Enermax MODU87+ 700w PSU Review

Conclusion

Putting aside the fact that the blingy gold fan is about the most horrific thing I've ever seen on a PSU (OK, maybe aside from the entirely gold 'EG485P-SFMA24P' PSU that Enermax made back in 2004) , the Enermax MODU87+ 700w is actually one very good PSU. Over on the efficiency side of things the unit managed to maintain efficiency levels of around 90-92% through all of the standard tests and even surprisingly in the MAX load and +12v cross-load tests. Only in the +3.3v/+5v cross-load test did efficiency drop to 85%, but this is still the highest efficiency of any PSU I've tested when under these conditions.

Voltage stability was also more than acceptable too, with the unit sitting slap-bang on its ideals at a 50% load and only sagging slightly on the +3.3/5v rails under heavy loads. The +12v rail on the other hand was faultless no matter what I threw at it, and even when the PSU was subjected to a staggering 850w load, it still managed to put out a steady 12.00v!

The ripple results were yet another win for the unit, with the +5v rail impersonating someone who'd just gone into cardiac arrest, and +12v rail not really shifting at all from 50mV regardless of the load. Only the +3.3v rail seemed to show any signs of 'normality' by starting off at around 20mV and increasing to 30mV by the time the unit was running at 700W. Granted this result isn't particularly amazing, but it's still well within spec, so its hard to criticise.

As much as I'd like to comment on the noise output of the unit, due to insane din from the load testing equipment and about 10 other nearby devices all that have their own fans it's really quite hard to say anything that i'd be happy for silent PC enthusiasts to quote. However, unofficially (with my ear pressed to the fan grill) the MODU87+ appeared to be whisper silent all the way up to 700w.

Finally, the only thing that put a dampener on an otherwise pleasant experience was the 12-Pin modular connectors. On the unit we received at least, the cables were absolute murder to plug in. This was only made worse by the cringe-worthy crunching sound they made when they finally locked into place. Not an experience you'd want to have after spending out on a new PSU.

The Good
- Extremely high efficiency. Even in cross-load tests.
- Good voltage stability, especially on the +12v rail.
- Ripple results on +5v rail extremely good.
- Appears to run very quiet even under load.
- Stable at up to 850w continuous.

The Mediocre
- Ripple results on the +3.3v rail and +12v rails reasonably good.
- Some of the modular cables are combined Molex / SATA.

The Bad
- Gold fan is ugly as sin.
- 12-Pin modular connectors a right PITA to insert.

Best In Class

The battle for the best 80PLUS Gold certified PSU is already in full swing, so how does Enermax's contender fair?

Just been doing my weekly catch up of reviews and figured I'd give this a little read.

Top quality review as always Jimbo.

I never had any issue with the data in its table form myself, but for those that do, the graphs are layed out very well and extremely clear so you've hit the nail on the head there too.

As for the PSU... Hmm. Yeah it looks ummm odd shall we say but the efficiency is top notch.

Still don't think I'll be swapping out my HX750 anytime soon.

Oh yeah, and I'm not quite sure why this hasn't had any replies either :S.

I kept quiet cos that fan looks like it belongs in a Las Vegas hookers handbag! Results were very good though.

I dont think Ive ever seen an enermax that didnt have some kind of quirk in the styling though, the revolution for instance was ruined by the dodgy braiding.

Funny since they do a vegas range of fans http://www.enermax.co.uk/apollishvegas.html?L=2
