Considering cpu upgrade from i5-4460T to i7-4790K

Product ID:  N0X22AV#ABA, S/N 2MD548062M

I am considering upgrading from Intel i5-4460T cpu with the LGA 1150 socket to Intel Core i7-4790K which looks like a power supply upgrade is required - 35 - 88wats.

How can I upgrade the power supply - if needed?

Is the hp installed motherboard compatible with both processors?

Is the 23-q-140t power supply upgradeable?

Is the i7-4790K processor a "plug and play" process if the new processor works with the current motherboard?

Your PC's motherboard only supports the Intel 'T' series processors.

Even if there was a 150W - 200W power supply available for your PC there is no CPU cooling solution you could install that would keep the processor cool enough to work.

@JoeRet,

Welcome to our HP community forum!

You have come to the right place.

Surprisingly -at least to yours truly, your HP Pavilion 23-q140t All-in-One (N0X22AV) as fitted with the Crusher-U motherboard (SSID: 2B43) is, in fact, compatible with the fabled i7-4790K, which is an 88-watt TDP processor, and aptly named "Devil's Canyon"!

I found several Pavilion 23-q1xx Users with the Crusher-U motherboard who fitted this Bad Boy in their AIOs, such as this one: HP 23-q114 Performance Results - UserBenchmark.

Yes, you'll definitely have to upgrade your 90-watt power supply, with at least a 150-watt unit, such as this purchase example: Amazon.com: PowerHOOD 150W AC/DC Adapter Compatible with HP Pavilion AIO 27-a127c 27-a170d 27-a109 2..., which has the 7.4mm x 5.0mm connector size.

[EDIT:] And @Paul_Tikkanen is correct: the fact that you can install an i7-4790K doesn't mean you should, as your AIO can't adequately deal with the heat produced by this hot-running processor.

Hope this was helpful.

Paul, thanks again for the reply. Which of the Core might you recommend to pep up this old All-In-One to keep around another few years?  I don't begin to understand which of the "T" processors would be an upgrade and performance improvement.
And Thanks for the info - I would never guessed the heat issue.

Thanks for any info you can provide.

[Paul_Tikkanen]

You're very welcome.

I would install the best one listed on the motherboard specs page-- the Intel Core i7-4785T

It would provide a slight improvement over the processor you have now and would not require a different power adapter or cooling solution.

I don't even know how you would cool an i74790K without doing some extensive modifications to your PC--like hooking up a small air conditioner to it. 😊

Here's a side-by-side comparison of the two processors:

Intel® Product Specification Comparison

The i7-4785T has larger cache of the i5-4460T and supports hyperthreading whereas the i5 does not.

Not to mention it is just faster as far as GHz are concerned.

Thanks again for the recommendation.  I appreciate the humor even more - sometimes people are just too seriouc.  I'm sure I'll be back again for more help.  Have a great day!  Stay cool!

[Paul_Tikkanen]

Anytime. 

Glad to have been of assistance. 

You have a great day too!

@Paul_Tikkanen,

Speaking about CPU cooling, just very recently, this community member whom I assisted, added a large air cooler on an HP Pavilion 23-b130z All-in-One Desktop:

Where there is a will there is a way, I suppose!

Yes, I supposed if you want to do an extensive modification like that, anything is possible.

I would never, ever consider making any modifications that would not have the PC looking 'bone stock,' yet work perfectly.

To each their own.
