Upgrading from x99 to x299, will 1600w be more than plenty?

In that case your existing ups and circuit its plugged into should be good for the 9900k build right?

For sure, overkill for a 750w PSU build I think. I had intended on replacing the entire circuit run with the 20 or 30A wire though so I don't need to cut the drywall and add another outlet box.

Is this a first floor or second floor location, should be able to install a new outlet in the existing wall that will be dedicated to the purpose of supplying the new pc. Keep existing circuit just was it is.

1600 Watt PSU isn't going to pull much more than 1800 at the wall, barely need to go to 20 A unless you intend to properly smash some power virus loads on the system.

 

If 1600 is a little over-sized for the system already I would just stick to whats there, get the 1600i instead of a 1600 G2 to reduce the at the wall pull juuuust in case and leave it. If you can make sure to give the PC its own circuit its not going to be an issue but I tell people not to use outlets for the circuit the PC is on anyways as many appliances send all sorts of nasty stuff back over the neutral and pull down the live when they get turned on.

 

Yeah I am planning to run a new circuit just for this rig (it's relatively easy to access via the attic - breaker panel is ~ 12 feet away in the same room). 

Since the current 1500 VA UPS was already inadequate for the previous 1200w PSU, and this new rig has a bit higher potential draw I put an AX1600i PSU in and am just debating options for how big of a circuit to run.

Basically I can save about $250 if I buy a 2200VA UPS (running on a 20 amp line) over a 3000VA model on a 30 amp line - with the only reservation being that I wanted to put another smaller rig (9900k + Titan V with a 750w PSU) on the same UPS if reasonably doable.

First-ish, it was a deck originally but they made it into an addition instead. There is a fair amount of attic space above and the breaker panel is in the same room so running a new circuit is not particularly difficult. I need to climb up there again anyway to run a glass TOSLink cable one of these days since the cheaper plastic ones keep melting during summer...

If you're just gonna send it as the kids say I'd just go for 220V setup, you get even better efficiency and grab 220V UPS (which isnt as bad as you think) for the setup and you dont worry since 20A 220V is what ?  Almost 5kW?? No need for monster 10 gauge and bulky 30A receptacles

Keeping the 2 rigs completely separate from each other will help with the chances/minimize the quantity of possible noise or interference the two systems could create and in turn have to deal with. 2200va for big rig,  1500va for the smaller one, 2 different circuits.

Very good point sir - thank you. I just ordered the 2200va, that does make the most sense.

Could I hit you with 1 more question? I've been wondering why the UPS connected to my new 1-outlet 20 amp circuit always reads 3-4 volts lower than the one connected to the existing 15 amp circuit with other things on it. Should this worry me at all?

I would have expected it to read higher if anything, since it is a shorter run of thicker gauge wire with nothing else putting a load on the same run but idk if it matters at all. Example, right now the 20A dedicated one is showing 118-119v but the other one is showing 122v.
