Hi my psu supports 1600 watts and my home circuit breaker is 125amps.

My question is ... how much is 1600 watts in amps?  i dont want to trip my home circuit breaker.

Depends on the voltage

I think the hoomans put their builds here?

Why do you hoomans give your builds a name? Here's my build, which I shall call "Do as I Say, Not As I Do" (seriously, don't get this build)

Spoiler

Ryzen 1500X @3,925 GHz

Cooler Master Hyper 212 Evo + 2x ML120

MSI B350 Tomahawk Arctic

2x8GB Corsair Vengeance LPX 3000 MHz CL15 (Micron B-die) @2933 MHz

Sapphire Radeon R9 280 Dual-X @1120 MHz / 1450 MHz

120GB 850 Evo

120GB Kingston SSD

500GB WD Blue

Cooler Master Elite 430

Seasonic Prime Titanium 650W

Logitech G710 with Kailh Box Jade

Logitech G502

HyperX Cloud

And my laptop, which I shall call "If It's Stupid But It Works" (It can actually play CS:GO at 50 FPS, and Civ V at 25 FPS)

Spoiler

Lenovo Thinkpad L460

Intel Core i3 6100U

4GB (probably) DDR4 2133 MHz

Intel HD Graphics 520 0.3-1.0 GHz

128GB Samsung MZ7LF128HCHP

Corsair M65 Pro RGB (worst mouse I've ever had)

Sennheiser CX 5.00G

And here would be where I would put a picture of my cat. But apparently, images are not allowed here. So take this instead (*ΦωΦ*)

What is your PC build?  Unless you're running a server, I doubt you're using more than 400W at load.

The voltage in the mains electricity?

Look at table of mains voltage and frequency, residential voltage, and find your country.

If you live in the US, your home voltage will be 110-120 volts. If you live in the UK or EU it'll be around 230.

 

At full 1600W load your psu will be pulling around 1800W from the wall in the US or 1750 in the UK/EU. That is 15-16 amps in the US, or around 7.5 in the UK/EU.

 

This is assuming you actually have 1600W load. You'll have a very hard time finding a system capable of pulling that much wattage, so your actual figures will be much lower. There's absolutely zero chance of you tripping a 125A breaker even if you push this psu to the max.

North America, some of South America, Japan and a few other places use around 110V, everywhere else uses around 220V-240V (basically).

 

If we assume your PSU is 100% efficient (which it's not, but we don't know how efficient your PSU is), you'd be using 14.45A @ 110V or 6.95A @230V. That's at a 1600W load BTW, which I seriously doubt will happen. 

 

If you account for the inefficiency of your PSU, the amps will go up a bit, but not by much.

Wattage=voltage*amperage

Assuming you live in the US, the voltage of your outlets should  be ~120v.  Flipping that formula around we see that wattage/voltage=amperage so 1600/120=13.3amperes.  Note you will likely never come ANYWHERE close to 1600watts unless you have some rediculous pc. 


Core i5-6600k OCed to 4.7GHz@1.325V | Hyper 212 Evo | ASUS GTX 1070 Strix ASUS z170-AR MOBO | 16GB DDR4@2400MHz | 500GB 850 EVO SSD | 1TB WD HDD | EVGA 650W G2 PSU | HyperX Cloud II Headset | Corsair K65 PRO RGB Mouse | Corsair STRAFE Brown Keyswitch Mechanical Keyboard |

A 1600w PSU on a 110v line will only draw about 18 amps from the wall after adding in a 20% fudge factor. Hopefully you will never come anywhere close to this.
