PSU With Lowest Ripple

[dabockster]

Hey all,

My two year old EVGA 650 GQ has some serious ripple going on. It's causing my GPU to coil whine and will sometimes even transfer the whine into my headphones. Since any RMA would leave me without my computer (I have a laptop, but otherwise that's it), I am forced to buy another power supply with less ripple.

So which PSUs have the least amount of ripple? I was looking at the Seasonic Focus Plus Gold line, but was wondering if anyone else had any suggestions.

Seasonic Prime Ultra Titanium but those are crazy expensive, but EVGA G2/G3 have decent ripple due to in-cable capacitors, the focus plus is good too.

In which universe do you live in, for you to reach that conclusion?

The newer Seasonic ones are best.

I posted in the GPU forum about it. Tried everything except replace the PSU or GPU. I figured the PSU was the culprit since that's the one part I haven't upgraded yet. My original system two years ago had a low end ASUS 1060 3GB in it that didn't draw much power/current.

Any model suggestions? I saw the Prime Ultra Titanium but was hoping for something a tad less expensive. Shooting for 850 watts.

Spoiler

The cable to the front panel headphone connector acts as an antenna. Just use the rear jack so you can get somewhat decent audio. The PSU's output ripple does not have anything to do with the EMI from the PSU or any other component in the PC.

You don't need 850W.

The Prime Ultra is basically the best you cna get right now.

The whole point of that post is that I don't want to use the rear jack for my headphones. I already use it for a set of speakers. I want to use the front jack.

If I start OCing stuff again I might. Or if I upgrade to the new Ryzen processor. Or do a custom loop. Trying to plan for the future a bit since I have the opportunity.

You don't need 850W for overclocking or Ryzen.

A custom loop does not use much power, it's literally just a few watts for a pump.

 

Unless you are running 3+ GPUs (which you should definitely never do) and some high power threadripper or xeon CPU, there's no need for more than 650-750W

Coilwhine transfered into the Headphones? Rofl.
