Sorry, long read in EN...
The street price difference between a FOCUS Plus 550 and a 650 is around € 10 or € 15 A few beers... or an IMAX movie...
Per my view, I would take the 650 because you have a better chance to run in the hybrid mode more of the time so the fan is not rotating so it is without sound and your fan's lifetime is for sure not going to be an issue and you have some extra headroom of 100W.
I am not sure why some people are very fixated on using the lowest power unit possible. The price differential is not that big and it's not like you buy a 650W power supply then you pull 650W from the wall socket all the time. I personally would feel more comfortable to have some headroom just in case my VGA needs change or something else I want to do with the system... I have one computer that still has a Platinum 1200 from ages ago because I had quad graphics cards in that system and it changed to SLI and now it is a single card and still that same old power supply. No need to get a new power supply.
15 or 20 years ago, all our system builder customers like Vobis or Actebis or even the old Dutch Tulip, all made sure they bought a power supply that will run at 70% ~ 80% of maximum continuous output most of the time so there is no waste or engineering overhang. Sometimes worse... I remember one system maxed out at 300W total and the buyer wanted to buy just a 280W power supply figuring the peak power, which is around 20% ~ 25% over continuous should be able to handle the max usage. They did this is because buying 50.000 power supplies per month meant every 1 dollar saved was 50.000 dollars saved. 50.000 was a lot of dollars 25 years ago.
Also, the systems were not so often upgraded as today. People did not buy a base system and then go out and change out the VGA 1 year later, not as readily as today anyway. So, very often you would buy the system and it is pretty much set until your next system purchase.
But now it is a different story. Many of our system builder customers are putting in higher wattage power supplies because they know expandability is something many of their customers appreciate. There was a big push for low power cards and then it became more powerful and then SLI or Crossfire and then now single cards with power consumption from low to high and then maybe reduction again with 7nm GPU. Because the market is so dynamic and because the power supplies today are more and more stable in terms of the specification for cabling and because of modularity of cables so if the connector types change, all you need to do is change the cables, then it would only make sense to spend the extra €10 or €15 on 100W more and have some flexibility later on.
It seems some here on this forum really prefers the BitFenix 450 Whisper, It is a nice power supply but for the same price or a bit more, there are other options...
450W
pricewatch: BitFenix Whisper BWG450M >> € 82,50
550W
pricewatch: Seasonic Focus Plus 550 Gold >> € 80
550W
pricewatch: EVGA SuperNOVA 550 G3 >> € 84
550W
pricewatch: Corsair RM550x (2018) >> € 92
650W
pricewatch: Corsair TX650M V2 >> 75
650W
pricewatch: Seasonic Focus Plus 650 Gold >> € 95
I am not pushing anyone to spend any money they don't want to, but I would pay € 15 more to get...
- 100 to 200W more for some flexibility later on maybe
- Better chance to run in hybrid fanless mode more often (not sure if the BitFenix 450 has a hybrid mode...)
- 10 years warranty
- Probably easier to eBay a 650W than a 450W when you want something entirely different...
But then that is just my personal opinion.
