I have been having some issues with my PSU, over the past few months, I have switched 4 PSUs, all have had a coil whine (very bad) and other issues, loud fans etc.

 

I ended up on the Seasonic Platinium 760w, but it has the same issue. So now I want to replace it (while I wait for RMA) with the best option available.

 

I want the following

 

750W (700 minimum)

Quiet Fans (like the new RM series, though they are 180mm)

160mm max (I have a Bitfenix Phenom mITX)

Fully Modular

 

I am worried no matter what I get I will have the same issue, because 3 in a row is kinda weird, but my system seems to be fine. Options?

Three in a row is odd. Can you list all the components in your system? What PSU's have you tried?

Hi there try to avoid Seasonic and Corsair, as I've seen lots of reports from other forums about coil wine etc... That's why I bought a Thermaltake near silent unless you hammer the power and even then it's still quiet, also has flat modular cables.

This is the current setup. (yes I know I don't actually need 750W, but I am future proofing, I hope lol)

 

Case - BitFenix Phenom mITX
MOBO - Asus ROG Maximus VI Impact
CPU - Intel Core i7 4770K Haswel 3.5Ghz
RAM - G.SKILL 1866Mhz DDR3 16GB
Video - Nvidia Geforce GTX 770 2GB
SSD - Samsung 500GB
PSU - Seasonic Platinum 760W

 

I have tried two types of Corsair, and one Seasonic. I thought SeaSonic was high end, and made most of the other brands anyway?

Seasonic make the internals for Corsair PSUs now... So if an issue effects one also effects the other. Really annoying as I used to have a Corsair PSU... So recently changed It for a new one, and got the coil wine so I RMA'd it and changed it for a Thermaltake.

Which Thermaltake are you using? Though, none appear to be fully modular.

This one supposidly isn't made by SeaSonic but from someone else.

So, except for bad luck, is there anything to do with my system that could cause PSUs to have issues such as whine/noise?

 

I really need/want fully modular, so the Thermaltakes won't do. So I am willing to try another Corsair, or whatever, but obviously, it is weird that I have had this much issue. (and I have tried using a differnet plug into the wall)

I have a Corsair PSU and it is quiet and modular. It provides enough power for multiple GTX Titans. I've been really happy with it.

Sadly NO... the only way is to make sure it's one, not with SeaSonic parts inside. I have had similar problems with certain makes of graphics cards as well, with wine I ended up not using that make.

 

Inwin, OCZ, EVGA, Zalman, and Silverstone make some full modular PSUs.

Well I think I will try the linked Corsair above, as I read on a review its not Seasonic. I guess I will find out, see what happens.

That's a bit weird, is the machine running a bit on the hot side and/or your desktop is running on high power load constantly?  Or the PSUs you're getting not very efficient?  With most power-efficient PSU the fans hardly start up unless they're under high load or there's some sort of thermal issue.  Try to aim for something 80 Plus Platinum certified if possible.

 

If it matters, I've never really heard the Corsair AX860i in my system, seems pretty quiet.  (though my computer case is pretty quiet so maybe I'm biased).
