Should I get this power supply?

I'm building a gaming computer and I have decided to get the EVGA 141-BL-E757-TR LGA 1366 Intel X58 motherboard(http://www.newegg.com/Product/Product.aspx?Item=N82E16813188049&nm_mc=EMC-IGNEFL102709&cm_mmc=EMC-IGNEFL102709-_-MotherboardsIntel-_-LC1C-_-13188049) instead of the ASUS P6T on my list of components. This is because it is cheaper, and has more x16 slots(Which I liked because I wanted to at some point use 3-Way CrossFire or Quad-SLI. I was wondering if I should get this power supply: COOLER MASTER Real Power Pro1000 RS-A00-EMBA 1000W(http://www.newegg.com/Product/Product.aspx?Item=N82E16817171022). I thought I should get it because it would supply more power and has more 6-pin connectors than the other PSU I wanted. The list of components I planned on getting were here:

By the way, I like having room for overclocking and upgrading, making that another reason to buy the Cooler Master PSU

More about should power supply
  1. The Antec TP 750 will handle 2 graphics cards plus overclocking easily.

    That coolermaster is a older design, it has lots of 18 amp rails. It may have 6 PCIE power cables, but two of them are 8 pin which tells me it was designed for either twin 295s (requiring one 6 and one 8 pin each) or twin other GPUs (requiring two 6 pin connectors each) and is not really supposed to run 3 graphics cards. I would say calling this PSU 1000W is probably overrating it.

    I believe the Antec 750 is the superior power supply.

    If you think you want to go to three graphics cards, go for the Corsair 850TX PSU, it has six 6pin pcie power cables and more amperage where its needed (on the 12V rails) than that 1000W coolermaster.
  2. I wouldn't waste your money on that 1000W PSU. The TP-750 has plenty of power for your system even if you overclock and add another 5850 in crossfire. The 750W PSU is actually a higher quality unit as shown by its 80 PLUS BRONZE Certification.
  3. Thanks a lot! Both of your replies were very helpful! Like dndhatcher said, I should either keep my PSU or get the Corsair 850TX. I decided that if it is better than the Antec one I wanted, I should get it; plus, it's cheaper right now. I shouldn't pick a best answer, you were both just as helpful! :D
