Just bought the above card to replace an old AMD Radeon HD 6450
When I unplug the old card and insert the new one, connect the 6-pin connecter from the PSU to the new card and power on - the new card led goes solid green, the fans run, but there is not output from the card to my monitor (which then goes into power saving mode).
Can anyone confirm if there is anything else I need to do to get the new card to work on the XPS 8300?
XPS-8300 i7-2600 3,4GHz 12Gb RAM
H67 Motherboard (Dell 0Y2MRG)
Win 7 64 bit
new card is ASUS Radeon R9 270 2BG GDDR5
It wont with the stock power supply and its likely that it wont post at all due to UEFI bios requirements.
I also bought a larger power supply to handle the possibility of the new card needing more power. When I inserted the new R9 270 card, connected the 6-pin cable and powered on the XPS, the R9 270 card's led light came on, the two fans on the card started spinning, but there was no video output from the card. After chatting with ASUS tech support and a separate chat with Dell we determined that the stock 460 watt Dell power supply provided enough power to run the card, but it was not being recognized by the BIOS.
Dell confirmed that the A06 BIOS in the XPS 8300 will not recognize the Radeon R9 270 card. The most powerful graphics card that the XPS will support from AMD is the Radeon 7750. Dell does not plan to release any newer BIOS for the XPS8300 so we are limited to the generation of cards that were known as of that A06 release on 17/20/2011.
The 6950 is more powerful than a 7750

I can confirm that the, EVGA GeForce GTX 970 4GB SC GAMING ACX 2.0 will work with a Dell XPS 8300 with the Ao6 Bios and the stock 460w power supply. My XPS 8300 came with an HD-6870.
