NCIX says I should get a min. 750W for Titan Black and Haswell??

[AznKnight82]

I ordered it with a be quiet! Dark Power Pro 550W (Seasonic OEM with better capacitors and quieter fan). Now, from my knowledge, and everything I've read in these (and other) forums, 550W (with a 610W Peak) should be plenty for: 

 

• Asus Maximus VI Impact
• G.Skill RipjawsX 2x8GB 1866MHz
• i7-4770k
• h100i
• Noctua NF-F12 (x2)
• Corsair Case fan (x1)
• Samsung 840 Evo 250GB
• WD Black 1TB
• eVGA Titan Black (ordered the ACX cooler from eVGA too)

 

 

I was talking with NCIX support since the eVGA Titan Black is now back-ordered (I might've gotten one of the last ones, for now). He was telling me that "Nvidia recommends a minimum 600W power supply for the Titan Black because that's how much power it uses. The 250W rating is for the power draw at idle."

 

This goes contrary to what I know.

 

I told him to build it "as is" and tell me if there are power problems (I paid for the premium assembly + 1 year warranty).

 

This would also go contrary to mITX cases with custom PSU's installed (like eVGA's Hadron with the 500W PSU).

 

 

Should I be shopping for a bigger PSU?

I would say go for an AX760.

[CoolBeans]

650 should be fine

[Commander_Z]

AX 1200i

[Shrubpig]

I would go with a 650W one

 

@Commander_Z there is no point to get an AX1200i

550w should work but if you OC it's cutting it close.

600-650w would be a solid amount of power for your system.

[Antistatic12]

Go with what Nvidia says. It is their card, you would expect them to know about it the best.
also
A 4930K or 4960X would be more fitting for a Titan Black. Unless it is just being used for games. In which case I guess it s fine.

So the general consensus is that 550W is not enough?

 

I like the be quiet! for the acoustics. The 550W is 14dB under 100% load.

 

The 650W is back-ordered on NCIX. There's the 750W (gold+ and $40) and the 850W (platinum+ and $90).

It's a mITX build. This was my "budget" build for Cuda compute apps. And some games.

You could go with the RM650 if you're worried about noise

[quan289]

The BeQuiet DPP 550w would be enough for a i7 4770k and Titan.

ahh ok. Go with what is in your means.

The 250w for a titan at idle is complete bs. That's actually the max tdp. If you oc the card, it might get a little higher, but generally even at load consumption says under the tdp. 550w should be enough, although it won't leave a lot of headroom for your build.

Nvidia is assuming you are going to be using some middle of the road piece of crap power supply.

You will be more than fine (see video below)

That was my understanding of NVidia's rationale, too. A lot of people have said that in the past.

 

I don't know why they would do that for their flagship product. Anyone dropping over a grand on a single GPU should be able to afford a brand-name PSU. But I dunno. Some people are stupid or like challenging big companies. 

 

"You said 400W is fine, but the 400W PSU I made in my garage made my Titan Black crap out!"

[needmorewood]

if u get a nice PSU u could probably go 600-650 and still have a tiny bit of headroom. 

[ooiman92]

Bonsai beat me to it, we now have video proof that you don't need an over the top power supply for today's computer builds unless you're going for silence.

Even going with a black titan and overlocking the 4770k like crazy won't get to 550W. The be quiet! Dark Power Pro 550W is going to have about 100W headroom. It is plenty for the system. Going over that is not smart spending.

Watch the OC3D video that bonsai99 listed, and if you don't trust Tiny Tom Logan (great guy), trust Linus, he is running a GTX 780, and a 4960X AND a Quadro 4000, with a 550W PSU. Here is Linus post and part list, check it out: http://linustechtips.com/main/topic/57755-ghetto-build-log-edzels-video-editing-rig-upgrade/ He is using the exact same PSU that you want.

550 is pushing it, I would go go 650

[AznKnight82]

As a side note, I don't plan on doing any crazy OC-ing. Moderate OC-ing, more on the GPU-side than CPU-side.

 

This system is crammed into a Corsair Obsidian 250D.

Well that is very interesting. After watching this video I feel comfortable going sli with my 780's on 750w. I'm still going to purchase a killawatt meter to make sure but I am really not worried now.

[AznKnight82]

A friend of mine linked me this:

 

http://www.thermaltake.outervision.com/Power

 

I ran the numbers and compared it to OC3D (I used the 780ti since the Titan Black isn't on it yet), and I OC-ed the CPU to 4.4GHz, and still under 450W.

 

Nice. 

[AznKnight82]

So iffy. They sent my another warning today.

 

 

I see the order that you have in place. I'm concerned about the amount of power you selected with your build. I also see that you discussed this issue with one of our Customer Care agents and he advised you of the same. 

 

We'll build your PC with the 550W you want to use but please note that if your computer fails testing, you're looking at an extra 4-5 business day delay on top of the regular assembly time of 4-5 business days. The reason being is because if the PSU fails under load testing the technician will have to dismantle the computer and cut all the cable times and redo all the cabling for a replacement PSU.

 

We strongly advise that you select at least a 650W PSU but if you understand there may be delays if your computer fails testing we'll attempt to build your PC with a 550W PSU. 

 

Have a great day

550W is more than fine. That 600W minimum applies just to shitty PSU's and basically works as a disclaimer.
