Hey there!
I'm running into some issues with a new PC build. I'm pretty novice to PC builds and this is my first solo build. I can't seem to get the system to power on (i.e., no reaction when pressing the power button and no lights/indicators on or shining when plugged into power). I'm not sure if it's something very obvious that I've missed connecting or connected incorrectly, but I've been scanning my motherboard manual and I'm pretty sure all the front panel connectors are plugged in, so the power button should be working. I've also made sure the PSU is switched on, and I believe all cables that need to be plugged in, are.. but I'm really not sure.
For some background, the new components here are the NZXT H7 Flow (Case), NZXT Kraken Z73 (360mm) and RTX 3080. I transferred the MOBO, RAM, CPU & PSU and from my previous NZXT S340 Elite case. I did buy cable extensions from LinkUP on amazon (8 PIn / 24 PIN) but I've tried connecting both with and without these cables and neither seems to make a difference.
I've attached some photos of my board and connectors just in-case there's something obvious that I've just missed plugging in/plugged incorrectly.
System:
Case: NZXT H7 Flow
GPU: Gigabyte OC RTX 3080
CPU: Intel i7 8700K
AIO: Kraken Z73 360mm
PSU: EVGA SuperNOVA 850 G3, 80 Plus Gold 850W
Motherboard: Asus ROG Maximus XI hero Z390 (WiFi) - Intel 8th & 9th Gen
Storage: Samsung 860 Evo SATA, Samsung 970 Evo Plus NVME
Any help here would be greatly appreciated. I'm really hoping it's just a simple mistake I've made with this being my first build and not an issue with any of the components.
Plugged in: VGA, VGA 2, CPU1, MB, SATA1
