HX.
The components and build quality are better, this is also why the HX has a 7 year warranty and the CSM a 5 year. For the $10 difference, the HX.
Here's a review of it slightly bigger brother:

The HX over the CS Series Modular.

The CS Series is missing the transient filtering stage and is only rated to deliver its full rated power at up to 40°C. Ripple levels are also higher and it falls short of the hold-up time in the ATX12V Power Supply Design Guide Specifications. It uses a cheaper sleeve bearing cooling fan. Bulk capacitors on the primary are only rated for 85°C. Cheaper Taiwanese electrolytic capacitors are used on the secondary.

The HX Series model is rated to deliver its full rated power at up to 50°C. Ripple levels are a lot lower. A ball bearing cooling fan is used for longer operating life. All of the electrolytic capacitors used on both the primary and secondary are Japanese and rated at 105°C.

The AX , AXi , HX , HXi are all decent power supplies.

The rest I won't recommend.
