Your system shouldn't pull too much current. Probably under 200W when folding would be my guess. I would fold on the GPU only as the CPU client has much worse Watt/PPD ratio. One option is to fold only when you'd have the computer on anyway as then the marginal increase in power consumption is really minimal.
You can save a bit watts by undervolting your CPU as your gpu won't be CPU bound.
good luck!
