I have a system without a graphics card and I am looking to buthe gtx 980ti or the gtx 1070. However, I am not sure if my FSP AU-650M AURUM 650W Power Supply can handle the load from these cards and I'm worried that if it can't handle the graphics cards it may damage them.

My system has an over clocked i5 4690k at 4.4ghz, 16gbs 1600mhz ram, a deepcool captain 240 CPU cooler and the FSP AU-650M AURUM 650W Power Supply

Will this power supply be enough for all this and a 980ti or 1070, and will it be able to supply them for a while until I can afford a better power supply?

According to PCpartpicker you are looking at a 461 watt power draw - that should be fine with a 650 watt power supply. Accounting for overclocking the CPU, you are still comfortably within 650 watts. PSUs run most efficiently at about 50% of their peak load. The reviews of this power supply aren't stellar, so you may want to upgrade at some point to a more reliable supply.

Also, the 980 Ti pulls about 80 more watts than the 1070, according to pcpartpicker. With the 1070, it estimates you draw about 380 watts (again, without accounting for overclocking). This puts you in a much more comfortable position with your current power supply.

Yes it is 80+ Bronze, not gold, but that doesn't mean it isn't quality, it just means it's efficiency is rated a few % less. The unit is 'Tier 2'

I wouldn't think you would need much more than an 850 watt unit unless you plan on dumping some heavy draw components in, like multiple GPUs. Running around 500 watts would put you in the comfort zone for an 850 watter, giving you more efficiency than you have when you are nearing the edge of the PSU wattage rating.

Overall, I would say if you go with the 1070 and its lesser power draw, assuming the parts you mentioned are the bulk of your power drawing components, you should be fine with your current PSU. With the 980 Ti, if you are running the card hot a lot and stressing your PSU, you may want to think about upgrading - especially depending on how much of an OC you have on your CPU.
