Provide good power and very quiet.
Cuong Truong
The modular cables made getting things wired up very nice and easy, as well as not having to find a place to stuff unnecessary cables.

If it lives a decent span, it will have been worth it.

For the rated efficiency level, this is the best deal for a power supply at this wattage and ideal for most systems. Fan noise knocks it down a star for my purposes.

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.

EFFICIENCY:

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.

WATTAGE:

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.

I bought this powerful 750 W gold rated power supply for my overclocked system. I've notice it runs cooler than my old Antec True Power 550 W unit.The 140 mm fan on this unit is very quiet and turns slowly even when heavily loaded. Everything is perfect on this unit except for one minor detail, then it has to do with the cabling for the graphics cards. It's fine for a single graphics card system utilizing both of the cables to hook up one powerful graphics card. But when you have two such cards, the weak link would be the sockets at the front of the power supply. Each cable for the graphics card has two separate six and eight pins plugs to connect the graphics card but on the other end that plugs into the power supply only has a single eight pin plug. On an extremely powerful graphics card that require two plugs for power, the plug on the other end may overheat and burn up. There are two such cables supplied. Lucky for me, I'm only intending to use only one such double extra power plug card in my system. This does not apply to the non-modular model. The semi-modular and in the non-modular model are identical electronic wise. The nonmodular one being cheaper to purchase.

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.

We were hesitated at first from reviews that said the fan in this unit is loud, and were about to go with a much more expensive $200+ unit. But after acquired it and installed and connected to the system and power up, its fan is VERY quiet. So if you are still not sure and worry about the fan's noise, don't worry anymore, go for this one and you will not be disappointed. One thing to mention, silly us (me helping my teen son), not sure which port to connect the cables to the SATA drives and the graphic card, because none of the ports in the back side of the unit were marked. We had to uninstall the unit then inspected each one of those ports and found they are all the same (having the same number of pins in all of them ports). After we were happy, reinstalled the unit and just plugged any cable to any port, they all power up and work fine. The mesh screen matched the HAF-X case making it looked very nicely!

Just installed this in a new build and no problems. Plenty of power to run the new system (i5-3570K, GeForce 660) and good price. The only minor complaint and not really a complaint, is that the SATA cables weren't quite long enough to allow me to use just one to connect the drives, so I had to use two. Other than just adding a slight bit of clutter to the build, it wasn't an issue. Overall, this is a great buy, and equal to the Corsair 750W I have in another build, but for less money.

For the rated efficiency level, the non-modular version of this PSU is the best deal for this wattage and ideal for most systems. Fan noise knocks it down a star for my purposes. Modularity is of modest benefit with so few unnecessary leads.
