Hello again, folks. I want to order a new psu for the computer that I'm upgrading, but I know nothing about power supplies in general. I am upgrading a Compaq computer and the unit that's in it is only 220W. I need to know what I need in a new one. As far as "type" goes, it was suggested in another thread that I would get ATX, but what about main connector pins(20 pin/20+4pin)? Dual +12v? PFC? Newegg has all these categories.Thanks for any help you can give.

Also: What manufacturers would you recommend? I was leaning towards a Thermaltake or a COOLMAX.

I posted this on another forum as well, so if you see it out there, it's me.

it would have to be a micro ATX PSU looking at the case... but a standard Matx one should work

Man, I hope not. I can't find any psu's at 400W or over when searching for Micro ATX units.
 
open up the case and look at the PSU you have there... do a search for it and see what the specs say if it sayd matx/micro atx etc then you have that to look forward too...

if your just looking to replace the one you have a 350 should work nicely and still give you the room to upgrade... as long as your not getting a high end video card, you should be good...
 
Okay, I searched and I think this is my psu:

This is the sticker info that I got straight from my actual one:

-12V / .15A
+5VSB / 3A
+12.8V / 7.5A
TOTAL OUTPUT POWER
220W 220W
E131881

Looks like he same one eh? Is it just ATX and not Micro? By the way, here are the physical dimensions. I measured it myself:

5.5 inches wide x 4 inches thick x 6 inches long. There is about 2 inches of clearance from the front of the unit to the dvd drive and about 1 inch from the bottom of the unit to a cooling fan.


Thoughts? Recommendations?
 
So, as long as the dimensions fit, I just have to make sure that the psu I buy is ATX? Is there anything else that I need to take into consideration?
