I hope they sold you a good one - that board uses 5V power
for the CPU vcore subcircuit, meaning for best results
either an ATX 2.0 or older PSU, or a very high capacity and
high quality newer PSU design is needed. Otherwise, it's
likely to have another PSU failure. An honest combined
rating on the 3.3+5V rails of 200W, or more with a lot of
parts like (for it's time) higher end video card, is highly
preferred. A more conservative rating would be 230W+
combined rating for those rails, something even most modern
500W PSU don't provide, but was not uncommon on older
350-400W PSU.
