PSU

what info are they?

how good is your physics. So the first row is the different voltages your power supply outputs to power your pc. The second row is the maximum current each voltage(often called rails) measured in amps. The third row is the max power output each rail can output (VxI=P where v is voltage i is current and p is wattage). Adding the thrid row up gives the max total output

This is a table of all the voltages the PSU can output and the amperages it can provide at each voltage. You should learn about PSU rails to understand it more thoroughly, but the power supply has several smaller powersupplies in it. One produces 3.3V, one 5V, one 12V and so on. You can only stress each of those to a degree until it overheats and dies. And those maximum values are given here. One key piece of information is omitted. For this info to be valuable, you'd need to know at what temperature these values can be achieved. But basically V = Volts, A = Amperes and W = Watts (Volts*Amperes)

 

Also you should know that this is exactly where cheap PSU manufactures lie through their teeth. The fact that this has a bunch of Chinese on it tells me, it probably can't get even close to those values.

Thanks ,but i want to know +12V > 41A > 492W For what types of connection?is it for GPU?

[astrosheen]

both gpu and cpu

Most components in your PC are connected to the 12V rail. So the GPU and CPU should be drawing from the 12V rail.

Ah! It's everything that uses +12V. Or for witch the operating voltage is derived from the +12V rail. CPU, GPU and a lot of components on the motherboard like the chipset. Fans, the motors on the HDDs and the ODDs and so on. the single rail is split between all of them. Stuff that uses direct 5V isn't included such as the USB connectors, the heads on the HDDs and ODDs, SSDs entirely. Other chips on the motherboard such as the audio chip, the network interface chips and so on can use the direct 3.3V rail. Anything that use a lot of power is taken from the +12V rail. It's easier and cheaper to get high amperage at low and precise voltage by regulating from high voltage.
