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 !!!
A PCI express slot will deliver up to 75W of power. However, if the card need it's own power source directly from the power supply via 6/8-pin cables, it uses much less power from the slot (25-30W), and more from the power supply. PCIe's can deliver up to 75W, so you should have no problem installing this card which AMD specifies has a typical load of around 19W.
