[SirenOfDarkness]

Hey i recently built a computer and i have my HD 2900xt

Thw 2900xt needs 2 pci-e power plugs in it to have enough power.

WRONG. It needs only 1 6-pin PCI-Express to be plugged but for maximum overclocking, the 8-Pin must be plugged. It's not 2 PCI-Express connector. It's 1 PCI-Express 6-pin + 1 8-pin connector.

But seriously, i have no clue why it didn't booted up at first time.

Oh and personally, i'd run the card with the 6-pin and 8-pin plugged in even if not overclocking. Just for safeness.

Sorry Patriote.....it does indeed need two PCI-E power connectors. There are however several configurations that you can have.

2x PCI-E 6-pin: Standard power input. No Overclocking through CCC
1x PCI-E 6-pin & 1x PCI-E 8-pin: Overclocking unlocked in CCC
2x PCI-E 6-pin + 2x Ground connectors (plugged into unused 2 pins on 8-pin female plug on card): Overclocking unlocked in CCC

My buddy tried booting his HD2900XT 1GB with only one PCI-E 6-pin and no dice.

Oh oh! Good info. I had heard the infos i posted above early in the release of the HD2900XT. So either 2 PCI-Express for non overclocking or 1 8-pin + 1 PCI-Express 6-pin for unlocked overclocking eh?

Correct.

[SirenOfDarkness]

i was aware of the 8 pin for overclocking it as well but i didnt think this thing would need 2 pcie 6 pins lol Cool alright were good then man this card is a hungry beast lol thanks for clearing it up they seriously need to specify this in the book in the box though where can i get the 8 pin connector for this thing? didnt come in the box so i assume that they dont have plans to release it just yet?

the 8 pin plug is the "new" PCI-e 8pin connector require by PCI-e 2.0 spec

now High enbd PSU provide both 6 and 8 pin pci-e conector since its gonna be more familiar with the new video card HD3k and gf9
