Production SFFtime presents: P-ATX V4 - 11L console case with support for large GPUs

[MarcParis]

Good question, it depends on the PCIe slot position. If it's in the 1st position, you can fit around 150mm tall gpu and if it's in the second then you should be able to fit a 130mm one. I will write all of this in detail once I release the full spec and compatibility list

Then I understand it as a yes.. You can fit Nvidia SFF GPU with an ATX Motherboard inside a 11L case.
As usual, I would be curious about the cooling capabilities of this kind of setup.

I just understood what you were stating @riba2233 . If the PCIe riser is put in the first slot, 150mm...however on an ATX motherboard, the first PCIe slot is a nvme slot normally..

Thus let's see your full specs..

 

[MarcParis]

More & more interested for the P-ATX v4...

I was wondering if the NH-L9x65 or ID Cooling IS-65-XT would eventually fit.
Also what is the size of the riser also

Yes, most ATX boards have PCIe slot in the 2nd position but there are some exceptions, like some gigabyte am5 boards and many mATX boards have it in the 1st position as well.

Haha didn't even knew about the IS-65-XT, must be somewhat new. It might fit tightly, depending on how precise their measurement is. But I still think that copper X53 with 25mm fan will cool better, and especially better than L9x65 which is pretty much obsolete.

There are three riser sizes, depending on the motherboard (178, 170 and 150mm). You can also use 200mm long one with two bends in some configurations.

 

[MarcParis]

In terms of riser length, why 3 lengths? Not 2, one for 1st pcie slot (mini itx) and one for the 2nd slot (ATX)?

Yes I know the NH-L9x65 is pretty...how to say that gently,..pretty terrible...even when it was launched. Issue is that my IS-53-XT is already in use. I will start for my IS-47-XT.

With the P-ATX v4 I would like to retest Console Pizza design efficiency with my ATX motherboard, RTX 5090 FE (double passthrough) and also my RX 9070 XT (open).
The last one is the most important as my reference point was based on my experiment with the RTX 5080 Ventus that was very noisy (poor thermals too) inside the U-ITX or the N-ATX or the FormD T1. However the RX 9070 XT prime I'm using, is performing very well in the FormD T1, thus I want to test it also.

I am also using Prime 9070XT in my P-ATX V4 prototype

Why 3 lengths? Because when you use an ITX board with a 3.8 slot GPU riser has to go behind the motherboard so it need that extra length unlike with an ATX or an mATX board.

Great GPU this Asus Prime 9070 XT. Even, as I've switched to Linux, it has nothing to be ashamed versus the RTX 5090 FE...as long as the FSR 4.1 is possible.

Ok clear for the riser length

Some news, I am preparing for the release, here is the shop page so you can trigger the back in stock notification: https://www.sfftime.com/product-page/p-atx-black

You can also see specs and compatibility list here, main product page will be updated tomorrow.

And here is the manual

 

[Tomate]

I have seen product pop on sfftime.com but you ask for mother model but I have not bought it yet and will clearly not buy it before ordering p-atx v4 so what to do?
I undestrand it is there for the pcie riser cable length, but I don't know what to say.
An other question, is there a white version planned?

If you are not sure just write that you don't know yet and I will send you a longer riser that can be folded and will work for all but one configuration (itx + 3.8slot gpu), no worries

White version is planned but not right away, probably around fall.

 

[Tomate]

It will be an ITX motherboard for sure (GPU is triple slot).
One more thing when scouping the manual I don't know if the black square here is intended:

Awesome, then just write the ITX motherboard, they all have the same layout so it doesn't matter like for matx and atx boards

That black square is the side view of the black M3 nut, it turned out like that I know, I will try to fix it in the future

P-ATX V4 Black (pre-production batch) | SFF time

* This case are from a pre-production batch, they might have some small imperfections such as slightly rougher edges and looser tolerances * SFF time P-ATX V4 is a 11 L case that supports a full sized ATX motherboard, SFX power supply, and a full-length 2.5 GPU. This makes it the smallest ATX...

Ok it's finally up

 

[Tomate]

Order one before seeing it was a pre-prod batch.
I hope it will not have too much imperfections.

 

[FLiP]

Will the GPU riser bracket also be steel? It's the one I stripped on the previous version

No worries, it's extremely small things, paint is great

Yes, everything has threads in steel now

 

[MarcParis]

Here is my initial test of the P-ATX v4

More to come !

 

[vkno]

Hi, are you planning on selling more of these?

 

[riba2233]

I am, I will have a few more pieces from this batch and I'm ordering the next batch now.

Awesome, thanks! Looking forward to the restock
