| 210053 | 2004-01-26 05:19:00 | Hi guys, System Specs: Asus P4P8X Mobo Celeron 2.4Ghz (over-clocked @ 2.65Ghz) 1GB DDR400 SD RAM 80GB HDD Asus GeForce FX 5200 (with its own cooling fan) 1 x tri colour 60mm case fan 1 x blue 60mm case fan I just installed Asus PC Probe and after having a look at all the various tabs available it appears that my +12V is over it's set threshold and is currently running at +15.503V. Am I correct in assuming that there could possibly be a fault with one of the +12V power conectors on my PSU. I used to have an orange EL-wire on my cases perspex window but one day it just stopped working, I don't know why, could this high voltage be the problem? Is it advisable to get a new PSU. I was thinking maybe a 400W or 500W PSU? Any idea would be great, I would rather buy a new PSU than tinker around checking the voltages with a multi-meter really. cheers chiefnz |

| 210054 | 2004-01-26 05:27:00 | what brand of PSU is it? sounds like u've got a cheap and nasty PSU with a 12v rail that high. | Pete O'Neil (250) | ||
| 210055 | 2004-01-26 06:01:00 | Hi Pete, there was a Hyena 300W P4 ATX PSU in the case i've nw replaced it with the cases original iCute 320W ATX PSU. Asus PC Probe still reports exactly the same figure +15.503V? Maybe I have too many case fans going I have the 2 case fans that I installed myself and the side perspex panel also has a fan too. Could there be something wrong with my Mobo? cheers chiefnz |

| 210056 | 2004-01-26 06:02:00 | Measure your PSU voltages first with a multimeter before you jump to conclusions. On-board monitors are not very accurate in some cases. | godfather (25) | ||
| 210057 | 2004-01-26 06:11:00 | I'll second that GF. The motherboard monitors are not designed as high tolerance measureing devices like a multimeter. Also, if you read carefully on the Hyena PS, you will notice that the power rating is for the input wattage. Normally it is figured on the Output wattage. All conversions have losses, so it is over rated between 10 - 25% depending on the design and load. Stick with the icute. |

| 210058 | 2004-01-26 06:16:00 | If a different supply has its 12V reported at the same voltage -- to the millivolt -- I would say there is something wrong with the measuring circuit. :D | Graham L (2) | ||
| 210059 | 2004-01-26 07:29:00 | not too many case fans and I dont know why you would bother replacing the 300w psu........people seem to think they need mega wattages to run everythign but you dont my system p4 2.4c Ghz 512 DDR dual channel......asus GeForce Fx 5200......cd writer .......one hdd........floppy.......modem etc running 300watt psu perfectly well indeed.......I haev the 'standard' p4 heatsink and fan and two case fans about the same size as the cpu fan and one small fan on the vid card............hell I dont need more power....... |

| 210060 | 2004-01-26 07:43:00 | drcspy, Why have you got so many fans?? With a P4 I don't see why ypou should need them. Possibly the one on the graphics but the others are meaningless. I have a P4 3.0 with 1024 megs of DDR 400 ram in a gigabyte board GA 8IPE 1000. I have a standard cpu fan and the psu fan. The highest temp. I have seen is 37 degrees at the cpu on a very hot afternoon. I also have a 300 w psu and don't see any reason for changing it. Jack |

| 210061 | 2004-01-26 07:56:00 | oh hell i'm just fussy lol ............well also the puter is a full atx case and there aint much room in the hole in my puter desk around it .......at the back of the puter there is a hole for the leads about 65cm in diameter and another one sorta above and behind the case.....theres about an inch of space on each side of the case between the case and the 'hole' in the desk and about four inches behind the puter........not much airflow..... as for temps well right now 8.30pm CPU 28c ...........MOBO 33c........and the most I've ever had it up to was when I'd overclocked it to 3.0ghz, (and it ran FINE....... )......then ran a sisoftsandra burn in test........well it got to 48 on the CPU....... |

| 210062 | 2004-01-26 08:42:00 | hmmm. yea - measure it with a multimeter (if possible) or try a new PSU. u can never have too many case fans (unless theres so many holes ur soundcard falls out of one). i have 5 (Hehe), plus a volcano 9 and my +12 rail is always ~12.2 volts. have 1 HD, 3 CDroms and 2 Floppy drives on a hyena 300w PSU. no problems. actually ill rephrase that. not many problems. (hehe). O well yea ur psu might be bung. | agent_24 (4330) | ||
