Here are the specs of the PSU:
http://www.lc-power.com/product/netzteile/silent-serie/lc5550-v22/
Overall it can provides 38A on +12V rail.
A single 4870 (combined with the entire system) needs 32A on +12V rail. How much the rest of your system pulls, depends on the exact system specs, so post them if possible.
All in all, I cannot find any trusted reviews of this PSU - it is certainly nowhere near Tier1/2, but it certainly doesn't look like a Tier 5 PSU by a long shot either - it is 80 plus certified, Haswell compatible and contains several protective circuits. I know several people who used older versions of LC Power supplies, and noone had a single failure. One of them even used 7950 card with his 600W LC Power for several years. Still, they look like they are more suited for office builds than gaming rigs, but in your case it should do the job, provided you don't overclock anything.
Too bad there are no decent reviews... they are quite common in some countries.

So we have approximately 120W of wattage for CPU+mobo+RAM (under full load), and the only other serious power "user" would be that 4870 GPU which usually pulls 170W under full load. So, you are looking at a grand total of 290W, let's round it to 300W. And this is only the worst-case scenario, will max load on all components under stress test, very rarely could a game use all this power.
38A on +12V rail equals 456W, but if we assume that the PSU is not really top-notch and likely not brand new as well, this would likely be closer to 400W. Some headroom like this is always a good thing, because PSU won't have to work too hard, and remember that you will very rarely, if at all, hit 300W consumption.
All in all, I believe that you are OK with this PSU and this GPU. Now, if you upgrade anything later down the road, make sure to check the consumption again.
