4 out of 5 eggsWorks, but a bit noisy

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

Pros: Seems durable, the cables are extra-long so good for larger cases, plenty of connectors. 80 PLUS Gold rating which is 92% efficient.

Cons: The fan is louder than the rest of the machine.

Other Thoughts: I bought this so I could have a super-efficient PSU in my always-on ESXi game server.

5 out of 5 eggsAn exceptional 80+ Gold PSU for a good price.

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

Pros: - Inexpensive 80 Plus Gold PSU
- High quality constructions
- Sleeved cables
- Lots of SATA and molex connectors for connecting hard drives (NAS use)
- Big fan

Cons: - Lots, lots of cables, bad for cable management (although you should expect that from a non-modular PSU)
- No zip ties according to the pictures (that was just a joke)

Other Thoughts: I replaced my old power supply that came with my Dell XPS 8300. I plan to re-purpose it as a NAS later on, and this low wattage, 80+ Gold PSU is perfect for my needs, especially comes with 6 SATA connectors and 5 molex connectors to connect all my hard drives. The size of the PSU was relatively too big for my Dell case, my fault for that, should of check the size of the PSU before I buy it. Had to remove my front cover, top cover, GPU, and my optical drive, and the audio ports on the top cover in order to fit in my PSU. Other than that, it's a nice PSU. I have noticed a 10-20% lowered power consumption from my older PSU from Dell, from the result of the 80+ Gold rating. I can't tell what will happen to my PSU in the future, but for now, it's perfect.

3 out of 5 eggsNot that silent

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

Pros: Nice black speckled coating. Although may scratch your case.

Cons: The fan is not completely silent. It's too loud if you're looking for a completely silent power supply. I was under the impression this one would be silent since Super Flower (who makes this PSU) has high praise.

I ended up getting the Corsair RM650 (although it's $30-40 more) and at idle/low load it's completely silent.

5 out of 5 eggsWorth the money

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

Pros: Price vs performance. For low load systems this is an efficient, quiet and cost effective route to typical business or home, or theater computing.

Cons: Still plugs into the grid.

5 out of 5 eggsGreat PSU

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

Pros: I purchased this PSU to power up my home server. It is currently powering 4 hard drives and a DVD drives without any problem. I love that it has plenty of sata connections on it, plenty to power up all of my hard drives. I would buy this again! I also love that it runs quietly!

Cons: None at this time!

5 out of 5 eggsGreat little PSU

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

Pros: Relatively low cost GOLD certified psu when you catch it on sale. Has good power on the 12V and has no issue with it's intended use.

Cons: not module

Other Thoughts: While not a module PSU, everything was wrapped well and long enough cable to reach behind mb tray for clean wiring. Does what it's supposed to, quietly and efficiently. Wouldn't hesitate to buy it again!

5 out of 5 eggsI will be purchasing more Rosewill products.

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

Pros: -Quite performance
-Cables feel of good quality

Cons: -None to list

Other Thoughts: This is my first Rosewill product I've purchased for my own personal builds. I am very surprised at quality feel and performance of this power supply so far. Putting out enough power for a HTPC. All the cables have a good quality feel to them too.

5 out of 5 eggsGood for the price point

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

Pros: Plenty of connections
Quality construction
Cables are all protected

Cons: Lots of connections!!
Have to hide left over connections (nature of the price/model)

Other Thoughts: Nice power box for the price, very good construction and very quiet fan. Wires are all labeled nicely and has plenty of connections. The cables are also sleeved and heat shrunk for a nice clean look. Only disadvantage is not having it modular so you wind up with a lot of extra wire to clean up. But, you do know what you're getting and I'd use this again.

5 out of 5 eggs

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

Pros: Inexpensive 80+ Gold rated PSU

Cons: Not modular, but for the price I'm not complaining

Other Thoughts: This series is highly rated in reviews by people who know more about power supplies than I do. Seems to be good and stable in my system as well, so the only possible complaint would be that it's not modular. But I'd rather have the 80+ Gold (this system runs 24/7) than modular, and at this price I don't think you can get both. It even came with thumb screws for mounting in the case (I'm pretty sure they came with this and not the case...). I also like the textured finish, not that I'll see it once I put the side panel on. :-)

5 out of 5 eggsGood PSU for the money

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

Pros: This was gold certified and had Active PFC along with a great warranty. HUGE pros, hence the reasoning for purchasing. Excellent for a basic rebuild for my mother to replace her aged Windows XP machine.

Cons: Not modular, however I knew that going in. You get what you pay for.
