Which PSU to get? (Specific specs inside)

[nX07]

Hi there,

I am in need of a PSU for the new rig I am building.. the components of the machine will be very simmilar to this:

Q6600 CPU (Will overclock to about 3.0-3.2GHz)
OCZ Platinum XTC REV 2 ram, will overclock to about 2.2V (4x 1GB Modules)
Two DVD Drives
Two Hard-Drives

Will have an 8800GT GPU Most likely, but will upgrade in the future to a high-end card of next year generation. or SLi it with another 8800GT.

I want to future-proof myself (3 years or so), but I don't want to drop like $300 on a PSU.

Would a 650 Wattage PSU do that supports SLi, or do I need more wattage?

I second the Silencer, it's a great PSU and with the rebate and free shipping it's at a very good price.

Another vote for the Silencer.

You can also get this version:
http://www.newegg.com/Product/Product.aspx?Item=N82E16817341011&Tpk=Silencer+Crossfire
for the same price after shipping. The only difference is that this one has 6/8 PCI-E connectors, rather than fixed 6 pin. This allows it work with HD2900XT for example. It may help if next year's cards need 8 pin connectors.

Get yourself a good case. The Silencer is big, it won't fit in some small cases. Two 8800GT cards are very hot, so you need a big case with lots of fans. Look at the Silverstone TJ-09 for example, or Antec 900.

If I dont want to do SLi or Crossfire, would a 600W Cooler-Master Extreme Power Duo do the trick?

Cooler Master PSU's are low quality.

Get this one..... http://www.newegg.com/Product/Product.aspx?Item=N82E16817163066

((after a year of greed and self destructive behaviour - I have discovered that I am on Santa's bad list - so I am not even trying to be nice any more.))

Ok - stick with the PCP&C - but be warned....you will likely be stuck with it for a long time - and it will not provide the lovely fireworks, smoke and ambiance of the Powmax listed above.

If you never plan on SLI or Crossfire then this will do just fine http://www.newegg.com/Product/Product.aspx?Item=N82E16817703005
but if you might at some point want to use multiple graphics cards then go with the 750
