Hi, my current rig is:
- Cooler Master Trooper
- Noctua d14
- Asus Z68 V Pro gen 3
- i5 2500k at 4.ghz
- Saphire hd6870 1gb
- Seagate Barracuda 7200 2tb
- Cooler Master iGreen Power 600W

Now i just want to buy another hd6870 and do a crossfire, but i have doubts with my psu.
its exactly this: http://www.extremeoverclocking.com/reviews/cases/Cooler_Master_iGreen_600W_1.html

It has 600W continuous and 700w Peak, but i know this is not the most important thing about the psu, it has 3 rails, 2 at 19.5a and 1 at 19a, so a total of 58a.

it has 2 6 pin connectors and i need 4 for the cf so i can use the adapters that came with the card.

so the question is simple, can i do that without being dangerous? Can that psu with this cf?

I can get another hd6870 for about 100$ or sell it and get a 7870 for about 200$.
what would be the best option?

Thanks and regards
 
i have said it 100 times, but i had xfire 6850's, bought a second one after running ok with the first for over a year. sold both within a month of getting the second one, crossfire is poo, doesnt work on all games, stutters on many games, works well on only a few games. plus the 1gb vram on those cards is a limitation, with many games using over 1gb vram now. sell your card and get a 7870.
