As the title says, I'm in the market to purchase a new power supply. Now some specs on the system. The computer is a store bought good ole' eMachines. About a week, and a half ago there was a storm, and my psu blew. So I swapped it with another one that I had, and the computer came back to life! Now here's the questions... - I shop from newegg.com, and I see there are either several types. ATX12V, ATX12/EPS12V, AT, MicroATX, I know these are the form factors, but I'm not sure what mine is.. Pin Types: 20, 20+4, and 24. I disconnected the psu from the mobo, and counted 20 pins, and one is not there? like not broken off, but skipped? - I open the case, and look on the psu, and it only has input/output voltage, frequency, manufacturer, and the s/n. The voltage of the current one is a max of 280. The old one that was in it, was 300. Now the reason that I need to change it, is when I leave the computer alone for a few minutes, it powers down. I have every setting that I know of disabled for that type of feature. I need help.
hello. atx and micro atx are todays standar in psu the size 300w,400w etc depends on you system needs what kind of procesor your pc have how many drives(cd-rom,hard drives etc..) any case fans?. atx 12v comes in 20 pins and eps12v 24 pins if says boths it means it comes with a 20 pins an 4 pins extra for the main connector in case need it. but you can buy a 450w or 480w psu dont go for generic psu they sometimes dont output what they suppose to. http://www.newegg.com/Product/Product.asp?Item=N82E16817153022 this one is very good psu great output and comes with 20 pins and the four pin adapter.
