Yes it can cause the coils to pop. You want to stay around 8 Watts of power.
P = V²/R
P = power in Watts, V² = voltage squared, R = resistance of atomizer in ohms

8 watts is at the low end for anyone who uses variable voltage.
A modern carto or atomizer of around 2.5 ohms, nothing special just good quality, can readily handle higher total power. I normally run 2.5 ohms at 5V (10 watts), will nudge it up towards 12 once in a while, and know others who regularly vape up in the 12 - 15 zone.
A single coil low resistance (1.5 ohm) off the shelf atomizer/carto may have more problems at higher total power, not sure, I only use 2 - 3 ohms.
Higher power than that I've not dealt with (my own PVs only go to 15W total).

Agreed with markfm. ridethespiral's suggestions is a good rule of thumb for starting -- but higher resistance equipment gives a lot more variance and tolerance. 11-13w is my average, depending on the atomizer setup I'm using at the time.
Baditude posted this to a question I had about Ohms. After a bit extra research I found the majority of people Vape between 7-8 watts. The chart shows you at what voltage combined with what Ohm rating gives your the desired Wattage.
There is also an article that goes along with it which I am looking for right now. Basically, once you go into the "red" zone, it can cause failures in most off the shelf products and reduce the life of pretty much everything. If you drop to the yellow zone, you get crappy/no vapor. Looking for the article about power levels right now
PharmTechDude: You are correct, and that chart is good knowledge to have... but don't let that chart make you think that there is no vaping above the 8.5w mark. Its a good rule of thumb, but its only that. They make devices with higher amperage protection for exactly this reason -- trying to drive a stainless mesh wicked Genesis style atomizer 8 watts will only frustrate you. I barely get vapor production below 10w on mine -- but they explode out when crossing to 11-13w..
Most people, myself included, are pretty happy around 8watts. I've done higher, but the carto's last longer and I find the flavor is better for me, with what I am using, at 8watts. I've heard of several juices that do tend to taste better at higher wattage, but I've not used any of them yet.
An easier rule of thumb to get started, take the resistance of the atty and add 2 to get a decent place to start out. This will start you in the 8 watt area each and every time, then you can work around from there. This is around what the chart above does, but it's easier for me at least.

That is a good point, and why I said "most off the shelf stuff" There IS an entire market out there for the hi-power guys that want to crank the voltage wayyyy up. I seen replacement heads for some of the attys with 10 Ohm ratings. A head like that on a standard Ego probably wouldn't even get hot enough to vape anything, let alone give you a decent hit. But at the power level required for a 10 Ohm head to work, and switching to a "standard" head rated at 1.5 Ohm would most likely turn your PV into a 1 hitter quitter.
We cant go 2 feet without stumbling over a dozen 1.5 Ohm cartos/heads. You have to look around and sometimes leave your familiar websites to find the "big boy" stuff that you drive with a power source that makes the rest of us envious.
Found the original article BTW

whoa, 10 ohm coils? Whered you see that? I've not seen anything over maybe 5.... and I don't personally use anything over 3 
I can't even imagine the device that would fire it! 12 volt? 24?

Looking for it. Might take a bit, I was searching website after website for almost 5 hours last night looking for the best deals on the kit I ordered. Watch me put my foot in my mouth and I seen 5ohm 10 Watt and thought it said 10 Ohm
Even 5 ohm seems excessive to me... I can max out my Provari's w/ 3 ohm equipment, and still not be at a point of burning juice -- can't imagine needing more than that.
I know a few places make 4.5 and 5 ohm attys, MadVapes has several of em. But I certainly don't have something that can crank the wattage they'd surely need.

I won't be referencing that article.
" the next area is the redish area, you want to avoid these levels at all costs as these power levels can burn up and destroy attys and cartos", with the chart legend talking about melting solder and wire, just doesn't match the reality of how I, and many I know on ECF, have been vaping, for a long time now. We aren't using special super-duper high resistance atties, we are regularly running 10+W with normal, stock, products. I know it was written with good intent, and actually sounds a lot like common wisdom back in the 2010 timeframe (atty/carto build quality has increased since then, specifically due to people choosing to vape at higher power as a norm), but is simply not an accurate portrayal of the current state of vaping products.
5 ohm I'd readily believe. Back in 2010 before VV, people would stack two 3 or 3.7V batteries, no regulator. Fresh off the charger the stacked 3.7 would be 8.4V. A 5 ohm atty at 8.4V = 14.1 W, briefly, before dropping down to 7.4V. Pretty high power, but absolutely in the zone people will regularly do today, with much lower voltage and lower resistance atties/cartos.

The chart itself, despite its flaws however, is a convenient reference to have on hand... At least the one posted directly in this thread is, IMO. Not that the math is hard to do -- W=V^2/R -- but can be a time saver if you're trying to get out the door right after spinning a new coil by hand, and just want to verify what your typical sweet spot is. I pretty much ignore the color coding
For a starting point, setting voltage to sawlight's "R + 2" really is good. That gets you just over 8W, a decent starting voltage. On the PVs I use, since all my cartos and atties run in the 2 - 3 ohm range, I just start at the center (4.5V), nudge up or down to taste; my mods don't display voltage, just a basic thumbwheel.
But I know my sweet spot on most my favorite juices -- I just need a quick reference to reach it... Beyond that, you can just step thru voltages to find the sweet spot -- but I still find it a convenient reference. I've kept a copy of it on my webserver for nearly a year for personal use. I just ignore its guidance as to whats too much and whats just right.
References are good. I don't need it only because I'm a nerd (engineer by trade), so the math is automatic for me.
I'm a networking engineer -- but I'd be lying if I said that the math just flashes into my mind for me. I more deal with traffic flow and topologies, so I don't get to utilize it that often at work. Definitely a hardcore nerd as well -- and for the most part I already know what settings I want. I just keep the reference around for if I'm in a hurry and had to recoil one of my Genesis tanks
