Question:

How do I select the power supply for the desktop? Is it good for 350W or good for 500W?

How about the power and game Huntkey? Compared with the prices of power players, better quality and stability of who? Please follow the high school low-end analysis, please do not copy paste from the network, the original answer is best!!!

Answer:

Huntkey and Titans game with the price ratio, like Volkswagen Huntkey, game players like Chery, but with the price if you want quality or performance, the same price Huntkey 350W Titans game 500W
If installed a rated: 500W power supply, is relatively stable, better heat dissipation, relatively quiet, such as Tt, KK600P powerful version, 80PLUS, power saving than ordinary power, because the conversion power is large. If the chassis can be installed fans, it is best to install a fan before and after each case. Make a ventilation channel.Your estimate has no problem, the whole machine consumes about 320~330W at full load, redundancy 30%, 420W~450W power supply is more suitable. When your computer is working normally, the power consumption is about 200~220W, and the conversion efficiency is the highest for the typical power load of about 50%. If 500W power is used, most of the computer work at 40% load, belonging to a slightly lighter load, the conversion efficiency is not as high as typical load, so the power use 420~450W power, the most energy-efficient. However, 500W is also good, because the power load is relatively small, so the noise of the fan is relatively small.
Look at the full load power consumption of the whole machine. How much is the normal use of the budget power supply? 6.70% is more reasonableThe whole machine is 200W, then 350W power is reasonable, full load 300W up and down, then power 500W is more reasonable!
The power of the power supply according to your needs and your hardware configuration, can not be generalized, you know?If your CPU, graphics card, these power consumption is high, the general choice of 500W or so, generally more gamersIf your CPU, graphics card itself power is relatively low, or there is no independent graphics card, then 300W is enough, and generally more domestic type.
(1) how much power the desktop chooses, which should be judged by the level of the configuration, especially the power supply of the video card.(2) if the office based, and integrated graphics card, there is a 200W power enough.(3) if the game is based, CPU or I3 I5 or more, so the power will be based on graphics cards:In general, if the graphics card is an entry-level video card, such as GT 730, 300-350W is enough. Is the mainstream graphics, such as GTX750TI in 400W, the general level is fancier graphics, GTX660 generally have 450 500W or so, if it is the top game player, such as the GALAXY GeForce GTX Titan X 12G to 600W.
