Yes, those cards will work in CF.
Yes they will work fine on that MB.
I would not trust that PSU with those 2 cards. It is not a very good quality PSU. But if you want to chance it, the +12V rails should be sufficient.
(48amps @ 540W)

Thank you for your fast response, I'm going to chance it...and risk having to buy a new PSU if it craps out.

you can chance it, it'll support the cards according to the PSU specs, and should be doable, the PSU quality is terrible, but is sufficient enough.

Whoops....I posted the wrong psu...dont know where that came from...my actual psu is this

That PSU is fine, it is good enough quality for your setup, Go for it!

Rosewills are mostly good PSUs. Newegg's in-house brand. The HIVE is one of the better series. I have had several on the builds I have done for myself and others. In fact, I have the HIVE 750W in my 2nd machine now. That 650W will be adequate for 2 x hd7850s. And since each hd 7850 only requires one 6 pin cable, you are good there too.

So, I have the new 7850 card, and have installed it alone first to be sure that it works...alas, I got a black screen. So then I took it out and reinstalled the visiontek one that I already had...and I get these strange vertical corrupted-looking vertical bars as its posting, only to turn completely blue after the windows logo. Ive reseated the ram, cpu, removed all unnecessary hardware and attempted both pcie ports. When I tried the new one again it now does the same thing (vertical bars) I updated to the latest beta bios to no avail....

I am now posting from said computer running onboard hd3000 video and it works fine.

Did my mobo die?


not funny lines

Strange that it was OK until you swapped cards. I assume the Visiontek was originally in the 1st slot for some time with no issues? How are you connecting to the monitor?

 

[vulgarthegreat]

it was in the first slot, and I was connected through hdmi but I also tried dvi afterwards, Im going to try to rma the cards, my friends card works fine in my rig, and neither card works now on my friends computer, while his own still works.

Wow. Lucky to have a friend that allowed you to use his card as a Ginnie pig after your 2nd card died. Did his card also require a 6 pin connector?

 

[vulgarthegreat]

We actually tested a Radeon HD 5750 first since we didn't care if it crapped out. Once that worked we tried his Geforce 660 OC Edition which has one 6 pin connector.

 

[clutchc]

Very strange that the problems all started after you swapped cards. I would suspect damage to the MB from the new card, except for the fact that the friend's card worked OK. Have you tried your original HD 7850 again to see if its working now? Or did you RMA it too?

 

[vulgarthegreat]

I retried the original and it does the same thing, both cards are somehow damaged, Im confounded by the timing. But i guess stranger things have happened than 2 nearly identical cards having the same failure at the same time, maybe I have gremlins.

 

[clutchc]

No. There's something wrong. Not sure what, though. Lets us know how the replacement(s) work.

Will do, it'll probably be a week or two until the replacements bet back. I'll try them one at a time to make sure before I Crossfire.

 

[vulgarthegreat]

got the new cards, works fine now.

Excellent! I've never heard of 2 cards failing at the same time. Maybe one bad card fried itself and the other one when it powered up.
