I bought an Antec NeoEco 520C from newegg. I bought it for a system I was building but I didn't have all the parts yet. So I sent in the rebate without testing the unit (won't do that again). When I get the rest of the system and put it together the circuit breaker trips when I hit the power button. I throw the psu in another system and the same thing happens. I can't return it now since I sent the rebate, so I have to RMA (and I bought another PSU so I wouldn't have to wait).
The PSU comes back and I test it, the same thing happens (this is in a different PC than the ones I tested the first one in). I contact Antec again, they ask if it is plugged into a UPS, I reply no, they ask the amperage of the breaker and say it is unlikely that two psus have the same problem. I respond saying 15a and let them know 3 PCs all work fine on the breaker, noting that I tested their psu with everything on the breaker off. Their responses were taking <24hrs, now it has been a full week without hearing from them.
