Hi I am putting up my new rig! Choosing the right PSU is the dilemma.

Both of these are 650w, I was advised to go with 650 since crossfiring hd7850 wouldnt take much,they have good reviews and the antec one I believe is made by seasonic. I want to make full use of the July 4th sales on newegg.

Which of these would be the best? If yo can think of any other recommendations
from newegg that would be great as well

I am using these to crossfire the HD 7850 and oc I-3570K ivy bridge.

I am leaning towards the modular PSU, would choosing a non modular but well built PSU (corsair)
be a pain when it comes to managing cables in the corsair 300R?

Any inputs ?

They both have 2PCIE connectors, so you'll have to get a PSU with 4 PCIE connectors, otherwise, you'll only be able to use one of your 7850's.

Scratch that. 7850's have only one PCIE connector.

I would say the Corsair. However, maybe a 700w?

Any reasons as to why a 700w ? I believe the Hd 7850 TDP wattage is about 130w and I am using a 3570k
processor as well

The TDP of the 7xxx series is amazing. 650w is fine, I'd say.
