Thanks Q56, It's been Awhile since I've Built another "Monster" 4-Way SLI Rig!

That is amazing Halloween.  How many PSUs you need for that?  Great job.

Hallowen are you prepared for the event of the 1600W PSU not having enough juice for all 4 cards? It does seem possible to me @ approx. 400W per card of available power. Curious because I saw over on KPC a while back that TiN tested the 580's and found they can draw ~850W per card peak usage. Could be worth looking at putting one of the cards on the 1200 TT PSU instead.

It has a Rosewill Hercules 1600W Strictly for the Four KPE's and a Thermaltake Toughpower 1200W for the ASUS RIV BE Motherboard and 4930K CPU.

I Have All Three 8-Pin and Three 6-Pin Not being Used on the Thermaltake 1200W, So if I Need More Power for the KPE's, I can put One on that PSU.
 
Of Course if Push comes to Shove, I can Always Buy a Second Rosewill Hercules 1600W!
 
EDIT:
Come to Think of it, I WAS Having some Problems when I First Started Running the KPE's in 4-Way SLI because I Noticed that while I was running Vantage Benchmarks, My FPS all of a sudden was being Limited to 320 when I was Pushing the CPU and VC's.
It is VERY Possible that the KPE's are "Throttling" due to Not Enough Power!
 

It's Going to Be awhile before I can do any More Testing Since I have to Re-Load a Fresh Copy of Windows 7 X64.
 
I'll get back when it gets completed and I Finish the System Installation.
 
EDIT:
I ALSO have to Look for a SECOND Rosewill Hercules 1600W! 

Once I get my bench disk all perfect, I back up an image of the disk, so I never have to re-install windows.  I use the free version of macrium.  Use an e-sata cable to an external drive takes less than 3 minutes to back up or restore the image.  Even my larger drives that are over 200 gb full only take 16 mins to fully image.
