How much power do i need if i wan to OC too with this rig.

There are three coolers? See one CPU and one VGA?

750W will be fine, if you are running two cards then 850w will be good to go. Choose a reasonable make and not some no-name brand please.

To help us help you - please provide as much information about your system and the problem as possible.

hmm the PC shop has recommend Silverstone Strider Plus 600W (Full Modular). It is sufficient to OC too? The GPU cooler is mixed of Corsair Hydro H75 Liquid Cooling + NZXT Kraken G10 Bracket

Which store are you using? Do they have a website? Link me.

Yea don't listen to that store, just trust us, you'll be thanking us when your PSU doesn't burn up, although it would be enough if say you don't want to OC, but a PSU can also limit the amount of external devices you can use too, extra wattage is the best kind of wattage!!!

PcPartPicker.com got ahold of a steam box that was running a 450 watt PSU if i believe I'm correct, this was powering this hardware: http://pcpartpicker.com/p/2mxQ1

450w for a GTX 780..., 600w will probably be stable until you start overclocking.

CPU:i5 4670K @ 4.4Ghz stable at 1.2v
MOBO:Asus Maximus VI Hero LGA1150 Z87
RAM:G. Skill Ripjaws X 8gb (2x4gb modules) OC to 1866Mhz
GPU:TBA
PSU:EVGA Supernova 750 watt 80+ Gold
CPU Cooler:Corsair H80i, this thing is a beast for its size.
Case:Corsair 300r, not the best but good looking.
SSD:OCZ Vertex 4 128gb

I'd second the 750w....with a good rating for current (amps) on the 12v rail. For OCing the CPU and GPU and doing it in the comfort zone of the PSU. The PSU is the heart of the system. You want clean stable power from a good unit so get the best you can...Seasonic...Corsair AX series....

750W.
guys in the store aims for low wattage becouse they dont think the system uses that mutch.
bether whit headroom then sitting in a tight spot ( so to say ) when it comes to power and have no headroom to add tings in it.
and the cooling setup on the card bugs me, personaly i dislikes it but hey each to their own 🙂

LukeeVassallo · ‎01-26-2014

A decent brand power supply such as corsair, seasonic, pc power and cooling and others. Well I'd go with an 850W power supply, the gpu is quite heavy and will draw a lot of power. Also the psu is most efficient when the load is 40-60%.
Don't buy a cheap psu, it's as important as your processor and gpu!

Why are you getting the KRAKEN G10 bracket for that card? It does not get the VRM. Believe me, they get pretty warm! I have my cards core/vrm never EVER going over 38C EVER!!! but that's on full blown high end ($900+) water loop. You are likely better getting one with a non-reference cooler that actually gets the VRMs properly.

The below is my rig(2xSapphire Reference 290X on EK Water) running Unigine on ULTRA with extreme tesselation (x-fire is off right now). If it wasn't on water those temps would be a lot higher as the 290/290X are one of the hottest cards around. You absolutely do not want to burn you MOSFET/VRM section up!

CPU @ 4.4 @ 1.35vcore / 1.28 cache voltage
GPU: STOCK
Note: OPT1 Probe is my loop water temperature via a fitting inline.
