PSu and upgrading CPU

Omen 870-250no
Microsoft Windows 10 (64-bit)

Hello :OpenSmile:

 

I was thinking of uppgrading the cpu in this computer, because the i5-7400 isnt fast enough for the GTX 1070 which is in the system. ( dont know what HP was thinking here).

I think the desktop only comes with a 300w PSU, and the i5-7600 needs 95w.

Do you think it will work? i5-7400 and i5-7500 only needs 65w but putting in a 7600 or 7600k will that work witout changing the  psu?

 

Best regards Frank

Frank,

 

The processor upgrade information is listed here.

 

Do you suppose that there is a reason that HP didn't list the models that you have mentioned?

 

I am not sure what you are doing since most NVIDIA GTX 1070 manufacturers specify a minimum of a 500 watt PSU.

So it thats so, why does HP omen comes with a 300w psu and 1070?

Hi,

 

The last time that I looked at the specifications for your PC it didn't list a 1070 and now it does. Go figure as it wouldn't be the first time that HP has changed specifications without leaving a trace of an edit update.

 

The issue that I see for the 1070 is that people will see the 1070 and think that any 1070 will work. That will become  a problem as 1070 goes from 150 watts to 215+ watts (requiring two 8 pin auxiliary power connectors).

 

I can't say how HP is rating the power supply in your particular unit. It could be output wattage and not source side wattage draw or a documentation error.

 

The typical 300 watt PSU used by HP in the past didn't even have an auxiliary PCIe power connector.

 

Do us all a favor and post an image of the power supply label.

So do you think a I7-7700 or i7-7700k will work with the current psu?

Hi,

 

I would say that the calculations on the side of the PSU are not accurate for the PSU that is installed.   The two 12v bus amperages exceed the total PSU wattage rating of 300 watts.   "Houston, we have a problem!" :Surprise:

 

Seems like the PSU should be a 500 or 600 watt model based on the efficiency rating.  I calculate 439 watts maximum based on the stated amperages.  The 12v amperage is 336 watts and then add in the 3v and 5 v wattage of 103 watts.

 

The label appears to be wrong.

Okei.

So if thats so, is there anyway or anything i can do, to know excately how much power the cpu is?.

Is like i dont want to gambel with my money on a cpu and it might not work or get damaged. 

Maybe i should send a message to HP and ask if they can confirm what type of psu it is?.

I have asked HP to look into the issue.  Please be patient.
