Purchasing an HP desktop with SLI (Presumably Omen)

[Omj532864]

My goal: I was tasked, weeks ago, with speccing out and getting dollar amounts for a few options on a new desktop. My goals are to quickly process large point clouds and large amounts of 3d data, and run an HTC Vive (and possibly other headsets) for real-time review of our larger projects. I have set up cheaper options with single video cards. I need an option to show this manager for more capable performance.

So far: I have been told by multiple chat reps that they would get back to me in 24-48 hours with a machine that matches my request -- either a machine that comes with SLI'd RTX 2080 Ti's or a machine that I can put an aftermarket ATX power supply and two nVidia GPUs in. However, I've gotten no such machines back, and this has dragged on for weeks now.

What I'd like you guys to help with: Help me find a link to a customizable macine that can be set up with SLI, or provide me a link to a cart with one preconfigured that I can make adjustments to. Anything that gets me off of dead-center on the issue and gives me something to report is a huge help.

This is my last-ditch effort. As of now we order 100% HP workstations and laptops. I'd rather not mix, but my next stop is to start looking at other manufacturers, and see if I can find someone who wants to sell me a more powerful consumer-style desktop. The reps I've talked to don't even know what SLI is, and yet start asking me about what I want to use the computer for when I ask for help configuring an SLI machine. You guys can probably understand how useful and pleasant that is.

Hello @Omj532864 

The options for models will vary depending on what country you are in.

In the USA where Im at, I looked up the HP USA Store and found that they no longer offer SLI configurations (at least at the moment, but always subject to change). You would have to buy one, then customize it yourself with the graphics cards and PSU.

In the USA store...

The Omen 880-160se CTO (traditional case design, Configure to Order) uses the Tampa 2 motherboard which will accept 2 graphics cards in sli.

Comes with two PCI Express x16 physical slots (Gen 3.0), each slot with x8 bus lanes.

Can be configured with Intel i7-8700k or i9-9700k cpu's.

Or

OMEN X by HP Desktop PC - 900-260xe CTO (box case design, Configure to Order) uses the Hamburg motherboard and will accept 2 cards sli. Two PCI Express x16 physical slots (Gen 3.0). I dont know what bus lanes, most likely x8.

Can be configured with Intel i7-7740x through i9-7920x.

Hope that helps. I am not an HP employee.

That answers the SLI question nicely -- thank you -so- much. I greatly appreciate the help.

Do you know if either has a standard ATX power supply, or what my options are for power? The 2080 Ti's take 260w each, the i7-9700K at factory clock takes 95 watt. That's 615 watt before anything else, and the biggest power supply you can order in the 880 is a 750w. That's cutting it pretty close.

I'm not finding anything on the store that helps me see a list of applicable power supplies or clarifies if the 880-160se can run an ATX.

The options from HP only come with 500w or 750w as you found out.

For sli, you would have to upgrade the power supply youself after purchase. 

It will use a full size ATX format. You would want to measure the length inside and compare it to what ever PSU you're going to purchase to ensure a good fit, but it should be able to handle almost any PSU length wise. I see there is about 8 3/4 inches (22.225cm) from the back of the case, to the HDD cage in front. You'll want to leave room for the cables.
