YES, Your Shuttle PSU can handle it! (post your specs and what PSU you're running)

[gerily]

My power supply can handle it now!  :-)  This is my first shuttle system and my first time here! I'm loving my SX38P2 experience. From day one I couldn't stop tweaking this lil box. It's a great platform. Wish there was a sticky'd thread for modding it!

Though the noise from the factory 450 watt power supply was killing me. It may handle my system but, I couldn't handle it! After researching the options, I decided not to down grade to a 400 watt supply. Not when I wanted to put in a 9800GX2 So, I decided to mod the case instead. Besides the welcomed extra 200 watt's of power, comes the quietness and extra cooling from the new PSU. It's whisper quiet now. I actually have to walk over and lean in to hear if it's running.

For everyone trying to find the breaking point of the stock PSU, it's only a 16a rail. If it was a single railed power supply, then it could easily run a 9800GX2. But, it's a dual rail with 16 amps running to the CPU and the other 16 amps shared between the video card and peripherals. 192 watt's isn't enough overhead to continually run the card and components long term. That's just begging for something to burn out. And, the PSU is the cheapest component in the system that could burn up. With a $600 video card going in, I'm not going to chance it.

For those looking at total wattage, YES, the total wattage of my over clocked Q6600 and 8800 GTS is only 255 when pushed. It's a great setup for the 450 supply.

The only thing I was considering using instead was a 650 watt Ultra Power supply. I love there Flexible cables!!! Would have made the install easier. Also, Tuniq makes a 950 mini plant that fit's and is quite. But, no modular cables at all.

umm... maybe it´s just me but why isn´t this mod getting way more attention?  this is probably the most significant and impressive mod i´ve seen done to a P-chassis

I did a similar mod to a SG31G2 back in late march.

removed the drive bay and notch the face a bit so that my CORSAIR CMPSU-520HX ATX12V  would slip right in between the support bars and exhast where the 5.25 and 3.25 were.

Don't think i don't have a dvd drive either.  I have a ide cables coming out the old psu hole (can tuck them in) so that when i need to install OS or games I can.

I will say i also have the dual slot 8800 mod on this case which combine with the 120mm psu fan there is bearly any heat inside the case.  Surpisingly 8800 is slient while inhaling and exhaling outside the case.

Don't have any pic on hand but i could borrows a friend's 10mp camera sometime.

BTW if you want to build one with about the same specs from newegg for earily 700's  more if you want to get a more updated Card.

Using the same components in another system with zalman fan controller, not more than 270W full load.
I reckon even a 300W powersupply will do just fine.

fan of the PSU 450W is too noisy. Thinking of modding the fan, but as far as I can see, can't do that without voiding the warranty.

I've just done the upgrade that I've been planning for a while.

SN95 v2 BOM21

3800 X2
2Gb OCZ RAM
Pioneer DVD RW
Sapphire 3850
Seagate 250Gb
WD 120 GB
...and just to be thorough a Logitech Bluetooth KB/mouse, Fang gamepad and a joystick all hanging off the USB
Stock 240W Shuttle PSU

Works great. XPC tools reports System 49C, CPU 40C and Board 42C all measured on a cool day in Perth Au winter. Adds about 6C after playing BF2 for a while at highest settings.

During the upgrade I also replaced the SATA cables following forum suggestions that these might be flaky. It seemed likely after the second HD "failure". Previous machine cold boot problems also experienced. All now running fine (with same disks also restored to usage after corruption issues resolved)

I was totally surprised that I did not have to replace the PS on this system after upgrading the processor and videocard (these came from my old system, which has become a server now. Did a swap there.). Although this system is not really stressed, I have run some games on it like UT 2004. That gives me no problems. The only limitation in power is that supplied through the USB ports. I cannot run my Western Digital Passport drive stably on either of them. The solution was simple though: a powered USB HUB.

Despite the claim on the product web site (still unchanged) that this Shuttle supports RAID and despite the promise of support that there would be a solution last week, there is still no solution to run RAID on this model.

I am particularly dissappointed in Shuttle that they know this for a long time, make an almost hidden faq with a statement about the Intel chipset, but do not update their product information on their site.

If people are saying that the 250W psu in the SG31G2 can run a Q6600 and an 8800GT then do you guys think that a 300W could handle an E8400 and a HD4870 or maybe the Q6600 with the HD4870?

