The First Glance at MSI X99S Gaming 9 ACK & Z97 Gaming 9 ACK Mainboards

MSI could not resist the temptation to officially introduce a pair of new gaming mainboards: the X99S Gaming 9 ACK and the Z97 Gaming 9 ACK. The key distinction of new-comers from analogue models without ‘ACK’ attribute lies in the implementation of dedicated gaming network controllers: Qualcomm Atheros Killer 1525 and Killer E2205. The first one is supposed to support 802.11 ac standard that guarantees 867 Mb/sec throughput bandwidth; it also ensures less data deference. This provides for a faster network traffic processing and, as a result, — for a huge advantage in online gaming.

The E-ATX MSI X99S Gaming 9 ACK motherboard is based on Intel X99 chipset, estimated for Intel Core i7-5000 CPUs with Socket LGA2011-v3. The model features 8x DIMM slots for DDR4-333 MHz memory (4-channel operational mode) of up to 128 GB capacity. Storage subsystem offers eight SATA III ports, whereas expansion facilities are ensured by means of five PCI Express 3.0 x16 slots. The list of …

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 …

SilverStone Debuts with SST-ST30SF Power Supply

SilverStone Technology has recently introduced its newest SFX power supply unit. Codenamed SST-ST30SF, it features 125x100x63.5 mm dimensions and weighs 800 g only. The unit is estimated for 300 W power and is capable to demonstrate more than 81% efficiency in 230 V networks. High efficiency level allowed the model to gain 80Plus Bronze certificate.

The most uncommon feature ascribed to SST-ST30SF is that it can operate in passive mode if thermal conditions allow. The unit is equipped with a fan of 80 mm dimensional type; it starts rotating only when the surrounding temperature reaches 55 degrees. This promotes for a considerable power reduction and practically silent work when the fan gets disabled. An average noise level on active operation makes up 18 dB.

SilverStone furnishes the new entry with a single +12V rail, estimated for 22 A current. In its turn, +3.3V rail is estimated for 21 A current, while +5V rail – for 20 A current. It should be noted that this unit …
