Need Help Finding PSU Upgrade for HP Envy 750-124

HP Envy 750-124
Microsoft Windows 10 (64-bit)

I just purchased a HP Envy 750-124 computer, and needed to upgrade the power supply unit so that I can use my GeForce GTX 760 video card in it. The card requires a 400w power supply, but the computer only has a 300w power supply and no extra cable to actually plug into a video card. Searching around, I see that it is a uATX, but I can't seem to locate any power supply units that have a 4 pin (square) plug for the motherboard, 24 Pin (rectangle) plug for the motherboard, SATA plug for the HD, small plug for the Ultra Slim Tray SuperMulti DVD Burner (has the same 'L' shape as the SATA connectors, only very small, labelled 'P5' on the connector), as well as the x6x2 connectors for video card.

 

Can I get a better power supply unit directly from HP (anywhere from 400-600w)? If so, where can I find them on the website? My searches have turned up very little so far. If HP doesn't seel these, is there somewhere I can find a compatible power supply, or have I just wasted $811.00 on something I can't upgrade?

The P5 connector is the molex 4 pin standard used for older model hard drives.

 

PATA hard drives and most other IDE devices use a standardized, 4-conductor power connector like the one shown at the right, which is called a Molex or P5 connector. This connector is becoming a lot less common as SATA displaces PATA as the drive interface standard for desktop computers.

If this agrees with what you need then here's a nice Corsair CX500 for you.

 

1 x 24-Pin main connector
1 x 8-Pin EPS12V CPU
2 x PCI-E
5 x SATA
4 x Peripheral---------------------------this is the old style 4 pin Molex.
1 x Floppy

Hi,

 

You will not find a PSU with the thin DVD power connector.  If you search the forum you should find the adapter cable as this question has already been answered before.  I believe NEWEGG carries this cable.

Need Help Finding PSU Upgrade for HP Envy 750-124

I tried searching, but maybe I didn't use the right words; all I came up with was someone had some kind of fluid leak on their PSU and another had an unrelated issue with their 750-124. Just to make sure I am talking about the same thing, I took a couple of pics on my camera. From the sound of it, Big_Dave answered the question, I think, but here are the pics to make sure I don't spend more money on something I may not need:

And here is a pic of the actual connection slot (sorry for the brightness, my cell phone light isn't adjustable). The opening where it connects is that same "L" shape as the SATA connections, but is of course MUCH smaller:

*Edit: Also, if someone could tell me the name fo this type of connector, or the name of the converter I need, I would greatly appreciate it. Thanks!*

Hi,

 

Your photos could be clearer but the cables going to the DVD drive are power and data.  The cables are reduced in size to to the thin construction of the DVD drive.

 

Most of the specialized connectors that are used by HP are "pigtail" adapters.  You might check the "pigtails" for a part number tag.

 

The bottom connector that you posted an image of is a SATA connector due to it's shape and the number of contacts.  The top connector is power and there should be a posted adapter cable on the forum.  I believe that it was "tagged" but then I could be wrong.

 

 Perhaps like this adapter cable.

Sorry about the picture quality; it's probably due to a combination of the brightness of the light, combined with the fact that my hands naturally shake (even if just a small bit). After many, many combinations of terms in the search function of the forums, I think I finally figured out what it is: A slimline SATA, which means I will need a slimline SATA to SATA connector. Looking at NewEgg, I thinkI will need something along the lines of this: slimline_sata_to_sata_power , just not that long. The smaller bit (the Slimeline SATA) looks to be about the exact size I needed for the DVD player/burner, and the 'male' SATA will fit into one of the spare SATA power connectors, although I guess I could go with one that has a slimline SATA to PATA adapter (shown in the picture of the first reply after the original post), as I have some of those connectors available.

 

Looking at the actual Slimline SATA connector, I think there was an error when the plastic shell for the connector was molded; it juts has some small rectangles in what looks like an attempt at braille. Still, I'm positive that it's a Slimline SATA connector now; not only does it have that "L" shape in the connector, but it's also the right size ratio to the SATA in that picture.

That adapter for the mini SATA was most helpful. I have the 750-124 too, and I wanted to update to a better PSU and Graphics Card as well. Thank you! I already have a PSU (630w/730w peak), so I just ordered the adapter and card. Did a Nvidia GTX 950. :OpenSmile:
