Unsure about my psu for a gtx 1080ti

[dylza]

Sorry if this may be under the wrong forum category i was unsure.

My system specs are:

cpu: i5 6600K currently stock 3.5ghz
mobo: Gigabyte Z170x gaming 3
ram: 16gb DDR4 3200mhz
gpu: 1060 6gb (Upgrading to GTX1080ti Auros OC 11gb)
ssd: wd blue 250gb
hdd: seagate barracuda 2tb
current psu: Thermaltake TR2S 650w 80 white (cost around $80 AUD ~ $60 USD)

PSU Calcuators say the system should draw around 540w (max)

My question is that i have recently purchased a gtx 1080ti with the recent price drops from the rtx series cards however a few months ago my old psu blew for no reason.. as a fix for in the moment as i needed my pc i opted to get the TR2S it didn't seem to bad and has been running the pc now for 5+ months. With my recent purchase i was wondering if the Thermaltake TR2S 650w will be fine for the GTX 1080ti Auros OC or would it be better to hold onto the card and wait till i have enough money to purchase a better psu and then upgrade... if so any recommendation?
Thanks!!

If the price is great on the 1080ti you should get it... Total power consumption with the new card will be around 400W in full load.
Your PSU is not a great quality unit(you should avoid thermaltake and cooler master generally) but it should handle the card for now... it also has 2x6+2 pin power connectors which is what a 1080ti needs.

When you have the money you should definitely upgrade that PSU asap.

You can also go with the 750W vrersion of these PSUs.. it will give you more headroom for future upgrades.

The TR2 series has never been that good, especially the older ones (the bronze ones made by FPS are OK, though not great). I personally wouldn't want to run a GPU that expensive with a mediocre power supply.
