Win7 late warning about graphics card power

[hdreck]

I replaced the graphics card in a PC. It is only used for e-mail, so I
went to spare parts cellar and grabbed what I thought was a low power card.
It had a PCIE6 power socket, but I did not notice then.
A week later, I got a warning from Windows to the effect that the
Nvidia graphics card does not have extra power, so performance has
been throttled, and I should connect the power or else the card might
damage.
Now I would expect that the first time I boot with this card that
Windows installs a driver for it, and the second time I boot then
such a warning should pop up. Why does it take half a dozen boots
before complaint arises???

Doesn't sound as if should/could monitor power consumption draws,
unless that's some pretty slick stuff your MB is providing some pretty
slick drivers.

Rather, that you're getting a generic message. Nvidia's, too. All
it's probably providing for is a warning for sensor logic at the plug,
that it isn't connected. Do your power supply math. Add up your total
component's consumption and figure it out. Are you now on the edge?
Like playing with fire? If not, maybe buy a plug/voltage
splitter/converter to stuff in it and shut it up.

Next time you'll have to watch for those PCI-E 6-pronged add-on plugs.

My bargain PCI-E card didn't have that, although I never used it. Just
sits around, an ASUS. I thought I might get something from it,
although I see no reason it would better the MB's chipped-video,
already. Looking at a extra hardware to kludge up a system build.
Only possible use might be a cooler situation than temperatures I'm
getting off the MB's native Nvidia chips.

Then, again, it's not that much trouble to cut up a spare heatsink,
mount it, and attempt to rectify whatever's driving one of my chipset
sensors up to 135F.
