What about the LED control?

Will you be making / porting (cant be that hard if its C# code) a Linux version of the control center and will you be advertising clear enough at least that in Steam Box form it wont have the full control of the Windows 8 standalone box? (just to avoid consumer confusion / false advertising)

Cheers

If SteamOS allows us, we will. It will retain whatever settings before you booted to SteamOS.

Not sure what all that means... 1U PSUs can't cut corners, since they need to run 24/7, often at high loads.

No...But it maintains the ability to force-draw...Running a Titan on anything less than 500w and I'd call you crazy. It doesn't mean you can't do it, it's YOUR Titan but, you're essentially cutting it down to it's knees.
So 475w at the wall... and with, say, an 88% efficient PSU, that's 413w it needs to deliver. What CPU in the test system? They usually use 130w CPUs for reviews, and bear in mind a mini-ITX-based system tops out at 84w CPUs, due to the lack of socket 2011 motherboards.

Anyway, a bit OT here.

@NavDigitalStorm, will the production version be using a flexible PCIe riser as shown in the publicity photos?

Yes, that's the riser we have been using since the previous Bolt and have had no issues.

PSU efficiency doesn't work like that...Efficiency is in relation to what you draw from the wall not the output to your system.

For example, if you use 300W, but pull 400W from the wall, then the efficiency is 300W/400W, or 75%.

So if you're using 500w, you realistically pull @625w from the wall.

It doesn't go down...

So if I'm using a card that peaks @ load at 475w...And the CPU is using 125w-200w...That 500w PSU goes bum...*smoke*

Again, ultimately, I can't control what people do with their cards but, using a 450w high card in a 500w system, is effectively cutting off the Titan's performance, at it's knees.

It doesn't mean you can't do it but, it's kind of pointless to have a Titan at that point because you've neutered it.

The entire point of this is that a Titan or 290x et al, in a form factor PC is actually a really big deal because it's never been done before. Alienware came close but, was voltage limited...So if DS moves forward with a 700w psu, you'd actually be able to use the Titan @ 100%...Which is a really really really big deal in the tech world.

more a case of Valve encourages development and experiment thumb.gif

You could put your controller code on Github if you want someone to port it (saves time and money)


btw thanks for the straight answers that means a lot smile.gif

I'm saying reviews typically measure from the wall. So if the whole system is drawing 475w, and the efficiency of the PSU is 87%, then the PSU is delivering 413w to the system components (rest is lost as heat from the PSU).

What card draws 475w? That far exceeds what the PCIe power connectors+slot are rated for (2x 8pin@150w + slot@75w = 375w). I think you need to show me a source for this 475w number that isn't just the whole system from the wall, otherwise you're just pulling numbers out of you know where.

http://www.tomshardware.com/reviews/geforce-gtx-titan-performance-review,3442-12.html

Tom's - Max voltage peak was 450w. Average was 410w.

Techspot - 375w-400w

This isn't even overclocked or boosted, this is bone stock.

Most of the reviews rated from 375-425 but, didn't do the same scaling plot that Tom's does.

Let me TLDR this - If you're using a Titan, which at peak consumes anywhere from 400w-475w and you're using this card on a 500w PSU then you absolutely deserve what happens to you when it peaks.

Even on average, using a 400w card in a 500w PSU is...Wow.

Even a 3930k/motherboard consumes 200w-300w...That's not even that high.

What are you going to do? Cripple the system with a 100w CPU and a Titan? Bottleneck, anyone?

I wouldn't even use a 300w card in that system...rolleyes.gif

That's the total system power consumption, at the wall. With an overclocked i7-3970X, which is a 150W TDP CPU @stock. You're really failing to make your point, here.

Let's put it another way:
  • Let's subtract the PSU efficiency loss (85%), so we get a peak draw of 382W.
  • Let's substitute the CPU with one you can actually use in a mini-ITX system (since that's what we're talking about here), a 4770K with an 84W TDP
  • That's a 66W less for the CPU, and we'll pretend that overclocking the 4770K adds roughly the same amount, so we're down to 316W required from the PSU.

316W. You think a good quality 450W PSU can't handle that?
