How does a ATX case differ from a Micro ATX case?
I have a HP Pavilion model 7955 and it’s a small tower (only 14.5" high).
Today the techie on “HP Live Chat” told me I have an ATX case, not a micro ATX. But for some reason I had in my mind that I had a Micro ATX because of it’s size. So I’m confused as usual and need your help to set me straight.
The reason I’m asking is I want to upgrade my little 200 watt power supply (Bestec ATX 1956D) to at least 300 or 350 watts.
My current Bestec PSU measures 5.9" W x 3.4" H x 3.9" Deep and that sucker is so tight in the case I need to get an exact “same size” replacement…or it just won’t fit in my case. No foolin…anything bigger will not fit.
What’s a good brand of PSU? Who sells them for a good price on line?
Do all PSU’s have the same output voltages and amps?
Do all mobo’s require the same voltages/amps? If not, how will I determine what I need?
Besides fit…what should I look for in a new PSU?
I need a little help from my friends…
Thanks guys…and yes I’m still screwing around with this 4+ year old HP.
