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 …

Gigabyte Intros Micro-ATX Motherboards on Intel H81 Express Chipset

Gigabyte Technology introduces three new motherboards of micro-ATX form-factor, based on Intel H81 Express chipset. The new-comers, entitled GA-H81M-DS2, GA-H81M-D3V and GA-H81M-D2V, are equipped with LGA1150 socket that supports Intel Haswell CPUs. Their efficiency and durability is the result of the implementation of Gigabyte Ultra Durable 4 Plus concept, On/Off Charge and UEFI DualBIOS technologies, as well as of prime capacitors with a solid electrolyte. Each motherboard is unique, so the specifications of each item are worth of being detailed.

Gigabyte GA-H81M-DS2 features:

— 226 x 170 mm dimensions;

— the possibility of integrating up to 16 GB of two-channel DDR3 memory with up to 1600 MHz frequency;

— a pair of SATA II and SATA III ports;

— a pair of PCI Express x1 slots and a single PCI Express x16 slot;

— gigabit Ethernet port;

— Realtek ALC887 controller with the support of HD Audio sounding;

— rear I/O panel with RJ-45 port, D-Sub, …

Aerocool Updates Several Mainstream PSU Lineups

Aerocool expands its mainstream- and budget-oriented PSU lineups with a batch of new models. Notably, it replenishes such series as VP, VX, and KCAS to satisfy the needs of a wider public. Without doubt, all greenhorns absolutely comply with the company’s best practices implemented within design and performance frameworks.

Hence, Aerocool VP, the most affordable series in the inventory, has been refilled with three models of 850 W, 1000 W and 1200 W power. They are distinguished by the integration of a single +12V rail, support for the Intel Haswell platform, and compliance with C6 and C7 idle states. All units are estimated for 120 thousand hours of foolproof operation, providing up to 84% efficiency in a wide range of workload. Their other peculiar feature is absence of 80Plus certification.

The VX series has been replenished with two low-power PSUs of 400 W and 500 W power. Their ultimate power on +12V rails makes up 324 W and 456 W correspondingly. Both models are …
