Hey, just upgraded some new parts and want to know what power supply I should get.

CPU: X2 3800 939
MOBO: ASRock 939SLI32-eSATA2 (http://www.newegg.com/Product/Product.asp?Item=N82E16813157087)
GPU: eVga 7900GS 256
RAM: 1GB TwinMOS DDR400
2 Optical drives
2 Hard drives
1 Sound card
1x120mm 1x80mm Case fans

First question:
The mobo I'm getting right now has a 20pin ATX connector, which is part of the reason I bought it because my PSU now (Enermax 350) only has 20 pin. Seems all new PSUs are 24 pin, so will this not fit? Will I need new mobo? Thinkin bout gettin new one anyway DFI NF4 SLI Infinity

Second question:
Here's the PSU I'm looking at
Antec TPII 550Watt SLI Certified PSU (http://www.newegg.com/Product/Product.asp?Item=N82E16817103931)

Looks like good rails, and its an Antec... Not looking to spend over 100 USD here. Want enough for SLI.


Thoughts? Alternatives?

Very good PSU i built a computer for my freind a week ago and I used that same PSU but his had 480watts. Its really quiet and is very nice quality.

Glad to see I picked the right one =)

What about the 24 pin connector, will it fit my 20pin mobo?

uh, no... He would have to get an adapter.

EDIT: The 4 pins break away from the 20 pin. So it can be either a 20 pin or a 24 pin.

r u sure dude

a12ctic is right. The 4 pins will hang over the side but it will work fine. You can get an adaptor for neatness, but as the pics show. The 4 pins can break away.
