Streetguru 5/2/2013 12:25:36 AM Tech Level: 4/5 Ownership: 3/5 Verified Owner	Rating: 5/5Perfection Pros: Has every connector you could ever want and is gold certified, also runs very quiet. Didn't instantly fry my board Cons: Not modular for the price, but can't really complain Did you find this review helpful? Thanks for the valuable feedback you provided!
N/A 3/19/2013 7:06:10 AM Tech Level: 5/5 Ownership: 3/5 Verified Owner	Rating: 5/5Nice PSU Pros: Nice PSU. Powder-coated black mottled finish is a nice touch. Long cords. Can reach from bottom of a full-tower case up to the CPU power plug near the top of the MB with length to spare. Gold certified means ~92% efficiency at 20% load. I've got a mix of eight 2.5" and 3.5" drives in a home server with i7-3770K (on board video) and at peak load it draws 120W (at boot) and idles at 60W. All cables are nicely sleeved. Cons: Wish they would begin innovating more flexible wires. The SATA power plugs have the wires going straight out of the back of the plug. That makes them a little stiff and hard to make for neat wiring. Other Thoughts: Rosewill is Newegg's house-brand. I've always had good experience with them. Did you find this review helpful?

N/A 2/6/2013 9:48:19 AM Tech Level: 4/5 Ownership: 4/5 Verified Owner	Rating: 5/5 Pros: Worked great on first use. Cons: None so far. Other Thoughts: There aren't a ton of connections on this if you're trying to hook up a system with a lot of peripherals, but I think that's to be expected from a 450w PS. It's also a bit difficult to stuff this into a MicroATX case, so a modular PS might be worthwhile in that scenario, but I managed to fit it into a SilverStone SST-PS07B.

specter 2/6/2013 6:23:25 AM Tech Level: 4/5 Ownership: 4/5 Verified Owner	Rating: 5/5power saver Pros: quiet lots of power lots of sata plugs Cons: none for this price Other Thoughts: used to upgrade some cheap psu i had. with killawat it was reading 37 watts in idle. with this power supply it went down to 22 watts under idle. running a asus e35m1 with 8 gig ram and 4 3tb hard drives for media server.

N/A 1/21/2013 10:21:02 AM Tech Level: 5/5 Ownership: 2/5 Verified Owner	Rating: 4/5Long cables Pros: Silent, efficient, good price, fancy packaging Cons: The main power connector is 20+4 with the 4 pin part unattached, so it's awkward. All the cables are too long. For example, the main power connector is 24in long. Compare that to the height of a full size case at 20in tall. Did you find this review helpful? Thanks for the valuable feedback you provided!
N/A 1/16/2013 9:28:57 AM Tech Level: 5/5 Ownership: 4/5 Verified Owner	Rating: 5/5Solid psu Pros: Most single gpu setups won't need more than 450w. 80+ gold is great, I wanted an efficient psu. 20/4 pin is helpful for different motherboards calling for different power. Two 6 pins boldly claiming "SLI ready" but I somehow doubt that. I've been noticing a lot of other products coming with these sorts of screws too -- but I like the easily removable type that don't necessarily need a screwdriver. This comes with the regular kind in addition to the aforementioned. Cons: Not modular, then again you aren't buying a modular psu. I have a GTS250 that I thought about using for physx in my 8x slot but there's no way I could power it with my GTX660. Comes with two 6 pins as I mentioned, I won't mark down because I didn't buy this intending to use it for sli/physx and I wouldn't personally recommend that you do. Other Thoughts: Rounds out to a solid psu for the price, so far more than enough power to run my new setup (I don't plan to do any ocing for a while because frankly nobody should need to): CM Storm Enforcer Rosewill Capstone 450w 80+ Gold MSI 970A G46 AMD 6x3.8 G.Skill 8gb DDR3 1833 EVGA GTX660 --which, as you can imagine, draws a lot of power. I've been hearing that Rosewill's been making quality products lately and I am definitely very impressed! Did you find this review helpful? Thanks for the valuable feedback you provided!
N/A 1/15/2013 8:44:12 AM Tech Level: 4/5 Ownership: 4/5 Verified Owner	Rating: 5/5Great PSU Pros: 80 PLUS GOLD Inexpensive High quality Cons: None Other Thoughts: I have 4 of these running 24x7 in servers. 2 of them for >3 months. Haven't had any issues whatsoever. Did you find this review helpful? Thanks for the valuable feedback you provided!
Helpfile 1/6/2013 5:41:30 PM Tech Level: 4/5 Ownership: 3/5 Verified Owner	Rating: 5/5Nice PSU! Pros: 80+ gold rating, 450W continuous, 140mm fan. Quiet & steady power so far! Cons: None. Other Thoughts: Way more power than what I need for my A85GX/A6-5400 system, but that'll change if I want to add a graphics card or two, or extra drives. Currently using about 200W of the power, so it should be pulling about 222W from the wall, as opposed to the 267W that a 75% efficient PSU would pull. Based on the cost savings, the PSU will have "paid for itself" in about 3-5 years and most likely have plenty of life left in it. Quite happy with the purchase! Did you find this review helpful?

Anthony 1/2/2013 12:12:26 PM Tech Level: 4/5 Ownership: 4/5	Rating: 4/5Unfortunately had to RMA Pros: Nice, solid construction Sleeved cables 5 YEAR WARRANTY 80 plus gold certified Plenty of connectors Cute carrying case on the box Cons: Had to RMA it. The power supply stopped working after about a month, and I wasn't even powering up much, just a low profile GPU and sandy bridge i3. Other Thoughts: I felt I should of got bumped up to the 550w series or even have the shipping costs covered, but still had to pay $20. I mean after all the product failure wasn't on my side. At least the process was quick and relatively hassle-free, the power supply is working now and I really hope I have no problems with it in the future. Rosewill products seem to be pretty good, I have the challenger case and I like it.

N/A 12/27/2012 7:48:56 PM Tech Level: 5/5 Ownership: 1/5 Verified Owner	Rating: 5/5Great :) Pros: Tested it out all seems well I shorted the green wire on the 20+4 pin cable Wich turned iron and everything seemed good I will review again after burn in and stress testing results Cons: Non Very quiet and very sturdy good craftsman sip Other Thoughts: Take a paper clip and short the green wire with any black ground wire and it should fire up Great way to test before installation 1 out of 2 people found this review helpful.
