The CX line isn't great, but on a really tight budget it is one of the best choices.
If you can manage just a little bit more this PSU is a high-quailty unit that has a terrific sale on right now for only $15 more than the CX. It is a much stronger unit:
Power Supply: EVGA 750W 80+ Bronze Certified Semi-Modular ATX Power Supply ($44.99 @ NCIX US)
Total: $44.99
Prices include shipping, taxes, and discounts when available
