Hi! I got the Fujitsu Esprimo P520 Desktop. Spec: i5-4670 3.4ghz Turbo 3,8ghz , 2x4GB ram ddr3 1333mhz, mother board is Fujitsu D3220-A1 with B85 chipset, 500gb storage segate barracuda 7,2k RPM, the PSU is Fujitsu 260W (i don't know aobut the name of this psu or serial number). The question is, can i buy the nvidia gt 1030 without any upgrade, and If the power supply is not enough what could be the symptoms? (I apologize for spelling errors , my englando is very bad and google translator is not helping )
