Modular cable management enhances airflow
Dynamic single 12V rail for power hungry hardware
Thermally controlled ultra quiet fan
Cobra strip cable is neat and manageable

Spefication:-
- Form factor: ATX 12V 2.3
- Dimensions: 150 x 160 x 86mm (W x L x H )
- Typical efficiency: Over 80%
- Power Factor Correction: Active PFC
- Fan:135 x 135 x 25mm, thermal control

Xfire will be fine but if there is one card that can reach higher clock speeds it will be forced to run at the same speeds as the slower one.
I always prefer the look of matching cards.
 
Also take in to account the cooling needed. The upper card will run considerably hotter, so "Blower"-style cards are better suited for crossfire. However, with a proper case and ventilation, and hopefully a motherboard with plenty of space between the cards, you will be fine.
 
Are those akasa psu's any good? I can only seem to find one review of the 650w model, and it's in danish. They say they are 82% efficient but they aren't 80 plus certified, hmm...
 
Well Im about to update my system to an i7 setup, what case/psu etc would you suggest that would suit a crossfire setup? Or I might buy a completed system with an identical card so I could just add my current card. Then I need to think about a monitor to do it justice. I was interested in a 27" but my budget is max aroud £250 for a screen and apparently they arent great at 1080p. Would I be better off with a good 24"?

Some many questions, so little knowledge (or ability :confused: )

If I recall correctly, it is only SLI that require matching clock speeds; crossfire on the other hand don't matter, so long as you are crossfiring cards with the same GPU architecture.

Probably "typical 82% efficiency" means that at around 50% load. Any higher or lower it's different.

80+ cert would require higher standards.

An average PSU I'm sure for a non-hypergamer build.

My SLI'd 670s reach different speeds (and utilisation) under load.
one is a giga WFx3, one is a KFA2.

I think this was true (of both vendors) a couple of gen's ago, but certainly (at least on the green side), not any more
 
You can definitely run AMD cards at different speeds in Crossfire, I was able to with my 5870's, and can with my 7970's. Performance/utilisation balance may not be quite as good as running matching speeds, but it definitely will work. :)
 
why wait for 7950 at all? bring back 7970 matrix and see them being sold out. win win for both ocuk and the consumer. Rep goes up, competitors going down :D

When we did that deal we said last time we'd do a crazy on a 7970 and we meant it.

I recently bought a 550W Akasa Venom PSU from OcUK for a friends HTPC. OcUK have it listed as an "80 Plus" PSU so i assumed it had the 80+ certification, but it doesn't. I read somewhere that the only reason they're not 80+ certified is because they don't support 110V power inputs, otherwise they'd have the certification.

Also there's no mention of the warranty (i only noticed this after purchasing the PSU)... It seems Akasa only offer a 1 year warranty after googling it :eek:. Anyway, the PSU is silent, runs cool and does the job :cool:.
