I have a 220 volt outlet, my PSU supports 115-240v, but the plug is only a standard 120v plug. How doninokug it in?

There should be a switch that flips the input between 110/220 and you will need a different cable for the PSU

Will that work for US split-phase “220” where the voltage is 110v on each leg? I was always worried that would fry the PSU since it’s not true 220V.

Yep

It’s not? I guess it’s more like 230-240 but it should be fine,

“220 V” is the “nominal” voltage. All voltages fluctuate depending on all sorts of factors, but should stay within a certain range of nominal. In the USA most utilities follow the ANSI C84 Voltage standard. 220 V is what electricians refer to it as. Your utility probably calls it “240 V”.

It’s functionally the same, it’s not fake in any way.

It’s just a transformer that has 240V across it with a tap in the middle, and we take the two halves of it to make the two 120V lines. Combining the two 120V is really just using the whole transformer.

You’d see exactly the same curve on an oscilloscope.

Right, where do I find the cable? I can’t find it on evgas website or anywhere else.

notfromhere , 11 months ago

Can you upload a picture of the plug because it should be easy to find standard cables?

average650 OP , 11 months ago

Someone else has given me what I need I think ,but it looks like the one here:. www.evga.com/products/product.aspx?pn=220-T2-1600…

That’s the titanium model, while I have the cheaper gold on, but I think the plug is the same.

Sorry I meant your power outlet. The outlet on the PSU is standard for 220v from what I know

Looks like this: images.lowes.com/product/…/032664306303.jpg

It looks like I need a 6-15P to IEC C19 cable. I guess 14 gauge should be sufficient.

Edit: Wait…It might be 6-30… That’s way harder to find.

notfromhere , 11 months ago

Yea I can’t help you there. That NEMA 6-30P is going to be tough to utilize for this and could be dangerous. Good luck on your hunt. My only suggestion is maybe fine a PDU that could go between. I do not recommend making your own cable.

average650 OP , 11 months ago

Could I not use a 6-30P to 6-15R adapter? My computer will blow up before that amperage becomes and issue.

notfromhere , 11 months ago

I’m not an electrician. I would assume one adapter in the line would probably be fine if it’s a good quality adapter and no chance of coming loose. I would be worried about shorting / fires and would want an adequate breaker behind it, maybe arcflash.

You can get someone knowledgeable like an electrician to just change the outlet itself to whatever is best.

From google images it looks like this PSU has an IEC C20 male connector on it meaning you would need an IEC C19 end on your cable. C19/20 is a higher amperage version of C13/14 which is what could be considered standard on a normal consumer PSU. Google C19 to whatever plug your 220v outlet needs and you should find the appropriate cable.

average650 OP , 11 months ago

Okay! Thank you. I think that should be what I need.

average650 OP , 11 months ago

But the way, do you have a resource for the names of different plugs/connectors?
