1. Thank you for this fine article, the community has been screaming out for help deciding on PSU's (lack of knowledge on the subject as a whole) for some time.

Cheers.

2. Excelent article. I've never read such a well documented piece about PSUs.

3. Can you use the EPS12V (8-pin) cable, on say the Antec Neo HE 550 (550W) to power a Tyan K8WE (S2895) mainboard ?

I was under the impression that EPS12V compliance (not just for the 8-pin connector) required one pin to be different on the 24-pin mainboard power connector.

Of course you never stated if the Antec NeoHE 550 is EPS12V compliant (or that if isn't)*, just that it has (one of) the "standard" EPS12V power connectors (the 8-pin power one, usually for dual CPU socket boards).

* - Thus the question

Yes you can. EPS12V and ATX12V (ver. >= 2.0) connectors are the same.

"I was under the impression that EPS12V compliance (not just for the 8-pin connector) required one pin to be different on the 24-pin mainboard power connector"

Hmmm... which one? I can't see any difference between EPS12V 2.0 and ATX12V 2.0 (or newer). If you mean -5V (pin 20) which is not used in EPS12V, it's also not used in ATX12V since version 2.0.

4. Great article and very interesting.

The error safe pop-ups are very annoying though.

I apologize for the bad banners. The problem should be taken care of by now. Email me at anna@xbitlabs.com if the problem continues.

Much better, thank you Anna. :)

5. What a great, responsible, informative article this is, thank you Xbit and Oleg.
I’ll take more of this any day!
It is very sad to see so much misleading information in the computer industry especially by power supply and graphic card manufacturers.

6. Excellent article, complete and accurate unlike many other websites. You guys really know your stuff. I really enjoyed reading this. Now if only there was a 'Print' version I could download and keep for reference...

8. This might be a stupid question but is the CMPSU-520HX model tested/recomended or are u just assuming its a good choice? Also if Im not doing SLI is the 620 model worth looking at?
Thanks

9. Very impressie, detailed and informative article.

I wish all technical sites could write similar in quality articles such as this.

It is (together with hardwaresecrets and johnnyguru) the best site for PSU reviews.

Kepp up the good work guys! Inform us .. more! :)

10. Thanks for clarifying the mystery of the "dual rail" power supply. You confirmed that the concept is as unfathomable as it initially seemed.
