insuficent power with pciex16x slot

[stafiejulien]

I have a problem with HP DC 7700 SFF, the specs say that the 16x
pciex slot is assigned a maximum power of 25 W and so I could
install in the best case a Radeon HD 5450 which is in the limit of
25 W but is not a big difference from my current video card a hd 4350 .
My question is what happens if i install a video card with a
maximum consumption of 35 W because if you calculate the total
power remains quite enough for a better card.

my configuration
----------------
-power source 230 w (80 plus)

-processor > celeron e3400 ....65 w max

-memory > 4 gb 667 mhz ....20 w

-two hard drives ....20 w

-motherboard intelq965 chipset ....20 w

-no dvd writer (disconnected)

-----------
125 (+/- 10 w)

iff the power source can give say 200 w real power would still be enough

please someone help im quite desperate !!!

According to http://extreme.outervision.com/psucalculatorlite.jsp, your system needs around 140 W. You could use any card that will fit and will keep the total power under the limits.
