Hi folks

I purchased my first shuttle about 4-5 weeks ago, sn25p, funky little thing. Unfortunately I had to RMA it because it would not power up with my 7900GT installed. So got a new one sent to me, changed the SATA cables, powered on, couple of times I had to switch PSU off and on again to get it on. Got everything installed AMD X2 3800+, 7900GT, 2gb RAM, 74GB raptor and a 250GB seagate, DVD-ROM.
All working hunky dory games were flying I was very pleased. Now it takes muchos switching on switching off PSU, disconecting cables and reconnecting them again and maybe if I am lucky the damn thing will boot.

Not much good to me like that, So i feel another RMA coming. However after 2 shuttles and a lot of stress and wasted time I feel like getting a refund and going back to a tower PC. My spec is no different to a lot of others with shuttles and a lot of people are happy.

Anyone care to convince me to soldier on with shuttle? Is it worth the hassle?

Cheers
 
have you tried it without the 7900?? i know shuttle psu's are damn high quality (ran my whole A64 rig on a stock 200watt psu a while ago without problems) but there grunt does have a limit, so maybe its that, thats causin it not to power up.

other than that, have you tried with one stick of ram, only 1 hard drive etc???

seein as this is your second shuttle, and you have the same problem id go with one of your components thats causing it
 
It is the graphics card that is causing it, unplug the power to the graphics card and it boots up fine.
I have a friend with exactly the same spec in his sn25p, and the graphics card works like a dream and doesn't have any power up problems.
Have tried with single stick ram, unplugging everything else except the graphics card but still get the same problem.

Also the PSU is the same one used in the sn26p which as we know is SLI capable.

Cheers

thats all well and good but not all components will be identical, some have better tollerances than others. my friends 200watt psu wont even boot with a 9800pro plugged in yet mine did happily and also with an x800pro.

also i think EVH had some power problems with his 26P in sli when he had one (im sure it was him that said it at least :))
 
I dont know the power requirements for a 7900 as apposed to my 7800 GT but my shuttle 25P hasnt had a problem powering up at all - and thats with sharing a lead with the dvd drive

I am brand new to shuttle's but I would be tempted to say "persevere"
 
shouldnt be the power supply. the sn25p uses the same psu as the sn26p which ive seen running two 7800GTXs which are a LOT more power hungry than a die shrunk 7900GT.
Defo check the sfftech forum - might be some funky compat error.
 
Thanks for the reply's much appreciated. I have indeed been on Sfftech.com, you may notice a near identical post on there under the user name 'ShootinJack'.
I have read through the above forums and taken on board all suggestions from previous posts. Still no such luck.

The shuttle will be sent back under RMA and hopefully will get a refend.
Have already ordered new mobo / psu / cooler.

Cheers

Are you sure they are the same psu..

I have seen a few posts that say that the sn25p psu has not got a 6pin pci-express power cable for the graphic cards...where the SLI sn26p psu has..
