Need help with PSU

post #1 of 9
Thread Starter 
Ok so I have my current setup that's on my sig. I am going the route of crossfire but heres the problem. I have a Thermaltake V3 midtower case and the PSU is at the bottom rather than the top. I have a MSI 890 so its a fairly big mobo. I have been threw about 2 PSU due to the problem one of the power connectors at the top left corner that plugs into the mobo, the connector is not long enough for most of these PSUs. How I have it plugged in right now is that it pulls really tight covering my other PCIe slots.

So my question is can OC suggest me somes 750W+ PSUs that can overcome this problem

Oh yea I'm planning on Crossfiring 6950s if that helps

I would like to tuck all my wires if possible.

Sometimes I think I'm crippling my CPU with buying cheaper parts =/ like I went cheap on my HDD and my PSUs so far

The XFXs are probably the best price / performance ratio at the moment from what I've seen, but if performance matters to you, those seasonics are a steal (most quality PSUs are a rebranded / modified seasonic).

On another note, are you crossfiring 6950s, or 6950s you plan to unlock to 6970s? I might point out that you don't necessarily need a 750W PSU. A 650W would do you just fine and save you a few bucks here and there.

Antec TruePower New 650W is just what you want for Crossfire HD 6950s with a 1100T. It's on newegg now for $80 shipped:
http://www.newegg.com/Product/Produc...82E16817371021

Most non-cheapo power supplies should have the CPU power connector long enough for a typical midtower ATX case with PSU mount on bottom. It's mostly just with full towers and cheapo brands that you need to worry about that not reaching. It depends on the plug position on the motherboard too, obviously...but I think you can read reviews and figure out the cable lengths and measure the distance in the case yourself. If you need extensions, then buy them.

The 550W / 660W / 750W TPNs are the same design made by Seasonic and should be roughly the same except for a few components different here and there (in accordance to handling 550W, 650W, or 750W). There aren't a lot of reviews of the 650W version in particular, but a lot of 750Ws were sent out for review. As you can see, most reviewers were pretty impressed:
