do i Need a better psu??

[doestilvoort]

Sup guys,

i think i need a better psu because i did that calculator thing on website, and it said that i had 720w consuming.

My setup:

Case: Haf X

Psu: zalman 750w plus

I5-2500k (overclocked to 4.5)

msi z77a g55

12 gb corsair vengeance ram

2x msi 660 ti pe

corsair h110

3: 200mm fans

1: 230mm fan

3: 140mm high performance fans

fancontroller

nzxt ledstrip + controller

cardreader

dvdr-cd

1: 128ssd

2: 500gb hdd

keyboard: logitech g19

mouse: roccat kone+

headset: corsair vengeance 2000

1 monitor: asus vg278hr

1 monitor samsung syncmaster s24b300

Creative sound 2:1

This is a calculator from Cooler Master which I personally use....: http://www.coolermaster.outervision.com/

 

 

I havent filled in your specs but just looking at it 750w should be fine... 

 

Is your PSU fan running loud because its under a lot of load? Does it seem to struggle in any way?

Those sites tend to overestimate. Your psu is plenty.

Just as a side note, additional wattage doesn't necessarily mean a "better" PSU.

Are you planning to overclock anything? I think for a non-oc system you are perfectly fine, but if you plan to OC the CPU and both GPU's you might run into issues. For example, at stock GPU clock, the Rig in my sig pulls maybe 450-470 watts in a game. With the overclock my GPU is running in the sig, it will EASILY pull 550 watts! I think it is just turning watts into heat  :blink:

You might be close, but if you have run prime 95 and furmark at the same time and you didn't have an issue, it probably isn't a purely power wattage issue as prime and furmark will pull WAY more volts than any game can.

but aside from the fact that it isnt a power issue.

isnt it beter to have more room for the psu then be on the limit evety time?

And after time the psu looses somebit of its power right? ( correct me if i am wrong?)

[doestilvoort]

Anyone can confirm my last post?

you have it man. with your rig you can get away with a good 650W unit and still have 150W not used

[LIGISTX]

Yes, you don't want to be too close to the max wattage of your PSU, but your system shouldn't be close. Only when running prime 95 + furmark would it even be a worry, but running both of those programs at once will draw significantly more power than any actual game or program ever will. I don't think even with both those programs running you are drawing more than ~650 watts.

Though your running a Geforce 400 series card, those things sucked down power like a person in a water chugging contest XD.

164wDC during furmark. Or 328w for two.

 

With an SB setup, your 750w would power it easily.
