no they are using 5 and splitting 2 into 4
so
1 single 18 gauge
1single 18 gauge
1 single 18 gauge
then a single 18 gauge that splits into 2 single 18gauge
then a single 18 gauge that splits into 2 single 18gauge
and every photo of every burnt setup shows the melt starts by the split cables.
I mention that this psu should not be used long term more then one time in my review and that I went to a rosewill tokamak 1500 watt with no issues
Yeah, that's completely irresponsible engineering right there. Too few conductors with too few connections to the hardware. And with wiring like that, I seriously question their "1600W" unit is capable of anywhere near that mark over the long haul. If it is, it's a fire hazard because the cabling simply can't support it.
Stuff like this sickens me. This crap is going to burn someone's house down.
FYI, those Tokamak units throw a ton of EMI back into the power lines. I just pulled one out of my farm because I couldn't review power supplies with it running at the same time. Too much extra noise in the oscilloscope. They kill AM radio for a block, too. I have another 1200W Enhance Titanium doing the same thing which will also come out of the farm soon. Other than that, they are good units. I'd have just kept using it if I wasn't a power supply reviewer, but I hate shutting the rigs down just for load testing so I'm migrating to units that don't do that.
Well, it seems that EMI seems to be the main possibility. After reading many of the posts, their are several complaints that point to EMI. One guy complained that he blew a capacitor, and the pictures show burning on the ground wires, not on the +12V wires and now we have somebody complaining that he's getting a lot of 'noise' from couple of his units. And if you go into the theory far enough, some experts claim that these frequencies are destructive in many ways and in many cases.
How to fix it or help it might be difficult. Some ways that might help would be to make the wires twisted pairs, which is hard to do unless you can make some fancy braiding by turning the plug back through the wire on itself a couple of times. Another method that should help is to wrap the cables with copper or aluminum foil for shielding. Steel foil will not be as good as aluminum or copper, with frequencies this high.
This frequency leak is what likely destroyed the capacitor too. The problem is magnified when you have 2 frequencies that in harmony with each other and the make it a multiplier. Another reason I think this might be the problem is because this box has the ability to do many different hashing speeds. If their is a frequency leak from two circuits and are in some kind of harmony, this will create another frequency. One or more of these frequencies seems to be destructive.
I'm guessing you don't have any bugs hanging around and no dogs. The frequency might drive them nuts. haha.
P.S. Did panda warrant the burned boards?
