|Members in US can't use this PSU, but people who live in UK can use this PSU.
So if you want to overclock at home, you need to move to UK.
You could use this PSU just fine in the US given that you have the correct wiring to support it in your house. You can easily upgrade a 15 amp circuit to 20amp as long as the exhisting wiring will handle the additional current. If your only using a 16 or 14 guage wire then you wouldn't want to swap the breaker out you'd be asking for a fire, but if you had a reputable electrician who put the good stuff in (in most case's not because even million dollar homes are built like sh-- these days) you'll have 12 guage wire which is fine for a 20 amp circuit, if this is the case you run down to your local home depot drop 10 bux on a 20 amp breaker and replace your exhisting 15 amp with the 20amp, (notice to those who may actually try this MAKE SURE TO TURN OFF THE MAIN'S POWER FIRST!!!!! THATS USUALLY THE REALLY BIG TYPICALLY 200AMP SWITCH AT THE TOP OF YOUR HOUSE PANEL
)Ok disclaimer done now, but yeah thats all it'd take and you've now got a circuit capable of 2400 watts of supply.
