That is 20amps peak. PSU's are rated in total wattage/amperage. Someone mentioned fires with these chinese units as well, be careful. To rehash the psu notion around here.
Here are some possible options.
XBOX 360 psu ~230w = 19amps on it cost 20-30 bux. And some hacking.
ATX psu ~ 250-1kv depending on the type, 20-350 bux and honestly not a good choice.
Chinese PSU 250-400w 20-60bux, however unknown standard and longevity, signal noise etc.
Name brand industrial psu ? not sure, never looked into them as they were out of my budget.
The option I used is none of the above. I got my hands on a used IBM server PSU, did some googling and hacked it to work. If I had bought the thing it would have cost me about 20-40bux used. Its rated for 1300w @ 220v input, and rated for about 650w at 120v. So either 54amps or something like 117amps at 220v. It does not care if the input source is not clean, it does not care if the input power is not stable, it will always put out 12.3v. It runs cool with the original fan and gives me enough room to add a secondary heater to my build and then some. I have enough amperage to accommodate two more printers on the same psu and it still would not sweat. Its built like a tank, its fairly efficient and for me it was 100% free. My buddy pulled it out of the recycling room at his job for me. Down side is that it is relatively loud, but no more than the printer is when its moving. I am happy with that.
