I bought a pre-built IBUYPOWER and have been adding to it ever since. I recently bought a 2070 super and had some concerns about power supply issues. The recommended wattage is 650w, and the power supply that is inside the PC has a max of 600w. The PSU is the model that shipped with the PC (HPG-600ST-F12S ATX 600W PSU 115-230V 50-60Hz). I've heard High Power models of PSUs, especially from IBUYPOWER prebuilts, are somewhat lacking so I was wondering if it is risky to continue to play with the 50w discrepancy?
