The more brands come to the PSU market and the tougher the competition becomes, the wider various marketing inventions are employed besides just technical advances and innovations.
Unfortunately, besides experimenting with colorful box designs and accessories (well, it’s hard to expand a PSU’s accessories set beyond the customary set of a cable, a couple of braces, and a handful of stickers), the marketing department comes up with a technical lingo to bewilder the customer with mysterious terms and abbreviations. Every box and instruction shows a long list of employed technologies, the point of some of which may be distorted almost to the opposite.
That’s why I’m going to walk you through some of the technologies (or what the PSU manufacturers regard as such) most frequently mentioned on boxes with modern power supplies. And then I’ll put PSUs with such technologies to practical tests.
You can find the details on the latest PSU technologies as well as the detailed description of the 6 PSU models from Antec, CoolerMaster, Corsair and High Power in our previous article called ATX Power Supply Units Roundup. Part V.
Hiper Type M HPU-4M530-PU V1 (530W)
Power supplies from Hiper can be easily identified by their meshed cases. In PSUs from other manufacturers there is usually a vent grid in the rear panel plus a couple of small slits opposite to the hottest components. Here, the case is all meshed. Well, I think this has little to do with cooling. That’s rather a matter of aesthetics.
Hiper promotes its Type M series as a cheap version of the Type R series, without detachable cables.
It is all ordinary inside. An active PFC device is located on a separate card. In my previous article I complained that that card was soldered untidily, but it is all very neat here.
Otherwise, the PSU circuit design doesn’t differ much visually from the Type R series. In spite of its active PFC, the PSU is intended for an input voltage of 220V only. Another model, intended for an input voltage of 115V, is produced for the US market.
The PSU is declared to comply with the ATX12V 2.2 standard. It has two +12V lines (separated “virtually”, as usual) with a combined load current up to 30A. The load capacity of the +3.3V and +5V lines is not low, either.
A peak output power of 580W is specified, too, but the conditions under which the PSU can yield it are not declared (the maximum duration of operation under the peak output power is usually specified). Generally speaking, this parameter is rather a marketing trick. Surely, each high-quality power supply is made with some reserve so that it can yield a short-term output power higher than the maximum sustained one without breaking down.
The PSU is equipped with the following cables and connectors:
- Mainboard cable with a 20+4 connector (44cm long)
- CPU cable with a 4-pin connector (48cm)
- Graphics card cable with a 6-pin connector (47cm)
- Two cables with four Molex connectors and one floppy mini-plug on each (47cm from the PSU to the first connector and 15cm more to each next one)
- One cable with two SATA power connectors (46cm+14cm)
An adapter from two Molex into one graphics card connector is enclosed with the PSU. It is meant for use with SLI or CrossFire configurations.
