I have an Antec P182 and I need to upgrade the power supply. I originally built the system in 2007 and it used a smaller power supply. Is there any manufacturer that makes at least a 750w power supply that will fit in this case?
Lots of them...The P182 fits a standard ATX PSU. The only thing that I would worry about is the length
of the PSU; longer PSUs make it more difficult to route behind the mobo because of the cutout placement. What are your system specs? If you're not doing SLI/CF it would be hard to see how you need that much juice...
Edit: Another thing you need to look at in your PSU purchase is the length of the PSU cables. I have a P183 and a Seasonic M12II-520W...I have to use a 4-pin extension cable to reach the socket on the mobo. Same situation with a OCZ ModXStream 500W that I had in it at one time.
