[SOLVED] Need help with a Zotac RTX 3090 PC build

[13rws]

Hello guys, a complete noob here in PC building. I bought a Zotac RTX 3090, now my system isn't showing display. I called a technician for helping me with the build, he connected only one 8-pin socket in the GPU to the power supply, the CPU fan is working, the GPU is showing RGB but nothing on the monitor.
Please refer to this image:https://lensdump.com/i/ZEWgY5

So my question is:

• Are both the 8-pin sockets needed to turn on the GPU?
• Is it possible that RGB LEDs in the GPU will turn on if only one 8-pin socket is connected?

My system is :

• Ryzen 5 3600
• Samsung 980 Pro M.2 PCIe 4.0 NVMe SSD
• Aorus X570 Pro Wifi mobo
• Deep Cool 850W SMPS
• Zotac RTX 3090
• GSkill RipJaws 32 GB 3200 MHz DDR4 Memory (1x32 GB)
• Antec NX200 cabinet

Yes, both power connectors are required. If that "technician" didn't know that, then you should avoid ever letting them work on your system again.

What is the ACTUAL model of your Deep Cool PSU?

Thank you so much for your help.

The actual model is Deep Cool DQ 850-M-V2-L

Here's the datasheet: https://www.deepcool.com/product/powersupply/2020-04/10_13125.shtml

Not the worst power supply out there, based on what could be a very good CWT platform, but it uses some pretty inferior parts so early failures or premature degradation are definite possibilities with this unit.

I'd connect both 6+2 pin PCIe power connectors, with the system off of course, and then retry. Make sure you are using the 6+2 pin PCIe/PEG auxiliary connectors and not trying to use one of the 4+4 EPS connectors, which shouldn't fit anyhow, but I've seen people force all kinds of stuff where it doesn't belong. And from a "tech" who thought just one connector was sufficient, it wouldn't surprise me. Look at the link for "cables" on the product page you linked to for identification if necessary.

Agreed. If possible. Somebody like that though, I'd be pretty doubtful about them being stand up on this kind of rip off behavior. If they even charged him that is.

Somebody was definitely clueless in regard to how things actually work.
