Upgrading Video Card/power Supply: Tower Question
I'm currently trying to upgrade my computer with a graphics card for gaming. My main issue is whether or not a new power supply and graphics card will be able to fit inside of my tower.
My computer is a Lenovo 3000 H210 57094408 Desktop PC, and the "form factor" of the case is "minitower". Can a DiabloTek PHD650 650-Watt Power Supply fit inside of a minitower case? Its form factor is listed as "ATX" but I read online that some power supplies are able to fit in many different form factors, is there any way to check for certain?
Secondly, the graphics card i was looking at is a EVGA GeForce GTS 250 Video Card. I've been looking everywhere online but I've had trouble finding out if this card can fit inside of a minitower as well.
Sorry for the newby question, let me know if it was too vague. I'm clueless about hardware upgrades so I'm not sure what I'm doing!
Thanks in advance.
