Right now i just started to learn the basics of pc hardware.
i have some doubts if any can clear it then it is more helpful for me
its all about pc power supply
1.In a single phase connection voltage is constant.in our country it is about 230v.
it provide max 40 Ampere.
there are 2 types of socket.
5 amp and 15 amp socket
Device that connect to a 5amp socket maximum draw 5amp.it cant use more than 5 amp.
am i right?
2.I use 800 watt powersupply in my pc.
Power=voltage*current
P=v*i
800w=230*i
i=800/230=3.4 amp
so my powersupply maximum use 3.4amp.
am i right?
3.so smps convert this ac voltage into appropriate dc voltage to use different pc component
I dont know dc voltages used by every connector
mainly there are 5 connectors
atx 20 pin connector
Eps 12v 4 pin or 8 pin connector
pci e 6 pin or 8 pin connector
molex connector
sata power connector
can you give me the voltage,ampere used by this connectors.
so i can calculate max wattage provided by every connectors
4.why iam asking this questions because i got information about the wattage of 8 pin EPS +12 volt power cable like this from some website
here 12v connector uses 28 amp which provide 336 watts
in my views 800 watt psu max draw 3.4 amp from socket
then how it use 28 amp for this connectors?
if you say smps can draw more ampere than 3.4 amp then how it draw more than that when it connected to a 5 amp socket which only provide 5 amp maximum?
