So, you have seen seven power supply units in this roundup that differ in their wattage and functional features. I want to single out the A.C. Ryan Ryanpower2 and OCZ ModStream units first. They are curious for their detachable cables. That is, you can use only those cables that your devices are actually attached to. Alas, both these units have defects, although different ones. The Ryanpower2 has excellent parameters but its mounting quality could have been better, there is a limited number of cables supplied with it (short IDE cables, and the 24-pin connector for the mainboard is missing), and it cannot power up 3-volt SATA drives. The ModStream, on the contrary, boasts highest manufacturing quality and meticulous design, but its actual parameters are rather mediocre. One might almost wish there were a hybrid of these two units, with the electronics from the Ryanpower2 and the exterior from the ModStream…
The power supply from CoolerMaster doesn’t try to surprise the user with any outstanding innovations save for the measurer of the consumed power. But this is more a decorative element rather than a really useful tool. Otherwise this is a quality, beautiful, handy and quiet power supply that’s going to suit for almost any midrange computer. If your computer has a high-power configuration, take note that CoolerMaster is a bit cunning with respect to the declared load on the +12v outputs – this parameter of the PSU is only comparable to 300W ATX12V 2.0 models.
HEC’s Macropower MP360AR Ver.2 unit is a typical workhorse. It is a rather inexpensive PSU without a shiny case or highlighted fans and wires or any other beautiful but usually useless embellishments, but it proved to have excellent load capacity and good build quality. This PSU will suit well for a powerful office computer or other such applications. If you’re planning to buy it for your home PC, make sure beforehand that its fan isn’t too noisy for you. Also among the PSU’s drawbacks is the availability of only one power connector for SATA drives.
The two units from MGE performed well enough in my tests. They have a very high load capacity and ensure an acceptable stability of the output voltages. Alas, they are not free from blame, either. The fine protective grid on the fans increases the noise from the power supply considerably. The characteristics of the units are close to the ATX12V 2.0 standard, but they are equipped with a 20-pin connector for some reason. Then, I don’t also understand the purpose of the second 80mm fan which adds a lot to the noise. If these defects don’t frighten you, then the PSUs from MGE may be your choice.
The last was the fanless PSU model from Thermaltake. It is a special model for a specific user group: the price of the PSU is high, but its load characteristics are unpretentious. The noise from a high-quality PSU with an ordinary fan is usually not too irritating at small loads, especially considering that the PSU is not the main source of noise in a modern computer. But anyway, if you do want to buy a fanless PSU for a not-very-advanced computer, do consider the PurePower W0029 from Thermaltake.
