XPG Pylon 550W Energy Provide Evaluate

The XPG Pylon 550W achieves decent efficiency for the factors of the class, regardless of having a fan pace profile that isn’t competitive. That stated, its reasonable noise output might be quieter with some adjustments within the design. For the internals, XPG used high quality portions for higher reliability along side an FDB fan, which is generally arduous to search out on this value vary. Designed to compete with the Highest PSUs for the ones on the cheap, the XPG Pylon 550W is in the similar marketplace phase because the Cooler Grasp MWE Bronze 550 and the Corsair CX550F RGB. 

Now we have already reviewed the equivalent, upper wattage XPG Pylon 650W, which carried out slightly smartly in our checks. This evaluate will take an in depth take a look at the decrease capability Pylon style with 550W max energy. All Pylon devices have 80 PLUS Bronze and Cybenetics Silver potency rankings and use a platform presented by means of Channel Smartly Era (CWT). There are not any modular cables as a way to stay the manufacturing value low.

The Pylon 550 has compact dimensions, with best 140mm intensity. In a singular however favored twist, XPG selected to equip it with a fluid dynamic bearing from Hong Hua, which is uncommon for this value class. FDB fanatics be offering top reliability and feature low output noise, however they’re costlier than rifle and sleeve bearing fanatics, so maximum manufacturers steer clear of them of their lower-end traces. 

However with this better-than-usual fan and its dependable CWT platform, XPG’s hopefully providing a 3 12 months guaranty. Thermaltake gives five-years in its Good BM2 line, which makes use of the similar CWT platform however does not have the section upgrades of the Pylon 550.

This XPG Pylon 550W makes use of the brand new CWT CSB-A platform, which spans from 450 to 750W, even if XPG’s aimed to incorporate a number of changes in this platform to extend efficiency and reliability. But even so the PSU’s Elite caps, which can be the most productive selection to Eastern caps, there could also be a high quality FDB fan by means of Hong Hua. That is a horny uncommon in finding in a Bronze PSU. 

The entire Pylon 550W’s heatsinks are small, and a couple of DC-DC converters control the minor rails. The 12V rail is passively rectified, despite the fact that, so potency does take a success. Alternatively, ripple is decrease as a result of SBRs aren’t as noisy as FETs.
