  1. Um well i would need to know your graphics card to be 100% sure.
    But sounds like yes it will fit in your motherboards PCI-E Slot.

    But from what cards are coming to my mind, your 300watt PSU will not be enough to power the card, atleast not safely.
  2. what card and what power supply, the slot is unimportant as they are both pci-e (cards are generally x16)
  3. i have just updated my messaege sorry new to this thanks
  4. Yes, i would say go get a new 400watt Powersupply or greater.

    It is very risky to go under the cards recommended powersupply requirements, since it could wreck your motherboard which is connected to everything else.

    400 watt power supply's can be bought for very cheap.

  6. Nope just unplug all the cords, buy the new PSU and then reconnect the cords into the desired spots.
