S4MAX: Brickless S4M w/ 3090 FE and R9 5950x - 800W, 5l, water cooled

Well i finally got off my lazy butt and I'm restarting the 800w PSU project after my first attempt (old PSU made some weird noise)

I have designed and ordered a custom PSU housing. Once fitment is confirmed I'll adjust it properly.
Other than airflow, (going to start with a 40mm noctua) what do you think will help it lower temps? I'm thinking of Aluminum heatsink instead of the top cover somehow or more fans on the top cover if i can fit them.

Also what's currently the best Pico PSU for the 24pin? I'm hooking up the CPU connector to the 800w PSU

Great work, how did you get pin 8 (24 Pin: PwrOk/ Power Ok) from the PSU to the 24pin for the Mainboard?

what do you mean he just solder a wire onto the ps-on pin on the PSU and then solder the other end of the wire to the pico 24pin ps-on pin, you don't need to cut it like the 5vsb, thats all, but that's for the 600w of the PSU, the 800w is a bit different

If you just want to do 24-pin & CPU(EPS) then I'd look at the J-Hack 2426 or 200X (though honestly there are plenty of options for DC-ATX that are probably fine on AliExpress and the like).

Did a heatsink mod on the PSU, just have to make sure that it doesn't touch the chassis. As for the fan, i wonder if a chipset fan is fast enough.

Are the heatsink mounts not grounded?

I learned the hard way, i tripped a breaker. I measured it at 60 volts on the heatsink. Maybe from the bridge rectifier?

@petricor

The PCH fan works as the PSU fan

Edit: look at this sexy little fan

And yes, all possible air escapes are blocked off

 

[petricor]

I have a little fan update to share at some point... long story short: Summer+Gaming in VR+40mm Noctua fans don't mix

 

[riba2233]

Another dead psu?

Nooooo, now what do I do when I tell people "pff, you can go smaller"!?

What was the room ambient temperature when you killed it (the PSU I assume)?

 

[petricor]

No one died - that includes PSUs

Another dead psu?

 

[petricor]

No worries - problem already solved
Just need to get to posting an update! And as a little teaser: All key components including the PSU stay the same (no reason to undo any mods…)- and it involves cramming more stuff into the very same enclosure, so it shouldn’t disappoint!

Huzzah verrily!

well i have hit an air cooling roadblock. might go custom watercooling. The hard part is that there is only chinese waterblocks for the Zotac 3070 twin edge.
Here is the Alphacool ST25 92mm Dual Radiator (184mm) 227 total length

edit. yeah no way i can place the gpu ontop of the mobo with my cababilities

i bet you can figure it out. what do you think the biggest impediment is?

I need the length of the FE card or else I'll be close to 5 liters in volume. That and i might as well just refine my air-cooled case to reach 4 liters

it's pretty lame that ek put out that 3070 fe block with the terminal at the end of the card. could have been roughly r9 nano sized with the terminal on top.

Barrow has one with terminals on top

 

[NinoPecorino]

Barrow has one with terminals on top

yeah i saw that. wonder if they would do an acetal version

 

[AURMEND]

Yeah i picked one up for $50 used. When EK made a water lock for the Zotac 3070 they listed the thickness at 20mm vs 26mm on the Barrow.
