** PRE-ORDER SPECIAL PRICE: OcUK ATI HD 6850 OC ONLY £89.99 Inc. VAT!! **

Hey thanks for the quick replies, my mate just got back to me... not as fast as you guys though lol.

He has...

MotherBoard: GA-890GPA-UD3H http://www.gigabyte.com/products/product-page.aspx?pid=3516#sp (I assume linking to manufacuter specs is allowed?)

Case: Antec 300.

Both bought from OCUK. Crossfire is preferred if possible but I'm not too sure on the spacing, it looks ample but...

 

[Surveyor]

There's no problem linking to the manufacturer's specs.

The spacing on that motherboard is fine.

There'll be an empty slot between the cards which is better for cooling.

The 2 slots will run at x8 speed which is fine.

The Antec 300 fits graphics cards up to 11" long so there should be no problem with that either but they may block some of the HDD bays.

What PSU does he have?

2 of these cards ideally need four 6 pin PCI-E power connectors so he won't have to use adapters.

Hi and welcome to the forum.

Not a lot from what I can see.

The V2 requires two 6 pin power connectors and the V1 only one 6 pin power connector (as do most HD 6850's).

Just guessing but perhaps that allows the V2 to overclock a little further.

I think I may have a problem then with my PSU. I have a CX430 builder series PSU. I'm not sure, but I think it only has one 6 pin power connector.

Can anyone confirm if this will/won't work with the Corsair CX430 Builder Series (rev1)? I'm not 100% sure about what I'm looking at. Thanks.

It's not a bad PSU but only 336W on the important 12V rail.

Review here.

You can use a molex to PCI-E adapter (supplied with the card) for the second power connector.

You should have enough power depending on the rest of your system and how high it's overclocked.

Guru3D's tests have their system (a power hungry Core i7 965 / X58 system overclocked to 3.75 GHz) drawing about 300W from the mains with a modestly overclocked HD 6850 at full load, so around 270W output from the PSU.

Think i might risk it, but could likely be a dsr if its noisy

Meh

If I remember correctly he has a 700w but I can't remember what brand, I have a spare 750W CoolMaster but that isn't exactly the greatest PSU going, replaced mine with a 850AX from Corsair.

Am I right under the impression that would be sufficient in wattage?

Four, 6 pin? My HIS 6850 only uses a single 6pin I think?

Edit: Sorry, I forgot to say thanks for helping

I probably wouldn't overclock either the CPU or GPU on this PSU. I'd wait until I had a better PSU. But thanks, that was helpful. Should be fine for my modest needs.

You're welcome.

Most HD 6850's only have one 6 pin power connector but the card in this offer has two.

The 2 PSU's you referred to have sufficient wattage taken at face value but we really need the specific models.

Some 700/750W PSU's are crap, some are OK and some are fantastic.

According to his order history from OCUK it is...

"OCZ ModXStream Pro 700w Silent SLI Certified Modular Power Supply"

Looking at the specs it clearly doesn't have enough 6 pins, that would mean he would have to use the molex adapter for both cards. Is that even advisable?

 

[jaybee]

What is this card like in comparison to a 5770?

It has 2 PCI-E power connectors and 552W on the 12V rails.

Guru3D have their system with CrossFired HD 6850's drawing around 400W from the mains, say 360W from the PSU.

I'd say he'll be fine.

Use one "proper" PCI-E power connector for each card with the second one from a molex adapter.

Be aware that he'll need to use all 4 of the molex connectors from his PSU for the adapters.

Hmm that sounds like it would be problematic, he won't be able to power any of his case fans if that is the case. I guess using a molex splitter would be out of the question due to the nature of what it's powering?

edit: I do have some molex to 3/4pin converters for fans but that seems like he's going to have cables everywhere haha

I find it difficult to answer that one.

You can get single molex to PCI-E power adapters which might do the job leaving 2 molex connectors free.

I can't imagine that these cards use that much more power than those with a single 6 pin connector.

edit: I do have some molex to 3/4pin converters for fans but that seems like he's going to have cables everywhere haha

How many molex connectors does he need for his fans?

If he has SATA connectors free then this might be an option:

Akasa SATA to 4pin Molex Adapter

(For the fans not the graphics card).

 

[Laher]

Isn't the 7770 supposed to be faster than this (When it comes out) and in a similar price bracket?

Is that why you're giving a price drop

Quoted from earlier in another thread on this offer:

Yes for the manufacturer, hence me getting the deal I wanted.

We shall be selling 7770's at £130-£140ish, so even then this card is superbly priced.

7750's shall be around £105-£115.

As such this is bargain!

Also remember this 6850's are 256-Bit memory interface, wheras the 77xx cards shall only be 128-bit, as such it is still unknown if the 7770 will be as quick as a 6850.

You were in such a rush to post your smart comment you must have missed it

I never knew those existed! He has two spare SATA power cables and 3 case fans that he "needs", Top, Rear and HDD (will supply cool air to the cards). So it looks like this will work out for him...

Edit: thanks again

You're welcome.

There are quite often ways to get these things to work.

I hope all goes well for your friend.

for the money would 2 of these would make a nice upgrade from my 280gtx, or would i be better running a higher spec single card, main games black ops/bf3/hldm

 

[Flashheart]

Two of these will put you in gtx 580 territory. There isn't much else that will touch a pair for £180 dude.
