I am looking for a 650W or more power supply that meets these requirements:

1. Has at least two 6pin PCI-E connections.
2. Has at least one 8pin PCI-E connection.
3. 8pin connection actually has 8pins and is not a 6+2 connection.
4. 6pin and 8pin PCI-E connector clips don't need to be "shaved" in order to fit into my 9800GX2.

5. The depth of the power supply cannot be larger than normal. My current power supply is an Antec TruePower Trio 650 and it has a depth of 5.5 inches (14cm). It's already tight in my Antec P180 case and any longer wouldn't fit.

Can somebody help me find a power supply that meets these requirements? I'm hoping for two 8pin PCI-E connectors if possible, but I need at least one. I don't know if anybody even has a power supply out now that has an actual 8pin PCI-E connector that isn't one of the 6+2 connectors. I really would like to stay away from that if possible.

Thanks for any help people can provide!
 
I have been looking at this toughpower http://thermaltakeusa.com/product/Power/ToughPower/W0172/w0172.asp#specification but it is 6.2 inches so I'm measuring tonight to see if that will fit.

The main reason I'm trying to stay away from the 6+2 connectors is that on a lot of the pics I've seen those just look very fragile and the 2 ground connectors coming from the 2 extra pins are fairly small. I've heard that these type of connectors are sometimes the cause for the latching clip not lining up with the case of the 9800GX2.
 
All I'm gonna say is, be very carefull if you shop at zipzoomfly.com A lot of their PSU's are listed as having an 8-pin pci-e plug and no 8 pin cpu plug when it's actually the 8 pin CPU plug and no 8-pin gpu plug. I noticed that on several of the PSU's listed by comparing zips stats to the stats on the manufacturers sites. But definitely check out zips prices though, they beat the egg on a lot of stuff. I buy from there but I look up the products I want elsewhere.

Maybe they forgot to include it, but on that corsair page they don't show that the power supplies have any 6pin connectors.

Scroll down to "Corsair TX Series Connectors:"

You don't see the 6+2 connectors there?

I did. You can't use those 6+2 pin connectors as 8pin connectors. Look at the clip on them. The clip needs to be centered on both 6 pin connectors and 8pin connectors. You lift up the two on the side and your clip is no longer centered.

I read on one forum someone saying that no corsair power supply is 9800GX2 compatible, which would make sense if that is the only way you can get a 6pin connector on a Corsair power supply.

Well it's nice to know that the blame goes to nVidia. I am still not going to buy a power supply that has a 6+2 connector. That's just as bad if not worse than an adapter to me.

With as nice and expensive as my system is, and that the power supply and it's cables are the one thing that can litterally kill everything in your system if it fails, I'm not taking that chance.

Surely power supply makers realize there are a lot of people just like me that are unwilling to purchase their power supply if it has a 6+2 connector on my end. I'm not going to connect some "jerry-rigged" connector to my ~$550 video card.

If I had found an adapter locally I would have ran that until a new power supply came in, but not more. Look at the wires that connect the 2pins to the 6 pins. They look very small and not bulky like the rest. Not on my system.

While it's nice to know that the 6+2pin connectors may not be a problem, it will give me piece of mind with a solid 8pin connector... and from the looks of it, the only trusted power supply manufacturer I've seen that has that is ThermalTake. While their PSUs are extremely overpriced, I find myself willing to fork over another $213 for a power supply on top of my recent video card purchase, just to ensure I have a system that isn't going to fail me or blow itself out.

(BTW the only power supply manufacturers I personally trust are Antec, Corsair, and ThermalTake. But neither Corsair or Antec offer PSUs with full 8pin connectors, they only offer that 6+2pin connector.)

Now it just comes down to waiting for a week for my new power supply to arrive, while my 9800GX2 sits for a week taunting me.

I already got screwed once by thinking that my 8pin mobo connector was the connector I needed. I'm not going to get screwed again and purchase a power supply where a 6+2pin connector is "suppose" to work, but doesn't fit. The only way to be certain is the full, 100% 8pin connector without any of this 6+2pin connector crap all the other manufacturers seem to think is OK.

That's one way to show your potential buyers that your power supplies aren't about quality.
 
Just got my new PC Power and Cooling 750w power supply to run my 9800gx2. Looks like it has a pair of 6+2 connectors, in addition to a couple 6 pins. The 8 pin connector is only for the mainboard. The 6+2 connector did not require any 'shaving' - just fit and was solid.

Man that video card cranks out heat. I was shocked... As hot, if not hotter than my raptor!
 
Gutspiller, I'm a little confused. What makes you think that a 6+2 configuration is going to kill your system? If a PSU kills your system, it wouldn't be because of that, it would because it was a crappy PSU. I've read the stories about the 6+2 latch not lining up with the latch on the card, but there are workarounds, none that I think would inherently kill a system. If you want to go with a native 8 pin connector for aesthetic reasons that fine, but saying that a Corsair or other quality unit with a 6+2 connector is going to kill your system is just wrong.
 
Hi, I was also looking for a PSU that had an 8pin connector that would fit my 9800GX2 without having to shave some off. I ended up buying an Ultra X3 1000watt PSU because they advertised that the PSU meets ATX 12V Version 2.2 Specifications. They were right. It came with an 8pin connector, not the 6+2 connector and it fit perfectly without me having to do anything. It also comes with two 6pin connectors. The only problem I see is that it is 7 1/2 inches long. So far it is the only PSU that I have seen that gets it right. There are probably other PSUs out there that have the same number and type of connectors, but I don't know of any. I'm not a big Ultra PSU fan, but this particular PSU got an excellent review form Jonny Guru and it is only $199.00 at directron.com. I took a chance and have been very happy with it.

Here is a link to the review and the merchant. Good luck.
