Premium Chieftec Navitas 650 W PSU Review

Announced several months ago, Chieftec Navitas series of PSUs has managed to win the hearts of PC enthusiasts in many areas across the globe. Unlike the majority lineups where the junior model features 450/550 W power, Navitas offers 650 W GPM-650C as the first model in the line to satisfy the needs of fastidious customers. Upon the whole, the series counts five models of 650 W, 750 W, 850 W, 1000 W, and 1250 W power. Let’s see whether the junior representative of the series deserves universal acclaim.



Basic Specs and Connectors


Chieftec Navitas 650 W is delivered in a gray cardbox that contains its basic specifications. The unit is able to gain up to 648 W power on +12VDC rail efficiency. The correlation of efficiency on +12VDC rail and an overall power makes up 0.997 points. The model itself is housed in a gray case with large texture coating. Its layout might boast the incorporation of a high-voltage Nippon Chemi-Con capacitor and as much as efficient Capxon …

Computer Case be quiet! Silent Base 600 Overview (Part II)

Internal structure

The motherboard compartment is located above the power supply unit. In this regard, everything is quite standard for a Mid Tower class. A large cutout is made in a tray behind a CPU socket, to allow installation of a CPU cooling system directly into the case; a backplate mount (thrust-pad located on the back side of the motherboard) is used for this purpose.


The four large slots in a tray, equipped with the silicone membrane, are designed for proper cable management which looks very promising here. Plugs of expansion slots are attached by thumbscrews. The front part holds a hard disks’ basket for three drives.


At the back side a slot in a tray can be clearly seen to access cable management system slot. Also, the rear side contains two tool kits for installation of solid-state drives and size 2.5" hard disks.


The side cover is made of 0.7 mm steel, and from the inside has a thick vibration and noise absorbing coating. The recess in the …

AMD FX-8300 is Already in Retail Trade

Despite the fact that AMD initially scheduled the official release of FX-8300 for 29 December, this CPU can already be found in some Japanese retail stores. Such sudden appearance in free sale allows all potential consumers to get assured in all claimed specifications. Thus, FX-8300 is an eight-core chip of the new generation that is characterized by 95W TDP level. This is a kind of a breakthrough, since its Vishera companions, FX-8350 and FX-8320, consume up to 125W power.



The reduction of power consumption is explained by the decrease of CPU clock frequencies and nominal voltage showings. Hence, the nominal clock frequency recorded with this CPU model makes up 3.3GHz, while in Turbo mode the frequency rises to 3.6GHz. Some resources state that FX-8300 is able to overclock up to 4.2GHz, however, this info is not vindicated so far. This chip is developed specifically for Socket AM3+.


Taking into account such parameters, analysts feel difficulty in predicting the future of …
