Bit stumped with an issue: Any help appreciated :)

Ill try and keep this simple as its a bit of an odd one but would appreciate anyones input.....this has me stumped.

System Spec - I54690 / Radeon RX460 / Asus H81K / 120 SSD / 500w PSU

I have a new build from budget old gen parts (but new stuff) and its exhibiting a problem. Every game crashes,, no matter what i play and i play alot of old and new games. The screen goes blank and it kicks me to Windows after a min or so. It basically exhibits all the symptoms of an unstable overclock (yet my Asus RX460 is at stock) - I have windows updated/ bios / drivers updated all the usual stuff but issue happens 100% of the time.

I tested my GTX1080 in the new build and it worked fine - I therefore assumed I had a faulty RX460 which is fair enough - ill RMA it it so no problem. The issue is my RX460 works fine in my main rig - no crashes and no issues. The 1080 out my main rig works fine in the problem PC - This is confusing me.

I will say the only difference in the 2 cards is the RX460 is powered by the PCIe bus only. It doesnt need additional PCIe power cables. Its almost like the motherboard isnt delivering enough power to the RX460 through the slot - My 1080 seems to be getting enough juice from the PSU so doesnt exhibit issues. The RX460 works fine in the main rig - just keeps crashing on my new budget rig.



What do you reckon? - potential faulty motherboard? Any help or suggestions appreciated.

Your motherboard should be delivering enough power using the PCIe lane. Strange issue.

Can you try underclocking it? If it works with an underclock it could be a power issue, but that shouldn't be the case on a motherboard that is so recent. I remember some 480 GPUs having issues with older motherboards, but never for an RX 460 on a motherboard this new. TBH no power problems should be happening on such a new board.

Might be worth trying to get a refund for a card with a PCIe power or a GTX 1050 Ti, which will likely use less power.

TBH that is the most budget of budget motherboards but it still shouldn't be doing that. Have you checked the slot to make sure it is X16? I would look up the manual but very busy. Also, check that the pins are all good in the PCIE slot. If that doesn't work I would make sure everything is seated correctly from the CPU to the memory etc. However, just odd that the 1080 works as it should..
