PSU Not Sufficient?

[Nerv3]

I used to have an old HP Desktop found here: h10025.www1.hp.com/ewfrf/wc/document?lc=en&dlc=en&cc=us&docname=c01469329#N1171

Instead of just throwing the old PC away, I decided to use it for parts on my new build. I kept the CD Drive, Hard Drive, and PSU. I bought a new Motherboard (http://www.newegg.com/Product/Product.aspx?Item=N82E16813157293), RAM (http://www.newegg.com/Product/Product.aspx?Item=N82E16820231428), and CPU (http://www.newegg.com/Product/Product.aspx?Item=N82E16819115072).

Whenever I try to install Windows 7, the PC would just restart and continue to restart without continuing the installation. My guess right now is that the power supply is not enough to be able to power the PC. What are your guys thoughts? Is 460W too little?

it should be fine, does the whole system shut down, or does windows give an error message?

The entire PC would restart. At first I thought it was just part of the Windows installation, but then it would just keep restarting again and again and again, with each restart the length of time the PC remains on gets shorter and shorter. The PSU is almost 5 years old and it uses a 4 pin connector instead of an 8 pin one if that makes a difference.

make sure that all of the power and fan connectors are plugged in and that the power connectors match the connectors on the motherboard.

Alright, I got it to finally install. All it took was for me to unplug the Graphics Card. Is it safe to assume its the PSU?

sorry, weekend obligation.

no, it probably isn't the psu, you need updated drivers for the graphics card. Install windows, install the updated drivers from the manufacturer's website, and try again.
