Mostly it's okay, but it's save to check out for the cable diameter and current limits.

Most household power strips are rated for 1500 W at 120V maximum and are not rated for a continuous draw at that amount of power. If you use power strips, you should keep them at as fewer than 1000 W as possible. It's better to plug PSU's directly in to a wall outlet. Most household 120V 15A wall sockets will also get very warm when pulling over 1000W continously. Replacing the wall sockets with 20A sockets keeps them from heating up.

There are also 20A power strips, but they are expensive compared to the more common 15A household power strips.

Hi there,

So here are some issues with my rig. I got 2x 570 and 4x 480 on my rig using Calymore dual mining.

Dual mining is a lot power, is like 1 card and half.

you running at 120v? more current flow makes cord hot and even ambiet temp too
around 200w per amd card too much
try -mvddc 875 -cvddc 875 in claymore bat and set clock speed in claymore

check wire temp with ir thermometer, if below 45c no prob
amd more power consumption than Nvidia, undervolt amd using msi ab

Thanks for your reply.

it is more than 45c for sure. Maybe I should change a place to put the rig.

About the rig power consumption, I tried to undervolt and I do use msi ab. But once I use lower settings, the hashrate go down deeply like from 27 to 25 so I do not want to do it. I just want to know if this kind of power usage is normal.

Hi there,

So here are some issues with my rig. I got 2x 570 and 4x 480 on my rig using Calymore dual mining. The cpu is 1700x running at 3.8 for XMR.

I noticed that the power plug of the power strip is kind of hot. Not sure about the actual temp but it is hot. Is this a problem?

Also, the power comsumption reading from the wall is like 1120w. My another rig which has similar config except 5x 1070 only consume 820w on the wall. All the amd cards consume around 100w reading from afterburner. Is this normal or i need to do something about it.

Any suggestions would be very welcome.
