Is 650W enough for water cooling?

[MX5J6]

I want to have a dual rad water cooling system so how much power will i need? More than 650W?

These are the rest of the specs in case anyone needs to know. I was looking at the Corsair TX650 so would that be enough or wouldI need more power? Also if you want to suggest another PSU please be sure it has 8 molex connectors, I will need them for all the fans.

Was also looking at the PCP and Cooling Silencer MkII 750W.

OS: Windows 7 Home Premium 64-Bit OEM
MoBo: ASUS Maximus V Gene
RAM: Corsair Vengeance LP Black 8GB (2 x 4GB) 1600
CPU: Intel Core i5-3570K Ivy Bridge 3.4GHz Quad-Core
HSF: COOLER MASTER Hyper 212 EVO (until I upgrade to water cooling)
GPU: MSI NVIDIA GeForce GTX 670 PE OC 2GB
SSD: SAMSUNG 830 Series 128GB
HDD: SAMSUNG Spinpoint F3 1TB 7200RPM
ODD: ASUS DVD Burner OEM

Water cooling at most will consume ~20W of juice. Based on the specs you posted you should be in the clear with a 650w PSU. Given WC will give you the ability to OC higher which will pull more juice, I still dont see that setup exceeding 650...

Thanks, just what I needed to know. =]

Well I'd say more 50w than 20w if using 5 fans and a powerful pump(5x5w+20w), but as SsjWizard says you have more than enough juice.

Well the case I will be using will have 10 rad fans and 4 case fans so 14 fans all together. Still enough juice? I am planning on using the 750 but if 650 will suffice then I can do that too.

Triple rad up top in push pull and a dual rad on the bottom in push pull so thats 10 rad fans, the SWITCH 810 will have 1 rear fan, 2 fron intake fans and 1 interior intake fan on the upper HDD cage. the botton one will be removed for the rad.

your CPU 77W design, your GPU 170W design, MOBO + accessories < 30W, add in another 10 fans at ~10W each and thats another 100W, so that puts you in the ~400W range not counting HDD/SSD/OOD and USB devices. Id say your pretty safe with a QUALITY 650W PSU even with 40% overclocks your only looking at ~550W...

Wow that surprises me a little. I think the Corsair TX650 should do just fine then, thanks. =]

EDIT: with the heat load of a 3770k and a 670, I really don't believe that you need a push/pull setup: 5.120 will give you a very good delta (4/5°C at full load) with a push config and fans running at medium speed (almost no noise).

Adding the pull fans will give you , at best, a 1 or 2°C drop. Not worth it in my opinion...
