| 399787 | 2005-10-28 00:46:00 | is there a way to find out my current comp's psu watt rating? need to at least go above that.. notice how some of the cases i was looking at doesn't have 400w psu.. need to somehow find out my bare minimum |

| 399788 | 2005-10-28 02:18:00 | have you checked your BIOS? i think you can it there. Dominic |

| 399789 | 2005-10-28 02:44:00 | It won't be in the BIOS. The existing computer's PSU will have a label on it with the details. You may have to take a cover off to see it though. Just be aware that the existing PSU may be honestly labelled and the proposed brand could be optimistic. Some older designs have too much of the total wattage tied up in the +5 volt output that isn't used as much as the +12 volt now. | PaulD (232) | ||
| 399790 | 2005-10-28 04:08:00 | um..just that my damn psu don't have a sticker maybe it's under it or something..need to unscrew/unmount the whole thing to check.. |

| 399791 | 2005-10-28 04:33:00 | i got a mobile charger and compare that to other chargers it's like..weightless..doesn't feel metalish inside..well from the weight wonder what that's made out of.. Many mobile phone chargers now use "switchmode" technology which means they dont have a heavy 50 Hz transformer core. And I subscribe to the weight theory on computer PSU's as well. But I follow it up by opening them up and checking the build quality. The two factors seem to align very well. |

| 399792 | 2005-10-28 04:59:00 | um..switchmode..better look that up.. havn't heard of it before kk.. i'll be going to comp shops lifting psu to check weight i think i better not open them though.. |

| 399793 | 2005-10-28 05:32:00 | Instead of a heavy 230v to 6v transformer, they just use a diode to rectify the 230 volts to DC, then "switch" the DC on and off very fast through a very small transformer, the switching is controlled by the sensor that says "output volts is OK stop switching on and off" so its a well regulated supply. Exactly the same as a computer power supply. The higher the frequency, the physically smaller the transformer needs to be. I recently had to replace a PSU over a weekend, so bought a DSE branded one. It weighed 30% more than the same wattage rated rubbish one (Hyena) it was replacing and was very well built inside. Not expensive either, and a nice quiet fan. |

| 399795 | 2005-10-28 06:50:00 | I'm pleased to hear that as I'm getting one too. There was no indication who made it, even internally. Temperature controlled dual fans as well. The quality of assembly was first class, so much so that when I needed another one a bit later for another PC I repeated the exercise. Be interesting to know what makers label they normally have on them though. |
