GPU Black Screen

How old is this.

The GTX 1080 is a high end card and so needs the stability of a Gold efficiency rated PSU, Bronze are only any good for integrated graphics or at most an entry level 64-bit type card, not saying that it is definitely the cause but the extra wattage required by the new system could just be a little too much for the PSU.

This is odd, when you have an add on GPU in the board when you power up the BIOS should detect the add on video card and by default disable the onboard graphics, this whether or not the add on video card is working.

Check in the BIOS to see what is set as the Primary video device.

Power supply is around 4 or 5 years old. It is set by default to detect an external gpu in the bios. Also someone else suggested it could be the psu but if it is I’d be surprised if it could power a 9600k without issues, what is your opinion on this?

The present PSU from new only had a three year warranty so may be showing it[ICODE]s age [COLOR=rgb(226, 80, 65)]** the fact that it can power the 9600k doesn[/ICODE]t come into the equation until the GTX 1080 is in the board, this because even the none Ti version of the GPU [COLOR=rgb(226, 80, 65)]** requires almost twice the wattage that the CPU does and that is when the processor is under a full load.

[COLOR=rgb(226, 80, 65)]** The none Ti version of the GTX 1080 only requires 1x 8-pin supplemental power dongle from the PSU, specs here you mention that your GPU requires 1x 6-pin + 1x 8-pin, this suggests to me that you have the Ti version which requires a minimum of a 600W Gold efficiency rated PSU, the Ti version also requires more than double the wattage that the new Intel CPU requires, 250W to be precise, you can confirm this for yourself here.[/COLOR][/COLOR]

It’s a 1080 but maybe an overclocked version. I am soon to start a new job so I will buy a much better psu and get back to you[/color][/color]

[phillpower2]

You could be right, a bit like some MBs have an additional ATX power supply for overclocking k CPUs

A better PSU is in order in any event, just be sure to go for a Gold efficiency rated PSU from a proven brand such as Corsair, EVGA or Seasonic, disregard anything from lesser quality well known brands, you can tell these by the warranty period, you want seven years minimum but if available within your budget go for ten years.

Okay thanks. It may be a week or so but I will update this post once I’ve received the power supply

[phillpower2]

No rush here, new job means that you may have other priorities to deal with first.

The two best that I could find;

Seasonic CORE-GM-650 Partial modular PC Power Supply

Corsair CP-9020133-UK TX550M 550 W 80+ Gold Power Supply Unit

Both are covered by a seven year warranty.

The prices seem reasonable, I will most likely buy the seasonic. Thanks for the recommendation

[phillpower2]

You are welcome and fwiw the Seasonic would be my first choice because of the extra wattage.

Received via PM from lfcben;

[COLOR=rgb(44, 130, 201)]Hi, to my surprise a new psu did get the card working again, I wonder what happened to it when it was out of use for a few days? Strange

Not really a surprise or strange lfcben, as was previously suggested the old bronze efficiency rated PSU couldn`t support such a high end GPU.[/COLOR]
