Hey all thanks for all your help with my last question..im going to go out on a limb and hope not to get flamed much..heres my problem

I am in the usa and have 2 neptunes...in preparation for neptunes arrival hired an electrician to provide me with a 240 breaker which he gave me 5 220v outlets. I read up on power supplies and decided to go with the recommendations from knc for 3x 850 w psu/neptune, i purchased the Evga supernova G2. The power cord i was supplied with has the 110v configuration 2 verticals and 1 ground(plug) although after speaking with evga customer support they said it was rated 100 to 240v.. my problem is my local electrician said there are no 220v outlets which can take the power cord i have.
The electrican said he would cut the end of the cord i was supplied by evga and attach the 220v plug...is this safe I DONT WANNA BURRN DOWN MY HOUSE ..thanks all

Same level of safety if correct plugs are properly installed.
Having your electrician change the ends is no more dangerous than having the same guy install the outlets.
Plugs that have screw terminals for the wires are better than molded plugs if you consider they can be reused/repaired.
I'd go with whatever gets the miner hashing soonest, that is also safe, unless there is a huge price difference.

YMMV

Did this myself...made my own 220 box and chopped the plugs off and used the 220 plugs been running stable and cool for a few months now...on eBay there is special 220 plus with c13 connectors on them if your really picky

By code 220v connections require a 30A circuit and 10-2 wire. A 120v/15A circuit uses 14-2 wire.

If you burn down your house because didn't have licensed electrician wire your 220v circuits your insurance company will simply walk away because they and are allowed to.

So is it worth the risk?

'Code' ends @ the wall plug.

You're saying that the wires that came with the PSUs designed for 110VAC will be too dangerous?
I think you missed electricity 101.
The size of wire needed depends on current not voltage.
The insulation on the wire must also be apropriate for the voltage.
They will be carrying 1/2 the current @ 220VAC that they would be @ 110VAC.
I doubt you will find 110 VAC wire that is not also properly 'insulated' for 220VAC.
Listen to the known pro with a license on the line (your electrician).

YMMV
