Is corsair builder cx-500 any good?

Worrying about quality issues, mainly. Cheap stuff raises some flags for me. If the quality isn't good enough, what other 80+ Bronze PSU units for 450W are there around that will be good enough under $50 - 60 or so?

My aunt wanted a discrete GPU in the pc I built her so I offered my used GTX 640 and a CX-500 (She doesn't game of course so I don't want to spend too much on fancy stuff)

Thanks for any advice.
 
Solution
Get the CX450M, much better. There's zero reason to get an old design over a much newer and improved one. In addition, the CX non-M series is soon going to get completely new units also.
