Chieftec Showcases Five New PSUs from Navitas Series

Chieftec, one of the largest German hardware manufacturers, has recently introduced a new series of power supply units, codenamed Navitas. The series is represented by 5 models: GPM-650C with 650W nominal power, GPM-750C with 750W nominal power, GPM-850C with 850W nominal power, GPM-1000C with 1000W nominal power, and GPM-1250C with 1250W nominal power correspondingly. All the products have won 80Plus Gold certificate, due to more than 90% efficiency in the high workloads.

Chieftec Navitas PSUs correspond to ATX12V v2.3 standard and support Intel Core 4th gen. processors that require little current strength on +12V rail in sleep mode. The models also support active power-factor correction option to provide for the maximal stability during operation. They are equipped with a composite cable system and a single +12V rail, estimated for the maximal current from 54 A to 104 A (this index depends on the unit’s power).

All five units are cooled down by 140 mm fans with PWM …

Dell Teases a Couple of IPS Monitors: P2417H & P2717H

Dell is about to launch a pair of monitors targeting office PC systems as well as standard home multimedia systems. The P2417H (24-inch display) and the P2717H (27-inch display) are fitted with a high-quality IPS panel with an integrated LED backlight. Both models feature 16:9 aspect ratio and Full HD resolution – 1920x1080 pixels.

The implemented array offers 6 ms response time in GtG environment. The top brightness index makes up 250 & 300 cd/m2 respectively. Both new-comers share the widest possible viewing angles (178/178 degrees) and are able to display up to 16.7 million colors. Static contract index equals to 1000:1, whereas dynamic ratio approximates 4M:1.

Dell P2417H and Dell P2717H boast a rich inventory of external interfaces: a pair of USB 2.0 ports, the same number of USB 3.0 ports, one DisplayPort 1.2, one HDMI 1.4 port, and one analogue D-Sub port. The first display is thought to consume 19 W power, while its companion is known to consume 23 W power.

Zotac GeForce 640 GT: Kepler for $ 100

The emergence of a new GPU architecture does not only make records in the performance of high-end graphics cards, but often changes the idea of what to expect from an inexpensive card with a low TDP. Let see what can offer GT 640 — associate member of the family Kepler

The lower segment of the GeForce 600 is already fully staffed. In retail, there are cards GT 610, GT 620, GT 630 and GT 640, and in the OEM- channels additionally supplied GeForce 605. But among all of them, only GT 640 can be called a fully new model, since it is based on the architecture of Kepler, and the remaining cards are a familiar model series GeForce 400 and GeForce 500 Architecture (Fermi) with certain minor modifications.

GeForce 640 is based on the GK107 chip, which previously debuted in accelerators GeForce 640M. The performance of the last was comprehensively studied on the laptop Acer Aspire M3-581TG: compared to the GeForce 540M new chip provides a very nice speed boost. GK107 contains one …
