottom part of that panel is occupied by the mains socket and the On/Off switch. Perhaps this is done for the sake of unification with Hiper’s PSUs that have an integrated USB hub whose ports are installed in the top part of the panel, but I guess the manufacturer shouldn’t have reduced the airflow in such a way.
The cables are fixed but go out of the PSU housing in a few groups, each group through its own hole. This helps reduce the mess of cables somewhat but does not affect the ease of assembly.
The PSU is equipped with the following cables and connectors:
- Mainboard cable with a 24-pin connector (60cm)
- CPU cable with a 4-pin connector (63cm)
- CPU cable with an 8-pin connector (58cm)
- Two graphics card cables with one 6+2-pin and one 6-pin connector on each (56+8cm)
- Graphics card cable with one 6+2-pin and one 6-pin connector (62+8cm)
- One cable with two SATA power plugs (55+16cm)
- One cable with two SATA power plugs (61+16cm)
- One cable with one Molex connector (37cm)
- One cable with one Molex connector (48cm)
- One cable with one Molex connector (68cm)
This is a standard selection and I don’t see anything to complain at. It is good that the cables with HDD connectors differ in length as you can choose what cable suits your particular system case. The connectors for PATA drives are single: Hiper seems to imply that this type of cable may only be necessary for but a single device. The PATA standard having become outdated, there is no need to put a bunch of connectors on each power cable.
The PSU is a rather typical modern model. A few other makers use the same circuit design and component layout. I don’t have any direct evidence as to what company makes the M-1000ME for Hiper, but I have reasons to think that it is Sirtec whose products can be found under the brands of Chieftec and High Power as well.
The PSU features dedicated voltage regulation based on magnetic amplifiers.
The M-1000ME has standard characteristics. Having a max output power of 1000W, it can yield 900W via its +12V rail which is split into four virtual output lines with different current limitations. The peak output power of 1100W must be the load the PSU can work under for a limited period of time, usually no more than 1 minute.
Together with my UPS this power supply worked at loads up to 375W when powered by the mains. But when powered by the batteries, the pair was only stable at loads of 250W or lower. Thus, you need an UPS with a much larger wattage rating or with sinusoidal output voltage for this power supply.
Output Voltage Ripple
The PSU boasts excellent voltage stability at any permissible load. The +12V rail is always within 3% from the nominal value whereas the +5V and +3.3V rails deflect by no more than 4%.
The PSU is cooled by a 135x135x25mm fan from Globe Fan. One fourth of the fan is covered with a celluloid triangle in order to increase the pressure at the back of the PSU. It is from there that the air should go into the front part of the PSU case and leave it. Without that, the cooling of the back of the PSU would be somewhat worse.
The PSU is rather quiet at loads up to 300W but then begins to accelerate its fan in a linear way. It becomes really noisy at loads of 600W and more – and most of the noise is produced by the air passing through the perforated side panels.
Efficiency and Power Factor
The maximum efficiency is 87%, which is average for today’s PSUs. The power factor is surprisingly low, not reaching 0.9 even at a load of 200W.
The standby source is rated for a current up to 3A and copes with that load well. Its output voltage is never lower than 5V.
The Hiper M-1000ME can actually be described as the above-discussed model from Gigabyte. It is good but lacks a special feature, something that would provoke you to look for this specific model among the numerous alternatives. Good electrical parameters, average noise comfort and a standard selection of cables and connectors. That’s all I can say about the Hiper M-1000ME.
