Pros: 150mm length, full modular, Seasonic G series based, eco mode, quiet , included so-called "PSU tester"

Cons: Warranty shorter than the inferior Supernova G1 , punched metal grille has higher restriction than wire grille , ripple suppression not top tier

Like the XFX XTR this is supposedly a tweaked Seasonic G series platform PSU. It is a slightly less capable unit than the Supernova G2 and G3 series but also tends to be cheaper , while also being shorter than the G2 series.

The PSU appears to supply around 12.096 to 12.168ish volts when I tried it , which means less than 2% deviation in voltage regulation. +5V rail seems to stay at 5.040 to 5.070V,+3.3V appears to stay at 3.344 to 3.364V.

Due to the included eco mode + full modular cabling that the Seasonic G series lacks , this provides small value-adds over that PSU. The eco mode switch would be on the inside of the case so that wasn't as well thought as it could have been, however.

As far as I can tell the fan is quiet, review sites state that it uses a Teflon nano bearing , which is marketing spiel. The eco mode allows it to run semi-fanless. Reviews have it ramping up the fan after ~ 50% load, so keeping below 300W load should be fine.

Likewise the 5 year warranty matches the Seasonic G series PSU line, albeit via a company which is one of the easiest to deal with as far as RMAs.

The only real concern is if you're looking for an absolute top tier PSU, in which case quite a few reviews have the +12V ripple to be around 30-40mV (which is not top tier but average) once you pass 50% load.

If you are thinking of buying this , compare the pricing with similar and better performing units. It won't be worth $90 but at $60-70 it is good value for good performance. Usually you see Seasonic G series units around $50 when on discount. It's certainly a better value than a semi-modular unit with GreatWall OEM internals (Corsair CSM), a bronze efficiency nonmodular or semi-modular, or Sirtec / Enhance build (many Cooler Master units).

If you're going to spend over $80 on a PSU I would likely recommend something like the Seasonic Focus Plus or the EVGA Supernova G3 series (which are based off the Superflower Leadex II).
