Arriving today, can't wait to post up some benchmarks.

Edit : rest of computer

i5-4690k
16 gb ddr3 ram
asus a97
500 gb SSD

I went the crossfire route due to my tremendous success with 2x 660 TI, and I won't be going past 1440p gaming. (probably won't upgrade monitor for a few months from 1080p-->1440p)

Personally I would rather go with the most single powerful card and as far 1440p and a 390 works great.
next year I be upgrading once next gen is out.

It does have 2x PCI 8-pin connectors so i'm good there, and my sig is up to date. Thanks in advance for any help.

Check out this to find your power usage

Now you might see spikes of power usage sometimes that go really high, but those are momentary and you shouldn't pay attention. I'd think all 390 cards will consume roughly the same amount of power, seeing as the core is unchanged. When variations in voltage and clocks are taken into account, of course.

Regarding overclocking at stock volts... Don't even factor that into your decision. It's 100% random. Some say the MSI cards tend to overclock better, but I'd say no. It's random as always, as is overclocking in general. You can expect something in the 1100-1150MHz range at stock volts, most cards do something like that.

Also, what do you mean about seeing an increase in voltages from a stock configuration overclock? The way I understand it is you want to know how far you can push your overvolt/overclock at with stock cooling? If so, the Sapphire cards arguably have the best cooler. Throw +100mV at it (The max Afterburner allows) and it's still ok. The MSI cooler is really good too, but MSI seems to have screwed up with their TIM application, so be aware of that, especially if, like me, you don't like tinkering with your shiny new card. XFX and Powercolor are fine choices too. I would just stay away from Gigabyte for the 300 series. That cooler of theirs seems awful and they're voltage locked, so... Yeah.

i figured it could be due to the cooler that th sapphire one used that much power. And it was the numbers listed here. keep in mind it's a norwegian site. I cross checked it with other places, and turned out nobody had anything, so i asumed the worst and decided to ask.

Yes, that's hat i meant. How much i can safely increase the stock voltage. And thanks for the lengthy answer. It's easy to enable voltage controll on them, right? my current saphire radeon 5870 seems to be voltage locked (done what's needed in msi afterburner, and even tried flashing the bios), so don't have any experice with it.

The reason i was asking was because I am planning to crossfire two r9 390 later (ie build my rig to handle it, get one card now, and one later on) and i was torn between an 850 and a 1000w PSU. With all bone stock, a CF setup sits at 700w powerdrain. I asume a 1000w one would be better for overclocking if i'm running crossfire? Or will the evga super nova 850w g2 be enough? If not, i'm considering the 1000w one.

Check the link I gave above. To be on safe side you will need 1100 W. I am going to get 2 sapphire R9 390 myself, ordered one for now.

been there, checked it allready thumb.gif
Unclocked i hit 708w, and given how each card can be clocked up 100w or so, it'll hit 900ish. Add in some CPU clocking (won't touch power clock) I'm just a bit unsure on what to go for. A 850 one is too weak, that's clear. But will 1000w be enough? the prize gap from 1000w and over is HUGE over here. But hell, i guess the supernova g2 1300w will last well into the next ice age. And it gives plenty of leeway for casemodding, and putting in excessively high number of HDDs biggrin.gif

It should be plenty. You won't be adding 100 watts to each card with overclocking, as with 2 cards, unless you have insane case airflow your overclocking will be more limited by heat.

Just a warning, unless you know something I don't tongue.gif

Check alpha cools configurator. It's the gpx 390 m02

I will personally go for a antec/cooler master 1500 W. I am planning to add 3 sapphire in one for 3D rendering in Blender.

So if you ever wanna go 3 SLI, keep that in mind.

They weren't listed on modmymods when I purchased them. Thank for the concern though

A corsair H60 CPU cooler (don't need more for intel) in push-pull config, slight overpressure on the case, and a fractal define R5 with high effect noctua fans (up to 140 cubic meters per hour). Doubt i can get it much cooler without watercooling, or without getting fans sounding like a hunter hurricane taking off biggrin.gif
Obviously won't use all the fan slots, biggrin.gif as that would get my pc dangerously close of generating enough lift for takeoff biggrin.gif but i'll make sure it's running cool enough.

So a 1000w one is enough?

problem is just in 3way crossfire i will be broke as hell, and have an F35 jet engine. seriously, you can't realistically keep 3way sli cool without waterblocks. At least not overclocked XD
So even 2 way crossfire is future proofing by my standards.
