[SOLVED] How much power does RTX 2070 need?

[honn13]

My system is HP Pavilion 690-0034 with Ryzen 7 2700, 16GB RAM, Radeon RX 580 4GB, upgraded Samsung 970 Pro SSD, 1 HDD, and 1 optical drive. The PSU is 400 watts, rated 80 Plus Platinum. I want to upgrade my GPU to GeForce RTX 2070 Mini ITX 8G from Gigabyte, but my PSU is kinda proprietary in shape, so might not be able to upgrade it. Is the current 400 Watts (80 Plus Platinum) enough to power the RTX 2070?

You would need decent 550w PSU ...IF IT'S NOT PROPRIETARY , but more than likely it is.

I think 400 watts is pushing the envelope, personally, but, then some folks are more comfortable with running PSUs at 85-90% capacity than I am...

By 'proprietary shape', it's not even a standard SFX form factor, or anything? (If SFX, I know I saw a review on a 600 or 650 watt the other day)
