Is +5V 2A enough to power this card or do i also need -5V to use it.

No clue specifically.. but I didn't check my PS before trying out the card, just put it in, and it worked. I have a 300 or 400 watt power supply with 4 hd's plugged in and a cd burner, on an athlon xp system.. so, dunno if that'll help. Confused

Thanks Tim.

My concern started when I read the FAQ that said:

"Is the card an universal pci card?
No, The card is a PCI 2.2 compliant 5-Volt card. Some new
mother boards may not support 5-volt cards."

along with the revision history of the atx12v spec that stated:

"1.2 Section 3.2.3.2 Remove -5V from all power distribution tables.
1.3 Remove guidance for -5V rail."

made me misteakenly concerned about -5v, then i read http://www.pcisig.com/specifications/conventional

"Conventional PCI Revision 2.3
Revision 2.3 is an evolutionary change to the PCI Local Bus Specification. Revision 2.3 makes a significant step in migrating the PCI bus from the original 5.0 volt signaling to a 3.3 volt signaling bus. Revision 2.3 supports the 5V and 3.3V keyed system board connectors (as did revision 2.2) but revision 2.3 supports only the 3.3V and Universal keyed add-in cards. The 5V keyed add-in card is not supported in revision 2.3. PCI 66, PCI-X, Mini PCI, and Low Profile PCI support only 3.3 volt signaling on 3.3V keyed system board connectors and 3.3V and Universal keyed add-in cards."

I think the FAQ was refering to that, I hope, dont know how I missed it the first time i looked there.

By the way, what im thinking of getting is a pci 2.2 motherboard (intel d875pbzlk).
