    new gpu not working...?

    Hello,

    I’ve looked everywhere online for help but nothing works.

    I recently bought a new rx 460. I installed it in my pc and plugged it with DVI cable to the monitor.

    The card gives no video output…

    I tried entering bios using the the integrated graphics card to see if I could change the primary video output option, but can’t find it. And, neither does BIOS or my OS detect the card, at all.

    I’ve tried taking the card out and installing it again. It draws power from the moab, as its fans work. I tried removing the CMOS. Nothing works.

    It’s really frustrating and idk what to do. Can anyone help me?

    Could it be my PSU is too weak?

    What is the brand and model name or number of the PSU.

      It’s a OEM psu, it came with the MT. My PC is a Dell Optiplex 9010, with a psu of 275 w

          Sorry to be the bearer of bad news but even the 2GB version of the card requires a quality brand PSU with a minimum of a 350W output and 23amps on the +12V rail, the present Dell PSU may be labelled as 275W but if you check the label on the unit it states a maximum of 240W which is worse still.

          You are welcome btw

            Oh crap

            So.. forgive me but I’m new to tech upgrades.. basically the gpu will draw power but not enough to actually function?

            Could this be the reason why it wouldn’t work?

              In essence yes, as the RX 460 does not require a supplemental power dongle from the PSU it must get what it requires from the PCI-E slot on the MB and there just isn’t enough juice coming from the PSU to power the GPU.

                Ok! When purchasing the gpu, I thought my psu would be enough.

                Would a 400w one suffice? If so, how do I know which one to buy?

                  For the present hardware and the RX 460 a good quality brand 400W PSU would be fine, you may find that a 500W PSU will be less expensive though.

                  In which country will you be making the purchase.

                  Is your Dell Optiplex 9010 the Mini Tower model.

                    I’ll be buying it from Ohio, USA, and yes, it’s a mini tower!

                      I dont normally recommend the CX range of PSU when there is an add on GPU involved but your card is not too demanding and the unit here is over and above what the RX 460 requires, it was also the least expensive at only $19.99 after claiming the mail in rebate, it has a five year warranty as well.

                      [COLOR=rgb(41, 105, 176)]NB: The Corsair PSU measures 3.39" x 5.91" x 5.51" please measure and compare the size of your present PSU to make sure that the Corsair will fit,[/COLOR]

                        Got it, thank you!

                        Would this one Amazon.com work well too?[/color]

                          Nope, wouldn’t touch it, the fact that the unit is described as 80+ White means that it is entry level and you should never use anything less than Bronze efficiency rated, it is also more expensive than the one that I suggested after you had claimed the mail in rebate, the branding on the PSU is also a con as the PSU has a maximum output of 384W, you can check this for yourself on the information label here

                          Please check the PSU guidance links in my signature below for brands of PSU to trust and brands of PSU to avoid, brands to trust include Antec, Corsair, EVGA and Seasonic.

                              What do those measurements mean? Height, width and length?

                              On Newegg and Amazon, these measurements aren’t set in that order so (sorry to sound silly) I don’t know if any of these psu s will fit ?[/color]
