Question 1

Does it Require more than 550W Power Supply?

Accepted Answer

I'm currently running one with a 700w power supply and it seems like it does need that extra power I don't know if a 550 can run it I have no regrets on this graphics card though, only positive comments specially after buying a second one because of its great price and performance. Running bf4 at ultra, and mining bit coins at 300Mhash/s

Question 2

This is a pci express 3.0 card, will it work with my Gigabyte 78LMT-S2P mobo, since it has PCI-E gen 2 slot?

Accepted Answer

Yes, the card is backwards compatible. As we speak, I have this same model card installed in first, second, and third generation pci-e slots.
It performs very well and temperatures are excellent.

Question 3

Card does not work, the video card looks like it is not getting any power, the fan does not come on and on startup no video, the mother board has no video out put.
Is the card bad???

Accepted Answer

My card worked. I take it your system is not POST'ing. Do you hear any beeps? Have you tried another card? Make sure:
1) your 12V rail isn't getting pulled down, as most high-end video cards pull significant current.
2) your cards power connectors are "well" seated.
3) the card is well seated in the PCI-E socket, you can try an alternated PCI-E socket. Check the motherboard manual for the PCI-E socket priority.
4) If your systems is NOT POST'ing, check your motherboard power connector.

Don't know what else to suggest. Good luck. I think you'll be very happy with the card once you get it running.

Question 4

For anyone that bought it, or knows, does the package come with a CrossFire bridge?

Accepted Answer

It does not come with that.  You get the card, driver cd, manual and that's about it in the box.

Question 5

not working with my intel board getting a 5a post code, and can't get past the intel splash screen. Uninstalled previous driver from old card, reset the cmos, and still nothing. Is this just my problem or are others having issues with intel boards?

Accepted Answer

I have an AMD motherboard and no problems with this card.  I expected problems on my Dell XPS 8300 with another version of the Powercolor 7870 and wrote to Powercolor based upon comments others left on forums about non-UEFI vs. UEFI boards.

Check techpowerup forums.

However,  my Dell booted without problems.  I suggest writing to Powercolor support.  Include the description of your problem and your system info.

BTW, this board is awesome. 400+ KH/s at engine 900,mem 1300.

Question 6

Will this GPU work with my Enermax ATX Mid Tower? it looks like the DVI ports will be upside down. Would that be a problem?

Accepted Answer

this card is double wide, but not as long as the super high end models. the DVI polks out of the card slot on my case and I can plug into either port not problem.

Question 7

Does this card support 3 monitors ?

Accepted Answer

Mine got hooked up in 2 monitors 1 to dvi and 1 to hdmi, but i think u can with 3 monitor since theres 2 dvi port.  GL

Question 8

how do I know if this card is compatible with my CPU? I have a Pavilion p7-1233w. Memory Type: DDR3 PC3-12800, DDR3 PC3-10600, DDR3 (non-ECC) Maximum Memory: 32GB, Currently Installed Memory: 8GB. with a AMD A8 GPU processor.

Accepted Answer

You need to make sure that your power supply can handle it. Mine came with a 550W power supply, which is a good amount. 
If you do get this, please make sure you monitor your PC's temperature with a program, such as HW monitor.

Question 9

I saw some reviews here of people getting over 400 kH/s with this card, what was you mining configuration to get this?

Accepted Answer

I20 WS256 TC22546 GPU1050 Mem1400

I usually pull between 360-420 just depending on pool

Question 10

This says it requires a 500W minimum. does that mean i can just throw in a 500W PSU? or should i go with a 600W PSU?

Accepted Answer

I would invest in a reliable 750W power supply, in case you run a crossfire configuration later. My favorite is Corsair.
