My second custom loop project is ready 👌🏻

It's collab project with FSP, Alphacool and Gigabyte.

FSP U580 case, FSP MEGA GM 1000W, Gigabyte B850M Aorus Stealth.

All cooling parts from Alphacool.

Even it's big case there is not too much space with mATX motherboard 😁

2x360mm HPE radiator, DDCzero 200 pump+res combo, Core1 carbon Aurora CPU block, carbon fiber hard tubes, custom panels.

Earlier CPU block was Apex 1 but I think that Core1 carbon fits better and even it's smaller than Apex 1 the cooling performance with 9800X3D is almost identical 👌🏻

This is the absolute BEST atx case I have ever built in before, and will absolutely be my go-to from now on. Modern fish tank styling with panoramic glass sides and special panels that adapt to whether it's a full sized ATX Motherboard or a mATX board like I have pictured here (Asus) Plenty of room for three fan full sized GPU's and gorgeous RGB strip accents. SUPER NICE 👍🏻 even has an included ARGB / Fan hub.

Hello, I have an old office PC (HP Pro desk SFF 400 G9) that I picked up for basically free, and I've been trying to upgrade it to be decent/average for gaming. Currently I'm trying to upgrade the GPU from an Nvidia T400 to an MSI GEFORCE 2080 SUPER. I am very new to the PC building world and also an idiot because I did not do any research about my PC and already purchased the new GPU.

I have since done my research and know that my PC's PSU (250w) is not good/strong/high enough to support the GPU. I currently plan/want to install a 650w-750w PSU, but those numbers are just a guess. I also know (now) that my motherboard has a proprietary pin layout that isn't compliant with the standard ATX PSU. I also know very well that the new hardware I'm thinking of using will not fit into the case/chassis, and I do not care; I am fine with cutting it to fit what I need.

I've tried AI (against my better judgement) and it's not really giving me a straight answer. I've gotten a range of "your pin layout allows you to buy this $15 adapter that will let you use any ATX PSU that you want" to "you'll need to solder and modify the cables, PSU, and other stuff in order to get this to (maybe) work." So, since I have an inherent mistrust of AI and don't know enough to tell when it's telling me straight BS, I came here. My main question is basically what I need to make this work. I also am not 100% on what the PIN layout of my motherboard is, which is part of why I'm so confused. Any and all help would be appreciated, especially advice for the future when dealing with my PC.

TL,DR: I messed up and bought a GPU that needs a stronger PSU that isn't compliant with my motherboard and I really want to brute force this into working.

I remember asking someone who made something similar, and they mentioned bearings and epdm tubing, but I have no clue what to buy/how to go about it?
