RED LIGHT STARTS BLINKING ON MY GPU WHILE PLAYING GRAPHICS INTENSE GAMES. ASUS ROG ASTRAL 5090

please suggest a solution  its been 3 months since i got this gpu

If youre only 3 months after buying , ASUS should honor diagnostics or replacement if needed but heres a simple check that has worked for some. Fully unplug and reseat the 12VHPWR cable
1. Unplug cables , inspect closely for melted pins or discoloration - just one pin can ruin your day
 Replug with firm pressure until it clicks—some users miss full seating by just a hair.

2. Use native ATX 3.0 PSU cable
• If youre  using an adapter (e.g., 3x 8-pin to 12VHPWR), switch to a direct cable from a modern PSU
• Adapters are notorious for uneven pin load

Since its no doubt under warranty keep it simple and if those dont get it contact Asus or whoever you bought from  and let them know. That red blink isn’t just a warning—it’s your GPU saying, ‘Check my lifeline (voltage supply)

The gpu is in a custom liquid block. Can i still claim warranty?

[Ima_Tech_Geek]

Ahhh water block it has..that changes things a bit. ASUS’s warranty terms say any disassembly or modification—including installing a custom water block—voids the standard warranty, even if done carefully. They might make an exception if you reinstall the original cooler cleanly, but you'd have to ask them directly. I'd try the simple checks first (cooling, cable connections at gpu, even reinstalling the drivers), and then all you can really do is contact them  and see what they say.” Truly hope it works out for you...they are  not a cheap card to buy.
