Upgrading Psu

Hp pavilion p7-1519c
Microsoft Windows 8.1 (64-bit)

Hi, so i decided i am going to upgrade the power suppl yin my system (here is the poduct page http://h20564.www2.hp.com/hpsc/doc/public/display?docId=c03635837) and the size of the current power supply is   (5.9 x 5.5 x 3.4 inches). I want to upgrade to a power supply that is (3.40" x 5.90" x 7.10"). MY question is will the new Psu fit?

Upgrading Psu

That is a pretty whack forum name. 😉

 

 

From the specs on yor PC:

 

Power Supply

Internal 300W (100V-240V)
  • Form factor: Internal ATX

  • Total wattage: 300W

  • Nominal input voltage range: 200-240V/3A (50-60Hz)

  • Dimensions: 150mm x 140mm x 86mm (5.9 x 5.5 x 3.4 inches)

 

That means for a psu to fit and be compatible with your PC's ATX case, it has to  be an "ATX 12v & EPS12V"  format PSU. Those of us who build our own PCs always make vcertain that the PSU is of the same format as the candidate PC case. Looking at the dimensions of the PSU is just not the way it is done. 

 

Take a look at the NewEgg.com website and you will see the PSUs are categorized by their footprint, or form factor.

You see, that's where I'm confused because the PSU I want to get is an ATX12v. But it is still bigger than my current PSU. So will this for sure fit because it is an ATX12v?

Upgrading Psu

If the existing original PSU is an ATX PSU as stated by HP, then an ATX12V that you purchase will fit.

 

The ATX specifications are described in the following document.

http://www.formfactors.org/developer/specs/atx12v%20psdg2.01.pdf

 

See pages 30-31 for dimensions. The dimensions are metric and are in milllimeters. You will have to convert the dimensioons that you have to metric to verify compliance with ATX specifications.

If that were my unit, and I wondered about the measrements, I would meausre from the back of the case, and see where 7.1 inches projects into the case, and allow for cabling.   BTW, what graphic card and what PSU?

The graphics card I'm upgrading into is an msi gtx 1060, the PSU is an EVGA supernova 650w G1. I will eventually be moving all of the components into a new case but for now I just want to know if his case will work with my PSU upgrade.

Just remember the backplate and the front power switch re-wiring will need close attention.

Hi,

 

If the PSU is not the same dimensions (5.5 by 3.4 by 5.9) as the original HP PSU then the PSU holding latch will not be effective. Please review this information.

 

FYI - I did install a bigger PSU (modular) in a HP case and while it did fit, the space between the PSU and the optical drive was tight. Also, I did have to tuck some of the extra cable length in a spare optical bay to improve air movement.
