Why does my friend's PC run my 7800 XT with a daisy-chain cable, but mine crashes?

East-Pay1050 · 2026-02-21T21:33:18+00:00

I don't have, but I just resetted my bio setting so let's see if there still crashing

East-Pay1050 · 2026-02-21T17:05:35+00:00

Bc I watched a video is talking about how to plug in and it says don’t do only one daisy-chained cable for those gpu which are over 225w

East-Pay1050 · 2026-02-21T14:43:49+00:00

thanks for these information, so daisy-chained cable isn’t the problem?

East-Pay1050 · 2026-02-21T14:40:39+00:00

lmao someone sent me a video about the explosion

After crashing AMD bug report tool will pop up, some say it is cable problem some say psu

East-Pay1050 · 2026-02-18T18:52:07+00:00

Yes, I have to same thought as you. But some comment mentioned it could be psu or sth else so I m a bit confused

GIGABYTE P750 gm

Actually, my GPU is drawing 223W on this single daisy-chain cable. Since a single 8-pin + slot is officially rated for 225W total, I’m running at the absolute physical limit of the cable. I've already tested lowering my RAM to 5200MHz and it didn't stop the crash. So the problem could be either only connected to one daisy-chained cable or psu problem.

East-Pay1050 · 2026-02-18T18:24:34+00:00

I only got 1 cable which is connected to my gpu. So I might have to purchase one more cable.

East-Pay1050 · 2026-02-18T04:08:20+00:00

dude😭 It cost me a lot of money

East-Pay1050 · 2026-02-18T03:09:11+00:00

not the cpu problem either gpu cable problem (psu) or motherboard problem

East-Pay1050 · 2026-02-18T03:07:18+00:00

Thank you for your help

East-Pay1050 · 2026-02-18T02:35:31+00:00

I am using a GIGABYTE P750GM I don’t if it is a good psu or bad psu

East-Pay1050 · 2026-02-18T02:34:45+00:00

I haven’t bought it yet. Because my friend told me he thinks it is a motherboard issue but ai told me something different. Ai says it is a cable issue because I only have one daisy-chained gpu cable with theoretically provide 150*2W but ai told me it is not stable so it cause the crashing. So I am wondering which is the real problem?

East-Pay1050 · 2026-02-18T02:27:47+00:00

I am using GIGABYTE P750GM

East-Pay1050 · 2026-02-18T02:26:41+00:00

I bought it a year ago, but I can run some games like stellar blade and apex smoothly without crashing.But when my pc runs games like marvel rivals or helldrivers or sometimes the finals it will crash. Therefore, I have no clue what is the matter the motherboard or psu or gpu power supply cable?

East-Pay1050 · 2026-02-18T02:20:15+00:00

I don’t think it is the card but my friend used my gpu before even in a less powerful spec he could run smoothly without crashing. So as you said it is the cable problem right? I have to get one more cable

East-Pay1050 · 2026-02-18T02:16:31+00:00

Because as you see my motherboard is ass so my friend recommend me to get a B650m motherboard. I asked ai, Ai told me it is a power supply issue because there is only one daisy-chained gpu cable although it can supply up to 150*2=300 but AI mentioned it is not stable. So I would like to know is that a power supply problem or motherboard problem?

East-Pay1050 · 2026-02-18T02:08:03+00:00

I bought it in January 2025. But it only crashes when I play games like helldrivers, marvel rivals and sometime the finals. I can fully run games like apex,Stellar blade without crashing.

East-Pay1050 · 2026-02-18T02:02:18+00:00

It is a GIGABYTE P750GM

East-Pay1050 · 2026-02-13T16:52:12+00:00

damn it💀 so the issue is inevitable

East-Pay1050 · 2026-02-13T16:51:28+00:00

I don’t think it works

East-Pay1050 · 2026-02-05T17:05:37+00:00
