Is graphics card compatible with computer (ATI Radeon HD 4770)

Dear Tomshardware,

I wanted to buy a ATI Radeon HD 4770 Graphics card but I'm not sure if my computer is compatible or not.
the requirements for the card are:

-PCI Express® based PC is required with one X16 lane graphics slot available on the motherboard

-450 Watt or greater power supply with one 75W 6-pin PCI Express® power connectors recommended (550 Watt and two 6-pin connectors for ATI CrossFireX™ technology in dual mode)

The motherboard I have is an ASUS M2A-VM HDMI

I don't know how to check whether I have any of the above written requirements, is it possible to know this by knowing some of the system information? if so please answer my question or ask for more computer information if needed

thank you in advantage.

  1. Your motherboard does have a PCI-e x16 slot.

    As for the power supply requirements, you will either need to open up your case an check out the sticker on the side of the PSU, or search it by the model number if you know it.

    The important information is the overall wattage (at least 450W) and the wattage/current on the 12 V rail. as stated about you need at least 75 W on the 12 V rail, which equates to at least 6.25 A on the 12 V rail. The power supply also needs 1 free 6 pin connector to power the video card (or 2 free 4 pin connectors, you video card should come with an adapter)

    The main two factors to consider when trying to match a VGA to a system are the physical port of the MB and the PSU. Although the CPU is also important in terms of creating a speed bottleneck, the main two factors to consider for now are your MB and your Power Supply.
    The mentioned physical port in this case is the PCI Express gate, which for an HD 4770 is the PCIe 1.0 or 2.0
    For Such a graphic card to perform flawlessly you also need a 500 Watt power supply from a reputable manufacturer.

    - MotherBoard:
    Detail information about your MB can be found here:

    - Power Supply Unit:
    An extensive list and a useful article about good PSU manufacturers can be viewed here:
    to get an estimation for the power requirements of your system you might want to use the "eXtreme Power Supply Calculator" which is a fantastic utility is found

    You should be able to make up your mind using the information here. The only other thing you have to check on your system is the existing Power Supply Unit's output limit

    Msg me if you need more help.
    Good luck
