Hey All, I recently purchased a HP 6300 Pro minitower (BTX SFF) that has a 320W PSU. I would like to put in a better and more powerful PSU to drive a nVidia GTX 650 graphics card and other peripherals. However, this appears to be an interesting problem:

1) The size of the OEM PSU is different than regular ATX PSUs. The connectors are also different. There is no 20/24pin main 12V cable. There are only 3 - an inline 6 pin, 4-pin, and 6-pin, all which connect to the motherboard. Here is an image of what the board looks like: http://www.aliexpress.com/item/Free...239-001-656961-001-chipset-Q75/906004623.html

Q1: Is there a compatible PSU out there somewhere?

Q2: Is there a way to split (via a connector) the 4-pin (I am guessing 12V) main power to the motherboard to a 6-pin PCIe to power the GFX card?
