Power supply advice

Faultline · 09-12-2007, 07:35 PM

I've been thinking of purchasing a new rig in the next few months but I don't know how big of a power supply I would need.

The system specs I'm toying with are:

CPU: Intel Core 2 Duo E6750
GPU: 2 Nvidia 8800 GTS running in SLI
Memory: 2 Gb DDR2
Hard Drive: Single Western Digital Raptor 10K
Optical: Single DVD drive

Haven't found a good reference out there anywhere. I'm thinking somewhere in the neighborhood of 850W. Anyone got any tips or ideas?

You don't need 850W; you can run that system off much less. I highly recommend this power supply. It is the highest rated power supply I have ever seen anywhere (not just talking about on new egg). It has 2 x PCI-Express outputs too for your 2x 8800 GTS.

How would I know though? Does each component come with an estimated amount of watts required?

It's hard to really say how many watts are enough. I'm using a 500W with a single 7900GT, 2 harddrives, 4 case fans, and 2 optical drives.

Check slizone.com for estimated requirements on 2x8800GTS. That'll give you an idea for the base requirement. You may want to add 100W to it for growth. Although, there's not much room to grow when you already have 2x8800GTS unless you replace it with a higher end SLI setup.

A quality PSU with around 600W output should be more than enough to handle your rig. You might be able to pull it off with a 500W one as well, but a 600W would put you in the safe zone.
