How to choose the right power supply for your computer
The normal operation of all components depends on the power supply.
This component, at first glance, does not have a significant impact on overall performance. But a reliable PSU is like a good system administrator in the office: while it works as it should, its work is invisible. Therefore, in order to understand how to choose the right power supply for a computer, you should carefully analyze the characteristics of its (PSU) characteristics and hardware specifications.
Power calculation
How to choose the power supply capacity for a computer
As a rule, the total theoretical power is indicated as the main characteristic of this PC component. This figure is important, but not decisive. Relying only on it, it is impossible to decide which PSU to choose for a PC. A more important parameter is the current strength along the +12 V lines. It is from them that high-performance components (processor, video card) are powered.
OCZ Gaming PSU. The +12 V lines are highlighted in red. With a theoretical total power of 864 W, the practical value is only 680 W.
To calculate the optimal power supply capacity, first multiply the maximum current of each +12 V line by the voltage and add the results. If there is only one +12 V line, the power reserve should be about 20% of the actual consumption of the components. If there are two or more of them, approximately 30% should be subtracted from the total result. The resulting number will indicate the practical power of the PSU along the main line. For additional (+5, +3.3), there is no power shortage, since these lines are used to power more economical components.
Example 1
The block has 1 +12V line with current up to 22A, 12V*22A=264W. Therefore, this PSU can give the CPU and video card no more than 264 watts of energy.
Example 2
The PSU has 3 +12 V lines, 15 A each. (12V*15A)*3=540. Subtract 30% and get about 378 watts.
Power consumption of components
The consumption of each component is usually specified by the manufacturer.
To understand how to choose a power supply for a computer, it is recommended that you carefully study the specifications of the selected hardware.
- The CPU consumes electricity from 50 (budget Core i3) to 250 (AMD flagships) watts. Thanks to the use of a more modern process technology, Intel are more economical. Octa-core Core i7 and next generation Xeon consume 100-150 W, AMD FX — up to 250.
- For video cards, the spread in this parameter is even greater: being at the same level (budget-class gaming video cards), the GeForce GTX 750 Ti and Radeon R7 360 consume 60 and 150 W, respectively. It is worth noting that in the top segment the difference is not so significant: the GTX 980 Ti, and the Radeon R9 Fury consume about 300 watts of power each.
- Traditional 3.5″ hard drives require up to 20-30 watts of power at the time of spin-up, but during operation their consumption drops to 5-10 watts. SSDs look more attractive in this regard: they do not create current surges at startup, and constantly “eat” up to 5 watts of electricity.
- The motherboard and RAM should also be given attention. Together they consume up to 20-50 W on the +12 V line. The rest of the load falls on the +3.3 and +5 V circuits.
- Powerful air cooling system will consume up to 5 W. For «hydraulics» this figure is at about the same level.
Manufacturers indicate the consumption of components on their website. In the illustration — a screenshot from the official resource ark.intel.com
Connectors
Most modern power supplies are equipped with a sufficient number of cables and plugs for all components. In more affordable models, the wiring is connected directly to the board by soldering; in top models, the cords are detachable. To understand which PSU to choose for a computer, you need to calculate the number of cables needed and their shape.
Power supply connectors unified. Every modern PSU comes with (at a minimum) a 24-pin motherboard cable, a 4-pin CPU power cable, a 6-pin video card cable, and Molex and SATA connectors for peripherals and hard drives.
In principle, this is enough to ensure normal nutrition. But in order to reduce the resistance of the wires when transmitting high currents, iron manufacturers increase the number of contacts and wires. For the CPU, 8 pins are used instead of 4, and for video cards — 8 instead of 6. Such connectors are fully compatible (an 8-pin connector can power a video card with 6 pins, a 4-pin plug will supply voltage to a board with an 8-pin socket, etc.). etc.), but it is recommended to take into account and select the appropriate number of contacts.
The main types of power supply connectors
Examples of calculating the power consumption of a PC
As an example, we can assemble an inexpensive gaming computer based on Intel Core i3-6300 (the fastest dual-core processor) and GeForce GTX 750 Ti. Under the system and for games, a 128 GB SSD is installed, for storing content — a 1 TB hard drive. RAM 8 GB. The CPU consumes 51 watts, the GPU 60 watts, the motherboard with RAM up to 30, the SSD needs 2 watts, the hard drive 10 watts.
The total load is about 160 W, or 13 A along the +12 V line. Even budget power supplies supplied with computer cases can handle such hardware.
If you leave all the hardware, but change the processor to an Intel Core i7-6700, and the video card to the Radeon R9 Fury X, the CPU power consumption will increase by only 15 W, but the GPU will “eat” almost 250 W more than the GTX 750ti. 160 W + 15 W + 250 W = 425 W or 35 A on +12 V lines. With a margin of 30%, the total power of 12-volt PSU circuits should be at least 45 A. An example of a suitable PSU is Aerocool KCAS-700W. With a power of 700 W, it is capable of delivering up to 53 A on the +12 V line.

Conclusion
Knowing how to choose a power supply for your PC, you can ensure the smooth functioning of all components, while also saving money. Some models of power supplies belonging to the budget category can be equipped with a high-quality and strong +12 V circuit.
