My friend has recently acquired a new Gigabyte R9 380 (as well as a Rosewill RD 700-M 700W PSU to support it). His plan was to upgrade his prebuilt computer (Dell XPS 8300). He first installed the new PSU which works fine. His new graphics card, when installed (and of course plugged into the psu with 2 full 4-pin connectors), doesn't seem to even get to the BIOS screen as it never displays anything. His hard drive normally makes a click on startup, and it does so here, but completely shuts off after, though the lights on the card will remain on.
If he only connects 6 of the 8 pins the computer starts up fine but only uses the onboard graphics, but again the 380's light remains on.
If he connects NONE of the power connectors but still leaves in in the motherboard he gets the same result as plugging in only 6 of the pins.
What gives /g/entleman?
you should have listened to Mr. Huang and bought NVIDIA® goy. now a world of suffering delivered by the gods will come to you
there is still time to repent. buy NVIDIA® and free yourself from all graphics card worries
I am currently experiencing something similar. Asus R9 390 and 850W PSU. No POST screen or any display at all, but the machine does boot up. If I connect a second card, I get a display on that card only. The R9 is detected by my OS, but it doesn't see any monitors attached to it. My current guess is that the card is working, but can't detect monitors for some reason.
get yourself either a dual 6 pin to 8 pin, dual molex to 8 pin, or 6+2 to 8 pin.
>6+2 is the same as 8pin
i was recently having some issues installing a evga gtx 960 in a friends old gigabyte motherboard, i googled my problem and had to change some weird setting in the bios to legacy. try to find that, will probably fix your issue
I've tried with and without on both UEFI and Secure Boot (at least I think I did, ASUS bios has some odd wording). I did get the card to post at one point, but after I closed the case, shifted it 2 feet to its spot and plugged everything in it stopped working again.
