Enermax MODU87+ 700w PSU Review
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.
- 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.
- Ripple results on the +3.3v rail and +12v rails reasonably good.
- Some of the modular cables are combined Molex / SATA.
- Gold fan is ugly as sin.
- 12-Pin modular connectors a right PITA to insert.
Thanks to Enermax for sending the MODU87+ in for review. Discuss in our forums.
