5 out of 5 eggsGreat lower power quiet PSU

This review is from: Rosewill FORTRESS-450 450W Continuous @50°C, Intel Haswell Ready, 80 PLUS PLATINUM, ATX12V v2.31 & EPS12V v2.92, SLI/CrossFire Ready, Active PFC Power Supply

Pros: Needed a low power PSU for a server build. This is quiet, has enough power for the build and with high efficiency should make running the server as cheap as possible. Has all of the connections needed for any modern board.

Cons: None

Other Thoughts: Wouldn't do anything to intensive with it, great for what it can do.

4 out of 5 eggsAlmost Perfect

This review is from: Rosewill FORTRESS-450 450W Continuous @50°C, Intel Haswell Ready, 80 PLUS PLATINUM, ATX12V v2.31 & EPS12V v2.92, SLI/CrossFire Ready, Active PFC Power Supply

Pros: Very energy efficient, very quiet

Cons: Wrong power cable distribution, not modular cables

Other Thoughts: The choice of 4/6 molex/SATA power connectors is questionable, and 2/8 would have made much more sense, but pick up a couple power adapters and all is good.

This is in my media machine which is on 24/7 in the living room, and it runs nearly completely silent. This PS consumes about 100 W less than our old one, and 100 W x 24 hours x 365 days = 876 kWh per year, or nearly 8% of our electric bill, so it totally pays for itself by that alone.

5 out of 5 eggsGreat PSU

This review is from: Rosewill FORTRESS-450 450W Continuous @50°C, Intel Haswell Ready, 80 PLUS PLATINUM, ATX12V v2.31 & EPS12V v2.92, SLI/CrossFire Ready, Active PFC Power Supply

Pros: Runs quiet and not too hot, simple install and connectors all work fine with no problems. Really the best part is the lack of noise. The computer that this went into replaced one of the noisiest machines I have ever heard; so it was a very welcome relief to NOT hear anything.

Cons: None so far, hopefully it can handle a little dust!

Other Thoughts: Love having a higher efficiency unit, much less wasted heat, at least it seems that way.

Pros: Big, solid power supply.

Cons: cables very thick. not enough room behind hard drives to connect cables with computer case side panel on. Had to use sata extension power cables or move hard drives into the 5.25 bays in order to attach the cables. Not that big a deal.

5 out of 5 eggsGreat stuff

This review is from: Rosewill FORTRESS-450 450W Continuous @50°C, Intel Haswell Ready, 80 PLUS PLATINUM, ATX12V v2.31 & EPS12V v2.92, SLI/CrossFire Ready, Active PFC Power Supply

Pros: More powerful than you may think.

Cons: Not modular, but I knew that going in.

Other Thoughts: I'm always trying to making my gaming PC a little cooler, quieter, and now more power efficient. So, when I was looking for something to replace my old non-80 plus power supply, I thought I would do something crazy and try a 450w PSU for my gaming system. It works flawlessly.

Specs:
- OCZ Vertex 4 128GB x2 in RAID0
- Western Digital RE4 2TB
- Core i5-3570k, modestly OC'd to 4.2 Ghz
- Sapphire Radeon HD 7870 XT, OC'd to 1100 Mhz with voltage turned up 20%

I've stress-tested this machine with Furmark and long gaming sessions, and this PSU has not hiccuped once (knock on wood).

The down-side is that I'll never be able to cross-fire without buying a new PSU, but I've always been a single GPU guy.

5 out of 5 eggsNice, not greatness

This review is from: Rosewill FORTRESS-450 450W Continuous @50°C, Intel Haswell Ready, 80 PLUS PLATINUM, ATX12V v2.31 & EPS12V v2.92, SLI/CrossFire Ready, Active PFC Power Supply

Pros: Well constructed. Quiet. 7 year warranty is impressive. Single rail.

Cons: Only 4 watts more efficient at idle than a seasonic bronze [60 less]. Break even is 17 years [24x7x365] given 0.1$/kwh and is 10watts is 6.8 years. Point is I will stick to bronze rated units given the multi-year payback times. It is true I have not calculated the cooling costs for 3+ months of the year, nor when it does not matter nor the time waste heat helps heat the home.

Other Thoughts: Bought for a 24x7 server.

5 out of 5 eggsAwesome!

This review is from: Rosewill FORTRESS-450 450W Continuous @50°C, Intel Haswell Ready, 80 PLUS PLATINUM, ATX12V v2.31 & EPS12V v2.92, SLI/CrossFire Ready, Active PFC Power Supply

Pros: Very quiet, almost silent. Large 135mm fan does a great job moving alot of air at low rpm.
Got it on sale 69.99 which is great, it'd be even better if I endup getting the MIR with it as well.

Cons: None so far. Possibly when it comes to the MIR. Just hoping I actually get it back.

Other Thoughts: Awesome deal with shell shocker. I needed something quieter for my gf's build. Originally had a psu with two small loudish fans and I had an 80mm case fan going. I replaced the psu AND removed the small loud rattling case fan and now you can't hear any noise. The case mounts this on top so it does a better job with just this and no case fans! Makes me very happy.

5 out of 5 eggsGreat PCI wifi desktop card 4 $

This review is from: Rosewill FORTRESS-450 450W Continuous @50°C, Intel Haswell Ready, 80 PLUS PLATINUM, ATX12V v2.31 & EPS12V v2.92, SLI/CrossFire Ready, Active PFC Power Supply

Pros: Inexpensive, reliable, comes with mini form factor bracket just in case.

Cons: None.

Other Thoughts: Can't beat this card for the money, if you have an older desktop you need to retro fit to have wifi this is the card for you!

5 out of 5 eggsGhost PSU

This review is from: Rosewill FORTRESS-450 450W Continuous @50°C, Intel Haswell Ready, 80 PLUS PLATINUM, ATX12V v2.31 & EPS12V v2.92, SLI/CrossFire Ready, Active PFC Power Supply

Pros: I just built an "everyday" computer for a family member with this PSU. after about 5-6 hours so far this thing is quieter than the only 2 fans in the system (a 120mm NZXT fan and a 60mm AMD stock HS fan)! TWO other fans and I can't even hear this thing even hum. Honestly they should have called this the "Ghost" series.

Cons: Not modular, but you should expect that for a platinum ratinf

Other Thoughts: I will update this if I have any problems but for now its butter smooth
