Thanks for the review!

I'm still very curious about the low end efficiency and wish there were a few more samples. I just want to know exactly where that drops off. Would it be drastic or more of a gradual curve between test 2 and test 3?

And has anyone seen numbers for the 120-140W DC area?

He's just asking for p-p ripple values in addition to the scope shots.

Well.. Review's done. I didn't record it. It's essentially a flat line and so within spec it's ridiculous, I'm not going to go into how the ripple is only 1.x mv when it's so low it's barely worth mentioning.

Thanks though.

Efficiency wasn't great for an LLC. Since 80Plus hadn't announced their Bronze to Gold certification at the time, it wasn't included in the design goal, I think. Also Andyson seemed to have troubles with ripples on VRM modules. Problems were related to layout probably.

Been keeping an eye on this, had a hunch a review would be up this week Thanks again for a great review, my expectations were sky-high and I admit to being a wee bit underwhelmed but that probably won't stop this bad boy from powering up my next rig.

Yup.... I simply wanted to see actual numbers so I had something concrete to compare to other PSUs, and to other other reviews of the AX850. Since individual units of the same make/model can have occasional variances (sometimes substantial variances), it would have been nice to see some actual numbers, but as the quote below so succinctly surmises:

I guess that says it all....

When you state there are other PSU's in this price rang that are better can you name a few?

Thanks for the review and all the good work.

Well the AX850 is hardly an upgrade from the Corsair HX850 and XFX Black Edition 850W, and those two sell for much less. Not necessarily better. This site reviewed both of them so you can read those reviews if you want.

Seems like it. Scroll down to the bottom of page 3. I would assume "hot load tests" uses a hot box.
