Hi everybody!
Just built a new computer in a small case (Fractal Ridge), specs:
AsRock MSI B550M ITX,
AMD 6600X w stock cooler,
2x 8GB Kingston FURY Beast DDR4-3600 DIMM CL17-21-21- Dual Kit,
2TB Lexar NM710 SSD, M.2 2280 PCIe 4,
Sapphire Radeon RX 6600 Pulse,
450W BeQuiet! SFX PSU.
I was concerned about using this small PSU, but the calculations were about 370W, so it should work fine. "Should" being the operating word.
I turn the comp on, the CPU fan starts spinning, so motherboard 12V pins work fine, as does the 20+4 connection, since the power button led and button itself work + 2 chassis fans work fine.
The GPU fans do not start spinning, being connected to the 6+2 PCIe power cable, and the cards HDMI doesn't send any signal to the screen. The card is connected via the PCIe 4.0 riser brackets to the motherboard, and I reseated it again to ensure it is connected ok.
I have put the GPU on an older comp with PCIe 3.0 slot and the fans start up, but there is no signal on the HDMI cable. I assume it's the low PSU on that comp, as even its iGPU HDMI port doesn't share any signal. This comp boots without a problem with its iGPU via HDMI without this GPU installed.
On the new build, I tried a combo of only one RAM stick, ressetling both, ressetling in different slots, I have also unscrewed a bit of the CPU fan, as there seemed to be some solutions out there due to the fan being too forcebly connected to the motherboard.
I have obviously tried other HDMI cables, made sure the TV works on a third comp.
I am prepared to do a BIOS flash install upgrade should this be an issue for either RAM or CPU, but without an iGPU, and the GPU not sharing a signal, I can't get to that step, should it be required.
I don't have a DisplayPort cable or a monitor to use it on, so I can't really check (quickly), whether the HDMI port on the GPU is faulty.
I can only think of
(1) dissassembling the whole thing and plugging the GPU directly into motherboards PCIe 4.0, so assuming one of the 2-part PCIe riser from Fractal is faulty;
(2) using a 500W ATX PSU, to see if the extra 50W helps boot the GPU;
(3) buying a bigger PSU, displayport compatible screen and cable to test other ports.
Will be doing them in these steps, but since I've been at this for more than a day now, please let me know if you see any silly mistakes on my part that could be a simpler answer.
I was planning on buying a new 4k TV in the next week or two anyway, but most of them don't have displayports :/
Thank you in advance!
Kind regards
