My questions is, will an EVGA Supernova G2 750w be enough to power the following system:
i5 2500k @ 4.0Ghz (<1.3v)
2x R9 290 Crossfire (Stock)
3x Kraken X31 AIO Liquid Coolers
2x 7200rpm HDDs
6x 120mm Fans
I see this asked quite a bit, but I now find myself in a similar situation, however with a very high quality power supply.
Normally I would just upgrade the PSU, but this a brand new a really high performance unit and I don't really want to upgrade if I don't have to, as I would only be getting an 850w/1000w G2 series anyway.
Would Furmark draw the most power from my system? would this be a recommended test for power stability?
I recall running the same system with 2x HD6870s on a Corsair TX 650w for years without any issues, so I generally don't buy into the whole PSU overkill mentality of buying a 1000+w PSU unless I actually need to.
I would expect the typical answer is an 850w or greater, however I was kind of hoping with such a strong 750w, maybe this would be possible, especially considering the amperage on a G2 750w is on par with a good 850w.
My rough calculations put my CPU power consumption at 100w, overclocked, with my GPUs consuming just shy of 500w at stock, leaving around 100w to power the remaining system components which bring us up to 700w, which seems like it would be within specification with 50w to spare? PSU calculator puts consumption at 700w, although not taking into consideration 3x Kraken 3000rpm water pumps (ive no idea the power consumption on those).
Is there any downside to running a PSU at or just shy of it's rated output over time? given the EVGA unit comes with 10 years warranty, it isn't really a factor, but still I am curious if it is a factor.
