Just upgraded my power unit from a corsair AX750 to a 760, I was having starting problems before. That is not really why I posted on this thread, it appears to me that photos and videos are brighter with more colour. What I was wondering was having installed the new power unit would this improve the graphics card or make it somehow work better?? not the motherboard one. The old powerunit was only 4/5 years old and very slightly having less power.
What do members think ? and thanks in advance for replies
 
I've had several failing PSU's over the years and although the symptoms are fairly random and difficult to track, thats not one I've encountered. You could simply test this by unhooking power to additional hard drives, dvd players, removing any usb devices, and any other non essential devices. There should be minimal power draw in this state which if you calculate a PSU losing 10% of power per year should still have sufficient power at a 750W starting point. Is it brighter in this state? Does it darken as you plug devices back? Be sure to have curtains drawn and be in a darkened room when doing the comparison so its not affected by a passing cloud for instance.
You could go so far as to take a picture at a set iso, aperture, shutter speed in each of its states to provide you with evidence.
It would be an interesting experiment if you have the time/inclination.

I do have a corsair unit myself which has been running 24/7 in a server for the last several years without issue. Actually, if I recall correctly, mine came with a 7 year guarantee so you should check if yours is still covered.
 
Already installed 760 PU this evening and maybe it is just me thinking the photos and videos are better. The way I look at it is if there is less power ,albeit from a less powerful PU,and the old unit is not working at its best maybe it does affect the graphics card. I was thinking along the lines of a torch, as the battery gets less power so the light it shows is dimmer. Maybe a wrong analogy just a thought
 
Your graphics card just tells the monitor what colour to display and at what brightness. These figures can't change with the amount of power the graphics card gets. The power to display them comes from the power lead in the monitor, not the graphics card.

So no, it can't affect it.
 
Actually, thinking about it, if the graphics card isn't getting enough power, it wouldn't have the intelligence built in to say 'hold on, let me turn the brightness down a bit', but rather would likely start producing glitches & artefacts as its GPU cuts out and can't finish its calculations for what to put on the screen.

What he said.
If the GPU was not getting enough power (normally under max load, I.e. gaming or video encoding) you'd likely see system instability.

Colour accuracy due to PSU would be very unlikely. In fact I'd go as far to say its probably not what's happening here.

Presumably the display is calibrated?
