Build Help Need help confirming I won’t blow up my electronics

Hello!

I just moved into a new place and my PC room only has 2 outlets close to my equipment. I want to buy a surge protector/power strip and was hoping someone could help confirm my math to ease my mind.

In quick summary, I will have my PC, 3 monitors, a desk lamp, & subwoofer + 2 speakers for now. I may add in an additional lamp as there are no ceiling lights. In total I estimate 1,150W at max draw.

Here’s a breakdown of where that’s coming from:

  1. [PSU PowerSpec PS 650BSM]: 650W max
  2. [Z623 Speaker System/Subwoofer]: 400W max
  3. [Acer VG270 sbmiipx]: 48W max
  4. [HP EliteDisplay E231]: 36W max
  5. [ASUS VG249q]: 16W max
  6. Arcadia Collection AF38651 Lamp: Depends on bulb (TBD)

Total = 1,150W (@110V this should be 10.45A max. I know 120V is standard but I prefer 110V when calculating current to give a little headroom.)

From my research, the Belkin 12-outlet 3,780J surge protector/power strip is very common, but I haven’t seen anyone push it up to 1,150W before. I know it’s still well below the 1,875W limit but I feel crazy plugging in so much stuff into one device, especially the subwoofer & PC.

Can anyone confirm I am calculating this right? Does anyone else draw >1,000W, and if so, what do you use as a surge protector/powerstrip?

Thanks for the support!

That setup will generally never be close to its peak wattage that you have listed. It should be a 15 amp breaker connecting those outlets. I prefer APC surge protectors but that's just me.

Agreed but I always like to assume the worst. I’ll have to double check what the rating is on the fuse box.

I totally understand that, but you would have to be listening to the audio system at max volume for an extended period of time and be running a CPU and GPU stress test as well. It's just not realistic. In other words, I'm just telling you it will be okay.

Haha you’re right, thank you for the peace of mind

The issue is what else do you have connected to the same circuit? There's very little chance that the circuit only has that one outlet connected to it.

Unfortunately I’m not sure what other outlets in the house are connected to this one. I assume I could flip the fuse’s one by one until I find the one for my room, and then see what else in the house doesn’t turn on.

That's a good plan.

Just remembered that there is an old fashioned fuse box (plug fuses) in the wall directly in that room with 2 20A & 2 15A fuse’s. I assume everything in my room is wired through there.
