actually a athlon x4 with 6770 will only pull about 280 watts according to extreme outvision. Most builds should only have Antec EarthWatts 380D Green instead of 600-800 watt "monsters".

A highish end crossfire build only needs about 600 watts. The lower percentage of load your power supply is running at, the more heat is being produced, untill you get up to 80-90%. Therefore it is better to get a power supply that is approx.50-100watt greater than your need.


True about the athlon x4 and 6770 but if I say "get a 300W power supply" people will go get some horrible Chinese brand power supply that cant handle the system.

High end crossfire builds probably do only need 600W. But my example is with the GTX 580 which with an overclock can pull 600W in sli when using Furmark by themselves.

Why the "should only be rated for 380 W" for the Corsair CX430? It seems to do OK in the review. (Except that it misses 80+ requirements at 40 degrees by half a percent.)

second that. It is amazing what you get for the price though. In the states it costs $45 + a $20 rebate.

Because on the corsair site it says that the 12v rail only puts out 336W. If you compare that for example to the Earthwatts 380D all the power rating is from the 12v rail. So it feels a bit unethical to be showing the corsair as a 430W when it actually puts out less power than the Earthwatts. I think the Corsair is great for the price but the power is a bit misleading. I can change it if you want.

The EarthWatts 380D puts out 166 W on its other rails. But not at the same time as 384 W on the 12 V rails.

Ok yeah that puts out 336W on the 12v like the CX 430v2 so should i put the CX 430v2 in the "less than 400W" category or the "400W-499W" category?

Less than 400 W, as you have them categorised according to 12 V rating. Unless you change that, of course.

-12V and -5V
Not used anymore

1. Some HDD motors use +5 V, including all 2 1/4 inch drives. SATA drives also have +3.3 V, but I don't think any use it.

2. They also have +3.3 V, so can use that and doesn't have to use +12 V.

3. Modern RAM uses ~1.5-2 V and is adjustable, so is from a voltage regulator. Therefore, it will probably use at least +5 V, if not +12 V.

4. +/- 5% (according to Wikipedia)

5. +/- 50 mV (according to Wikipedia)

6. The CMOS battery is normally a CR2032 (you could mention it if you want), which is a 3 V lithium battery, which is generally non-rechargeable.

7. -5 V isn't supplied in modern PSUs, and is not part of the standard, so it is indeed not used any more. -12 V is probably not used either, but it is still part of the standard, and is present in all PSUs.

I'd suggest that you add a link to the 80 Plus website as well as other sites that help explain and scrutinise the 80 Plus standard for added transparency. Corsair and Thermaltake sometimes actually give their PSUs a lower efficiency rating than what Ecos Consulting certifies them as, something which I've seen people mark against Corsair and Thermaltake because of the "lower" rating. For example, the HX750 is given a gold rating by Ecos Consulting by Corsair decided to give it a silver rating. In reality, there are other gold rated PSUs which have similar efficiency to the HX750.

I'd suggest that for the list of recommended PSUs, you stick in the rating given by ecos consulting for those PSUs which were underrated by their sellers.

If people read reviews then a lot of the information given in this quick guide is unnecessary. Where do you draw the line? For a lot of people who aren't as informed a guide like this is invaluable and things like the efficiency rating can play a part in what they choose. It's a matter of increased transparency for buyers in a guide which is supposed to help them in decision making.

True. Even better than an 80+ rating then would be to list the efficiency at say 50% load.

The 380D is a lot noisier than the corsair vx, and the sound is not as smooth. I sleep with my computer a meter from my head, and it annoys me a lot that i have to turn my computer of every night, cause my current power supply is loud and does not make a smooth sound, and when i upgrade, i want that problem to be gone
