Power Supply Thermaltake TR2 W0070RUC vs. OCZ ModXStream Pro OCZ500MXS

I am trying to decide between these two power supplies.

I have a matx case.

Thermaltake TR2 W0070RUC 430W for $20.99 after rebate.

vs.

OCZ ModXStream Pro OCZ500MXSP 500W (modular) for $39.99 after rebate

Obviously, I would love to save the $ and use it towards RAM for my build.

But am not sure which one I should go for and if its worth the extra $20 for the modular one.

Now, one lingering problem I see is that the Thermaltake only has two sata connectors, yet I have three sata devices.

So that might rule itself out

would appreciate the input.

Thanks - amazing review - that is the PS that newegg is selling.

I'm looking for a great PSU at a great price, i know its hard, but so far i think the OCZ Modstream is the only one right now that fits that criteria.

The components I have so far are :

# GIGABYTE GA-G31M-ES2L matx motherboard
#PENTIUM DUAL-CORE E5200 2.5G (800MHz)

Combo cost me $106

# Apex Micro ATX Tower

Cost me $25

# Video Card with HDMI port

Cost me $15

Objective is to build a powerhouse PC at a budget price.

Any other PSU you all can recommend. Otherwise will just go with the OCZ.

Thanks for the info - yeah that is the same line i was thinking, except the one i listed is the 500W for $10 less.
