GTX 570 SLI with Antec EarthWatts 650w Power Supply

After reviewing two GTX 570s I decided to pop them both in and test the mettle of my 650 watt Antec Power Supply. I also check out some SLI scaling in this video.

Could you test your single & sli 570 setup, with BF BC 2 & Metro, at 1920x1080? I'm wondering if you get micro stuttering as well?

[ragejg]

@ZzarkZul I never seemed to have any microstuttering with that setup. Currently I don't have the 50s any more. With teh same PSU.mobo etc I overclocked an x6 1090t to 4.0 ghz and have two GTX 560 regulars at 925/4250/1.087v. Only microstuttering I've encountered was in BF3 beta where it was 10-15% measured using rage3d's tool.

nice work buddy, but i have a question, can i use a sli of gtx570 *without overclocking with amd x6 1090t 3.2, using one of these CORSAIR 750 watts without botleneck or i can fry something using this energy source?.

[ragejg]

@brunobmb7 If I could do it with a 650 that's probably not as good of a PSU as your Corsair, then I don't see why not.

[MrShadowhearth]

are you still running safe setup on this m8? i want to get second 570 for myself and i got 750w psu.

[lars38010]

very weard 650 watt can power 2x225 watt + 300=750 so how 650 watt psu can handle this?

[tiwer1]

which 570 card model was this? i was gonna try an sli with 570 2560mb for just 1 day. had a fan noise issue on my card, so i did an rma (temps r fine), it is to arrive today then i send mine back. Thought I would sli for a day, never done an sli setup and was kind of curious. i have a 750 watt thermaltake psu. also was just curious how long you ran the setup like that for. i will take the overclock off of my 2600k and not overclock the vid cards, so everything would be stock for the day. thx

could I SLI safely with a Corsair GS700w psu i5 2500k cpu

[buzz9961]

your gtx 570 in sli runs fine you dont havr problems

[BIGTAMISH]

Heya, im using fractal design 650w psu, and im thinking of going with the 550ti SLI solution.

Im just wondering if my psu will be enough for 2 st zotac 550ti. Answers are very much appreciated! :)

@JohnDoe7767 I would say its safe altho its around the mininum recommended wat amount.

[JohnDoe7767]

After seeing this .. I would think its safe to say my Seasonic x750 Gold would be just fine running 2 evga 570 SC in SLI, even with a 2700k OCd to 4.6?

[acemace3618]

@acemace3618 Oh, well......cool so I can power it, thanks for your time

[ragejg]

@acemace3618 Well, for comparison's sake I had one optical drive, one SSD, two old WD2500KS drives in RAID 0, six 120mm fans and two CCFL tubes.
