6990 & 590

[LiuKangBakinPie]

Any one seen the recommended power supplies for these cards?

6990 ------->600w ---->1x6pin and 1x8pin
6990CF----->1000w---->2x6pin and 2x8 pin

GTX 590---->750W----->2x8pin
GTX 590SLI-->1200w--->4x8pin

Oh found a good reference chart for those looking to buy GPUs and dont know what amount of psu is recommended.

^Please take note that is the recommended ones which means it will be more than the avg PC power usage. But think about it at least you have headroom and you will have a better idea of what you need.

If your looking to browse PSUs

^Big Database. Click on the manufacturer and you will see the models nicely panned out with their connectors the works its all there. Plus If you look more to the right handside you will find links to reviews from all the creditable sites who normally give us the reviews eg Hardwaresecrets, HardOCp, JohnnyGuru etc etc.

:biggrin:

Do people actually use recommended power supply requirements? they are grossly exaggerated...

 

[LiuKangBakinPie]

yes some are but that is the best list I found so far. And if you look theyre not over the top than most.

Example like a 5750 4xCF they recommend like 620W. Plus the bonus of the connectors is there how many what uses

I don't spend enough time in the PSU forum, but isn't it better to use 65-75% of a more powerful unit, rather than 95% of a cheaper one?

I have an Epsilon 1010W that decided to stop working after two and a half years(I had it refurbished). I'm using q9450 at stock volts, Rampage Formula, 4gb Corsair and two 4870, therefore the PSU should be overkill.

Low W, high quality>Higher W, low quality.

agreed, a good 700 Watt PSU from a good company is a lot better then going 500 watts over what you need and getting a 1000 watt as cheap as you can. My 700 watt does the same job with the same components but it will last me 2 or 3 builds.

I agree with both ideals. Lower W quality unit > High W junk/cheap unit, but as Drivenbyvoltage suggested it is better to run a Quality unit @ 60-75% than one at 100%. More efficient, better temps, less noise, and overall less wear on the unit.
