This computer shares power with the living room entertainment, which is a Sharp Aquos 46 inch LCD, a Kenwood KAM-1 high current 5.1 receiver with NO SUB, an XBox 360, Sony Blu-ray player, and Nintendo Wii.
On the old TV, the circuit breaker (paired 15A 120V USA standard, 30A total allowance) had no issue with the computer at full load (CPU and GPUs operating mining operations). However, according to logs the RM1000 PSU was drawing 1073W (73 over the rating) which ended up burning a power cable and the PSU over several months. I upgraded to the AX1500i PSU, which can handle a slightly lower 1065W draw (due to the platinum rating of the new PSU, having higher efficiency), yet if the entertainment center is turned on the circuit breakers will trip.
The wattage draw measured by both the Corsair Link software via the PC and a separate ammeter module are almost identical. My confusion is that the newer PSU is more efficient, yet is causing this power issue. Even starting a game title that initiates both GPUs (Crossfire) is enough to trip the breakers after a few seconds. The rental office just says that we are overloading the circuit and refuses to get an electrician involved.
What’s going on?
Problem figured out.
Even though the PSU is running far under the 15A peak, the anti-ripple construction does actually hit 15A for microseconds before dropping to the specified load. Normally, the circuit breaker wouldn’t ever notice, but with the other load it is enough to slowly push towards a perceived overload. With an extension cord, I’m now drawing from the dining room (same room, just on the far other side) circuit and no more overloads.
I guess I didn’t read up enough! This PSU is the ultimate beast!
i’m not a electrician but i think that the sudden load then lesser but constant load maybe triggering the breaker, you have a 1600w psu so 1600w = 120 x I (I= amp) so 1600/120 = 13.33 amp + the tv, etc…
i’m basing this on my automotive mechanics class so i’m not sure about all that but i do resolve my problem of a pc with 1000w and a server with 800w power supply on the same breaker (living room) using an UPS resolve the problem, the sudden load is absorbed by the battery and not the breaker…
Maybe you want to try that, if that doesn’t resolve your issue, i’m sorry but i’m not able to do more 🙁 Good Luck !!
sorry double post 😛
I had a similar problem once. The circuit breaker would pop off during my gaming hours. I figured out other heavy devices shared that line. I’m currently using a 10 Gauge Extra Heavy Duty extension cable. Whatever it takes to work! 🙂
That’s what I have, now. Just a hidden 10Ga extension cable. No other option, unless I want to spend some big bucks on a true sine-wave UPS to act as a filter between the home circuit and the PC. Normal stepped wave or square wave UPS tend to not properly grasp the power bumps, and won’t properly isolate peak events. Plus, having a UPS beeping every few seconds when it DOES go over the wire peak doesn’t sound fun.
As far as otherwise, the AX1500i is an ABSOLUTE BEAST. With the CPU and both GPU’s at load, I can’t even make it warm up enough to turn the fan on. Just an absolute hotrod of a PSU.
