Great power usage with little to no noise. Ideal for building a quite rig.

Got this for 60 which is an incredible deal for such a high quality piece of hardware. Riotoro are relatively unknown in the custom computer space but they use identical components to Seasonic which means this PSU is essential a Seasonic focus gold plus for 60. Extremely silent and even has a passive mode if you somehow are able to hear it.

My old PSU was beginning to sound like an airliner, this is as quiet as you can get them. More than enough power output for whats necessary in my setup.

working well at the moment and i like the looks and built quality is also good..the way how it works on paper is also very intresting ..

Purchased this as it is on the Tier 1 PSU charts, fully modular and 80+ Gold rating. Reading up, Riotoro, is a startup firm from ex Corsair & Nvidia employees. All in all well packaged and seems like a decent product however they need to work on their documentation as this falls down with badly translated instructions. Also on the back of the case it states "Hybid" instead of Hybrid and you can see this on the review models on the web as well so not just mine. This may seem like a niggle but it places doubt on quality control. Would I recommend yes I would as other than the slightest (none) issue the rest of the packaging and what is in the box is top drawer and backed up by a 10 year warranty (hopefully they're are around that long)
