OMEN 880-010nc upgrade options

[Copyfalse]

Hello,

I bought this PC way back in 2018 and I would like to upgrade it a bit. The PC in question is https://support.hp.com/us-en/document/c05649151 with this motherboard: https://support.hp.com/za-en/document/c05530904

The motherboard has LGA1151 socket which should be able to fit several newer processors, yet in the possible upgrade tab there are listed only two processors. Does that mean the other processors would not work with this mobo, or is the list just not up to date with processors that launched later?
If it would indeed not work, is it possible to change the whole motherboard for some else? Or does the pc have any quirks that would prevent this? I'm asking because when I tried to change the cpu cooler, the new one did not fit onto the atypical cpu mount.
I'd love to upgrade this pc to i5-9600K (LGA1151) and rtx 4060 ti 16gb. This cpu has tdp 95W and the mobo specification says 65 is the limit. If that would be really a problem, I could instead take the non K version that has 65W TDP. But I can get either of those two for the same price, so the K version has better value. 
Any information is highly appreciated
Thank you for reading

@Copyfalse,

Welcome to our HP Community forum!

Your OMEN by HP 880-010nc Desktop PC (2BY24EA) can be upgraded up to an i7-7700K.  Your motherboard has the Intel H270 chipset, which is only compatible with 6th and 7th gen Intel Core processors, though HP further restricted compatibility to 7th gen processors only.

Since your Naples motherboard (SSID: 8308) is 24-pin ATX power enabled, you can also upgrade your power supply with any industry standard ATX power supply, as long as you measure its dimensions (LxWxH) for fit inside your case.

However, you don't need to upgrade your 500-watt power supply, because it is good enough to power up to a smaller-sized (dual fan) RTX 4060 Ti 16GB, such as this model: https://www.techpowerup.com/gpu-specs/asus-dual-rtx-4060-ti-oc-16-gb.b11301.

Hello, thank you for your reply. According to benchmarking sites the I7-7700K is only about 10% more powerful than my current i7-7700, so it doesn't seem worth upgrading. Do you think I could change the entire motherboard that would support newer CPUs? Or is there anything that would prevent me from doing this?

@Copyfalse,

Well, an i7-7700K may only be 10% more powerful than an i7-7700, it is still considered significant especially when paired with sufficient RAM and a decent graphics card.

Switching motherboards in a legacy PC like yours is likely challenging (trust me, I have tried with different systems) because of various reasons such as motherboard format, mounting, I/O wiring differences, etc. There may very well be higher-end Intel gen motherboards out there that would fit in your PC, but I am not aware of any.

Thank you for your input. I will try upgrading to the i7-7700k and 4060 ti.

 I've got one more question tho. The motherboard info page says that it supports max 65 tdp CPUs, but i7-7700k has TDP 90. Is it possible to upgrade it despite this conflict?

@Copyfalse,

You raised an excellent question.

The 880-0xxx desktop series were fitted with three different motherboards, one for AMD processors (Higos motherboard with SSID: 8309), and two for 7th gen Intel Core processors, the Tampa (SSID: 8307) and the Naples (SSID: 8308) motherboards:

The latter two Intel-based motherboards are very similar as you can see, with one obvious difference: the higher TDP ranked motherboard (Tampa) has heatsinks fitted on its VRAMs, presumably to deal with the extra heat an i7-7700K with its 91-watt produces compared with the i7-7700 65-watt TDP.  But wait: VRAMs temps are not much influenced by the processor running on its motherboard.

Also, I am not convinced (based on a wide range of upgrade projects I have been involved with) that the 91 minus 65-watt = additional 26-watt difference would make much of a difference to disqualify the i7-7700K for your Naples motherboard.

My point is, the difference in VRAM temperatures between the i7-7700 and i7-7700K would be very minimal in a well-cooled system. The primary factor in VRAM temperature are your GPU’s activity level, airflow, and cooling. However, in a system with limited airflow or a poor cooling solution, the extra 26-watt of heat from the i7-7700K might have a small effect on the overall temperature inside the case, including the VRAM.

So, in short, the CPU TDP difference itself would not be a direct cause of significant differences in VRAM temperatures, but system cooling might play a role in overall temperature management.

Meaning, this is why I believe you could upgrade to the 91-watt TDP i7-7700K processor, UNLESS HP programmed a strict 65-watt TDP limit, which I don't believe they did.

To illustrate what I mean, I was able to install a 127-watt TDP processor (an i9-9900KS) in an HP EliteDesk 800 G5 SFF, notwithstanding HP's specs claiming just a 65-watt limit: https://www.userbenchmark.com/UserRun/65413152.

Btw, I must apologize for my wordy response.

Anyway, if I was a betting man -which I am not, I would still go for the i7-7700K, accepting a small chance that it would not be compatible.  Because of this small probability, I did purchase various processors from Sellers who allowed for returns, but to date, I never had to return a processor that wasn't compatible.  Yet.

Alright, thank you for the additional info, I appreciate every piece of insight, no matter the length, that helps me to form an opinion on this matter. I will go for it then. Thanks for everything and have a nice day!
