Make sure you are getting those power specs right. I have rarely seen a base machine that runs off of 200W. Or did you get that spec from a motherboard or something. Older computers even, with nothing but the board and the output devices, without any carding need 400W or more.
What? There were no PCs in existence ever that needed more than 200-250 W for the basic configuration. And we're talking old dual CPU boards here, the hottest ones (which were mostly LGA 1366 and some LGA 2011 boards - those often idle at ~ 180-220 W with two 6+ core CPUs installed). And that's not even really "PC" systems but more like server grade stuff. Modern PC platforms consume 30-50 W idling (LGA1150+). Old inefficient single-socket boards (LGA 1366 X58 chipset systems are probably the worst here) were 100-150W at worst. I guess you're confusing the actual power consumption of the system with the number written on your PSU.
Those are (obviously) different things.A base system, with two added GPU, I would want to see at least 1000W, if not 1200 or more. I could be wrong
Have you done any GPU mining yourself? You're so wrong it's not even funny.
