Hello guys

I'm looking to change my old PSU dating back to 2009, it's a Sparkle 650w. It makes a lot of noises and it really pisses me off.

I want a real silent solution for doing simple talks like watching movies, browsing, listening to music and whatnot.

These 2 PSUs have come forward when I was looking for a silent solution.

AX 750 : http://www.newegg.ca/Product/Product.aspx?Item=N82E16817139016&Tpk=corsair%20ax%20750&IsVirtualParent=1

AX 760i : http://www.newegg.ca/Product/Product.aspx?Item=N82E16817139043

It's really not about saving power bills, it's just about noise.

Thanks

For a build like that a good 750w unit is more than enough.

Why should you get it? The fan doesn't even turn on until the PSU reaches a certain temperature (or was it load, either way it doesn't turn on) which ensures a quiet computing experience. Usually the loudest sound would come from you graphics card(s).

If you want complete silence I belive this will be the best choice from a best psu maker and strong enough to power your system in complete silence!

Edit: The later is strong enough that it can power A system with overclocked 3930k & GTX 660TI SLI !

Saying that : AX760i will be a good choice aswell speacialy if require high wattage and the fan in that not noisy or doesn't kick in when psu isn't stressed, so that's a nice choice aswell. I think you will be fine with any of them. Thanks



i7 4770k TDP 84 Watt
GTX 670 TDP 170 Watt x2 = 240 Watt
Others (HDD,Mobo,Fans,Lights,etc) Say another 60Watt
Lets Add another 100 Watt more for overclocking
Your Wattage requirements still doesnt exceed 500Watts!

You will be Fine with even a AX650 You simply dont have the most power hungry setup as you think you have. Latest Tech. is much more energy effecient then before.

Talking about electronics noise, Im sure your GTX670s will create most of the electronics and fan noise idle or load, so you can stop worrying about PSU Noise :) even the cpu if with watercooler still has a fan spinning!

Update:



Sorry for the typo mate :)
GTX 670 TDP 170 Watt x2 = 340 Watt
So your system can pull around 580 Watts Max.

Your idea and selection is correct in the sense its a 700+watt psu with platinum effeciency, that you don't want to stress the PSU to 80% load rather 50-60% load to increase life. I believe you will be fine with the AX760i which is also a platinum rated PSU one of the finest. Thanks

Seasonic OEMs for a lot of companies such as Corsair. I believe the AX 760i comes with Corsair Link and the non i doesn't. If you want a silent PSU then get what imomun suggested.
There is a 1000w Seasonic fanless PSU.... Anyways as long as you get a decent PSU with a quiet fan the PSU shouldn't be loud.

dudes, I'm probably gonna go Sli on Gtx 670s, with an overclocked Haswell i7 4770k, overclocked ram..2 hdds, 1 bluray, I don't think fanless is a good obtion, what I need is something totally quiet in idle and then it still is quiet when the system's stressed.

Plus while reading the reviews, some people say there're electronic noises, kinda sucks

Yeah right but I don't like the idea that it's always gonna stressed and that it might heat since it ain't got no fan
