Eggxpert Review
Pros: Modual as in my opinion every decent power supply should be, main 20+4pin atx power is sleeved and also modular. Quiet, very efficient, 62.5amps on 12v rail, arrived with 5x 6" zipties, required screws, ac cable, and a simple short installation folded page. -- No waste here, no badges, no stickers, no excess marketing material. The cables are long enough to reach all your components in most cases and to my surprise included a floppy power connector! 5 year warranty is always nice.
Cons: Only the primary ATX cable is sleeved, this is common for almost all power supplies and a fair disappointment. The cables will be too short to reach in larger cases and especially if you are the type who wants to tuck your cables away. Capacitors are of moderate quality, Teapo. 135mm fan is a non standard size which makes replacement should it fail more difficult.
Overall Review: While I'm somewhat impressed by this power supply I might make the small price jump to a premium brand. I installed this into a machine that is powered on 24 hours a day and draws a fairly steady 290w from the wall, we will see how long it holds up, it may surprise me but I fear with the capacitors it may not last long out of warranty. In fairness this is approximately 40k hours of use which far exceeds the average use hours in a 5 year period. Further note, Rosewill parts have continued to get better over the years, they've earned a respectable name in the industry.. I'm not sure who manufactures this unit but I've certainly seen far worse.
