PSU wattage help.

post #1 of 3
Thread Starter 
Hello everyone, I'm new here and need some advice on a PSU purchase, been asking around and getting a few opinions, and PSU calculators seem to vary. I'm building the following -

Formula VI MB
i7 4770k overclocked
16 GB RAM
Will eventually have dual 780 or 780ti's, also overclocked
2 HDD's
Front control panel, possibly two with the liquid cooling
< 10 LED case fans
Possibly 3 cold cathrodes
Closed loop custom water cooled system.

I hear 850 is enough, like the Thermaltake Toughpower 850. Others say 1000 is minimum, like the CoolerMaster V1000, or I could go with the EVGA supernova 1300.

I don't want to have overkill, but want to have enough, I also don't want to spend $400 on a PSU, so no Seasonic or Corsair 1200xi, especially when the V100 and the EVGA got excellent reviews on jonnyguru.com.

Opinions please?

A good quality 850 should be fine for that build. Let's put things in perspective.. Take a look at the rig in my signature (Click the down arrow). If I were to swap the 7970 for a 780ti the PSU I have would still be enough. Just barely, but it would be enough.

The first link on this page is the PSU calc alot of people go by. http://www.extreme.outervision.com/index.jsp

As for which PSU to get at that wattage? One of my friends has the Corsair RM 850 and loves it. Thats about $150.
