Buying a power supply and video card, where do i get the right size power supply?
Well here's the deal, I currently picked up an HP p6130f with the intentions of replacing the video card and power supply as everything else inside is pretty decent. I'm going to go with a Radeon HD 4850, as it seems to be a good card for the price. I believe the dimensions on the power supply are standard, so can anyone recommend a 700-800 watt power supply that will fit the 3.25 (height) 6 (deep) and 5 (length) dimensions?
The HD4850 is a 150-watt video card. It draws 75 watts through the motherboard PCIExpress 16x slot, and another 75 watts through the PCIe 6-pin connector which you connect to the PSU.
150 watts / 12 volts = 12.5 Amps on a PSU's +12V rail.
You don't need a 700-watt PSU to drive it.
The 450-watt Corsair 450VX has 33 amps on its +12V rail and will be more than plenty to power anything you can possibly stuff into that tiny microATX HP system.
That PSU the guy above linked to is laughably weak for a"680-watt" PSU. Its +12V rail has only 26 amps.
Get the Corsair 450.
