I would like to use a decent graphics card for moderate gaming (medium settings) in my
HP Pro G2 MT Desktop PC 6XB14EA#ABD Intel Core i5-8500
For that I would at least need a 300W power supply unit.
But I cannot find a fitting psu because the standard atx connectors of most psu's do not fit the mainboard of my Hewlett-Packard PC.
There are adaptors for atx 24-pins main power plugs to Hew-Pack 6 pins available, which also do something to the current of the green and gray atx-standard wires.
Assuming an ATX standard color coding: I'm all good with powering the cpu and the mainboard supply, both with 4-pin 12V+ DC wire pairs (Black and Yellow cords).
But then there is that ominous 7-Pin "PWRCMD" (Power Command) connector, which (in my case) features only a green and a black wire. - According to atx color coding this would mean "ground" and a "power supply on"-signal (which would be somehow 'boosted' to 12V by those chinese adaptors). Does this go for my mainboard too? In that case I could use ATX standard pin 16 (power supply on - signal), could I not?
So simply wire yellow to yellow, black to black and green to green...
i don't mean to be rude, but people like you simply have to stop buying/acquiring non standard equipment/small form factor systems and then trying to make them a gaming rig............ NOT GOING TO HAPPEN
you want a gaming system? then buy a prebuilt system that uses industry standard parts instead of custom designs or build one using ATX compatible parts
small form factor systems are simply not designed to work with high wattage video cards, and the same goes for systems using custom parts/cases the upgrade path will be either very limited or non existent
your HP G2 Pro Mini tower system is targeted to light office, media server or home theater scenarios not the gaming market the listed low profile video cards that HP lists are all 50 watt draw or less
