      i purchased this unit (750-m capstone) after i read a few reviews from jonnyguru and techpowerup that reviewed this psu. they praised it highly and recommended it and finding out who its actually manufactured by it had me sold.

      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. it has an extremely strong 62amp single rail which allows it to the handle the most beefiest of video cards and highest of cpu overclocks.

      the overall presentation of the psu isn't anything fancy. is has a nice matte, black finish. with it being black it should blend in extremely well with most cases since black has been the latest fad for the last few years. it doesn't have any logos or graphics on the sides. even the fan doesn't have a logo in its center. only the bottom of the psu has the logo and basic information about the power supply which in most cases will be covered by the case. considering its a power supply what matters its how well it is at being a power supply not by how it lacks graphics plastered all over its self.

      the cables are of adequate length for any mid size and lower atx case. i personally have a cooler master haf xb evo and had no cable length issues what-so-ever. only cases that are full tower size and higher might face cable length issues with certain cables, mostly the pci-express ones. the cables themselves are sleeved in a nice mesh cover. the mesh is loose enough to allow for easy flexing of the cables but tight enough to protect and prevent pinching of the wires.

      don't let its affordable price cause you to have second thoughts. its cheap not because of its quality, but rather because its a rebranded oem. it's quality is superb and equivalent in what you will find in more expensive units. since rosewill out sources it to a oem they are able to sell them at a cheaper price and they pass the savings onto us. the oem saves money because they get a fixed number of units they have to produce, don't have to worry about producing to many, don't have the worry about the packaging, customer support, warranty, and distribution. rosewill saves money because they don't have to worry about manufacturing and research and development. other companies like corsair and evga do the same exact thing as rosewill, except they don't pass on the savings and charge the same premium as if you purchased it by the oem manufacturer themselves.

      coming over from a corsair ax850 to this I'm extremely impressed and pleased. I'm actually am more impressed with it than what I was with my corsair. it's is one of the best I have ever owned. I will definitely will look at rosewill again for my next psu purchase and highly recommend the capstone series to anyone looking for a rock solid psu.

      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.

      It works fine; it was well packaged, the instructions were clear and it is quiet.

      One feature that I liked was the fact that the cables are not "hard wired" into the power supply case. The product comes with a large selection of cables and there are jacks on the case. You just need to select the cables you need, plug one end into the power supply case, and the other end into the motherboard or device. With this feature, you don't need to deal with a lot of cables in the computer that are connected to nothing. There is even a zip-up case to store away the extra cables if you would ever need them in the future. Sweet.

      This review is for the Rosewill 80 Plus Gold Certified Power Supply ATX12V / EPS12V 650 Power Supply CAPSTONE-650-M

      Let me start by saying i had absolutely no idea rosewill even made power supplies, i’ve seen some cheapo cases by them and so i assumed the whole brand was kinda… cheapish and meh

      BOY was i wrong

      Not only was this power supply 75$CAD, making it the cheapest 80+Gold power supply i could find from a known manufacturer, but it extremely high quality for that price!

      The power supply itself arrives in a pretty standard and plain box, sporting the rosewill logo and not much else, but on the inside things get very nice.

      The power supply has its own custom foam insert to protect it during shipping, and the modular cables come neatly and individually wrapped inside of a little zipper bag, so you can store the cables in the bag if you aren’t using them.

      Installation was about as standard as possible, screw that in, plug that in, wow that was easy.

      The noise level is basically silent on this thing, which was nice.

      So far there have been 0 stability issues at all with this unit.

      A must buy, forget the mainstream brands that overcharge and underdeliver, i’m a rosewill fan now.
