Keep in mind, these are all no-name/off brands and while they would work as a stop-gap solution, I wouldn't chance a new expensive computer with one of these in the long term in case the next time one of these cheap ones dies, it takes the system with it.
That 600W one also has only 1 sata connector, no PCI-E power connectors, and only 24A on the +12V rail.
There's a bunch of big name PSUs on sale @ NCIX right now. An OCZ 650watter is only $59.
