Guide for Selecting a Power Supply

[BLIVEWIRE]

Hey,

I was looking to upgrade my power supply in my HPE Pavilion h8-1214. I was looking around on newegg and i found a Corsair TX750 v2. (Link to the PSU). I'm not the best with computers and I was wondering if this would fit into my CPU and if all the cables would connect correctly? I'm looking to upgrade my power supply to run a higher end graphics card for gaming. 

Thanks!

I can only offer a "yes it should work", as I upgraded my HP mid-tower with a Corsair GS700.

You might want to make sure about the dimensions of the replacement PS, or make sure you can return the PS if it does not fit in the HP chassis.

Electrically it should work too.

Hi BLIVEWIRE,

The standard dimensions for a HP power supply are 5.9 by 3.4 by 5.5. A larger power supply will reduce the distance between the power supply and the back side of the optical drives.  You might want to consider the Corsair CX600 as it has the same dimensions as the HP power supply.  The Corsair HX650 would be another very good choice.  It's slightly bigger but it's a modular power supply so dealing with the cables is simplified as you only use what are required.

Thank you for your response! That's exactly the response I was looking for! I just have one more question. Do you have any recommendations on video cards that would work with this power supply?

Hi BLIVEWIRE,

Please start a separate post for the video card and state what are your critical applications that are in need of improved video performance.

I plan on upgrading my Hp Pavilion p6620f with a new graphics card and psu, I was wondering if my computer is capable of supporting and using the psu in order to run the graphics card without having to buy anything other than the card and psu?

Hi J1mbo,

Review this posted document for background information.

The power supply that you are considering is about .8" longer than the typical HP power supply unit (PSU).  That means the distance between the power supply and the optical drives gets tight. Open up your PC and do some measuring as you need to do so anyway for the XFX video card.  The longer PSU will probably go past a latch inside the PC. You will have to decide if you want to live with that situation or buy another PSU that will correctly fit.  The Corsair CX600 might be a better choice.

TIP: Remove the front bezel (cover) and unlatch the optical drive and move it forward before you remove and replace the PSU. It will make the installation easier. The cables of the new PSU will be longer so find an empty bay and tuck them away to improve air flow.

Hello,

I'm going to be upgrading my GPU on my HP Desktop and it requires me to upgrade my PSU aswell.

It says I need a two 6-pin PCI Express supplementary power connector. Minimum 500W or greater system power supply with a minimum 12V current rating of 38A to run this GPU.

I have no idea of what PSU to get some help would be great (:

Thank You (:

Hi ogDnice,

Review this posted document for background information.  Space inside the HP mid-tower cabinet might be very tight fit.  You need to measure.

This EVGA GTX 660 TI card might be a better choice as it is a 9.5" card verses the MSI 10.4" card. same price.

The EVGA GTX 660 TI card only requires a 450 Watt PSU with 24 AMP on the 12V bus.  You still need two PCI-E 6 pin power connectors.  The PSU in your PC is 460 watts so it might be enough if the PSU has the correct connectors available. The card comes with a Y PCI-E 6 pin to dual 4 pin molex connectors that would would for the second PCI-E 6 pin power connector. The HP 460 watt PSU that I had in one of my HP PCs does not have the correct power connectors for the GTX 460.

The Corsair CX500 or CX600 PSUs do fit the physical dimensions of the HP PSU.

I will probably get the CX600 then and if I were to get a bigger case would that help out with the space?

Thank you 🙂
