Page 5 - Disassembly

We open this unit to find a sleeve bearing fan. EVGA is fortunate to have slapped a five year warranty on this unit, else that fan point would go away.

Yeah, that's a Super Flower Leadex variant if ever I saw one. And I've seen many.

No line filtering here, bub. Interesting to see the insulated push on connectors on the fan mode switch... usually, those get ditched first in cost-downing something to hit a certain price point. Soldering the wires works just as well.

This is a potentially good sign that longevity has likely not been compromised too much.

Soldering looks great on the mainboard.

There's your line filter. I count a TVS diode, four X caps, five Y caps, and two coils. Some after the bridge, which is a GBU1506.

The PFC parts are seen here... one diode and two 5R199Ps.

Normally, Super Flower uses shielding on their PFC control cards, but this unit sees that cost-downed out of here giving us a peek at the parts. There's an SF29603 and an SPN5003.

That'll be the PWM controller IC, there, an SF201T.

The minor rail VRMs use one NCP1587A controller and two AON6516 output parts.

Four of these AOT240L parts handle the 12V output. There's room for two more of them that are not installed.

All capacitors I've seen in this unit come from Nippon Chemi-Con.

Main switchers are found here, and are two more 5R199P parts.

Finally, the modular board. I haven't seen a thing I hate about this unit so far.
