Can You Replace a Dell Mini Tower PSU With a Standard ATX PSU? Tags: Power Supplies Dell ATX Components Last response: November 6, 2012 4:53 PM in Components Share Somelikeitsmooth November 6, 2012 4:12:14 PM Hello again everyone. I'm trying to upgrade my Dell Optiplex 960 mini tower. I want to put a NVIDIA GTX 560 or similar into it, but my PSU is only rated at 255W. I've been looking everywhere for the answer to this and I can't find it online or in these forums, so I'm starting a new thread. Does anyone know if I can use a standard ATX power supply from Newegg or the like? I've read that some Dell units use Mini PS3 or BTX power supplies (I'm not really sure what that means, though. Thanks in advance. More about : replace dell mini tower psu standard atx psu Somelikeitsmooth November 6, 2012 4:53:01 PM This eBay store guarantees that this power supply will work. I'm not interested in this power supply in particular because there's no brand name on it, but it looks like a standard ATX to me.
