Can't see the PSU coping if it pulled enough power to trip the electricity, so my money would be a duff PSU. But I aint no expert.

OK, the basic story is that if I leave the 'leccy turned on all is well, however if I switch the PC off at the wall there's a 50% chance that it will trip the 'leccy when I turn the supply back on. I'm thinking either high initial power draw or faulty PSU, I'd rather it wasn't the latter since it's less than a year old. Any ideas? |

That's what I thought....stupid thing. I've got a 700W PSU powering a single gfx card and quad-cpu, it's not a cheap brand either so I'd be mightily peeved.

Would it not be under some kind of warranty or guarantee? Even if there's nothing saying that there is, a call to the supplier/manufacturer might be worth it... |

Oh it should be under 12 months warranty still, and even if it wasn't, I'd be breathing down the retailers neck with S.14 of the Sale of Goods Act ("lasts for a reasonable time"). I just don't want the hassle of sending it back etc and then having to "plumb-in" a new PSU. Plus that leaves me without my blessed PC for a while... |

Are you using the cable that came with the PSU with the right size fuse? |

I should be, though that's worth checking! I'll report back.

I'm no electrician but a couple of years ago we had a similar problem with our new shower tripping the main fuse box when switched on, or while on and even when turned off. From what I remember we had the apparently correct rated fuse in the fuse box and even changed it with a same rated spare fuse. In the end from what I recall was we upped the fuse from 40 to 45 amp - I can't remember exactly - but this fixed the problem. I'm not saying this is the solution but it may help. I do however caution you about having incorrect rated fuses fitted for obvious reasons. |

Well the plug for the PC has a 13A fuse in it, which seems correct? I have no way of telling if it's still the original cable - I have so many kettle leads lying about the place. It's done this in two houses now, so I don't think it's a problem with the wiring in the house (unless I just have really bad luck). |

The fuse in the plug should blow before the ring main does! Either that or your ring main has too small a capacity before it trips. If you are using a 4-way extension, I'd also rule that out as well. I've had one go funny before and blow the ring main. |

I *think* I might have solved it. I had re-wired my 4870 incorrectly after swapping-out a friend's card, it was drawing power from the wrong part of the PSU.
