The 12 V single rail supplies up to 744 W or 62 A which mean it supplies practically the full power of this unit minus the standby power supply section which supplies 3 A of 5VSB or 15 W independently. The 3.3 V at 24 AMP, 5v at 24 AMP and the -12 V at half amp are generated by using DC to DC modules from the 12 V single rail.
I did a stress test on my system to see how much the voltage on this power supply fluctuates. When my computer is idling the voltage is as follow: the 12 V rail was at 12.192V, 5V rail was at 5.2V and the 3.3V was at 3.376V under benchmarking with my system fully overclocked, the 12 V rail dip to 12.080V with the others remains essentially the same.
Rosewill is Newegg's house brand. This unit is sold in other countries as the Super Flower Golden Green. It has a 140mm fan, a rough matte black finish, non-modular cables, and a single-rail design that allows for 37A at 12V. Jonny of JonnyGuru has thoroughly reviewed the Super Flower equivalent, along with the 750W version in the Rosewill line. Google his review for comments on soldering quality, components, and hot and cold efficiency tests.
The five general parameters for a PC power supply are efficiency, wattage, noise, size, and cable modularity.
Fifteen years ago, most power supplies were about 70% efficient. For a 100W load, they would draw about 140W from the wall. Not anymore. We now have five major PSU ratings: 80 Plus and 80 Plus Bronze, Silver, Gold, and Platinum. These correspond to half-load efficiencies of 80%, 85%, 88%, 90%, and 92%. Efficiencies at 1/5 and 4/5 load are about 4% less than half-load.
This is an 80-Plus Gold unit capable of 90% efficiency. Relative to a Bronze unit, for a 24/7/365 system draw of 100W, you could expect to save about $6 a year in power costs at $0.12/kWH. Efficiency has other benefits: namely, every watt that isn't going the system is dissipated as heat by the PSU. Less efficient units require a bigger or faster fan, which makes more noise.
This is a 450W unit. PSU fans generally run at idle speed until actual draw is about half the rated wattage. After that, the fan (and noise) ramps up. Optimal efficiency occurs at about half the rated capacity.Read more ›
don't let a house brand fool you. even though rosewill is newegg's brand, this unit is not produced by newegg. rather, like corsair, evga, antec, cooler master, and such, its outsourced to a third party oem. this particular unit, and the entire capstone series, both modular and non, is manufactured by superflower. superflower is a top tier power supply manufacturer that produces some of the best power supplies you can get. you will find many of their units housed in brands such as antec, evga, pc power and cooling ,and the like.
it has everything you would except in this day and age. its semi modular. meaning that everything except the cpu power cable and motherboard cable is modular. considering you have to connect the cpu and motherboard power cable, its extremely understandable why those are built in and not an issue.
for its cooling it uses a 1,200 rpm, 140mm, ball bearing adaptive fan manufactured by global fan. its speed is controlled by the temperature of the psu. the warmer it gets, the faster it moves. even at a heavy load the fan is very quiet, far more quiet the fans on my nh-d14 and gigabyte windforce 770. also since it's a ball bearing and not a sleeve this fan will last a long time even at high temperatures.
it uses all high quality japanese capacitors manufactured by nippon chemi-con. not poor quality chinese ones that like to either catch fire or blow up.
voltage, ripple, and stability is fantastic.Read more ›

I put this in a work computer; no performance issues, like all non-modular the cables are a mess but that is a fact of life for a cheaper PSU. Read morePublished 8 months ago by Smoked_Peasant
