Test for coil whine

[brshoemak]

Just picked up a Seasonic SSR-650RM (650W) from a deal online. I had heard that Seasonic PSUs can have issues with coil whine, but it was a great deal so I pulled the trigger.

I don't have the rest of my build ready (no MB, CPU, etc.) so I can't throw it into a system to test it.

If I short pins 4 and 6 with the ol' paper clip, will that be a good indication if coil whine is present or does it only occur when load is present? Thanks.

You need load, and sometimes only specific loads will resonate the coils.

Ok thanks. I'll need to figure something out then. I'll just call up my friend and borrow his desktop - that's what friends are for.

It can also be specific to various combinations of graphics card and PSU depending on how they resonate.

P95 blend test is making my PSU whine at times

Furmark + Prime95 at the same time, max load.

In my experience its usually occurs on menu screens of games. Super high FPS being cranked out.

Well I finally got the WAF high enough to pickup the rest of the build, so I overnighted everything and when it's together I'll hit it with Prime95 for awhile and see what happens.

This won't be a gaming PC, it will be an ESXi server. Of course, if a graphics card happened to show up at my door and somehow fell into a PCIe slot and if I just accidentally booted from a spare hard drive running Windows with Steam installed and a shortcut to Bioshock Infinite on the desktop - well things like that just happen from time to time and who am I to deny that sort of happenstance.

Furmark? Don't put a graphics card under such unnecessary torture. Just use Unigine or something.
