Hey all!
I would like to know if PSU Seasonic FOCUS GX-650 (https://www.amazon.com/gp/product/B077J9QTDR/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1) will be sufficient for an EVGA GeForce RTX 3070 Ti FTW3 (https://www.evga.com/products/product.aspx?pn=08G-P5-3797-KL) given the EVGA website says the PSU should be at least 750W. I created a build in website PCPartPicker (https://pcpartpicker.com/user/luisperera89/saved/B7ZRVn) and according to that it says the estimated wattage is 538W (the missing 23W are because I had to create custom part for the water pump). I would like to confirm it's OK to use this Seasonic PSU.

AIB partners tend to reverse engineer reference designs which might need more power from the PSU. You can get away with a 650W unit(if it's brand new, not used) but I'd keep a headroom of 700W~750W in order to retain the PSU for a longer amount of time and also allow for other component upgrades down the road. As with any build that's watercooled, assembling is the fun part, disassembling it isn't, so I'd ask you to settle with a 750W unit from Seasonic or Corsair.

Thanks for the reply @Lutfij, the PSU has exactly 1 year old, I think it'll be ok, but I'm afraid of killing a component :confused2:
I'll go with a higher wattage PSU to be on the safe side, and because of what you said, to provides a better upgrade path.
I'll still have to go back to the wrench and bend new hard tubing because the previous card I had wasn't as big as this one, so I'll spend a few hours rebuilding the tubing again 😑, not fun
