I hav Corsair VX550...i just bought a new rigg i.e
amd x6 1055t
2gb ddr3 corsair 1600mhz
but my mobo died when i connectd it to my psu.the hardware engineer said it was bcause the psu is too much for the PC...
too much current,etc,,,,,he said it is good only if the pc is working in crossfire....
IS it true??
I am no expert, but this explanation sounds extremely far fetched...
A.) 550W is not generally sufficient for Crossfire- unless you are using older cards.
B.) Many reviews do low load testing- and I believe PSUs are at peak efficiency ~ 60% of load, so 330W would be your peak efficiency level on this PSU... hard to imagine that a setup of Mobo, CPU, GPU, HDD, etc. cannot meet that number on a 550W.
idk, someone with my expertise than myself should chime in- but this sounds bogus to me.
