1.	Solve : Getting a new power supply?
Answer» I purchased a new computer two DAYS ago and today I bought a NVIDIA GeForce 6800GT OC PCI-E graphics card which requires at least 350W power. I never took out a power supply out before and don't know much about it. After taking mine out I saw that it was a 320W, so I went to a store and got pretty much a random 400W one. I put it inside the computer and started connecting ports, but there was nothing to connect to the hard drive. What do I need to know about my computer to buy the right power supply? And will too much more than enough power damage it? Quote 1. What do I need to know about my computer to buy the right power supply? 2. And will too much more than enough power damage it? 1. I. You need to know what kind of form factor your mainboard is. Most likely ATX. Most PSU are ATX. II. You need to know what kind of drive connectors you have. SATA or ATA. Most newer power supplies feature both. If not, you can often obtain ATA to SATA power conversion cables. SATA is a black thin connector, ATA is a thick white connection with 5 PINS inside the plastic casing. III. You need to know the amount of Wattages your computer requires. Power Supply Wattage calculator is an excellent web site to do so. 2. A more POWERFUL PSU will not damage system components as it will not attempt to deliver more power unless DEMANDED by your system. A PSU of 300 Watts or more is recommended for modern systems.Thanks, that explains why I couldn't plug it into the port. Another question, on the power supply box there are powers for AC Input and DC Output. Do I need them to be at certain powers to connect them to the computer or are they there just to SHOW what power are the outputs?Are you referring to the switch that shows either 230 Volts or 115 Volts?
