What PSU for NVIDIA GTX 1080 SLI

[Lodocarbo]

Hey guys I just built a PC (i7 6700, gtx 1080, 650w gold PSU) and I was wondering if that psu (corsair RM650x gold) would do the job with an extra 1080.

Recon that my CPU is locked, so no overclock.

You trying to sell a 850watt psu to a guy who has a 650watt psu already (and a damn good one at that) which will do the job just fine,again imo.Seems that Turkey agrees on that.

The numbers i used are from the gtx 1080 review about the gpu he has,which seems to use 216watts according to TechPowerUp and a review about the i7 6700K (not overclocked) ,pushed to the max,no dedicated gpu and measured for the whole system.If my numbers are well above what it should be gaming then will the OP be fine even more.I agree on that with Turkey3_scratch,but wanted to use peak numbers anyway.

not trying to sell him nothing and did say try to use it and see -- ya he got a good 650w so what if the system was to pull moer amps then the psu can supply that's a issue I showed as a example how to figure that

so his 650 is 54 amps and his system could pull 56 or more its not good enough no matter what the quality of the unit is and he is right at the limit with no overhead room for a sli

I don't gain nothing trying to ''sell'' something so ??? so don't be stupid in saying that ... [a single card a 650w is no problem ]

in the end for all I care is I don't .. I all ready know better as a been there done tried that and learned to have adequate amps overhead like I said if I figured I need 50 amps I get a unit that's 10 or 20 over for any safty buffer or higher end upgrades and when the system need to pull all 50 amps , well its well covered easy cause I got the unit thas got the overhead to handle it no prob ..


you see it here all the time on ''my psu is not good enough ' or card not preforming cause the psu aint holding up tio its needs and so on

so like I said use the 650 [as I did say above and see how it works out may be ok as long as you don't stress it too much or do any overclocking you may find the 650 may sell you short , only time will tell

its not my build so I really don't care that's all your call and headaches

''GeForce GTX 1080 SLI - On your average system the cards we recommend a 750 Watts power supply unit.''

same advice [add good overhead ]

'' also have a 650w PSU currently and no amount of searching has given me a real answer, only strong opinions of others.''

as in better get more overhead

so not trying to sell you anything but the fact the 650w may leave you short all you want is approval on you going cheap and ''get by and hopes ''

enjoy

Look at the review Tom's did,they tested it pulling 715watts and it did fine.It has overhead beyond the 650watt (or 54Amps) continuously that it can deliver.
