EVGA P2 650w vs 750w?

Good morning PSU masters

I plan on buying either an evga supernova p2 650 or 750.
For gaming with a gtx 1080ti, 650w is enough so either will be fine.

However I have a couple of doubts because both of them are priced exactly the same ($120), and some review sites say that either model 650, 750 or 850 are all equally as good.
But reviews on tomshardware are more in depth, for the P2 650w and the P2 750w.
It says better 5VSB rail for the 650 model, 7.7 vs 10.6 ripple supression, shows better Transient Response tests, and is more silent. (the only worse thing is 17ms only hold up time on the 650 vs 22ms on the 750)


1. Are all the psu's always built equally the same, which means that those reviews are accurate?
2. Does those slight differences between them actually matter? (they should since they are on the pros and cons) making the P2 650 better?
3. Would it be worth buying the 650 vs the 750 for the same price? (yes 650w is enough for a 1080ti but in the 10 year warranty period an average gamer buys new gpu's at least 3 times)

Thanks in advance

I think those variances are well within the tolerance levels with the materials used, and from PSU to PSU of the same model they'll probably vary about that much. I would simply get whichever is cheaper, and if they're the same price, get the 750.

I'm in the same boat and struggling to figure out why the 650 is so much better. Did superflower cut corners on the 750W model or something?

Seems to me that GPU are generally going DOWN in power requirements. Take the last 5 years into consideration... Unless you have some crazy shit going on I can't see the need for anything over 650. 10yr warranty is nice but honestly they fail in the first year or so if they are going to. just my $.02

Depends on the GPU I guess, 1080 Ti uses more power than the 980 Ti. In fact I think it has the highest power consumption since Fermi... (maybe even higher?)
