Method/Step

Determine the power required for the power supply. The desktop of the major hardware (CPU, motherboard, graphics, memory, hard disk (SSD)) TDP (TDP for thermal power consumption, not equal to power consumption, may be the actual power consumption can also be used as a reference) added up to see the total number of high-power. General hardware shows how much the maximum TDP is. CPU and graphics card is generally a few large power consumption, the two powers to set down, the other difference is not big. These two a certain, basically can determine how much power. The selected power supply needs to be larger than the TDP power. such as TDP is the largest 300W, the best choice of 350W power supply.

In general, the integrated graphics power supply 250w-300w The rated power is sufficient. Medium and low-end graphics cards, rated 300w-400w, high-end graphics cards in the rated 500W or more. If the gtx750ti power is small, the quota is fixed 350W power can, GTX660 then need to be rated 400W above power supply.

Overclocking players need to consider the power supply more, to see the degree of personal fever and hardware overclocking after the power consumption, increase power supply. such as i5 4670K CPU with GTX760 graphics card, the power of the best in the rated 500W or more.

Determine the power supply dimensions. This is mainly to consider the compatibility with the chassis problem, the general large chassis does not fit the problem. If it is a small machine, you need to pay attention to the size of the power supply to see if it can be installed. Generally speaking, the low-end power supply can be well installed in the small chassis inside.

PFC (the phase difference between current and voltage will result in loss of switching power) power, PFC is divided into active and passive. Active PFC is more energy-efficient, so it must be selected for PFC. Now the brand power is basically active Pfc.

Thermal design and wire. Pay attention to look at the power supply cooling design and the use of wire, simply to power supply weight to measure the quality of power is not scientific. Before buying a power supply, suggest that you understand the information on the Internet before you begin.

Select 80plus (bronze, silver, gold) on demand. In fact, 80plus is only a power conversion efficiency of a certification standard (copper, silver, gold conversion efficiency in turn to improve), more energy saving, and power quality is not directly related. The conversion efficiency without certification is not necessarily low. If the fund is abundant, can choose 80plus attestation, because pass attestation of thing after all many safeguard.

Modular wire Management. Modular wire management, users can be based on their own needs wiring, the chassis will not have redundant lines. If one of the lines damaged, you can go directly to the wire market bought to change. Of course, module power than non-modular power is much more expensive, like overclocking, conditional friends best with the module power supply.

Power brand. If you don't know a lot about the power supply. The best choice of power supply brand, the Great Wall, aviation Jia, titanium, etc. are a good choice. If the request is higher, you can choose pirate ship, Bone gamma, sea rhyme and other brands. Especially overclocking players, good power is particularly important.
