| 465823 | 2006-06-25 06:26:00 | Cant acutally say what the brand is... TUV Product Services...S/N 50968763. (if this helps) PC is P4 2.6 with HT, 1GB Ram, 128DDR Geforce card, 80GB HHD, DVD Writer... I reckon the psu is good enough for this.... nuthing much else on the pc.. |

| 465824 | 2006-06-25 07:44:00 | i don't think TUV is a brand . . . . mind you it wouldn't suprise me if it was ! what brand case? its proberly a cheapy but its fairly decent size so it should last ok . |

| 465825 | 2006-06-25 08:56:00 | 12.3v is fine, as long as it stays at 12.3v (or somewhere near it) if it was going all over the place all the time I would be suspicious | Agent_24 (57) | ||
| 465826 | 2006-06-25 09:06:00 | 12 . 3v is fine, as long as it stays at 12 . 3v (or somewhere near it) if it was going all over the place all the time I would be suspicious thats is just it . . . . . . . what do you call "somewhere near it" ?? i've had plenty of faulty PSU's that only show +/-0 . 5v . the only way to tell is to install a known good psu and compare the two . i normally find its not so much the volt difference or the drop in volts but the way it drops ie small but sudden drops for no reason and most important a change in sounds . edit: sorry to try and expain it better . . . . . just because it says its 12v dosn't mean its good . unforunatly its not as easy as just measing volts to determin if its good or bad . power factor and electical noise are also big factors exspecialy when caps have blown . |

| 465827 | 2006-06-25 09:49:00 | According to the official ATX PSU Specifications: 3.2. DC Output 3.2.1. DC Voltage Regulation The DC output voltages shall remain within the regulation ranges shown in Table 2 when measured at the load end of the output connectors under all line, load, and environmental conditions. The voltage regulation limits shall be maintained under continuous operation for any steady state temperature and operating conditions specified in Section 5. Table 2. DC Output Voltage Regulation Output Range Min. Nom. Max. Unit +12V1DC (1) ±5% +11.40 +12.00 +12.60 Volts +12V2DC (3) ±5% +11.40 +12.00 +12.60 Volts +5VDC ±5% +4.75 +5.00 +5.25 Volts +3.3VDC (2) ±5% +3.14 +3.30 +3.47 Volts -12VDC ±10% -10.80 -12.00 -13.20 Volts +5VSB ±5% +4.75 +5.00 +5.25 Volts (1) At +12 VDC peak loading, regulation at the +12 VDC output can go to ± 10%. (2) Voltage tolerance is required at main connector and S-ATA connector (if used). (3) Minimum voltage during peak is greater than 11.0 VDC However, like you say - this still does not determine if the PSU is faulty |
