I have set my eyes on CORSAIR HX Series HX850 850W, and the cheapest one I could find is from NCIX.com for $149.99 with $10.00 rebate.
I was about to make my purchase before I discovered that this PSU has 2 models, older and current model. Amazon has both models listed, the model # for the older model is CMPSU-850HX and the model # for the newer model is simply HX850. PCPartPicker also have 2 models listed so I'm pretty sure it does come in 2 different models.
However, I simply cannot figure out which model the NCIX.com is selling. I love saving money (it's about $25.00 cheaper than newegg) but I don't want to end up paying for the old model, can anyone shed some light on this? Thanks!
