The older one should would in a pinch. But based on your specs, I would recommend buying a new one with about the same wattage as the one that "blew".
For only $19.99, the ePOWER ZU-400W
would be a nice choice. They are a good supply built by Topower which is an OEM manufacturer for brands such as Mushkin and OCZ.

Good point. I didn't even think of that angle.
