There is no such thing as PCI power supply. Case power supply can supply power to your PCI-E ports by means of 4, 6 and 8 pin connectors. It's especially true for new cards where PCI-E power is required to operate.
Anyway, there are couple ways to test pins. One of them is to buy computer power supply tester. Second is cheaper is you have multimeter... You can test each pair of pins, required voltage is standardized and can be found in internet.
Only if the motherboard has a PCI slot.
http://en.wikipedia.org/wiki/PCI_Express#PCI_Express_2.0 Yes it should. The PCI Express 2.0 is backwards compatible with the PCI x16 1.0 and 1.1 slot motherboards. However, PCI-e 2.0 cards on 1.1 and 1.0 motherboards will not be able to run at their max capacity.
Most are black, but they can be any color the manufacturer wishes to use. DFI motherboards often use colorful PCI and PCI-E slots.
yes ati radeon pci express' can go into Intel motherboards
You will have to open your computer and look inside your case. In 95% of motherboards, PCI slots will be white.
No, they are completely different. PCI is a general purpose card interface, AGP is specifically for video cards. Most often you will see an older machine that has one AGP slot and several PCI slots. Both PCI and AGP are out of date, you won't see any new motherboards or computers with AGP, and PCI is in 'legacy' status, that is, PCI slots are only included on motherboards to support older cards that the owner might have. The modern slot is PCI-e (which is incompatible with the older PCI)
if the pci express x16 is brocken and motherbord vga do not work what should i do
Most Pci-express x16 2.0 compatible motherboards
"What are the components of microcomputer ?
Phenom II X4 955 or PCI-E
Yep, that should be working fine. Just connect the 5770 to a PCI slot on the motherboard, and connect the power PCI power cable from the graphics card to the PSU (Power Supply Unit).
The main power connector 20-24pin. One for the CPU 4-8 pin. PCI express 4 pin. It's depend on what type of motherboard do you have. But commonly, new motherboards uses 2 power cord P8 and P9.
