Corsair 750RMi vs EVGA 750w G2

[Rifter]

Which would you pick for a new ryzen build? Both looks like solid units. Build quality maybe a little better on the Corsair unit. But the Evga has platinum rating vs gold for corsair. Corsair also has a nifty monitoring program to tell you loads and efficiency in real time.

Im leaning towards the corsair but looking for any input you guys may have.

My 8 year old Corsair 850TX is still going but dont want to rely on it for my main rig for another 8 years. Its also making a wierd humming sound now when PC is turned off which is a little concerning as it never did this till 2-3 months ago lol.

Corsair will run quieter, starting from when EVGA turns its fan on. But with EVGA you can toggle ECO mode (or zero RPM mode, or 0 dBa mode, semi-passive mode, whatever you want to call it). Other than that there's no practical difference between them. Same reliability, efficiency, warranty etc.

Are you sure you need 750 watts? Ryzen isn't that power hungry, and if you're only going to run a single GPU, you'll be fine with 550-650W.

Also, why not consider other units as well? EVGA G3, EVGA P2, Corsair RMx, Seasonic PRIME, Bitfenix Whisper?

Im planning to upgrade to vega or another bigger GPU at the end of the year/early next year so want some extra PSU power for that, also want to make sure ive got enough grunt for a max overclock of zen2 as im getting a 1700 now which i know is very power efficient but may upgrade CPU only to zen2 next year if it offers greatly increased performance, and if AMD goes to a higher power process for that it may well draw 200 watts overclocked to the max. So just want to cover my bases with a larger PSU.

Ive looked at the RMx but its so close in price to the RMi that i believe it would be worth it to get the RMi.

bitfenix is hard to find around here, seasonic looks ok but usually a little more money than corsair/evga. ill go with whatever is cheaper onsale at the time, as im in no hurry to buy.

EDIT: just realized thread title, meant to say P2 not G2

@Rifter I'd still argue that 650 watts is easily enough for any single GPU card, even Vega or 1080 Ti, and even with a CPU that peaks to 200 watts. But I'm highly skeptical that Zen 2 will allow for 200 watt power consumption under any scenario. This is not the old FX we're talking about, this is the architecture that beats Intel i7-6900K in performance per watt, and even that CPU just barely exceeds 200 watts under torture testing at the 4.3GHz peak OC.

250W GPU + 200W CPU + 50W other parts = 500W -> 77% of 650W.

I suppose the only argument for 750W is it may run quieter under load (depends on the model too; RM650x/i will be quieter than EVGA 750 P2/G2/G3). And cost, of course... if it's just $5-10, who cares.
