HP Omen Obelisk/Edoras motherboard PSU compatibility?

[Mo948]

Hello everyone!

I have an HP Omen Obelisk 875-0014. I upgraded the M.2 SSD to a 1TB one, and the GTX 1060 GPU to an RTX 3060 (ZOTAC gaming). I also purchased a power supply to swap that out, this is where I ran into an issue.

TLDR: Does the Edoras motherboard have any restrictions as far as PSU compatibility?

When I tried to install a new 850W PSU (LC6850M V2.31), the computer would not start up; it does start up with the stock 500W PSU. I've tried a number of things (paper clip test on the psu and fan turns on, checking all cables and connections, etc) and I've come to two conclusions: either the new PSU is dead/faulty or there is some sort of compatibility issue?

Any help or commentary is appreciated!

hi

Since it works with the original power supply, obviously the problem comes from the new
if everything seems compatible, correctly connected, it is most certainly the power supply unit the problem
we could search here, but it seems to me that other users have replaced the power supply without any problem

"it does start up with the stock 500W PSU.  "

just out of curiosity, reboot with or without the new graphics card?

Hi! Thanks for posting.

I agree, that makes most sense. I had also seen others discussing upgrading their PSUs and being fine. I wanted to cover all my bases and make sure there isn't a weird compatibility issue (read somewhere that some Dell MBs are configured for only certain PSUs or something).

So yeah, I'll be sending the PSU back!

To answer your other question, it boots with the new graphics card just fine! Runs well too, I think the 500W is just barely covering the wattage I need.

Can you indicate the exact model of the card, with link
it would be nice, it can help someone who also wants to replace his graphics card
thank you

Absolutely! In case it helps anyone else:

I upgraded my HP Omen Obelisk (https://support.hp.com/us-en/product/omen-by-hp-obelisk-desktop-pc-875-0000a/23302709/document/c0612...)

by replacing the M.2 SSD and GPU with:

- 980 PCIe®3.0 NVMe®SSD 1TB (https://www.samsung.com/us/computing/memory-storage/solid-state-drives/980-pcie-3-0-nvme-gaming-ssd-...)

-ZOTAC GAMING GeForce RTX 3060 Twin Edge OC (https://www.zotac.com/mk/product/graphics_card/zotac-gaming-geforce-rtx-3060-twin-edge-oc-0)

I am currently using this setup with the stock 500W PSU that came with the pre-built desktop.

Hope that helps!
