7800GT & Low Wattage PSU

[ZXSpectrum]

A friend oof mine has got a Fujitsu Seimens Esprimo machine(AMD 64-3200) and he has just bought a 7800GTX for it. Now the PSU that comes with the machine is only a 240w one... He also has an extra large capacity S-ATA HDD in the machine as well as a DVD-RW...

He ran it all day yesterday with 3DMark05 and for a while with COD2 and it was fine... Will it cause problems? It says in the manual that it needs a 400w Minimum PSU...

Any help would be appreciated...

Could be that it is a good quality PSU, what even more important than the total watts is the Amps on the 12V rail, perhaps the PSU has a strong 12V rail and a slightly lower 3,3V and 5V rail?

If CoD and 3DMark run fine I guess it's fine.

You sure its not 240V and you're/he's reading the wrong bit? Surely no-one would use a 240W PSU with any kind of Athlon 64!

Not really that strange, most Shuttles also have low wattage PSU's

The Shuttle SFF's are different though. The Fujitsu is in a tower case (I think)? so it has a normal ATX PSU... I can't think of a high quality low wattage ATX PSU.

Yep its deffo a 260w PSU... Its kinda bespoke thingy with the PSU and CPU Fan and shroud all in one that comes out of the side of the case... Works pretty well...

So it isn't 240W?

I'd leave it, check the PSU doesn't get to hot as that could be a sign it's working to hard and getting ready to blow, which you definately don't want. Plenty of people run 7800's in shuttles and they are sub 300W for power.

if its a naff PU it could damage the system though if overloaded.

LOL... Its 240w with 260w peak... According to the sticker on the side... As far as i recall they are manufactured by coolermaster for FS...

Does it advertise the amps on the side? If the +12V line has 20A plus then you're fine

Did the PC come with any monitoring software? What are the voltage levels like in BIOS? If they're all within +/-5% and don't dip under load then it's fine
