my system is DG41RQ and dual core E5200 and 3 gb ram 250 gt sata 350 watt power supply my system work absolutely good when i purchased nvidia 9600 gt and install into system system performance very slow why?
CraigN is right. If I were you, I would look into buying a 500W Power Supply because it will not only allow your system to run at the normal speed, but will allow for future upgrades if you want any.
yeah its not a big deal to purchase a new power supply but my current power supply is just useless that's the matter because its a new power supply just purchased 3 months ago 🙁 but i think i should purchase a new one....
Well, the power supply was picked based on the specs of the computer you purchased it with. When you want to add more power, like a dedicated video card, that ups the power requirements by quite a bit.
