No 780Ti for me:(

RetrogamerX · 12 Apr 2014 at 18:55

God damn it. My Corsair AX850 PSU just died :mad:

No new GPU's for me until I get new PSU

Using a 600watt crappy OCZ PSU for now until I get new one?

Want to power 2 780Ti SLI.

How's this PSU?
Corsair RM Series RM 1000 80+ Gold Rated?

I like the SuperFlower Leadex Platinum 1000W, but I have to use there cables. I want to use coloured cables and it seems only Corsair do them. Is that Corsair RM 1000 a good PSU? or maybe the AX860i? Which is better for 780Ti SLI?

Thanks

I can't see you going far wrong with that Corsair psu (though I have to admit I'm no authority on power supply units).

The Corsair RM series is not the best. Similar for AXI sadly. AX series was great. They changed OEM not for the better.

You wanna OC 2 780Ti you need SF 1200 Plat or similar. Would have to use extension braided cables like you say. EVGA, Seasonic and Bequiet are also top supplies.

I bought a Be Quiet psu quite recently, and it's been good. Shame about the Corsair.

Enermax are excellent, too.

Now things like this worry me, I've not long invested in a Corsair AX1200i and full kit of colour cables, what is wrong with the AXI supplies? I've just spent a small fortune on mine, is it being said that a 860i wouldn't be sufficient to power two 780ti's?

Wouldn't the SuperFlower 1000 watt be enough?

I also like the EVGA SuperNOVA 1000W 80+ Platinum I think 1200 would be a little too much I'm only going to do small OC's. so if I want colorued cables I'll have to use BitFenix Braided Cables I guess.

EVGA or Superflower?

I have 3 Titans and a 4930K all overclocked and all running off a 1200i, rarely see more than 900-950w at the wall

The 1200i is ok with up to 3 780ti's (providing you are not trying to drain the national grid like 8 Pack) but when running 3 290Xs and a 3970X overclocked it could not cope in my system.

As 8 Pack says above, there are better PSUs around for heavy work.

3 Titans was no problem on mine either, I did see over 1100w at the wall when I was doing some serious benching.

Looks like the AXi use Flextronics who are pretty average (nothing wrong with them - but not as good as seasonic, etc.). 860watt should be ok for 780ti SLI unless your using a custom BIOS to push massively past the normal power targets.

I like that one too. It lights up too... Will have to wait until end of month. Upgrading in may with the haswell refresh 4790k. So will live with the ocz psu until then.

Cheers Neil and for everyone's input

I couldn't run a Titan @ 1306 with 1.3v - went thru 2 AX1200i

Both would just shut down

But they would run 3 x Titans on a stock bios without issue.

A lot of people have had issues with AXI PSUs myself included. As soon as I got back my 860i from corsair rma I sold it on, looking at getting the standard AX 860 now that has way less issues, I put this down to fact the 860 is built by seasonic, whist the AXI is flextronics.

An 860 is more than Enough for 780ti SLI, hell OC3D ran a ti with a RM450.

It may be a volts thing, I was using around 1.375v with my 290Xs when my 1200i shutdown.

Here is how I solved my problem with the 290Xs.

I feel your pain but is your PSU out of warranty Retro? Might pay to use the OCZ for now and RMA your Corsair.

systemerror · 12 Apr 2014 at 20:04

I just bought the super flower 1200w platinum psu and am very impressed with it.

Thanks for reassurance and kaps post too, not going to ever go more than two cards so I should be fine then, just wondering if a 860i would still be enough for two 780ti's?

PSU is just over a year old. Will call ocuk for them to RMA the PSU. Will buy new one before I upgrade. Which one do you have Greg?
