850w enough for this build?

[Omie]

Is an EVGA 850w G2 PSU enough for this build (assuming there is a significant overclock on the CPU and GPU)?:

I know PCPP says that approximately 410W is how much power it needs, but I just want to make sure.

 

And this is very unlikely to happen, but just in case, would the 850W G2 still be enough for another Strix 1080 OC edition to be added on, thus SLI 1080's (still assuming a significant overclock on the CPU and GPU's of course)?

[STRMfrmXMN]

850W would be more than fine for two 1080s.

[The Sloth]

yes and overkill it will work perfectly. 

[Energycore]

You could run that build on a CX450M, dunno why you wanna buy an 850W.

 

If you're gonna buy a really really high-end PSU, get my choice of RM750i. It works with Corsair Link software to let you customize its fan curve and switch it from single rail to multi rail operation if you like. It's also SLI capable.

[DarkBlade2117]

You're fine with a 550w TBH and 650w for SLI though 750w is preferred

Also... you don't need a $400 motherboard...

I think the H115i has had issues with loud pump noise.

Why a full tower case? Something like a Phanteks P400s imo will make for a much better build aesthetically wise.

Ok, even if the CPU and GPU's are both significantly overclocked?

 

(I just edited that put that info in my main post so I'm not sure if you saw it).

500W is plenty, you wouldn't need more than 750W for SLI 1080s.

I think almost all AIO pumps have had complaints with pump noise. I've researched and looked at lots of threads, but hopefully I get lucky with a good unit.

 

And I like the Enthoo Luxe cause I can Aura Sync it with the rest of my build.

Same can be said for the Phanteks P400 about Aura Sync <3 Imo I don't see the need for full towers unless you are actually going to fill up the space it has.

Ya lots of pumps are noisey but the H115i is one of the louder ones.

Hmm, louder compared to what other AIO's?

 

And this is going to be my first full tower but I like having more space. More space is always good IMO, better airflow and overall cooling.

Yes, a H115i is from Corsair so it gotta be noisy! i suggest another AIO, if your already wanting overkill a Predator 240

Well if you look in my build I'm actually replacing the stock fans of the H115i with 2x ML140 Pro's so I think I should be good with the noise level. Predator 240 looks cool but I just like the look of the Corsair block more, especially with the LED.

Idk about Corsair fans, but from what i heard they're noise af

 

I would get Noctuas over Corsair ANY DAY, even tho they don't have RGB (i don't know how big of a difference that makes to you) but for me its not a very big difference

 

But as again i said, i don't know how ML's perform

ML's are good. They have lots of good reviews on them and a lot of people actually replace their stock fans with them. I got the Red LED ones. Corsair doesn't offer RGB with their ML series though.

 

Noctuas are cool but I don't like their color and I want to have at least some LED to go with my build.

Overclocked 7700K draws about 130-140w(supposed similar to 6700K). An overclocked GTX1080 draw ~210-220W. Plus RAM, fans, SSD, HDD, pump, etc. Total power draw less than 450w.

 

And you doubt whether 850w is enough.....Unless you plan to 3-way SLI later.

Oh I see. I guess what confused me is that PCPP showed a usage of 410W but I wasn't sure if that includes OC's or not.

[Mick Naughty]

I'd go 800-850. Leave room for degradation as I assume you'll have most of these components for a long time. 

 

As long as it has the appropriate efficiency ratings at the corresponding usages you hit.
