High pitched squeal (PSU?) when stress testing [Prime95]

[JOOK-D]

I've finally managed to get my CPU and RAM somewhat stable and once the Self-Test 1024K starts in Prime95 I get an extremely loud high pitched noise from the PSU. Originally I played it off as coil-whine which this PSU has always been plagued with, but I'm doubting whether that is it and if it's something more serious.

I'm getting mixed messages from another thread: http://www.tomshardware.co.uk/answers/id-1820125/high-pitched-noise-psu-stress-testing.html

The PSU is a Corsair TX650. I was planning on changing it out sometime soon for a fully modular PSU anyway, but do I need to do it immediately?

Any response is appreciated, thanks in advance.

A good working PSU will not make such noise, so it will be better if you replace it ASAP.

I would still say it's coil whine , just getting worse under prime 95 stress.

I would replace it , in the near future , it will only get worse.

Ok thanks. I'm now considering whether to continue the prime95 test, or just replace it right away with this http://uk.pcpartpicker.com/part/xfx-power-supply-p1650xxxb9

Is that a good choice? I was looking for fully modular but it seems I'll need to settle for semi.

Good choice , I would replace it as soon as possible.

And it's only £8 more... I guess I'll go for that. Thanks for the help.

It's a great PSU made by FSP , it's worth the extra £8 .
