PSU Calculator query (PSU Max Wattage less than on Calc)

[Meddling-Monk]

So I'm looking at some PSU's that interest me and that are still available to obtain (just about), but the thing I've noticed is that when I put the numbers through a PSU calculator, the PSU's I'm interested in might not be suitable because the combined 3.3v and 5v max wattage is lower than what the PSU calculator is giving me as a requirement.

For more detailed reference, the calculator is giving me 130w (but amps is fine) needed on 3.3v and 5v, whilst the spec sheet on the PSU is showing max of 100w on the 3.3v and 5.v.

Should I be concerned about the numbers from the PSU calculator? Or would the PSU (a very high end one) actually be fine? (Vague because of competitor rules, etc)

System is my old 4930k setup. 64GB RAM. RX580 8GB, 2xSATA SSD.

Thanks all.

Went and purchased the PSU as it was something I was after for a while anyway and carefully looking at the recommended PSU from the PSU Calculator, it too only had 100W combined for the 3.3v and 5v rails, the primary thing appears to be how many Amps they could supply rather than being concerned directly with the total Wattage, and so I went with the purchase.
