I want to know that how much PSU power required for
3 SLI XFX 9800GTX+ 512 DDR3 card??
Means overall PSU wattage i want to know??????#!##!##!##!#
Motherboard : Intel 82945 GCCR(only one PCI 16x1 slot)
PSU : Solitier 500w.
First of all, your motherboard doesnt support SLI. It has only one PCIe x16 like you said. So forget SLI'ing.
Second, even if you were to run a low-level gpu you are advised to change your PSU asap. I highly doubt that it'll give 500 wattage. Avoid cheap psus as far as possible.
One more thing, instead of running GPUs in SLI/CF-X it'll be better to get a single powerful card. It'll consume considerably lesser energy, emit less heat and will save you space inside the chassis.
IS THIS CARD is VERY BAD for gaming......?
No.
Is this card is capable of playing recent games?
Yes.
btw, cut down on the excessive "???" -_-"
