Important specs for my issue: Motherboard: N-Alvorix-RS880-uATX (Alvorix) video card: Integrated graphics using ATI Radeon 4200 Power Supply: Internal 250W (100-240V) Expansion Slots: 1 PCI Express x16 slot for graphics card Product number (to look up anything else): BV564AA I got my HP Pavilion p6716f pretty cheap and I'm starting to understand why now. I'm trying to upgrade the hardware, specifically the video card, and after googling the crap out of video cards I've realized I'll need to upgrade my power supply too. My question is how can I be sure what power supply will work in my pc and what wattage would be recommended? I've tried my best to figure this out on my own but I've hit a wall. I don't know if this makes any sense but because the motherboard and processor are AMD I was thinking of sticking with an AMD video card, probably in the 6000 series, problem is I dont know if it'll fit in the PCI Express x16 slot, take a look by looking up the product number on hp (id post the web page but this website won't let me) So there's my first problem. Second, if I can even get the video card installed I'll need a new power supply, and I have no idea what specifications matter for installing power supplies. While writing this I foudd this on newegg (VisionTek 900370 Radeon HD 6570 1GB DDR3 PCI Express 2.1 x16 HDCP Ready Video Card) Would this solve all my problems? If so, I have this feeling this specific video card will be pretty loud... Let me know please.
