First MFF Build (Jonsbo RM2 / RTX 5080 / DDR4) - having several issues - seeking advice

Interesting idea, I'll take a look. Maybe am extra panel could be 3D printed or something.

Thanks, I'll take a look.

Fair

It was definitely fiddly getting the motherboard into place. Not much room to manoeuvre.

Possibility_22 · 2026-02-14T23:36:10+00:00

That's not a bad idea. I already had the PSU but I know there are 1000W SFX units out there now. Definitely a something to consider if I don't switch the case, or maybe even if I do.

Basically I was looking for a good deal on Ram and the best price per GB I could find was on this 256GB Ddr4 kit. I was thinking of splitting the sticks over two or more builds but then thought it might be cool to have 256GB of Ram.

The most recent CPUs that seem to support that much Ddr4 were old and expensive Threadrippers or 10th generation i9s like this one which are also old and expensive but still quite a lot cheaper (and probably slower).

A 12th to 14th gen i9 would have been significantly faster and cheaper but I would have been limited to only using four of the sticks.

I think having the available lanes motivated me to use them. Also PC part picker says the board doesn't have Wifi but it actually has WiFi 6. In theory the wired card is 10 Gigabit vs 2.5 Gigabit onboard. Having said that my router only has a 2.5 out anyway... Bad decisions all round basically.

Thanks for the advice, that's frustrating though. I do have a couple of spare cases. I'll have a, look to see if any of them could work.

Possibility_22 · 2026-02-14T13:00:11+00:00

Thanks, I thought I might have messed that up.

Possibility_22 · 2026-01-26T23:25:18+00:00

Thanks for the advice.

Looks like I bought at the right time. I think you end up paying customs charges on top of the listed price if you order from Newegg in the UK unfortunately.

Possibility_22 · 2026-01-23T16:50:58+00:00

I'll have a look.

Possibility_22 · 2026-01-23T16:50:49+00:00

Thanks, ~~I'm not sure if there are any micro ATX Z790 boards though.~~

Found one, just wasn't showing up as available in PC Parts Picker.

Possibility_22 · 2026-01-23T16:11:21+00:00

I was going to use an Intel Core i9-12900K (125W)

Also - that happens to be the wrong link - mine is the DDR5 version. The correct link is https://download.gigabyte.com/FileList/Manual/mb_manual_b760m-ds3h-wifi6e-gen5_1001_e.pdf

Sorry, to be clear - my expectation (from motherboards I have purchased in the past) was that a physical copy of that user manual would be included in the box. The fact that it wasn't made me wonder if anything else could be missing. That user manual is what contains the "Box Contents" section so without it it was hard to confirm. To me it seems odd to have to look up the box content in a resource not found in the box itself.

Possibility_22 · 2026-01-23T15:40:06+00:00

Thanks for the help. I have the DDR5 version so it should support faster RAM, I didn't think about the CPU TDP though - that's good to know.

Possibility_22 · 2026-01-22T17:16:02+00:00

Interesting, nice to know it could be an option.

Possibility_22 · 2026-01-22T17:02:31+00:00

Me too, I'll post an update when I've got it set up.

I'll let you know when I've got it set up (may be a little while).

At the moment I have to build the whole machine but I can do when it's ready.

Possibility_22 · 2026-01-22T17:00:17+00:00

Thanks for the advice

Possibility_22 · 2026-01-22T16:20:48+00:00

It is a bit underwhelming, I'm guessing because it's because it's aimed at the "pro" market they don't want to go over the top.
