If I were Gabriel I'd be concerned about the 11 volt drop in mains voltage between low load and full load. That seems like a lot.
Mine, while testing a largish PSU right at the theoretical limit for the copper from breaker to PSU, drops a whopping ~2v. The real limit is higher than the theoretical of course.

Beyond that I'm assuming the price was a major factor in the final rating, though Corsair's CX 750 bronze (which I assume is at least decent) is only five bucks more, and there's an FSP Raider (don't actually know if that's any good) $10 higher.

Raider is actually even worse than this one. Heck, my sample failed to do full power@12V.

CX750 OTOH is probably FAR better, as it has DC-DC regulation and therefore very different crossload profile.

My FSP Raider 550W seems to have probems with ripple&noise in general and voltage regulation with crossloads. The normal voltage regulation isn't great, but within specs.

I'm not too disappointed by the Teapo caps. I am surprised about the voltage drop, though.

Gabe says it's an excellent value for a 750W, but I can't find this thing for sale anywhere in the U.S.

EDIT: Looks like Amazon is about the only place, which makes sense for a company with no U.S. base. Warehouse your product at D&H for 2% and pay Amazon 8% commission for each sale and you're good to go!

It certainly isn't stellar value in PL either, if for the same price I can get Thermaltake Smart 750W or even XFX Core 750W, choice is not hard at all

Now it seems like everyone's Raider is screwed up. My RA450 has a V reg issue which push +5V beyond +5% limit under a rather normal load distribution. The ripple & noise on minor rails aren't good either.

I guess quite a few users have asked why their computer reported too high +5V voltage, and that's not a mistake this time.

As promised my Raider review. It's in German, of course, but you might find the figures anyway
