Which PSU between these two?

Thanks, they cost the same and I am going to use them for r9 290 crossfire

Which ever is the cheapest, since they aren't it's all about the aesthetics.

Between these two I'd pick the EVGA, but 1kW is overkill for crossfire (if you are not going for three cards)

EVGA's because the two are pretty much exactly the same including stuff that's not just listed on a spec sheet but the RM series from corsair use rifle bearings instead of dual ball bearings. Dual ball bearings carry better longevity and performance. Dual ball bearings also costs more but these PSUs are priced the same on the site you gave us. Plus, and I'm not 100% on this but the EVGA Supernova have all Japanese capacitors whereas the RM1000 has only Japanese capacitors on the primary capacitors. Oh and if you don't know Japanese capacitors are the best. By the way it is generally known that the secondary capacitors on the Corsair RM series kinda suck.

Oh wow, I guess I've underestimated the power consumption of AMD...

Do you have red in your build? I'd pick the evga because I don't like corsairs sleeving on the rm series. It doesn't really play nice.

I have red extensions, but I'm gonna go with the EVGA one anyway

Nice, thank you

EVGA. Better internal components, higher operating temperature, better fan, longer warranty, performs better electrically.

The 3 people I take seriously on this forum regarding power supplies: 1. quan289, 2. WoodenMarker, & 3. atrash. And again, atrash hits the nail on the head. G2 > RM.

@Laforet They are not the same.

@Paralectic s3ns3 is correct. The RM Series is an unimpressive mainstream series, made by CWT/Chicony, and using Ltec and Capxon secondary capacitors. The performance is not as good as the Supernova G2.

[ForsakenLive]

Evga all the way

It says it is nvidia Sli ready, but it is crossfire ready as well?

I don't think there are any physical changes that need to be made to support SLI/Crossfire with power supplies, and maybe also with motherboards. It's just that SLI certification costs money while Crossfire certification is free. That's why my GA-Z87-HD3 motherboard is Crossfire and not SLI certified. Cheaper.

If it is SLI certified, it should be Crossfire 'certified' also. Should work.

Tbh, it makes no different with that sli/crossfire certifications. As long as it has enough pcie connectors and amperage for the graphics card,then the psu is both config 'ready'.

 

@daemonowner haha nice location tag on your profile.

[daemonowner]

@atrash Yep lol, just changed it. I thought it was fitting given how I rant and suggest anything but the RM Series whenever I can.

Noo..Corsair makes the best of errryything. If it works fine for them, it means it is THE best and none shall top it. Do not fight the marketing power,mang.They are too strong..LOL

[Faa]

You rather get the 1000 P2 instead of the G2 for the semi-passive fan. But like many said here you don't need a 1000W PSU to fire 2 290's in CF

SLI certification on psu's just mean that the pcie connectors need to have their own 12v rail. So basically if you have two +12V rail's - Rail1 carrying CPU, motherboard & GPU's - Rail 2 doing hdds, fans, lights eg that wouldn't work in SLI. The pcie connectors should be moved to the 2nd rail then SLI would work.

So you just read the first sentence and not the rest of what I posted. I already mentioned the problem with the secondary capacitors on the RM series and mentioned the fact that the fans are rifle bearing whereas the Nova is dual ball bearing. I meant they're the same in other areas including efficiency rating, layout, wattage etc. I was talking about the PSUs spec sheet wise. I still brought up all the crap on the RM series. Although I could've probably phrased it better. That aside I couldn't really affirm the stuff about the RM having crap secondary capacitors because I can't remember where I learned that so yeah pretty much explains my post.
