Crossfire HD4850 + HD4850X2 With 500W?

[T TelDa]

I have a HD4850 for Christmas and I am planning to buy a 2nd but I recently discovered that the HD4850X2 was released. So I was wondering if it was not possible to make a Crossfire with a HD4850 and HD4850X2?

I thought also take a new CM for Christmas but I make a request to upgrade the time wanted. I also have a food Enermax 500W equipped with 2 PCI-e taken (the HD4850X2 need to go 2) I would have put an adapter molex> PCI-e I have 500W but suffice it?

My current Rig is:
E6550@2.33Ghz o / c@3.10Ghz
HD4850
G-Skill 2GB PC-6400
1 HDD 250GB a 7200rpm
more about my food there: 6 fan 120mm + 1 + 1 fan 200mm pump (18W) + 2 neon blue 30cm.

Hi,

I had some google search to find out the answer on a topic, someone asked the same question, he already had a power 500W Seasonic brand in general people advised models of 600-650W if 'purchase history to have the margin, others said it was not enough and others not, but good when he had his crossfire of HD4850, in the end it worked

Instead of the food I am concerned about whether a crossfire of a HD4850 with a HD4850X2 is possible .You're of course that it can be done this thing here?
Otherwise you clarified many things --- except the mark of your food model etc
you find it a pity not for a topic on a question of power .I think 500Watt is "fair". you will have to make choices:
1. Turn all the gadgets and pray that your password crossfire with your food 'of 500Watt.
2. Buy a new food '

Already I think the idea of putting a HD4850 + a HD4850X2 is not a good idea, you see a bit much, you play on a screen how many inches? although I have no idea if this is possible or not.
But there 500W it will not be sufficient in this case definitely.
Why not settle for a "simple" crossfire of HD4850?
