Fan running at full speed

Morning all.
Been trying to track down the cause of my louder than it should be PC.
I always thought it was my ddc pump causing vibration on the case (even although I have it on rubber feet etc). Turned case fans off, turned radiator fans off, still loud. Never occurred to me to check the PSU.
So last night, finally tracked down the loudness to my PSU. Fans seem to be running at full pelt constantly, which also leads to a bit of case vibration.
It's an XFX 650 core edition. Really can't remember when I got it, but must be over 5 years at least.
Is there any way to check the fan speed for a PSU?
I know the inevitable answer is - get a new PSU :)
 
Except for few occasional PSU during the years with fan RPM output cable only way for knowing its RPM would be using some kind laser/optical detection using tachometer.

And certainly better failure for fan control to go to full speed than permanent zero.
 
650W is enough for those. (even 550W)
With that graphics card power draw would be around 300W in games.

So there's plenty of room from next-gen console multiplatter games to load CPU fully or say 50W higher draw GPU.

While it's true that in upper end power consumption can fast go to ridiculous numbers...
Like heavily OC'd CPU peak easily around 300W and also graphics fast exceed 300W, if you don't overclock and avoid (often expensive) worst power hog parts, power draw stays moderate.
 
Thanks.
Think I'll go with antec. Had good reviews and don't mind a few fixed cables, be using those ones anyway and can get them round back of the case
 
Gah, sorry to keep posting, reading reviews etc
I'm torn between 2 psu
Antec eag650 gold pro
Corsair rmx750 (which is on offer)

Can't find anything about fan orientation, but did see something on Tom's suggesting the corsair shouldn't be upside down? So in my case it would be pulling air from inside case rather than bottom/outside?
