Upgrading an OMEN by HP Obelisk Desktop 875-1xxx

[NonSequitur777]

Dear Community,

Occasionally eBay offers some extraordinarily good deals, like an HP Omen Z390 Motherboard Obelisk Desktop "Shire" motherboard (SSID: 8509) with p/n: L23867-602 (new!) offered for $59 -which I bid on and got it for $54:

This eBay screenshot which I just took shows why this is such an exceptional deal: this high-end HP gaming motherboard easily fetches $280+, and now you can purchase it for less than 5X below the going selling rate!  The Seller still got "hundreds of these in stock", FYI.

Anyway, then I started looking for a fitting gaming case for my newly acquired HP gaming motherboard.  Initially I looked at any number of heavily discounted gaming cases -you can purchase very decent cases with preinstalled ARGB fans for as low as $50, but I decided to bid for an HP Omen 30L Gaming PC case (p/n: M45086-001) to stay in genuine HP character, and purchased it (including a 750-watt power supply) for just $79:

The Shire motherboard is used by the OMEN by HP Obelisk Desktop 875-1xxx series, hence the "Upgrading an OMEN by HP Obelisk Desktop 875-1xxx".

Among other key components, I've got an i7-9700KF processor waiting, as well as a 1TB Acer Predator GM3500 M.2 NVMe 3.0x4 SSD.

This is essentially 'building a gaming PC', which is actually really straightforward and relatively easy to do. Will show this build step by step. 

Stay tuned: more to follow.

Kind Regards,

Wow, that's a MB great price. (Edit: great MB price).

I still have a Z390 MB and a 9900K setup running W11 like a champ.

Dear Community:

Looking for an HP Shire motherboard (p/n: L23867-002 / L23867-003 / L46079-001) I/O shield, to fit these ports:

Usually having no issues with finding such an unremarkable part online for sale, but this one eludes me.

Any purchase hints, clues or references are welcome.

And yes, I know: if I don't get an I/O shield, it doesn't really matter all that much. Without an I/O shield though, the gap in the case wouldn't look all that great esthetically.

Kind Regards,

Dear Forum,

Ah, forget it: I will 'build' my own DIY I/O shield:

Dear Community,

I had purchased a new "Omen Obelisk Liquid Cooling Fan Radiator Heat Sink" with p/n: L51046-001 a while back, but hadn't used it yet:

Will install it once the case shows up, assuming I can make this cooler fit in the OMEN 30L gaming PC case.

The description of this HP OMEN Obelisk AIO heatsink is:

"Liquid cooling thermal system for CPU, designed for HP Omen Obelisk 873-1023 desktops, 95W thermal management.

Enhance your HP Omen Obelisk's performance with the HP Liquid Cooling Thermal System. This state-of-the-art cooling solution is designed specifically for the HP Omen Obelisk 873-1023 desktop, ensuring optimal thermal management for intense gaming and high-performance processing tasks.

This design not only lowers CPU temperatures but also prolongs the lifespan of your components, maintaining peak performance even under demanding loads."

The universal rear I/O shield is cool. Never thought to check for something like this.

Knowing about this I/O shield will come in handy in the future.

It will be interesting to see if the HP Obelisk CLC CPU cooler works with the 30L case.

Esteemed Forum,

Shopped around and purchased an RTX 2080 Super via eBay for this build:

And purchased 2x16GB Corsair Vengeance LPX DDR4 3600MHz - CMK32GX4M2D3600C18:

Very nice.

I'm thinking about doing this with a 2013 HP PC for kicks.

I have an HP 810-150se not used in years. Going to see what I can do with this PC.

@Bill_To,

An HP ENVY Phoenix 810-150se CTO Desktop PC (E3W48AV) would make a very fine upgrade project indeed!

If I were to upgrade it, this is what I would do:

1.) Matching 4x8GB of DDR3 PC3-12800, 1600 MHz, Non-ECC, UDIMM, 240-pin RAM sticks, such as this quality/affordable 4x8GB dual-rank (2Rx8) Timetec RAM kit: Timetec 32GB KIT(4x8GB) DDR3L / DDR3 1600MHz (DDR3L-1600) PC3L-12800 / PC3-12800 Non-ECC Unbuffered ....  Mind you, theoretically it may be possible to use 2x16GB DDR3 RAM sticks, such as this purchase option: Crucial Technology RAM Memory 1 x 16GB DDR3 SDRAM 16 DDR3 1600 DDR3 CT204872BB160B at Amazon.com, but the problem is, apparently, that few DDR3 capable motherboards can handle 16GB RAM modules.  So, I would 'stick' with the aforementioned quality 4x8GB RAM kit option if I were you:

2.) Installing the very best x79 chipset compatible processor available, the i7-4960X (3.60 GHz up to 4.00 GHz, 6-Cores, 12-Threads, 130-watt TDP). Shop around, but if I were to upgrade your system, I would likely purchase this processor for $139 via this trusted eBay Seller: intel Xeon i7-3770K i7-3820 i7-3930K i7-3960X i7-3970X i7-4960X CPU Processor | eBay.

3.) Making sure that you get the most recent (8.20 Rev.A) BIOS version: https://support.hp.com/us-en/drivers/hp-envy-phoenix-810-desktop-pc-series/model/5399397:

However, I believe that there may be an even more recent BIOS version (8.21 Rev.A), which you can download from here: https://ftp.hp.com/pub/softpaq/sp74001-74500/sp74205.exe.

4.) Since your IPIWB-PB HP Pittsburgh2 motherboard is 24-pin ATX power enabled, you could upgrade your power supply in order to power a high(er)-end graphics card, like this User did: HP 810-150se Performance Results - UserBenchmark.

5.) Installing a fast SATA SSD as your primary (boot) drive, some of the best options for your legacy PC being: Samsung 860 Evo, Samsung 850 Evo, or Crucial MX200.

Thanks for the upgrade tips, will do.

The 4960x looks good. And the more RAM the better. 😀

I'm still using the HP factory RAM.

I have done a Corsair RM650x upgrade and a Samsung 2.5 inch SATA SSD. I got rid of the SSD cache drive.

And I installed (squeezed) a 1080 in there back in 2017 or 2018.

I've got to check the BIOS version.
