EVGA's Gargantuan SuperNova 2200W P2 Can Jumpstart Your Pickup Truck
EVGA this CES showed off its flagship PSU, the massive SuperNova 2200W P2. This unit has enough juice to power a gaming+mining rig with up to 9 graphics cards, or to jumpstart a pickup truck. Under the hood, it features a single +12V rail design, with an impressive 183.3A +12V rail (~2199W), and 24A rails over the +5V and +3.3V domains that work out to 120W. DC-to-DC switching converts power between the domains. The PSU boasts of 80 Plus Platinum switching efficiency. A 140 mm fan keeps the unit cool. Among its constellation of output connectors are one 24-pin ATX, two 4+4 pin EPS, eighteen 6+2 pin PCIe, twelve SATA power, six Molex, and two Berg.

Your battery is rated at 100Ah, which is the capacity of the battery.
Yes most car alternators are between 65A and 150A, at 14.4v when running (not just 12). Or 936 to 2160w. This is not what starts your car, that's the battery. The alternator generates enough current to run the car's other electrical stuff and charge the battery while you drive. This is why sometimes you may notice your car having trouble starting after making a lot of short trips. Pro tip, if your battery is low and you have a manual transmission car, you can do what's called roll starting. The battery usually needs a large capacity to run the starter. The starter has to get enough power to turn over the whole engine. In many cars the starter in a 4 banger may not be much smaller than a V8, although some do have much larger starters. Most batteries I've seen range form 440A to 800A, stock. That's about 5000 to 9600 watt depending on the starter size. Also, keep in mind the battery usually can't run this much power much longer than a minute or so of trying to start the car. Remember, the starter runs off the battery trying to turn the crankshaft of the engine, which moves your timing belts/chain, camshafts, pistons, valves, water pump, distributor (older cars) and all accessory belts as well and so on. So the more things running off your engine, the harder it would be to start. Some people buy a larger battery so that they either get a quicker start up or so they have more power when it's cold, as you could lose quite a bit of battery amps in cold weather. Another reason is for people who have larger stereo systems that need a lot of juice, like sub-woofers. This is why sometimes you'll see a car's lights dim while the bass hits. A capacitor, larger battery, or higher amp alternator usually helps, or all 3.
As for the power supply... I don't think I could even use that thing in my apartment lol. I like that it supports basically 3 high end cards in SLI/Crossfire. I've seen a handful of high end cards that use 3 8pin connectors. I don't just mean a 1080 or titan, I'm talking the custom stuff. Not that I could afford either, though a customer of mine might in the future.
As for use in a rack chassis, why not use server grade 1U/2U PSUs? Sure, they're more expensive, but far more compact again, and usually the best quality you can find. Of course they're also noisy as all hell, but that comes with the territory.
