Please help, failed install new graphics card

My computer is definitley UEFI (Maybe EFI, just saying as opposed to legacy).

I see that my current MSI R9 390 does not have the switch, and the sapphire model does. 

2 questions:

1. How sure are you that this would be the cause of the issue? Newegg wants to charge me about a $50 fine for making this swap, i would be pretty disheartened if i did that and it didn't work.

2. Is there a way to fix this without swapping the card? 

Also just a note, my power pins from the power supply say they are 150w(8pin) and 75w(6pin), the card uses about 300w, does that mean the power could still be an issue or is this irrelevant? 

1. Hard to say since I have no personal experience on the issue ... maybe 75% ? [:)] My post above is based on compilation of many forum messages from various users over the years. You are welcome to search yourself.

2. Not that I've heard of. Dell is finished with the CMOS BIOS Firmware on this machine long ago.

3. I stand by my original statement.

In this case, (if it wants 300w) sounds like it would require two 8-pinners. You have those available so it should work. Even if it struggles on the high end (max gaming), doesn't mean it would not boot, post, or work at what is basically idle.

There are physical tools like Digital Power Supply testers and Watts/Amps Meters to help. Software tools like CPUID HW-Monitor, etc. 

Oh the cards just have a 6pin and an 8pin, i suppose the remainder of the power consumption listed is just fluff or comes from some other source. 

For now I'll take a crack at returning this card and getting the sapphire model with the uefi switch. 

I should have the new card in my hands by around May 1st. 

Thank you for your help. I'll post when i get the new card to let you know if it worked or not.

I dont really have any brand loyalty. AMD just seemed better. And sapphire only offers AMD models and they're the only brand with the UEFI switch, so yea i guess im going with AMD.

Oh right ... doesn't some power come from the PCIe slot itself?

Hope it works ... good luck.

I'm assuming you want to stick with AMD (vs going to nVidia) or you wouldn't have purchased one in the first place,

It looks like your right. Someone with an Aurora R3 had the same exact problem and the solution you gave worked. Im confident now. Thank you.

One last question, this guy got the 390x, do you think i should spring for the 390x to be safe, or the 390 would work just fine. Sapphire, of course.

Sorry, I don't have that info handy.

However, I will say ... I think it has more to do with the video card itself and how it supports a hybrid-vBIOS and less about the GPU, speed, etc.

Don't you agree?

There are hardware websites out there that do a nice job of comparing cards.

By the way, would you know of a processor upgrade thats compatible with the R3? Im using the i5 2011 model right now (2.8ghz, 3.3ghz turbo) and i hear that is due for an upgrade as well.

I read that the I7 2600k is alienware reviewved to be compatible with my system. Should i still expect bugs if i go with that one.

Thanks, glad I could help.

No, I don't mind. However, Since there are still some other owners with Aurora-R3, I generally prefer to work though questions and problems in public forum. Maybe it will help others one day (if they search).
