I am building a Peltier Cooler with the circuit diagram below. The power supply will be a battery, but for testing purposes I am connecting it to a stationary power supply.

I suspect that the peltier coolers which are rated at 30A will draw as much current and power as possible once I switch the power supply on, potentially destroying the supply itself even though I do not intend to deliver anything above 10 A. Are my fears warranted? I prefer not to try my luck as the power supply costs a fortune to replace.
Thanks in advance.
