Is this enough power for my build?

Hey guys, so this is my build, https://pcpartpicker.com/list/JyZ27W, and I have an 850 watt power supply. Everything combined seems very close to the limit, but the scrolling down, there are other parts whose power draw isn't accounted for. The three fans I am running, that aren't the corsair ones draw 15 watts together, so I definitely have at least 823 watts being drawn. I do not plan to upgrade after I have everything, I also do not intend to overclock. Should I be worried, or should I not, any help is appreciated. Thanks!

no, because the number on PCPartPicker you see is the maximum estimate wattage, if every part was at 100% load which won't happen in 99.9% of the time, and even if it does it is still below 850w.

For example, Ari Altman from Tech Buyer's Guru measured the power consumption of their 1080ti SLI + OC 6900k system (source), which PcPartPicker estimates a maximum of 774w.

Yet from the results it is found when the GPUs are not overclocked at a gaming load the system uses ~610W (672W from the wall times ~90.5% efficiency of power supply), and when the GPUs are overclocked ~680w is used.

Your power supply is fine.

Also, going selling your current card...

Thst is not enough power for wh a t is listed.
Just to put this out their that build as listed will not even work and looks like one of the worst builds I have ever seen.
5K for all that crap.

What are you going to be using that PC to do?

All the PCI-E cards will not even fit and your cramming all that into a 40 buck case.

EDIT you should mark anything you already have as purchased!!!!!

Seconding Zerk2012.

From the top of your parts list in bright red font:

"Warning: These parts have potential issues/incompatibilities. (See details.)"

Check the details and revise your build. Allow some extra power anyway. You may not plan to upgrade but things happen and then you also need to up the power.

Thanks for the response, I already have bought the PSU, and was just wondering if I had enough power. This PSU has served me well so far, but I would probably go for something from Seasonic, if this were to fail me.

I'll admit, I had wished I had gone for a more expensive case at the start, but ever since then I have been upgrading, and the components have served me well. Of course there are some down sides to a more budget oriented case, such as no 240 radiator support, but otherwise it works fine. Appearance wise, it isn't very strong, but through the use of modding, I have made the case look alright, and I plan on doing more. The PC part picker incompatibilities aren't relevant, as the Kaby Lake Processor I'm using works fine on the board, I have a SATA card for my drives, and the case DOES actually have mounting space for a second SSD. In fact, I am typing with this PC as we speak, and it does indeed work. You're right, the build isn't the best for the money, but I'm trying to make do with what I have. I have updated all the parts as purchased, https://pcpartpicker.com/list/kNkwhy. As for what I plan to do with this PC, well I'm obviously gaming, but I'm also video editing, graphic designing, music producing, digital art, video game code, website design, 3D modeling, and photo editing. Thanks for the response, and yes, I took the measurements, everything does fit.

Thanks for the response. The incompatibilities aren't a problem, as I have already taken care of them, one of them is incorrect, and I have purchased products, to make everything work together. I am not building this PC, ground up, but am instead upgrading my current PC. I have updated my build to show everything that I have currently purchased, https://pcpartpicker.com/list/kNkwhy.

Your power supply is fine.

Also, going selling your current card and purchasing a single, stronger card in the future is generally recommended over SLI configurations.

Thanks for the response! I'm going to go with what you said, because you have the accurate statistics to back your claim, though, the build you linked has less parts than my build. The only card I am thinking to upgrade to would be a Titan XP, but then again, the performance jump would not be that great compared to SLI 1080 TI's. Would there be any software I can use to monitor my total system power draw? I again am willing to take your word, and drop the money for a second 1080 ti, but I want to see the power draw before I do. Thanks.

No, because your power supply isn't sending information about the power consumption. You'd need to use a Kill a Watt or alike which can be bought for $20+ USD.

though, the build you linked has less parts than my build.

The CPU and GPU are the biggest consumers. The CPU they use consumes about 26w more than the i5 7600k (OC 6900k uses 4.5w more than 7700k, and the 7700k uses 21.5w more than the i5 7600k at gaming loads).

Let's say the hard drives are consuming about 10w at load if for some reason they were all at load, that's 40w more your system draws. And the rest of your parts that the review doesn't have would at best add to 10w.

So your system would only draw about 24w more at a gaming load. Still not an issue.

First I never said anything about what PCpartspicker says will or will not work, I never look at that it is just a basic compatibility check and really is like a build a PC for dummies site.

The EVGA G2 power supply is just as good as the Corasir or Seasonic listed above so no reason to buy another brand.
