Hello everyone, So I recently bought a used Dell OptiPlex 7010 MT (Mini Tower) as my main desktop computer, and I just noticed that the Integrated Graphics Processor of it is a bit old, and I want to upgrade it as fast as possible without making any changes to the internal default PSU (Power supplying Unit) or (Power Supply) Or If I can change the power supply,  Can you tell me which power supply specifically will it support?, and have you ever tried to use it on a desktop with the same model (Dell OptiPlex 7010 MT)? Please note that I have the following Specifications :  Processor (CPU) : Intel Core i5 3470 3rd gen of Intel Core i5 Processors (Ivy Bridge) Memory (RAM) : 8 GB of DDR3 Modules running at 1600 MHz, Dual channel mode. Graphics Card (GPU) : Integrated Intel HD Graphics 2500, 2 GB of VRAM, 6 of EUs (Execution Units) Power Supply (PSU) : I didn't do any changes to the default dell Power Supply which came with that OptiPlex, and I would like to change it if possible. Monitor (Display) : HP EliteDisplay E201 LED Backlit Monitor (1600x900 at 60 Hz, IPS) - Not advertising that product. Please tell me, Which GPU will it support as a maximum without a PSU upgrade, and if possible, which is the best PSU can this PC support if I can even change the PSU.
