Will a Corsair 1600 Watt power supply rated for 200-240 Volts A.C. input work on 120 volts A.C.

[HIGHLANDER58]

I bought a Corsair 1600 watt power supply from Newegg and although I live in Canada, I received one that is rated for 200-240 Volts A.C. input. The power supply came sealed brand new with a cord for 200-240 Volts A.C. the seller also threw in the correct power cord for 120 volts A.C. When I contacted him to tell him, he swears that they sell many such units to Canada and that it will work correctly but I am not so sure. If anyone here knows for definite if it will or wont work please let me know.

Take a look at your box. My AX850 says "Auto-switching circuitry allows universal AC input from 100V-240V"

No it wont. Operates on 200-240V only! See here-

I took a photo of the box where the English specs are and no where does it state universal 120-240 volts A.C. It only says universal 200-240volts A.C. so I must conclude that this particular power supply wont work on 120 volts

I would definitely play it safe and not use it, not that I think that less voltage will harm it but they do have models for 110/120V. The homepage is not very helpful.

 

[Hugis]

Says right there 200-240v input, ie not 110-240V

 

[HIGHLANDER58]

I know exactly what it states obviously since I have it in front of me, my reason for asking not that I have to state the obvious is the seller claims they sell hundreds of these to Canadians and that they apparently work just fine, despite what the label states so naturally I want to know if anyone who has received one of these 200-240 models has actually tried it on 120 volts A.C and to state the results.

 

[R0H1T]

Well if you can test it out on a spare/old system that'd be for the best or if you have some PSU tester?

It should work because most products sold these days are basically the same units that ship to NA/EU & Asia so they generally support 110-230V input range.

Unfortunately I have no proper way of testing this or I would have the moment I opened the box and realized the seller screwed up. I only know that some power supplies although rated for a specific input voltage will work if connected to a different voltage, all that would change is the rated efficiency of that power supply would be different but I have no way of knowing if this power supply is one of those or if it will not even power on. If no one here is able to shed any light on this dilemma , I will try and contact Corsair tech support when it opens up in about 2 hours and 20 minutes from now on the west coast.

That's your best bet, as this could simply be a packaging issue. With Corsair's reply you'll also be covered for any mishaps, so try to get a clear answer & proceed accordingly.

I think my reply is pretty conclusive, it won't work

So you'd rather believe random dude selling you stuff than official product specification?

Even if it does work at 120V (quite possible), the bridge rectifiers may not be able to carry the full current at full load. i.e. it is not enough to just test it on partial load.

Hi, This has absolutely nothing to do with believing random dudes off the internet, it does however have to do with over 40 years of hands on practical experience in designing and building as well as repairing countless power systems over the last few decades. I agree with a reply earlier today that states that practically every device these days is designed to operate between around 100-240 volts A.C whether it is stated on the device or not. The only issue I really see here if one can call this an issue is when the power supplies are made and tested and the procedure used to attain the various efficiency levels such as 80 or bronze or any of these familiar ratings, a set and regulated input voltage is used for any given power supply and the country in which it will be used in. Since I will be using essentially half the input voltage, I fully expect that the input current will be exactly twice of what it should be for any given load since as we know from basic electricity ohms law so this power supply more than likely wont be operating with the claimed 94 percent that its advertised as but as long as the load does not exceed the maximum input power draw, everything should work fine and to that end, I have done a couple preliminary tests already by turning it on the bench with a dozen case fans as a small load. It powered on just fine and the self test did its thing and the green okay led came on. I then ran it for 30 minutes with no issues and every single out put voltage is dead on where it should be. The only thing left to do is put a larger load on it as well as measure the input current draw which as I said earlier, I expect the current draw to be twice what it otherwise would be but my system wont be putting to much of a load on it anyway so I do not see any issues, at least not yet.

Your link also states:

Voltage Compatibility: 110 V

Right alongside warnings it is 220V only.

Wtf is up with the mixed messaging on this thing.

 

[newtekie1]

This is a AX1600i, the first batch said 200-240v, but they would run at 120v. They are fully active PFC after all. HOWEVER, the unit is derated when running on 120v. The unit can only supply 1300w with 120v input.

You can see the updated product sticker here:

 

[Shrek]

Fascinating

1600W 115V - 240V
1300W 100V - 115V

so one might argue full load is possible at 115V

 

[juular]

It's 1.6kW at 115V and up, or 1.3kW between 115V and 100V. The reason they do it is that lower input voltages put more stress on APFC stage which is already massive and it's not economically viable to beefen it up even more for the handful of countries using input voltage below 115V (Japan and some countries in Central and South America). For example, basically the only direct competitor to AX1600i - Super Flower Leadex Gold/Platinum/Titanium 1600W and it's rebrand - EVGA G2/P2/T2 1600W are both rated for 115-240V, i.e they don't claim working capacity under 115V at all. Even if technically, just as AX1600i they would work without a hitch if the ambient temperature is low enough, they just can't be sure that it's safe as they wasn't designed to be operated as such.

As of OP's question, it's obviously not 230V only unit, 120V is completely safe, at full capacity.

PS: Also, if it's CP-9020183-CN, - that's a unit for Chinese market (even if it came with non-Chinese plug as these can be just dropped in by distributor), they use 220V only, so they probably didn't even bother putting derated wattage on the label, although internally it should be identical to worldwide version, at least i fully expect it to be.

That says 100-240, his says 200-220. Is there 2 different versions?

Don't use it. The seller either is lying, or mistaken. Or maybe there are some places in Canada that use 200 to 240VAC. I don't know. Either way, if your home uses 110 - 120VAC, don't use that PSU. It is not worth the risk.

"IF" that supply does support 120VAC, why doesn't the label say so? Corsair sells millions of PSUs around the world, including millions to here in the US, Canada (at least most of Canada) and most of South America too, where 110 - 120VAC is standard. They know how to properly label a PSU - a safety code requirement in almost every developed country, BTW.

So let's assume there was a factory mix up and it was mislabeled. That could happen. But that would cause me to wonder what other mix up happened with that PSU? Did that production assembly run even go through ANY quality assurance testing before leaving the factory? Why wasn't the mislabeling detected before it left the factory? They could have easily pulled those PSUs aside and attach a new, proper label.

Would you trust it will not burn up and/or take out all your expensive connected components? I sure wouldn't - at least not, as a trained electronics technician, I used proper PSU test equipment (most typical multimeters are not good enough!) to verify all output voltages and current demands were correct - and that is only if I already opened the package and ruined any "no questions asked" returned policies.

@Tigger - your link goes to a different power supply - check the model numbers. Yours is similar, but still different.

 

[chr0nos]

Plug that PSU into the mains, bridge the 24 pin so it turns on, Watch the fireworks (if any )

Then return to (probably) lying seller as defective

 

[newtekie1]

Not that I'm aware, they just revised the sticker to show that the unit is derated at lower voltages.

handful of countries using input voltage below 115V (Japan and some countries in Central and South America).

And the US. We are supposed to have 120v, but a lot of places get as low as 110v.

 

[juular]

So i've asked Jon (Corsair PSU dept. head).

 

[Shrek]

Is the extra cable they supplied sufficient for 13A?

 

[eidairaman1]

You would need a dual phase outlet to run that psu, single phase is no go
