PSU for 8800GT SLI

[pennyfan87]

Hi all.

I've currently got a Raidmax 530W PSU.

I also have a 8800GT, OCed to 660 on the core.

Will I be able to add in another 8800GT for SLI without a PSU upgrade?
If not, how many watts do I need on the new PSU?

(I'm running an E8400, with 2 HDDs, if that helps.)

I would seriosully think about moveing to at least a 650Watt it not a bit mroe i don't know about you but i like to do some upgrades besides GPU's 530 might be enough but later on with you want to ad in another say hard drive or a new CD/DVD/Blueray Drive you might not then have the power so i would go with a 650 or higher myself

Yeah that would really be pushing it. a good 650-700W would be optimal

I agree that power supply doesn't look up to the task. For one it doesn't specify max combined 12v.

I'm running a fairly loaded system (3.1GHz Q6600, two 8800GT, 2 optical, 2 HDD) on an Antec True Power trio 550W. But it has 41 amps on the 12v. I had the PSU and decided to try it, probably would have bought a 650W (8800gt SLI certified) model instead.

A Corsair 620HX would be more than enough.

The CORSAIR 650TX would be great as well, it has 52A on a single rail:

The PC Power & Cooling 610W is 49A on a single rail:

The Monkey is right the 620HX would work as well, it has (3) 18A rails, but is modular unlike the 650TX. So really it's preference. The TX is cheaper and I like PCP&C, they are just awesome it would be my choice at that price.

I have a pretty loaded system as well, OCed e6400 with 1.45v, 8800gt sli setup, liquid cooling, hdd/optical... and instead of buying a new PSU (the one I have is the BFG 650w sli psu) to be safe, I went and got the visiontek gpu/cpu dedicated psu that fits into a 5.25 drive bay. Besides looking cool, I NEVER have problems with it just running my GPUs. A lot of people report high exhaust temps blowing into the case, but I dont... as long as you have good ventilation you should be fine. Just an option, I mean, combined wattage Im sitting at about 1100, so my power setup will last me for quite a while without sacrificing money to buy a $300 monster psu.
