I am trying to upgrade power supply from the stock 750w or 1000w power supply for 3000 po3-630

I am trying to upgrade my power supply from the stock 500w to a 750w or 1000w so I can install and new GPU. It seems the board has a unique layout and standard power supplies will not work. Is there a power supply available that will work on a 3000 series board? Is there some sort of adapter that is available?

The PO3-630 uses an ATX12VO power supply, based on the newer standards set by Intel. The 12VO supplies are more efficient and cheaper than traditional supplies because they only deal with one output voltage instead of several. There aren't many choices for third party supplies though, and until recently there were none that provided more than 500W output. Some users have used a custom cabled adapter setup to put higher output traditional supplies on place, only using the +12V from them. For that to work well you have to source a supply that uses a single rail design with a large output.
