Palit GTX 770 & PSU noise

I just bought a Palit GTX 770 and noticed the power supply was making a whining sound when playing games.

My power supply is a 4 year old Antec TruePower New Modular 750W '80 Plus Bronze'.

Is this psu struggling with the 770?

It may be capacitor whine from the GPU rather than the PSU. Can you swap back to your old card/onboard and see if the sound goes away?

If it is coming from the GPU sometimes it does stop happening once the card has been used for a while. On some games enabling vsync will also stop the whine - my Mrs plays the Sims 3 and it whines like a banshee until you switch vsync on.
 
Thanks for the reply. The 770 has replaced an ATI 5770 and this was silent.

I find the noise of this new card really annoying :(

If the noise is excessive then you could RMA it and get a replacement. Coil whine is present on quite a lot of cards these days... Some loud and some very quiet. I've had a few GPUs in the last few years and all of them have had coil whine.

That might not solve anything as if it is the PSU then as the new card is more powerful it may be the added draw that is causing the PSU's coil while to be apparent. I had this issue with an XFX 750w silver PSU, I didn't realise until I started running an over-clocked GTX780 that the PSU whined, it was always silent with my GTX670.

This is what I'm thinking...

Also I noticed just now while playing left 4 dead 2 at max quality that there was no noise... Only on newer games.

This is an equally valid point, and why I stated it may be GPU coil wine. I appreciate swapping the GPU out won't answer the question in that scenario.

Newer games equally doesn't answer the question as its possible that the increased demand falls on GPU and/or PSU.

OP - is there any way to determine which is making the noise? I know it might not be that simple...

I'm fitting some new fans so I might take the opportunity to test everything outside of the case today. So I will be able to determine the exact source of the noise.

I'm hoping it is just my old PSU.
 
A simple solution to narrow the suspects down is to run a benchmark like Heaven or 3Dmark, then take the side off the case, put a toilet/kitchen roll tube to your ear and find out exactly where the noise is coming from.
 
I moved from a silent GTX670 to a GTX780, and the system started screaming blue murder with the GTX780 installed.

It still did it with a different PSU, but it didn't do it in a different system. It sounded like it was coming from the motherboard :confused:

Anyway it was so annoying that I swapped it back for the 670, sadly. :(

As others have said, it may go away with time, but it is not a certainty. It is most likely to be either the GPU or the PSU.

If you discover that it is the GPU, return it
 
Well I rebuilt my system outside my case and found that the whine was coming from the psu.

The same sound can be heard coming from the 770 but no where near as loud.

What do you think I should do? send the card back or buy a new psu?

Try using another wall socket, preferably on a different floor (unless you live in a bungalow). Or try at a friends house? Coil whine coming from a PSU could mean it's stressed or it could be down to noisy/dirty power lines in your house.

The psu is plugged into a power conditioner in my studio so it's probably not noisy power lines.

I have also tried using the different connectors. The psu never did this with my old 5770.
