Need a power supply

:hello: Building a new gaming rig. Here are the specs:

CPU: AMD Phenom II X4 965
GPU: MSI N660 Ti PE 2GD5/OC GeForce GTX 660 Ti 2GB
RAM: G.SKILL Ripjaws X Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600
CASE: Rosewill BLACKHAWK Gaming ATX Mid Tower
HDD: Western Digital WD Black WD1002FAEX

I was thinking of getting this power supply, but not sure:
CORSAIR Enthusiast Series TX650

ASUS's power supply calculator says that I need 700w minimum. 5 fans, 3 devices being used by usb ports and u have the other info as posted above.

I would like to know how accurate their estimation of power usage is. Recommend me a reliable brand PSU that exceeds my needs, but is not overkill. Keep in mind that power usage UNDER LOAD is going to be much more than idle. Oh, and I only buy from newegg, so it has to be available there.

  1. You could probably run that system on a 600W or 500W.

    The TX650 should be fine.
  2. 700w sounds a bit off to me. Seasonic makes the best psus (and Corsair's better psus). I would go with this one
  3. Thanks for your input Deemo13 and maestro0428. As for anyone else reading this, I'm very interested to hear what you have to say! Please post!
  4. ASUS power supply calculator tends to overstate the PSU requirements. Try this PSU calculator instead: It's more accurate. Based on your post, it suggests about 435W is necessary so a 500W PSU would be adequate.
    CORSAIR Builder Series CX500
    SeaSonic S12II 520 Bronze 520W

    A good quality 550W for a single GPU is more than enough. Plus, 600 series cards are power efficient cards.

    This should do it: SeaSonic G Series 550W -
