Is there any negative to buying a bigger power supply than you need

If I don’t fill out the wattage as much though will it really cause issues. I mean it should be running at about 500 right away but then as I tweak overclocking etc it will get to 650-700.

 

I just don’t want to have issues like it won’t cause any major malfunction by having it not utilize more of the power.

if you're running at 50% load it's fine

So I bought a 1000watt EVGA SuperNOVA p2 but after showing a few people they have told me I could have gone with a 750-850. Thing is if I return. It I get spanked with return shipping etc and restock fee probably. Is there any negative to having a bigger than needed psu if so what is it. I figure I probably will be using around 500-600 watts without major overclocking but I am watercooling so plan on pushing it a little. 

 

Plus 7 fans pump less etc.

 

I have done a few check and depending on how much I over click it could go to 1200 but I don’t think I will push it that far. 

 

Any info is appreciated.

For a regular gaming setup, there's no way you can consume anywhere near 1000 Watts. For a super high end gaming PC, an 850 Watt would still be a bit much. You do, however, have the headroom to get any side CPU and GPU you want without worrying about power draw, but low power loads on a highly rated supply can be very inconsistent.

I WILL find your ITX build thread, and I WILL recommend the SIlverstone Sugo SG13B

So I take it it's roughly a 7980XE and 2080 Ti you have? Based on the power draw?

 

Higher price, likely higher noise, bigger potential for damage in case of a catastrophic failure, and often larger PSU dimensions.

No, also I hope you didn't spend $250 on a psu if you didn't max your build.  Also 800w would in retrospect be plenty for watercooling.

I might not know what I'm talking about but I'm gonna say it anyways

Unless you get a G3, then they're the same size. And I have a 1000W G3, which is overkill even for my R7 2700X/1080 SLI setup, but it leaves me the option to get more power hungry hardware in the future (I'd love to get my hand on a pair of Vega 64s or FEs in the future).

I said often, not always ;)

Overclocked Vegas, I hope? With the 400W overclocked power limit, you can actually justify 1000W for just a mainstream platform and just two GPUs.

Heck yeah, if I had the cash for them. I may eventually sell my 1080s and put that towards some Vega cards, IDK. I'd want to get an Evolv X first though, right now I have the normal Evolv which is fine for my hardware, but AFAIK the Vegas are heat machines so I'd defo want more airflow than I need for my EVGA 1080 SCs.

I just checked your bio for the parts you use and it looks like with that 9900k you can at least start to justify the price tag, you'll just need to get a nice double rad and push the limit of your CPU. Overclock the crap out of your GPU too

I never want power to be an issue - so I run a Corsair HX850.  If a HX1000 was the same price, I would have gotten that instead.  Nothing wrong with a high power PSU, you just wont use it all.

Yea it’s not here yet but 9900k and a 2080ti msi trio so that alone is 400 watts than fans led radiator pump and no overclocking. I just don’t know what the restock fee and they want me to pay shipping even though I tried to cancel. So I wouldn’t be saving money but would it be better for my build is more my concern not the money.

That’s kinda how I felt as well because if the power supply lasts as long as it should I will be upgrading again and things only seem to get more power hungry.

Yeah but it's also not worth sending back if you fill out the wattage a bit more

You'll be fine. Even systems that can draw up to 1000w will still be around 100-300w when idle, so the PSU shouldn't have any issues delivering a lower wattage.

 

It really only hits your wallet in the premium price you pay for higher wattage units, as well as -depending on the unit- sometimes more aggressive fan curves resulting in a louder unit.

The unit should still function perfectly fine without any risk to your hardware.
