The First Take on Versa N23 Chassis from Thermaltake

Thermaltake PC cases have never been a frustration. The Versa N23 is not an exception. It is a combination of functionality balanced with modern styling and a bit of company’s passion. The middle-tower chassis draws attention by the front panel with light-blue insertions against black panel. The other attraction is the right-side panel with an integrated acrylic window.

Thermaltake Versa N23 is intended to accommodate mini-ITX, micro-ATX and ATX motherboards with the maximum of 7 expansion slots. The availability of ODD bays enables the installation of two 5.25-inch drives. The layout also welcomes five 3.5-/2.5-inch drives which might be mounted without any tools.

Internal space is enough for 160-mm high CPU coolers, PS/2 ATX power supply units and 250-mm long graphics cards. If retrieving unnecessary drive bays from the bottom section, there is a chance to install 360-mm long videocards.

To continue, air cooling configuration offers 5 seats for 120 mm fans (2x …

Modular Power Supply 650W Chieftec A80

Evaluating the effectiveness of modern computer power supplies, the most attention is paid to their coefficient of performance (COP) at a given load — usually means of 20%, 50% and 100%. At the same time, not less important requirement, established by standard 80PLUS should be considered. That means — the preservation of this level of performance for all occurring in the world supply voltage variations, that is in the range of 100-240 V.

The standard rules of 80PLUS at different levels (Basic, Bronze, Silver, Gold, Platinum, etc.) are performed for two voltage 115 V and 230 V. In both cases, the normalized PS should show the efficiency of not less than specified for each category level. Not usual power supply CTG-650C model of the new A-80 series from the Chieftec company is interesting in that it has officially claimed efficiency of 85% or more, but only for nets 220-240 V.

As the advantages of such solution can immediately be noted a lower price, due to less stringent …

PSU Enermax Revolution87+ 750W Review

This year has become rather successful for Enermax, a well-known manufacturer of power supply units. The company supplemented its product lines with six series combined into four major groups: entry-level, athlete, royal, and gold class. Revolution87+ series belongs to the Gold Class group and involves five models (from 550W to 1000W power). Model Revolution87+ 750W is distinguished not only by the availability of 80Plus Gold certificate, but also by an original branded platform developed by Enermax specifically for this series.


Enermax has implemented a few striking technical solutions in its Revolution87+ 750W power supply unit. The first attractive feature is a composite control over the main inverter. The control is realized by traditional pulse-width modulation method, as well as by simultaneous involvement of pulse-frequency modulation (the combination of width and frequency in control process).

Upon the whole, this PSU model is able to demonstrate up …
