I am building a new rig, which will consist of a Ryzen 1600, 16gb DDR4, a GTX 1080, and a 1440p monitor. My power-supply, which I am unsure of at the moment, will be at least a 600 watt 80+ modular.

Here is what I would like to know. I live in a 5th wheel trailer rated 30 amps, and my old gaming rig did fine FX 4350, gtx 960 and a Corsair CX500, and a 27 inch 1080p monitor, but will the new system throw a breaker? I live in AZ and also run an RV ceiling AC in the day. I believe it may be a 1500 BTU? Not sure.

Sorry if my question sounds stupid, but I am not an electrically educated person.
 
Solution
FX 4350 -> 125 W
960 -> 120 W

Ryzen 1600 -> 65 W
GTX 1080 -> 180 W

Sum is the same, you should be fine. Do you want us to help you pick parts as well? 450W + good quality PSU will do :)

I will certainly take any recommendations, such as what is the best 1080 to buy.
Also, how much faster is the Ti version of the 1080, and wattage?
 
Yep, you'll be fine. I've helped bury and hook up more than a few RV electrical and water lines. Some of them we used a 50A breaker and others we used a 30A.I also know beyond the shadow of a doubt that your rig(HA!) both your rigs will be just fine with your setup. I'm also fairly certain you have breakers on the interior of your trailer as well which should trip before that trips.
 
1080 ti ~ 250W and ~$200+ more.
For 1440p 144Hz gaming, GTX 1080 is pretty good choice.
My recommendation (assuming reusing hdd with OS):

I hear good things about the MSI Armor 1080.

The Ti is about 35% faster. You're looking at about 70W more. Still your rig can handle right about 3500W total. Toss in a 20% buffer and that's about 2800W total. You then have to be aware of your interior breakers. You're still well within safety tolerances, taking into consideration there's probably also a monitor, speakers, a modem and possibly a router plugged into the same circuit.

Thanks for the list. I have already gotten my case in the mail, I will check out those other things you listed. I am ordering everything else in about a week.
 
A 15,000btu air conditioner generally runs at 15A but startup current should spike to 29A every time it cycles on.

You will have to determine exactly how much current it uses from the label on it before anyone can tell you if you have enough excess capacity on that 30A panel to run anything, unless you only want to be able to run the system at night when the A/C is off.
 


I am assuming he runs current rig and AC during summer, and new system have similar power consumption as current rig.
 
That is very logical, and means it shouldn't trip a breaker. Plus the CX-series is known to have a poor hold-up time as well, so just about any PSU would be better if voltage drops momentarily when the A/C switches on:
