Should I buy the EVGA G2 750 watt power supply earlier than my other parts?

[Aztec_Series]

I'm ordering all my parts Mid-February and I found this deal for my Power Supply. 80 dollars after mail in rebate for a 750 Watt Fully Modular PSU. Should I buy it now when the deal is still going on or should I wait? I'm afraid that the PSU will be DOA and the 30 day return policy won't cover it. Should I buy it risking that it might be DOA? This is my list for my PC.

Power supplies usually have a 5-7 year warranty on them. If you think the savings are substantial enough, then you should go ahead and get it now. I usually do the same and collect parts over a 2-3 week period when I find good deals.

Edit, when I checked out your config, I got a $101.99 price, so either NCIX hates me or the deal is gone.

Edit 2: But a lot of other, very high-quality PSUs remain on this list: http://pcpartpicker.com/parts/power-supply/#W=720,780&sort=a9&page=1&p=1,2&qq=1
