hi there,so from what you post your psu has a combined 12v rails of 34A * 12v = 408w that should be enough for that gpu, which has 19A for the 12v rail and a 450W psu minimum as a recommendation. the thing is dell psu arent quality units and even they seem capable there arent to be trusted. i would suggest a psu upgrade since your pc doesnt respond after the gpu installation.(make sure the gpu is securely inserted into the pcie slot)

Agreed. It might be that the amperage/rail was measured using only a single rail at a time, making the PSU seem more powerful than it actually is.
