    Hey Ashiekh thanks for your reply, i am not going to do anything with the fujitsu psu, as far i understood i can run my builts beside the asus with the builtin psu. Am i wrong? I am really confused. Thanks

    So long as you don't go wild on the video card

    The GTX 950 is over 200 W and the GTX 960 a little more, so you probably need more power (400 ~ 450W)

    Whole System!
    The 950 has an official "TBP" of 90W, the 960 is a bit more but far from what you said...

    Whole system, yes.

    True

    https://www.guru3d.com/articles-page...-review,7.html

    and that is on an i7

    However they still recommend

    "
    GeForce GTX 960 - On your average system the card requires you to have a 400 ~ 450 Watt power supply unit.

    One of the reasons you shouldn't go to Guru3D for PSU reviews.

    Good point, but how is one going to power the video card? there are no connectors for the video card.

    You can unscrew the case, and solder wires where the 12v and ground wires are ... or just splice them to exising 12v and ground wires.

    Here's an example adapter cable you can buy for 3.5$ : https://www.newegg.com/p/N82E16812198018

    You can cut the female pci-e 6 pin connector and solder the wires inside the psu.

    The psu in the picture above claims it can do 250w on 12v continuously, so running a card that consumes up to 100w or so should be doable, if combined with a low power cpu.

    The systems in the first post should not consume more than 100w without the video card, so you could use a rx 470 or something that draws just a bit of power from the additional pci-e 6pin connector (rx 460 , rx 560 , gtx 950 , gtx 960, gtx 1050..1060, etc)

    The best would probably be GT 1650 at less than 75w (no pci-e 6pin required), followed by RX 470 (at around 100-120w, which may be a bit too much for a 250w psu), then a GT 1050 / GT 1050 ti and then RX 460.

    Considering you can buy RX 470 cards on eBay for around 70$ it would be worth trying. Worse case scenario, you can play with the power budgets in the driver.
    You could even download the bios (using AtiWinFlash, windows software), edit it using SRBPolaris to change the maximum frequencies to artificially limit the video card to lower frequencies and therefore lower power consumption and then program the new bios.

    Or off the hard drive power cable to avoid soldering or splicing. I have a PC with 12V power supply and the hard drive power cable plugs into the mother board.

    But I think you are right, a video card that does not need supplementary power is best.
