Need new PSU after rebuild/overclock

I recently upgraded to a new case(HAF X) and got much better temps leading me to overclock my CPU, RAM and GPU and install new drives
Question: Is my current PSU powerful enough?

PSU: Antec TruePower 750 Blue

Config:
Core i5-2500k OC to 4.8 Ghz
Hyper 212 with push/pull
Radeon 6970 2GB Overclocked
16 GB (4x4) Patriot Viper Extreme OC to ~1670 Mhz
ASUS Sabertooth P67
HAF X Case with 4x 200mm fans, 3x 120mm fans, 1x 140mm fan, 1x 50mm fan
Asus DVD-RW
Asus BD-R
WD Caviar Black 2TB
Seagate Barracuda 3TB
Samsung 830 128GB
Crucial M4 64GB
OCZ Vertex 4 128GB
Sycthe Fan Controller
Creative Sound Blaster Titanium
D-Link 556 Wifi-N PCI Adapter


If not, please suggest a better PSU with CrossFire/Upgrade headway

Thanks

  1. That PSU is plenty, even for Crossfire.
  2. That PSU should be fine. It has 4 12v rails with 25a on each. There were several reviews by people with setups similar to yours saying they havent had any problems so far
  3. Wow, thanks for the quick reply guys. Just to be clear, this should be good even at full load? The so called 'online PSU calculators' estimate ~1000W at 100% load?

    1kW? WOW! No, that system should NEVER pull anywhere NEAR that, even with CF 6970's.

    I would say it's MUCH closer to 600-700W max at 100% load for EVERYTHING at the same time.

    1kW for THAT system, that's just insanely outrageous and idiotic, lol.
  5. Lol, thanks I guess we should all sue them :P

    I've read that they ain't entirely accurate

    Yeah, those things ALWAYS over estimate (not a bad thing, I suppose), but I can guarantee you that you won't be pulling anywhere near 1kW.
