The OEM of this PSU is Helly Technology, the mother company behind 1st Player. The platform’s PCB is small, and the design is clean, without cables blocking airflow. Despite the small PCB, there is enough clearance between parts to allow for easy and quick heat transfer. A large heatsink semi-surrounds the main transformer. Compared to other platforms, especially the ones by CWT, the heatsinks are large enough and high in number. As you can see in the first photos, this PCB is used for six variations of this model, from 850W up to 1300W.
Helly uses an APFC converter on the primary side, followed by a full bridge topology and an LLC resonant converter. On the secondary side, we find the typical stuff: a synchronous rectification scheme for 12V and a pair of DC-DC converters for the minor rails. The FETs that Helly used don’t belong to tier 1 manufacturers to keep the cost low, but this can affect the PSU’s reliability, especially at high operating temperatures for prolonged periods. On the other hand, the selection of electrolytic caps is good since products from reliable Japanese brands are used.
I wouldn’t say I like the fan selection since Yate Loon is low in my book of fan manufacturers’ reliability and performance. Globe Fan and Hong Hua are way better selections, which cost more. I am not sure if this fan to outlive the extended warranty under harsh conditions, despite the ball bearings it uses.
Based off Yate Loon’s nomenclature isn’t that model of fan ball bearing instead of FDB?
Let me double-check that.
What exactly does the red button next to the on off button do? Is it better pressed down or not?
It is for for the fan-stop operation. I would keep the fan constantly in operation.
Hey,
I was searching information about the Antec Neo Eco NE1000G M and looks like they use the OEM (Helly Technology). Antec even has a 1300W version too, like 1stplayer does, so it may be based in the same platform than this PSU, do you know if this information is true?
I bought the Antec one as i was in need of a compact PSU, plus got it pretty cheap (Less than 160USD). I was worried about the quality of the PSU as i couldn’t find any proper review of it, but reading this one and the price i paid, if the OEM is Helly Technology i think i made a good decision.
The Antec one uses a FDB fan tho, should i be worried for the fans as you said ”fluid dynamic is less tolerant to heat.” or about the FETs?
Thank you very much!
I am not sure if it uses the same platform as this one, because I don’t have close relations with Antec.
Helly proved to be a good OEM so far. FDB fans are ok for normal use.
Hi crmaris i can provide you with some photos for antec as i have it but i think it is build on the platinum build , i would be grateful if you you can help as i am a beginner in psu reviews :]
