Power consumption of your equipment shouldn't cause this, there should be a circuit breaker that trips at a current draw below the maximum load of PDUs etc in order to protect them. I would be looking for a proper report from the datacentre/electricians into why this happened. Simply replacing failed power equipment without an investigation into what went wrong is not acceptable in this type of environment. I would be tempted to set everything to max performance and keep a close eye on it so that any failures will become clear more quickly, rather than happen randomly later at an inconvenient moment...
