Reported in BIOS or > monitor software may vary from actual. Thanks, I've tried measuring that using a multimeter. The 12v rail measures at about 12.6v, but the 5v line is only 4.9v. Is this likely to cause problems? The PSU is a brand new 450W Antec. The same PSU in a very similar system measures similar results. -- Cheers, Chris Howells -- howells@kde.org Web: http://www.kde.org.uk, PGP ID: 0x33795A2C KDE/Qt Developer: http://www.kde.org
