Is 750W enough?

[GirtMeister]

I have used online calculators that say this will work but I am not sure if 750W is enough for the following.

 

MSI Z77A-G45

Intel 2600K (OC 4.5 ghz)

MSI 660ti PE X2 (SLI)

Asus Xonar Essence STX

3 200mm fans

1 140mm fan

3 120mm fans

Corsair H100i

16 GB (4 dimms) of Kingston Hyper X at `1600Mhz

1TB WD Black

120GB OCZ Vertex 4

100GB WD HDD

 

Thanks!

Yes, it is enough.

[Godlygamer23]

Yes. You can get away with a 650 watt PSU if you wanted to.

[Dave :)]

Yes - you should be fine.

[UselessBread]

Yes. I have a similar setup (but only one 660Ti) and the HX750 by corsair. I took it because future SLI

Well i assume it will be fine.. go for it!

[911^NEmeSis]

Yeah seems all fine even for sli.

[virusal19]

Yes, 750W is more than enough to even run SLI 660 ti. You can get away with 500W if you do not plan on upgrading.

I just have to add on the 660ti to finish my build. Then I'll post it in the build logs :) It is looking pretty shweet.

Me too! I also have a similar setup on a 650w PSU with an i7 3770k and a GTX 670, and I havent had any problems.

Don't worry about it buddy. With a 750W PSU you still have about 70-80W of headroom in full load.

Evga recommends 450 watt for a 660 build so a 660ti shouldn't require more, even if it's SLI, manufacturers recommend more power because they know that people have shitty a power supply, so you're good
