Some of them do have admirable performance, but nowadays you have many other options out there which perform similarly, but at a fraction of the price.
Alright fair enough. I cant disagree with that. Since they were named the best PSU company of 2010 they can jack up the prices for their name. While I dont really find a problem with this since its just good business I am a bit sad about it. At least they still offer some of the best PSUs around. Personally I would pay the extra for a Corsair PSU just because of their awesome warranty, great PSUs, and great customer service.

u would be fine i used 2 gtx 460s with my i7 on a 600watt psu....and i think the power draw of hd5850 is not much higher than gtx 460's.....and the fact that u r using a quad i5 which consumes less power than an i7.........

Yes, the customer service and warranty is definitely great. Won't disagree.

However, XFX is coming up as a pretty strong competitor, using a full fleet of Seasonic-built supplies.

As long as they don't screw up and go HEC or something, like Xigmatek did, XFX may just overtake Corsair in the power supply market.

Little update. I have a modxstream 600w, which is considered worse. Is this psu going to be enough?

Bump. I suppose I will need a new one psu for 5850 crossfire. I've been thinking about Corsair TX850. I know it is clearly an overkill even for my updated setup [i5 750@4GHz, 4GB ram, HDD&SD, 5850 xfire, p55 ud4] but it will outlast even my future upgrades for sure, lol.

From what I've read - p55 ud4 is a good mobo for crossfire. Right?
btw, are they still manufacturing HD5850? It's not a problem to buy it, I've been just wondering. Guess not.

Another question, important one.

Can I pair a reference card with non reference? In other words, can I mix my powercolor reference 5850 for example Sapphire Vapor-X HD5850 1GB? If no, reference + reference although other manufacturers will work I hope?

Yes, you can mix non reference cards and reference cards.

I think it would work but it'll be close to the PSU's limits. The ModXStream 600W delivers up to 504W at 12V. Two stock 5850s will draw about 280WDC while running Furmark (worst case scenario). That leaves you with at least 220W for the rest of your system, which should be fine.
In short, don't go running Furmark and IntelBurnTest at the same time. Beyond that, I think you'll be fine.

Edit: if you get a 850W unit, then definitely don't get the Corsair TX850. Make sure to get the TX850 V2 at the very least (just released a few days ago). The XFX 850W (http://www.newegg.com/Product/Produc...82E16817207008) is the same unit as the TX850V2 and costs less. The XFX 850W Black Edition (http://www.newegg.com/Product/Produc...82E16817207001) is an even better unit and costs even less after a rebate.

The TX-850 is a good PSU. Try getting the newer TX-850 V2 version if you can.

Edit: Your ModXStream Pro 600W is a decent PSU so you could make do so long as you are not overclocking too hard. If you plan to OC, probably get a 700-750W.
