Is 750watts enough for this?

[smokinAMD]

I finally put together a new PC about a week ago since it's been about 6 years since I've bought a new PC, it was time. Here's what I'm running with now, I don't see myself overclocking anytime soon unless I go to a different case where I could watercool it. I'm just concerned if I have a big enough power supply for what I'm using. This computer is pretty much going to be used for everything, watching and recording TV, gaming, video encoding, and data storage.

Motherboard: Asus M4A87TD-USB3
CPU: AMD Phenom IIx4 965 Black Edition
Video Card: XFX ATI HD5770 1GB DDR5
RAM: Corsair 4GB XMS3 1600 2GBx2 (2 sets for 8GB)
Main HD: Western Digital 750GB Sata 3.0 Black Edition (WD7501AALS)
Storage Drives: Seagate 2TB Sata 3.0 5900rpm (ST230005N4A1AS) (4 drives in Raid 5 for 6TB)
Optical Drive: LG 10x Blueray burner
TV tuner: Happauge HVR-250 MC PCI-E
Sound Card: Auzen X-Fi Prelude 7.1
Power Supply: Thermaltake TR2 RX750w
Case fans: I've got 4 sunon 80mm fans in my LianLi PC60 being controlled by a Nexus fan controller.

You could add two more 5770's to that setup and 750W would still be enough.

500 watts would be more than enough.

750W is enough, but that Thermaltake is not a 750W PSU: http://www.hardwaresecrets.com/article/Thermaltake-TR2-RX-750-W-Power-Supply-Review/902/7

It should still be fine since you aren't loading it much, but you should have asked here and gone with a better PSU instead.

You could pick up a Silencer 750W off of http://www.svc.com/ and it'll be enough for 3 5770s (don't know why'd you do that) for the low price of 70$.

the new Silencers pretty much suck too(for the price)....and cost much more than $70
