each component in ya pc draws power from ya psu. can't remember what all the parts use (there was an artical in either pca or other pc mag) but i'm suprised ya pc is running with a 150watt psu. would suggest ya upgrade ya psu (your choice on what ya get 300 watt or 400 watt, personnal pref. would be 400 watt) before it blows, as it may damage any of the items in ya pc.

Many "brand-name" systems have PSUs rated lower than you might expect. You can rest assured that in these systems, the manufacturer has carefully tested that the PSU is sufficient for the system.

This just shows that "wattage" mania is not the be-all-and-end-all of PSU performance. The amount of power that a PSU puts out at each individual voltage, it's stability and performance under peak and transient loads are equally, if not more important.

If, however, your system has been assembled from standard components, it is inconceivable that a 150W PSU would be fitted, as they are virtually impossible to obtain. A Standard, good quality, 300W PSU would be ample for the components in your system.

I have a fast P4, two HDDs, DVD, CD-RW, 512Mb DDR-RAM, and a GeF4MX card, running very stable on a good quality 300W supply.

upgrade to a QTEC GOLD 550W , you can pick em up at most pc fairs for about 30 quid and they support pentium and amd.

Don't worry. If a "big-name" supplier underrated their PSUs, they would get hundreds of thousands going in the warranty period. They've got more sense than that.
