Wrong PSU shipped - Should I still use?

[Zunti]

EVGA Supernova 750 G3 was ordered, but I received a 1000 watt instead (Received it for the price of the 750, not sure why).

 

The 750 would be more than enough power for my current build. Should I wait until I can get the 750 watt, or will it be fine for me to just throw the 1000 watt in the rig? 

 

I build my own PC's, but there seems to be a lot of noise on whether using an overkill PSU is fine or not. Honestly, I don't care a whole lot about efficiency, I just want my PC to turn on when I press the power button

It would be helpful to know your full spec list to help us deciding whether using 1000w is too much or not.

having extra wont hurt you at all.

 

 id just use the 1000 if it doesnt cost extra.

Contact the company and inform them of their mistake. Then decide from there.

If they want it back, do that. If they let you keep it, just use it. It can't hurt.

Having too much as far as PSU capabilities won't hurt anything. Your PC will pull what it needs.

Being this was from EVGA, it could have been they didn't have the 750 in stock so gave you a free upgrade to a better PSU. This is their MO which is why people choose them over other companies. Their support is TOP notch.

Inform evga and keep it if they let you. Overkill psu doesn’t hurt and the fan will spin less often Which should yield lower noise

no, higher wattage PSU could be louder when the fan starts.

 

and AFAIR that is the case with this unit.

 

With a 750W you might have like 300rpm less under normal/light loads...

I'd roll with it. EVGA PSUs are hella nice.

Not all of them, though. And the G3 is hella loud.

When dealing with electricity whether it is AC or DC voltage, sometimes things can get screwy but they really are not too difficult to deal with if you know a couple of things.  I have to apologize in advance because sometimes, for me anyway, it is easier for me to use examples so if my note gets long winded, I apologize in advance.

 

Generally, if an item (psu for example) is rated at 110 volts and 10 amps it will not hurt it if you hook it up to 50 volts and 10 amps.  It just won't work worth a darn because the voltage is not high enough but the amps is okay.  But....  (always have to have a but)...

 

If you hook up an item (psu again) rated at 110 volts and 10 amps to the wall and get 220 volts at 10 amps, then it will smoke.  The 10 amps is okay but the voltage is too high (obviously).

 

Amps is different.

 

If you take an item (psu again) rated at 110 volts and 10 amps and plug it into the wall and get 110 volts with 5 amps, then it probably won't work right either.  The voltage is okay but there is not enough Amps to push the voltage, the psu ends up under-powered and as a result it will most likely not behave the way it should.  Amperage (Amps is sorta goofy in a way).   But......  (again the but)

 

If you take your item (psu again, it gets around), rated at 110 volts and 10 amps and connect it to the wall rated at 110 volts and 20 amps, you won't have any problems at all and everything will work just fine.

 

Amperage is kind of funky in that if an item is rated at 10 amps and gets less than 10, then it goes funky with undetermined results.  But if you take that same item rated at 10 amps and hook it up to a 20 amp source, then that item (psu) will only take (use) what it needs.  It will just take the 10 it needs and it will disregard everything over that number.

 

I'm sorry that my response is so long winded but this is the only way that I could try to figure to use so that I could "hopefully" explain it in such a way that it wouldn't be hard to understand.

 

Hope this helps, when it was explained to me this way, oh so many years ago, it really helped me a lot.

just use a 1000w one, having more powerfull psu does not have any inpact on your rig niether on power consumption from the wall

Does the receipt that shipped with it show they swapped it with the higher wattage counterpart (1000W part on the receipt)?

 

If they didn't send it on purpose, not on the shipping receipt, I would email them, explain what you ordered vs what was received and ask if you could go ahead and keep the better one vs them having to pay return shipping and shipping the correct part.

 

The reason you want something from them in writing is in case you need warranty support since your receipt and product wouldn't match up when making a claim.
