AX860i or AX1200i

Hey guys,

In my new rig I am planning on overclocking an i7 4790k to around 4.6GHz, and eventually will have Titan X in SLI, now from what I have seen the CPU power draw at load would be roughly 110-130 watts, and under load a single Titan X can reach nearly 300 or so.

My conundrum is this, do I go for the 860w or the 1200w psu. I understand PSUs are generally more efficient at 50% or so loads, and by my reckoning with an overclocked CPU and 2x Titan X overclocked plus my other peripherals would be pushing that quite close to 860.

Should I grab the 1200w and be done with it or would I be fine with the 860w.

Thanks
 
Firstly, the Titan X graphics cards wont be drawing anywhere near 300W, more a around 240 or so even after OC. generally it would be even less. Then again, this would depend on the extent of the OC.

Either way if you dont plan on upgrading I.E adding another card and dont want to spring that extra dough for the AX1200i, then go for the 860W. Though if you are even considering upgrading to 3, definitely go with the AX1200i, As the 860W wouldnt be able to handle the extra.

Nonetheless, if you can afford to pay that little bit more for the 1200i, definitely go for it. No point cheaping out on the PSU after spending that kind of money on your other parts.

Just because things are getting more efficient, doesnt mean there wont be high end parts that will use more power. More performace = More power (of course if its comparing the same arch)

Thanks for the swift reply. Yes eventually I am planning on a 2nd Titan X later for 4k excellence, so I will go for the AX1200i, which I see you own as well according to your signature.

Next challenge is the monitor, I think for now I'd best go for Acer’s XB270HU, looks a decent 2k IPS 144hz panel, should suit the single Titan X for now, then when I can get that second Titan I'll upgrade the monitor to a decent 4k 120hz IPS monitor at the time.

Do you really need the digital thingy? Because the RM1000 and the suferflower leadex 1000W variants are solid performers for that Wattage!

This is what I use with my Titan Xs.

A little bit of overkill but the PSUs run at their most efficient and very quiet as most of the time the fans don't need to spin up.

Well dude... you're Kaapstad with Titan X's, we all know it so don't need another copy cat Kaapstad ^_^

I've said it once I'll say it again Kaap.

Your girfriend or wife must just look at you sometimes and shake her head ^_^

Right now, I have neither girlfriend nor wife to shake her head at me. Heh.

Btw, 4.8 overclock on that 4790k is nice, how'd you achieve that and what are your temps?

Haha, can see that picture :lol:

Cause he's Dice, he simply rolled the dice and bam it happened... pure luck if you ask me :p

There are FAR more expensive hobbies ;)

Haha yeah, you'd know dude :lol:

I actually bought it cherry picked from a local store, Paid a bit extra over a non cherry picked 4790K.

Temps are low 30's idle, Usually hovering around 31'c, Load is around 78'c but that's 100% load, In games it's usually mid 40's depending on the game.

And volts used are 1.30v :)

Damn right !!! ^_^

Looks like someone lucked out on the old silicon lottery, you cherry picked the stepping I take it?
 
I have seen some folk not be able to achieve 4.8, usually managing around 4.6 or 4.7 stable, what do you attribute your stability to? I am planning on using a h100i GTX cooler on my CPU so should have some decent overclocking room. I also am about to fit some corsair AF120 performance fans in the case, airflow will be pretty damn good.

Lets hope I luck out on that silicon lottery too :)

I attribute the stability completely to buying a cherry picked CPU that doesn't need a lot of volts oh and living in an extremely cold house helps too ^_^
