I purchased a barebone computer that stopped working after about 5 hours. I traced the problem to the power supply witch is an Okia 450w power supply. This is the worst power supply I have ever came across Someone said this unknown brand is a little workhorse and is better than the brand name Well, looks like this horse is dead The case was getting hot within a half hour, it was warmer than the cpu heatsink I am using a 300w Award power supply now to power the same motherboard and the case is at room temperature. The Award power supply has stickers on it that says AMD RECOMENDED and PENTIOM 4 APPROVED while the Okia has none of those stickers. I would stay away from any power supply that claims to have 450w and does not have any stickers on it saying it's AMD or PENTIUM approved and that includes this Okia power supply
