Any advice On PSU's?

[MrQ]

I need a good power supply for under a hundred dollars that can power two 8800GTS's in SLI.

I was looking at this one

But am kinda put off by the amount of DOA's in the comments section.

Gonna be honest, I don't like the price and the fact that there is no adjustable fan speed (which I am a big fan of). I'll take a gander around to see if I can find anything. What else do you have running in your rig? Is there a certain wattage you were looking for?

Thanks.

If you are not worried about price as much I would go with the PC Power & Cooling Silencer 750 Quad 750W or the 500W (which is much cheaper). I don't think you will need more than 500W. All "God Boxes" that I have seen don't require more than a 600W supply. According to your specifications I would even feel safe with 450W since even two 8800's will not draw more than 250W. I like silence in my cards which is why I would list the silencer's first. However...

The other PSU's I would recommend are the Corsair VX450 450W ATX12V 2.2 and the Seasonic S12 II series. They are both insanely excellent power supplies (I would give them silver stars and the cooling silencer a gold star) and are built with the future in mind (thanks arstechnica for that line btw). If you have any more questions just post again (I check these a few times a day).

<3 corsair

but i use OCZ gamerxstreme or whatever

haven't had any problems with it. not an overbearing Led on it either. Does support SLI.

I'm not sure you're going to find a "decent" PSU at $100 or less. You may think you're saving money, but a cheap PSU will take years away from your rig - and could cause problems in your software as well (random lockups, etc) that can be very frustrating to troubleshoot. As Frank Booth suggested, spend a little extra money and get a decent PSU at the beginning. It will be well worth the money in the long run.

[ ]Good

You can only choose two

That aside, I don't think you should ever go cheap on a PSU. I've gone cheap and it bit me in the ass. Be sure to get at least 100w over the minimum you'll need, as wattage in a PSU deteriorates over time, if you're a heavy PC user 100-150w extra will keep you going forever.

Based on the specs i would say it is ok, but watch out for maximum power rating. The continuous power rating is what you want to know. Companies just put the bigger number up. Still it is no Corsair, and there is a reason the Corsair is more expensive. Better capacitors, resistors, transformer, you can cut price by using cheaper components. Some have extra circuitry to cut down electric noise, so by paying more now you pay less in the long run.
