GamePro gets 360 Debug kit (power supply?)

There are nowhere near enough vents in the prototype PS3 pics that I've seen posted on the net.

Either we're missing some angles, or they're going to add more vents on the final console.

I'd guess there will be vents in the bottom as well. Check x360, you'll see there are vents there, and the rubber feet lift the console a couple mms off the surface it stands on so that air can be drawn in.

There's also the possibility one or more of the sides of the PS3 casing is made out of some alu or magnesium alloy to act as one big passive heatsink, like many laptops are, though I wouldn't expect it...
 
I believe it's a prototype, Shifty. If recall correctly and I never do, the XBox 360 at one point had an AC plug too, though that was long ago. Anyway... from what I can garner, which isn't much

BRD -- 20 watts -- This is based on the Blu-ray spec... may have changed by now though.
CELL -- 40 watts -- A 4GHz CELL was supposed to be around 80watts, so 3.2 and a disable SPE should be a good bit cooler, especially since the volatge ramps down pretty dramatically.
RSX -- 60 watts -- G70 is 70watts as it is now, add some MHz and a process shrink and something along there sounds OK... like I know what I think I know I'm talking about or something... ( >.>) (<.< ) ( >.>)
System features -- 10watts -- Last I heard things like Blue Tooth were very low power and I can't imagine the other innards taking up much.

Grand Total -- 130watts. Kinda scary. Thankfully it's just guessing.

My PSU on my PC is 500Watts, i'm also pretty sure its consuming around 400. I cry whenever I have it on (not in the joyfull happy way).

150 watts worst case then probably. And XB360 can't be any more than that. What's the smallest (economical) PSU fo rthe job? My Googling was useless
 
My only concern is how hot will this thing get? Laptops use external power adapters and they run hot as hell. Holding it in your hand could burn you. The back of my entertainment center is kinda cramped and sometimes paper is behind it and I don't want it to be a fire hazard.

Anyways, it's huge but at least it's not internal. The 360 would need to be the size of a PC.

Right, not to detract from the silly talk, but i'm still not sure why this thing is so bloody big!

I mean i have a 450W PSU in my PC, and i really really don't think the X360 PSU will be that powerful, it just doesn't need to be. My 450W PSU is a standard sized PC PSU, which is much smaller than that Ghostbusters trap.

My LCD screen has an external PSU and it's rather small, surely much smaller than the trap.

i just don't know why this thing is so big!

The fact that it's passively cooled means the volume has to be large enough to displace the heat. If your PC PSU running at 450W didn't have two fans, it would nearly be half the size of your case. I won't be surprised if the "brick" is actually pretty light as most of the surface area is used to diffuse heat.

They (both MS and Sony) also need to handle power to the HD which is going to be another 10-20w (higher on spinup). The big issue is that they want a consistent power supply more so than a big one. They'll probably be fine with ~160-180w, but they'll want nice consistent rails, and that comes at a price too.

Edit: Forgot they are using a 2.5" disk. That should be lower power, so maybe 150-170...

If the PS3 is standing like the picture above the vents on the bottom would be blocked, the only vents that can flow are up by the BR drive, leaving no vents down by the CPU and GPU????

I thought the same thing when i saw it. There will probably be more vents behind or on top somewhere on the final unit.

Yeah i was thinking that while i was typing (quite intuitive really), but thought i'd just finish the post... err..

I noticed your edit, and your figures are still way off. Modern desktop drives don't even draw 10W, and much less 20! Check Seagate's site, the Momentus (which is what we'll see in x360 from what I've seen on the web) draws 5W on spinup, less than that when idling. Power draw and heat is essentially negligible where a 1-platter 1-head 2.5" drive is concerned, and even if it was 20W on spinup, you're not going to have either CPU or GPU running at full tilt during system boot.
 
Better picture of the PSU's compared size in relation to the Xbox 360.

Wow!
 
PS3 has an Internal Power Supply?

Q. Considering power of CELL and GPU, the case size, and the internal power unit, it seems tough to manage heat. How is the noise?
A. Since quietness is very important, our hardware team is trying to make it as quiet as possible. Of course it has all power-saving efforts in the chip-level. Though it’s not compared with PS2 yet, I’d like to make it more quiet in the final product.- ps3today

It would be pretty amazing if this were true.

Note that the interviewer acknowledges that managing the heat would be "tough" with the CELL, GPU, and the power supply inside the small PS3 case and Chatani responds mostly to the interviewer's last question regarding noise. Was he dodging a bullet? Most likely.

Still he doesn't deny that there is an internal PSU and he appears to touch on the heating issue a bit when he says, "Of course it has all power-saving efforts in the chip-level." And I wonder where the interviewer got his information. Perhaps he was just making an assumption.

My own personal conclusion, based on what appears to be an obvious dodge by Chatani, assumes for now that the PS3 will sport a nice little external brick much like the X360.

Well, I was right in my guess of a ~200 watt max power draw. Damn but I'm good. ;)

Nice find by the way Hitman - welcome to the forum.
 
yea;) i registered to give u that information;)

By the way... i've all the pictures of the Dev kit that where released by smartXX... i saved them on my HDD before the where taken away...

That pic you posted has made the rounds on this site at least once before, but I still thank you for your effort. :)

The pic of the smaller powerbrick is almost certainly for a flatscreen. Look at it, you'll see there is no grounded powerplug attaching to it. Any major computing equipment is almost certainly grounded these days. Besides, its size looks disproportionally small compared to the power draw x360 is certain to have. Though the giant brick looks disproportionally large I might add... ;)
