1500W too much?

[PCnooberson]

Been saving up for this for a long time, and im going to be making a "dream build" essentially where i just go overkill on everything, possibly overclock, and am going to have 2 loops in the system.

I know wattage usage is almost always lower than you would expect, but with the internals maxed out, and with the custom cooling that would amount to 2 pumps and 15 or maybe even 20 fans, accessory lighting, and anything else im forgetting off the top of my head, is 1200 watts still good enough?

What circumstances would warrent a 1500w PSU?

Please list full specs. I can't tell you wattage without knowing what's consuming said wattage.

Plan is:

2 GTX 1080 OC
i7-6850k OC
Asus Rampage v Edition 10
64gb DDr4 3200 Ram
samsung 960 evo m.2 1tb
5TB 7200rpm hdd (1)
Possible blu ray player
2 mcp655 pumps
20 corsair sp120 fans
accessory lighting

dont know if fan controllers, keyboard/mice, headset use much if any wattage

i think thats about all

A good 850w would do it for stock clocks, a good 1000w unit will be more than plenty for overclocking.

Compare my recommended 1KW PSUs for overclocking rigs.

So the extra wattage of multiple pumps and irregularly high number of fans doesnt risk going over a 1200W PSU?
What circumstances would warrant a 1500W PSU?

2x 1080's: 360W, say 450W if overclocked
6850k: 140w, say 200W if overclocked
Everything else uses a negligible amount of power (<100W total), so I would say any high quality 800w+ is more than enough.

Only thing I can think of is a mining rig with 8xGTX 1080's, or something that uses a massive amount of power, either CPU or GPU. Fans and Pumps use very little power, the only things you should be worried about are GPU+CPU consumption and add around 200-300W to that to be on the safe side

If you wanted to run two R9 295X2 (dual GPU) cards, then I could see the need for a 1.5KW power supply... Other than that, not really.

MY apologies to the forum. I pressed that big green button instead of reply.

Why not cut back to normal in other areas and choose the 6950x?

This being a "dream build", the last thing i want to do is cut back on anything. But saying that, if im not going to need 1500w, no point in wasting money on it

Most of my specs are listed below san's some drive stuff which I'll list here:
2 Seagate 500gb HDD's in raid 0(my non-steam games)
1 6gb white label
1 3gb seagate
1 blu-ray burner/player

So all of that plus what I listed adds up to about 400-550watts during heavy load according to my UPS. The general rule I've read on many sites is to have a PSU that's about double what you use. This is because most PSU's are at their optimal during half load. That being said a 1000w or less should be fine. 850w will do it but heavy use might push you slightly past that sweet spot. Really you want to obsess on the quality. The corsairs I use are good enough but there are some that are better. Just try to keep to gold/platinum/titanium 80+. Reliable, stable, clean power can mean a lot to a stable system and it sticking around for a while. Modular is definitely the way to go as well.

Reason i make the thread and ask is because i already own a 1200i corsair PSU, and wanted to know if it would be sufficient for my case

I'd stick with it. That's what mine is for my 1080 SLI build. I've had no complaints. The system is very happy. I'm using a 1000i on my other build. Overall I'm really happy with Corsair but I've read some extremely technical reviews where they pass the heaviest tests in their tiers but only just barely.

The cards hold stable at stock out of box settings(I haven't even set up the gigabyte software) with 1.9-2.1ghz speeds while staying under 65c at heaviest and 60c average. When I'm able to game, its usually 6-10 hour session and the 1200i rocks it every time.

With all my drives, the 2x8pin connectors that each card uses, I've used most of the ports on the PSU but there's still a few left.
