| Just replaced the PSU in an old Compaq desktop PC, and this was attached to a 4-pin square power connector on the old PSU. There is some writing printed on the side; "OFT -F- (25ø)" (its cut off at the left before the "OFT" part). No other markings, and no means of connecting the other end to anything else. Any clues? PS: The PSU is a LiteOn 250W, model #PS-5251-08HP  |

| Dummy Load? |

| Might be. What's it do? |

| http://en.wikipedia.org/wiki/Dummy_load Not being sarcastic posting that url, it just explains it better than I ever could. Personally, I have never seen one on a computer PSU (at least not in the past three or four decades), but that doesn't mean a POS PSU may not require one for an unused connector to help regulate voltage for the motherboard. If you cut off the heat-shrink wrapping, it looks like you will definitely find a capacitor. I would be curious to see what else is under there ;) |

| I would be curious to see what else is under there ;) Me too, but I've already had three accidents involving stanley knives or electricity this year and I'd sooner not make it four.But yes, there's definitely a large-ish capacitor under there, on the right. The other long rectangular part has a wire poking out the other end, then folded back around itself. I'll stick the old PSU into my test PC in a few days time and test it out, since my original PSU has been 'borrowed'. Not bothered if it blows up, as long as it doesn't hurt. |

| It's clearly a can of beer on a CD coaster. (well, someone had to make the obvious gag) |
| ||
| Yes. That's my precious Carlsberg. :) |

| the lettering is just the spec for the heatshrink. the 25 means the diameter. I suspect it is a post manufacturing "re-design" hack job to accomodate the newer ATX 4 pin MB power connector. The long/roundy thing inside may be a ferrite and/or a cap to smooth the voltage for whatever reasons, or a fuse assembly. You are right though, it IS odd. I have not seen this before and i have had apart more PCs (XT,AT,ATX) than i can possibly count. :/ |

| thing inside may be a ferrite what would the RSPCA say to that? ;) |

| nah i work with a bloke who can channel richard whitley's spirit and a milder bernard manning at the same time ;) |
| ||
| LOL! Ahem, i mean the iron kind, not the furry kind... did i spell it wrongly? :D |
| ||
| nah you probably spelt it right, i just saw a visual pun and ran with it mind you i cant spell, thats one of the reasons i was kicked out of the magic circle (it took the idiot a year to get that joke) |
