Is this GPU dead???? GTX 680 No Signal on Monitor

[Richunix]

I have recently bought a GTX 680 EVGA model with a gelid icy vision aftermarket cooler fitted to it from ebay. The guy I bought it from said it had been removed from a system 12 months ago and was working. I now am not so sure as I tested it last night and it had no signal.

I tested it in my i3 6100 which has 8gb Adata XPG Z1 DDR4 2400mhz, 120 gb Sandisk SSD, MSI B150M Arctic Mortar, EVGA 450b power supply,

Hooked it up and no signal from the HDMI output but the fans on the cooler were spinning. Changed over to the motherboard HDMI and it booted fine into windows with signal. Tried the included dvi-d to vga adaptor on another vga only monitor and still no signal with the fans spinning.

Its not a problem with other hardware as far as I can tell as I had a GTX 660 ti and GTX 960 running on the same system with no issues through the HDMI. They ran benchmarks without issue.

When it boots no ezdebug lights stay on permanantly on the mortherboard. The VGA light does illuminate for about 4 seconds but then goes off. Not sure if that means there is an issue as I would expect it to stay on. The rest of the lights just cycle through fine.

Could the power supply only being 450w be an issue? I checked on EVGA Power Meter and it recommended that power supply was ok for that card.

I guess its a blown GPU or some other issue. Just wondered if thats the case if there is a way to confirm this?

If someone could help that would be great.

Cheers

The GTX 680 is a very hungry card indeed, at 195 W it could be a little too much for that psu.

I have an EVGA 650 BQ ready for another build. Would testing it with that prove the card is totally dead?

Like I said the EVGA website said the PSU can handle it and PC part picker seemed to show an overall watt rating around 350 for that system configuration.

Thanks

Hi there, Yes - a 650w psu would certainly be enough to power that card, if it doesn't work with it, then I would think it's pretty safe to say it's a dead card.

Same problem here.. my DVI and DP ports work, but no output on HDMI. Any monitor I connect to the HDMI port shows 'no signal'. I can't use my new projector, which is HDMI. My old projector had a DVI input, so that worked. But it's being replaced with the VW675-ES this week.

What's the trick to turning on the HDMI output of the GTX680?
