-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 !!!
