N/A 5/7/2013 2:40:20 PM Tech Level: 4/5 Ownership: 4/5 Verified Owner	Rating: 5/5worth it! for mild gaming system Pros: The platinum cert on this PS lives up to it. runs silent and cool (little heat on hot days). gotta go modular for less mess. the extensive safety built in features for power outage, surge, etc is a must have to protect ur system. currently running 2x4 gb gskillz (1800Mhz), visontek 120gb ssd, old sata 160 hdd, old video card radeon ati 4650 hd, fx6300 @3.5Ghz, on asus m5a99fx pro r2.0 Cons: it wasn't free... Other Thoughts: go with a 650+watt ps of the same model if u want to do high end dual video cards for safety's sake. Did you find this review helpful? Thanks for the valuable feedback you provided!
N/A 3/6/2013 3:26:32 AM Tech Level: 4/5 Ownership: 3/5 Verified Owner	Rating: 5/5Excellent Pros: Very stable, great warranty, modular cabling, silent fan, and never heats up. I've had some pretty bad luck with power supplies in the past, so for my new build I really wanted something I could depend on. So far I am really loving this thing. Cons: Expensive Other Thoughts: I got this in a combo deal with a free 1 tb hard drive, so it really made it a more justifiable purchase. Did you find this review helpful? Thanks for the valuable feedback you provided!

Cons: None really Other Thoughts: I had a hard time getting it to work at first I thought it was DOA but I put a paper clip on the black and the green wire and plugged it in for about 5 minutes and then it worked 1 out of 2 people found this review helpful.

Billy Joe Jim Bob 12/15/2012 9:03:00 AM Tech Level: 3/5 Ownership: 2/5 Verified Owner	Rating: 5/5Tachyon 550W Pros: High efficiency Modular cables Long length cables A good selection and quantity of connectors for future expansion Cable sheaths Came with a half dozen nylon cable ties - a nice touch. Came with thumbscrews and regular screws. Cons: None so far. Other Thoughts: The biggest reason I purchased this power supply was for it's platinum efficiency rating. I live down south where we use the air conditioning 10 months a year, so added heat load in the house costs you twice - pay to generate the heat and pay to pump it out. My old supply was a cheap one and it always had hot air coming out which heated up the room and caused me to run the ceiling fan. The air coming out of this power supply feels cold even after an hour of usage. The price was very good too relative to the other comparable power supplies. Hopefully Rosewill is a company who honors the mail in rebates. I really hate companies who stiff you on them. The cables were about 10 inches longer than the cheap power supply that I had been using. It was a nice touch to get the nylon cable ties, but when I was using them, I thought that I would have traded them for two reusable Velcro ties if I had a choice. I'm sure Velcro ones cost more, but a lost opportunity to get some free advertising by putting their name on the Velcro ties. The 5 year warranty is good, but the Fortress supplies have 7 years? I used the thumbscrews instead of the regular Phillips screws - it's nice to not have to go get the tools out if you don't have to. Can't really comment on fan noise. Couldn't hear any noise at low speed and have not had it rev up to higher speed yet. 5 out of 6 people found this review helpful. Did you? Thanks for the valuable feedback you provided!
