Hi all,
I got a 9800pro in my rig but i would like to know if i get a 6600gtoc
from bgf, will i have to replace my psu it's a npires 450@430watts
--->
Nspire Power Supply NSP-450P4DL 450W ATX1.3 (12V/25A) 2 B.Bearing Fans
(1 LED) LED/Auto-Speed w/UL/CSA/FCC
And i'm concern on installing a 6600gtoc from bfg. My guess is that
this card is more power full than my 9800pro so it will need a better
psu.
i'm frustrated, i've try finding you a decent link for the voltage
but i couldn't. There is only the 12 volt rail that show 25 amps.
Also for those who got a nspire. Is yours come with a white kind of
paste between to capacitor. It visible from the rear" through the
fan"...?
thank you.
This article is for the PCI Express version. Basically it
draws all its power from 12V @ 4.35 amps. But the AGP version
also includes the HSI bridge chip, and judging by the heatsink,
that draws a few watts also, and wouldn't be included in the
Xbitlabs measurement here. Also, the powering circuits are not
exactly the same - it could be the AGP version splits consumption
differently. You can see the regulator circuits are different
in the two pictures of the video cards below.

6600gt AGP version, with AGP-PCIe bridge chip.

The 9800pro is here. 5V@6A 3.3V@5A
[email protected]. 53 watts in overclock.
The power split is entirely different than the other card (assuming,
of course, that the 6600GT AGP and PCI-e are the same, which they
are not).

There is a picture of your power supply here. The label looks to
be on the opposite side of the power supply case, so when the PSU
is installed, you cannot see it.

This page lists the numbers for nspire supplies. One other web site
rates the supply as "350W" ? Note that some other important ratings,
the combined power limits for combinations of outputs, is missing
from this table. That sometimes affects how much real 3.3V and 5V
you can get:

You could use this link, to work out a budget for the rest of
the components in your system. Since their video card list is
not up to date, work out the power, removing the video card
power, then compare the calculated currents on 3.3, 5, 12V,
to your power supply limits, and see if the "leftovers" are
enough to power a video card. I don't expect a problem, but
I'll let you do the math...

The white paste you are seeing, could be silicon rubber. Don't
go poking the caps, as there is a danger level of DC voltage
around there, and there is no need to take chances.