The SG31G2's stock 250W is barely enough for a Q6600/8800GT combo so theoretically an E8400/HD4870 setup would be fine with the upgraded 300W PSU from Shuttle, but I'm gonna be picking up the Thermaltake Toughpower Express 450W PSU to power the HD4870 alone...should work out nicely.

yeah..
I was reading on shuttle website. I saw that SD39P2 handle HD3870X2.
So, I can trust that it's handle 4870 too, 3870x2 need much more from PSU than 4870 single.
I'll not change my psu. unless it burns

I dunno if I'd go that far but I do agree...should be fine if it's rated for the 3870x2.

I guess I'm just a little confused.

I ran the media center I'm building through a PSU calculator and it suggested a MINIMUM of 500W.

Sapphire Radeon HD4850 1GB

INTERNAL 23-IN-1 USB 2.0 Card Reader
2X BLU-RAY/HD ROM, DVD-RW SATA
PF27 Display

1TB External HHD
Bluetooth Keyboard and Mouse

But I see that the highest wattage PSU Shuttle sells is a 450W.
Does the SFF Mobo take that much less power?
Or should I invest in a different PSU?
Will standard-sized PSUs fit in a Shuttle, or do I need a SFF-specific model?

Thanks for all your help.

edit: I just ran a more sophisticated calculator, and came up with closer to 315W.
        Is this a more realistic number? The Shuttle comes with a 300W, so I'd still have to upgrade.

Don't assume that you'll automatically HAVE to upgrade because an online calculator gave you a number like that, take more time to ask/look around this forum/thread and see what kind of systems people have running (long term and fully stable) on Shuttle's own 300W PSU's...I'm sure you'll be pleasently surprised.

Aside from the topic of whether or not your system would run on the H7's 300W PSU, let me address a few of your other questions:

1 - Shuttle's 450W PSU does not fit your H7 system that you intend to build, the 400W/450W are completely different sizes and are built to fit the P2 style XPC's.
2 - Technically the Shuttle PSU does draw less power then a standard motherboard because of it's smaller size and the fact that it doesn't physically have as many components on it, but I wouldn't say that the difference is a really huge thing.
3 - With Shuttle's G2/G5 (and I'm assuming H7) families of XPC's the highest wattage PSU you can attain (last time I checked) is the 300W that's already included in the H7
4 - Standard ATX power supplies will not fit in the G2/G5/H7 Shuttle systems as the PSU's are installed on the side of the case and are very thin. The only Shuttle systems that can physically handle the size of a normal ATX PSU are some of the newer P2 models, then you've got to start looking into wire management even if you do go with a modular PSU, as there ends up being next to no free space inside the system and your temps will suffer. So yes, with the G2/G5/H7 Shuttles you typically are limited to their PSU(s) but I believe there might have been someone who posted a link to a server style PSU of the same dimmensions that should fit...but there wasn't much of any difference in wattage, it was just an option.

Again, I'd take those PSU calculators with a grain of salt when designing/building a new Shuttle system, as the calculators aren't really meant for that specific use and aren't as accurate as they are for full size ATX systems.

I'm sure if you scroll through the dozens and dozens of posts in this thread you'll find a good number of people who have a Shuttle built 300W PSU with a variety of different system configurations...and I'm sure you'll be fine.

I know that I've seen people put more power hungry video cards in their Shuttles then the HD4850 and get by just fine, and there's nothing completely out to lunch about the rest of the system you're planning, so I wouldn't worry about it.

Hell, go ask around other forums if a 3.1GHz Q6600 quadcore CPU and an HD4870 will run on a 400W PSU with a single 12v rail that has less then 25A and see what people say...then look at my sig.  ;-)

These little boxes are built very very well, and the PSU's are incredibly capable. There's almost always someone available around here to sit down and talk you through a decision or issues you might be having so don't forget to ask ask ask.

I got an ATI 4850 working, but only after I tried several different combinations of molex plugs to feed the y-adaptor to the graphics card.
Otherwise, I had reboots and problems warm-booting or restarting.  Since I split the load, I've had *zero* problems. I turned the system fan up to 2k RPMs to keep things cool, and setup some custom CCC XML profiles to spin the GPU fan a bit higher at idle. I'll probably still go up to the 300 Watt PSU because I know I am pushing this little 250 Watter too hard.
