The perfectly reasonable 2 kilowatt Superflower is only able to provide a paltry 166.6 amps on its single +12v rail so you will need to be absolutely positive that your rig will not need a more powerful source of power.  Available only in the UK, it is possible that Superflower is not exaggerating when the claim it will accept 100V~240V, perhaps a budding North American electrician could set up a test to see if this 80 PLUS Platinum rated PSU can actually be powered by any mere wall wart.  No ones seems to mention the weight of this PSU but it does measure 150 x 86 x 220 mm which is a pity as this PSU would be perfect for an mATX build.  You can catch a video of this PSU in action on the last page of the review, powering a PC not an arc welder.

"‘Holy Moly’. This is the PG version of the first words I said when we were offered the new 2000 watt Superflower power supply for analysis. Renowned and highly respected UK overclocker Ian ’8Pack’ Parry partnered up with SuperFlower for the creation of this new monster unit. The ’8 Pack Edition’ is a fully modular design, 80 Plus Platinum certified and ships with enough cables to choke Godzilla."
