May I use two Power Supplies?

Hello, I have a question about using two power supplies! 🙂

I want to upgrade the video card, but I need to use a second power supply  to power it alone.

I can't replace the current power supply and just use one because this model uses a uniquely-shaped PSU that isn't upgradable.

Here is my desktop model information: http://www8.hp.com/h20195/v2/getpdf.aspx/c04168353.pdf

 

My plan was to purchase an Add2PSU, but I'm not entirely sure if that's necessary or if this is possible.

Can't I just tape a second PSU on top of my desktop, and then connect the new video card to it from inside the desktop?  So when I want to turn on my desktop, I will just turn on the taped PSU first, then turn on the main PSU with the power button?

 

Thanks for your help, I've been reading a lot about secondary PSUs and I can't wait to learn more about them!

People have done this before its not as uncommon as you think. The main suggestion i will make though is be sure the GPU you select will fit inside the case. otherwise you will need a pice extension cable and it will just be a mess...

Also i forgot to mention you will need to use a jumper on the PSU for it to power up. it will not power up unless the atx pins are either attached to a motherboard or have a jumper in place
