Cybenetics Efficiency
Cybenetics Efficiency is a power supply unit (PSU) energy efficiency certification system that serves as an alternative to the 80 PLUS standard. It is more accurate as it considers efficiency at various load levels (10%, 20%, 50%, 100%) and at different input voltages (115V, 230V). The labeling of this system is identical to 80 PLUS:
Bronze — overall efficiency from 82% to 85% at 115V input voltage and from 84% to 87% at 230V;
Silver — 85 – 87% and 87 – 89% respectively;
Gold — from 87% to 89% (115V) and from 89% to 91% (230V);
Platinum — 89 – 91% at 115V and 91 – 93% at 230V;
Titanium — 91 – 93% (115V) and 93 – 95% (230V);
Diamond — ≥ 93/95%.
Cybenetics Noise
The Cybenetics Lambda certification system evaluates the noise level of power supplies (PSU), providing consumers with information about their acoustic characteristics. As a result, you can rely not only on the efficiency of the power supply but also on its noisiness. There are the following Cybenetics Lambda certification levels:
Standard — from 40 dB(A) to 45 dB(A) – noticeable noise;
Standard+ — from 35 dB(A) to 40 dB(A) – distinct noise;
Standard++ — from 30 dB(A) to 35 dB(A) – moderate noise;
A- — from 25 dB(A) to 30 dB(A) – moderately quiet;
A — from 20 dB(A) to 25 dB(A) – quiet;
A+ — from 15 dB(A) to 20 dB(A) – very quiet;
A++ — less than 15 dB(A) – virtually silent.
ATX12V version
A standard for power supplies that supplements the ATX specifications regarding power supply along the 12 V line. Introduced into use since the time of the Intel Pentium 4 processor. In the first series of the standard, the +5 V line was mainly used; from version 2.0, the +12 V line was introduced to fully power the components computer. Also in the second generation, a 24-pin power connector appeared, used in most modern motherboards.
MOLEX
The number of Molex (IDE) connectors provided in the design of the power supply.
Initially, such a connector was intended to power peripherals for the IDE interface, primarily hard drives. And although the IDE itself is completely obsolete today and is not used in new components, however, the Molex power connector continues to be installed in power supplies, and almost without fail. Almost any modern PSU has at least
1 – 2 of these connectors, and in high-end models this number can be
7 or more. This situation is due to the fact that Molex IDE is a fairly universal standard, and with the help of the simplest adapters, components with a different power interface can be powered from it. For example, there are Molex - SATA adapters for drives, Molex - 6 pin for video cards, etc.
PCI-E 16pin
the 16-pin PCI-E power connector is designed to replace the existing 8-pin counterparts. It consists of twelve lines for current supply and four more for data transmission. The connector provides up to 600 W of additional power, which is a fourfold increase in power compared to 8-pin versions of the interface. Additional PCI-E connectors of all formats are used to power those types of internal peripherals that are no longer enough with 75 W supplied directly through the PCI-E socket on the motherboard.
Floppy
The presence of at least one Floppy power connector in the PSU.
Initially, this connector was intended to power floppy disk drives, hence the name. It is also known under the designation "mini-Molex". Anyway, this standard is generally considered obsolete, but it is still used by some specific types of components, and therefore continues to be used in power supplies.
+12V1
The maximum current that the PSU is capable of delivering to the first power line is + 12V.
For more information about power lines in general, see "+3.3V". Here it is worth mentioning that 12 V is the most popular voltage among computer power connectors. It is used in almost all such connectors (with a few exceptions), and some plugs (for example, additional PCI-E power for 6 or 8 connectors) use only 12-volt lines — and in the + 12V format. And the division of + 12V power into several separate lines is used for safety purposes — in order to reduce the current flowing through each individual wire, and thus prevent excessive load and overheating of the wiring. However, some manufacturers do not specify the maximum current for individual + 12V lines and give only a general value in the characteristics; in such cases, this number is indicated in this paragraph.
+5Vsb
The maximum current that the PSU is capable of issuing + 5Vsb to the power line.
For more information about power lines in general, see "+3.3V". Specifically, the + 5Vsb line is used to power the computer electronics in standby mode, when the main and only task of the system is to respond to pressing the power button. This does not require high power, so this figure rarely exceeds 3A.
+12V
The maximum power that the PSU is capable of delivering to the + 12V power line.
See "Maximum current and power" for details on power lines in general. Here it is worth mentioning that 12 V is the most popular voltage among computer power connectors. It is used in almost all such connectors (with a few exceptions), and some plugs (for example, additional PCI-E power for 6 or 8 connectors) use only 12-volt lines — and in the + 12V format. So this indicator is one of the most important characteristics of any PSU.
Note that many power supplies have several separate + 12V power lines. In such cases, the total power is indicated here, which, usually, is divided equally between the lines.
