Review of Ocypus Iota 1200 PSU
Ocypus is a new name in the PC power supply market, and today we are testing one of the most powerful models of the brand, the Iota 1200, a 1200-watt ATX 3.1 power supply. This is a fully modular model with all pluggable cables, a hybrid fan mode and an 80Plus Gold certificate, which is an indicator that inside The PSU has good, high-quality components installed.
What is interesting about this model? Well, first of all, support for ATX 3.1 and PCIe Gen 5.1, that is, consider that for the next few years this PSU should cover the needs of a powerful gaming computer or workstation, for example, for neural networks, but this is only if you choose previous-generation GPUs that you plan to connect via PCI-E 8 pin or adapters.
The cables are modest, even for models of similar power: 1 PCI Express 5.1 connector (up to 600 watts) for a video card, 3 6+2 Pin PCI Express connectors for previous-generation GPUs, and 2x 4+4 Pin CPU. To power SATA devices, there are only 8 connectors on 2 cables, and only 2 Molex connectors, which will probably disappear from power supplies altogether in the next couple of years.
Length and number of cables:
- 1x ATX 20+4 - 600 mm
- 2x CPU 4+4 Pin - 700 mm
- 3x PCI-E 6+2 Pin - 500 mm
- 2x SATA (4 connectors) + Molex 4Pin (1 connector) - 500+150+150+150 mm
- 1x 12V-2X6 (1 connector, 600 Wt) - 600 mm
The insulation on the power cables is not smooth, but decorated "like a weave", so if you haven't managed to hide the cables in the case out of sight, then at least they will look somehow unusual, but in general, in this regard, the Ocypus Iota 1200 is ordinary and ordinary. Other manufacturers have taught us that even a power supply can be equipped with something useful, such as Velcro fasteners for laying cables, an ATX24-pin plug for powering on the power supply without a motherboard, a purse for unused cables, or something else – there is nothing like that here, although the power supply belongs to the expensive category.
What's really interesting about the Iota 1200 is its appearance.: here we must pay tribute to the designers, who found some previously unused notes in such an ordinary rectangular design, hiding the bronze fan sleeve behind a dark steel grille. Both off and on, the power supply grille looks very interesting, so if you have a case in which it looks outwards, this is a great option to emphasize the individuality of your build.
The Ocypus logo is also immediately noticeable on the side and will not go unnoticed. Plus, the paint has a rough coating that resembles a Raptor car, which does not leave fingerprints, and the dust is not so noticeable for a long time.
Design features of the power supply unit
The Ocypus Iota 1200 is designed according to a DC-DC conversion scheme with one powerful 12-Volt bus capable of delivering as much as 100 Amperes. The power supply platform looks very simplified, most of the components are soldered on the main board, and only one daughter is responsible for the conversion for +3.3V and +5V buses.
The manufacturer emphasizes that only Japanese capacitors are used in the design of the power supply unit, which is confirmed by autopsy: Nippon Chemicon smoothing capacitors, the rest are Rubicon and Polycap.
The standard filter kit is soldered at the input: X- and Y-capacitors, chokes and a varistor.
Hong Hua's 120mm HA1225H12F-Z fan is responsible for cooling, and if you've been closely following the power supply reviews over the past few years, you've seen that these fans are installed in all "above average" and even top-end PSUs.
Externally, the fan looks very impressive due to the translucent central cover covering the sleeve. The fan can operate in normal mode or in "Eco" mode, when the power supply is satisfied with passive cooling at a load of up to 50%, and the blades do not rotate. The maximum speed is reached at 100% load and is 2200RPM.
Testing
When testing, the first thing we do is check the output of busbar voltages beyond the nominal value at various loads. Looking at the test results, you are surprised at the voltage stability under various loads, and the deviation from the nominal value is about 1-2%.
In terms of efficiency, we see a pronounced "hump" in the range of 200-500 Watts with a consistent slide to nominal.
The main bus voltage of +12V is stable throughout the entire measured range, deviations are minimal and are below the permissible limits.
Conclusions
In terms of basic performance, the Ocypus Iota 1200 power supply is not inferior to its more expensive counterparts, which is not surprising today. In terms of design features, this model does not stand out in any particular way, there are no obvious advantages or disadvantages, and only the design of the Iota 1200 is somewhat different from the others. In general, if, according to the statistics of sellers on marketplaces, the number of refunds is minimal, this model can be safely taken as a cheaper alternative to DeepCool or Zalman.
