I'm still considering the NEX 1500, and it's nice to see smaller variants coming.

It was more than missing screws, a 140mv spike is a big deal that is almost triple ATX spec, the temps are quite high and there was some build quality issues as well.

Hmm....now that's interesting. Thanks.

I stopped reading JohnnyGuru since the original guy is no longer doing it. But i'm sure this dude knows what he's talking about none the less.

They're not using Etasis in the sub-1kW units. If there are any problems with the lower-end NEX units they likely won't be the same kind of problems seen in the 1500.

750/650W are different OEM, different internals, etc.

Regarding the voltage spike on 1.5KW, we were unable to reproduce this, so we are not exactly sure why the result showed that way. Other reviews like this one from TechPowerUp, did not show it either.

These new guys are built by FSP, most likely based on the Aurum CM design, as you can tell by the EMI filter. 

 

The 750w Bronze unit is definitely based on the FSP Raider design, which isn't very good at all.

They also found some build quality issues and the performance of the unit according to both reviewers didn't match up with other units in the ~1500w class.

Negative spike... not nearly as big a deal as a positive one would be. ATX spec is 120mV... triple that would be 360mV. Never saw it get anywhere close to that bad.

I still don't think my two samples should be considered the norm for these units. I mean, look at the damage the second one showed up with. I have that second one powering my office rig now. If the anomaly's had any effect on stability, I have yet to see it. I don't expect it will.

Ah I thought ATX spec was 50 good to know.

I've read both Jonny and Okkies reviews. Okies reviews are a little more harder to please, I like that. And he thinks he is a comedian, I really like that. He Makes what would be another sleeper review light heart'd and funny.

At this point does it matter? No don't think so. Im not sure what the profit margin is on a PSU. If your going to have your logo on a piece of hardware that's going to be reviewed. Shouldn't you have gone thorough it with a fine tooth comb?
The very minimum plug it in make sure it works? I <3 EVGA staff/ people. Ive not had luck with EVGA's hardware quality, except their video cards.

Then again.... this leads to cherry picking review units to send out.
