Nothing in instructions mentions connecting these at all.Not sure what the problem could be, any ideas ?thanks
Do yourself a favor and please pick up a name brand PSU like a Corsair / Enermax, PC&P, seasonic Power supply in the 550W range for that 7870 .
If you try to use that cheap power supply from HP, its not going to work. The case will probably be fine(assuming it fits) , and the card should run fine as well, with a proper PSU.
