How is this possible?

Hello all,



Can any PSU experts help figure this mystery out?



How is this possible?



This PSU:PCD010



Comes inside this machine: HP 500-319na



Before anyone asks why I'm not doing a self build - its only to be used as a HTPC, and i am getting it below the price, it would cost to purchase the parts separately (299).



I cannot work out how it is possible to run this spec on only 180W. Is there something fishy going on here? Is the machine being underpowered?



Does it look like the 12vb rail has been excluded from the wattage calculation?



To deepen the msystery - I then saw this: 3rd Party Lab - Load Analysis



I just can't work out the discrepancy. A 180W psu for an ATX system running an i5 - can't work out whats really going on.



Is there any chance i could add an MX100 (256 SSD) to this without changing the PSU?



My sincere thanks to anyone that's willing to contribute in solving this.
