The great thing about a Silver/Gold or higher name-brand PSU is that they typically deliver 100% power, 24/7. Buy a cheapo 1000w unit, and you are lucky if they provide half that, short term, without failure. (not to mention the 2-3% efficiency gain [at least] with the better units). So congrats on the foresight to purchase those!
I've been using high end Seasonics for years now, as I like to get a good decade out of a PSU - prior to seasonics, I was using Antecs and PC Power and Cooling supplies. The "sweet spot" of the efficiency curve on any PSU is in the 40 to 60% of capacity range, so for a host with a 125W CPU and minimal of everything else, I would prefer a 300w supply, but there are rarely any quality supplies in that range, so I've ended up with the lowest power premium unit for most of my hosts (~500watts, sometimes fanless because its the lowest voltage high end option). This may end up working to my advantage now that I'm looking at tossing some video cards that are more than just basic cards in these hosts. That said, the oldest of these supplies was purchased with the Q9650 in like... 2008, so its a 12 year old PSU that probably shouldn't run >75% max capacity for any significant amount of time.
Personally, I have found this 'e-sport' VERY addictive. Try to up the game to the 2060 Super or better, is my suggestion. For example, I have 9 EVGA GTX 1070's, because the price hit the sweet spot of $200-ish ( used, ebay) each some months back. They Fold under Linux at about (going on memory) 650,000 ppd. And they are fairly efficient with a TDP of 150watts (going on memory again). My ONE 2080Ti however gets 3,000,000 ppd at 250W TDP!!!! One card (2080Ti) could replace 4.5 1070's! (Warmer weather has arrived, so I can't run the 1070s for this challenge, without incurring a huge energy bill).
This review shows that the 2060 Super can pull > 250 watt on furmark, and a 2070 super can pull > 310 watts.

I'm not sure if folding uses the same amount of juice as furmark, but it gives me a good max draw to consider when sizing with my existing PSUs.
The reason I went with the 1660 super is that it has nearly the same performance as the 1660 Ti, which is second in Points per Watt (only the 2080 TI is higher) and second in points per dollar (only the 2060 is higher). My goal is to keep my folding power budget within the excess power I generate from my home solar panels - right now with 4 hosts folding / running rosetta, I'm producing about 34 KWh extra / day on a sunny day, but only about 6KWh extra / day averaged over the last week (cloudy days, what can I say). Since I'm constrained by power supplies and want to consider points per watt as well, I figured the 1660 Super would be a good first step. If I want more PPD I'll use the step up program to go to either the 2060 super or 2070 super for this card.
Long term, I've decided I'm going to update all of my systems to the sweet spot on CPU perf per watt scale, and revisit the high end video card option when the Nvidia 3xxxx series is released. Just replacing the Q9650 with a Ryzen 3700x would likely generate more points on rosetta than my 9650, A10-5800k, and A10-7870K combined, all at less power usage.
All that said, your contribution is greatly appreciated!
No problem! I don't get to game nearly as much as I used to, so this gives me a fantastic reason to play with computer hardware that I've been missing since I had kids.
PS: Not all projects perform so well with the 2080Ti....the quick return bonus system of F@H isn't implemented in other projects (although GPU Grid does award more for fast returns).
This is part of the reason I'm probably going to skip the really high end cards for most of my systems. I always keep 1 gaming system around though, and on that system I'll be looking at top end cards. Folding at home will just keep it busy while I'm not gaming
