Default Marginal OEM Power Supply

Maybe when you pay for installed upgrades, you pay for an upgraded power

it's easy to imagine that boxes might be shipped with upgrades such that
the power supply is often marginal or inadequate.

Anybody have any insight?

Except for gamer machines, vendors expect the cover to stay on.


Nonsense. Any PC must be expected to have memory and/or PCI cards
added.

Could you note the source of that opinion? Some where a major vendor said that?
For both cost and power efficiency reasons vendors seem to sell machines where
anything more than a memory upgrade puts it out of power. Add a disk, marginal,
hope you can power on spun down to avoid surge. And that 200w super gaming video
card? Not on the machines intended to let a casual user get on the net, or a
clerical worker do data entry or update a few things using the system as a terminal.

Seriously, I see stuff with 300w, even 250w power supplies, and as shipped they
have 50w of headroom if the voltage stays up. Honest, lots of vendorsmaking
them, and they work fine when used as intended.
