5 out of 5 eggsSuperior PSU, as always...

This review is from: SeaSonic S12G S12G-650 650W ATX12V / EPS12V 80 PLUS GOLD Certified Active PFC Power Supply

Pros: Pros:

1. Extremely high quality
2. Value for the money
3. Extensively tested by review sites and giving great ratings
4. Seasonic name
5. Flat cables used on all leads except the primary ATX motherboard power cable which is sleeved. This makes cable routing FAR easier.
6. Came with cable ties, and Velcro cable wraps
7. Quiet...I cannot hear it even at full load
8. Seasonic case sticker...nice blue and silver one

I ALWAYS use Seasonic PSUs (or those brands that use Seasonic as their OEM). I have never had one fail on me.

The PSU was also very carefully packed in the box by Seasonic. Given how much foam it was encased in I am having trouble imaging how it could have possibly been damaged during shipping short of having the UPS truck drive over it...

Cons: None

Other Thoughts: My rig:

Core i7-4790 at default clock
MSI Z97M Gaming, BIOS v. 1.0
G.Skill 16 GB (2 x 8GB) DDR3-2133 at 11-13-13-31, 1.5V
Corsair H55 AIO water cooler
SanDisk Extreme II 480GB SSD
Seagate SSHD 1TB, 7200 RPM as mass storage
LG 24X DVD/RW
Steel Series Rival optical mouse
Thermaltake TtEsports Poseidon Z series keyboard
Dell 23" 2312 IPS display

5 out of 5 eggsSEASONIC S12G 650W

This review is from: SeaSonic S12G S12G-650 650W ATX12V / EPS12V 80 PLUS GOLD Certified Active PFC Power Supply

Pros: small, 650w of awesomeness, just what i need to power my rig without going overboard, bigger isn't always better, i'm not upgrading so no need for huge power, worked right out of the box no problem, plenty of cables plus cables are long enough to route through my HAF 932 full tower. I couldn't be happier with this buy.

Cons: Connectors are a little tight, but just wiggle them in carefully and don't apply too much force. Not modular, but i know what i was buying so it isn't a CON really if you know it's not modular.

Other Thoughts: powers my build listed for reference.

MSI Z87-G45 motherboard
MSI GEFORCE GTX 760 graphics
MUSHKIN STEALTH 8GB RAM
INTEL CORE I5-4670k LGA1150
1 optical drive

5 out of 5 eggsGreat fit with the Bitfenix Prodigy

This review is from: SeaSonic S12G S12G-650 650W ATX12V / EPS12V 80 PLUS GOLD Certified Active PFC Power Supply

Pros: I am quite happy with this PSU. I have been a fan of SeaSonic for a while as they make some of the best power supplies on the market, and even manufacture most of the components that end up in other manufacturer's high end PSU's. I value the PSU I put into a build very highly, as a low quality PSU can provide inconsistent voltage to components and shorten their lifespan. Also a poor quality power supply can catch fire/smoke.... I wish I could say I have not seen that happen.

I specifically got this model over others due to the 160mm length restrictions in the Bitfenix Prodigy case. I was a bit worried it would be hard to find a quality 600W+ PSU that would fit the bitfenix prodigy's 160mm length cap for the power supply bay. I was happy to find that this 140mm fits great! I did have to cut the zip tie that bundles up all the cables near the base of the PSU, but after doing that this psu fits great. It even left a nice bit of room on either side to stuff excess cables to reduce clutter.

Also, as most SeaSonic PSU's I have owned. This thing runs cool & quiet! Most of the time the fan does not even need to turn on :).

Cons: It isn't modular? Not really a con though as I knew that going into it. Also the price of this model is less than their modular ones.

5 out of 5 eggsTook a Shot, Not Disappointed. Impressive!

This review is from: SeaSonic S12G S12G-650 650W ATX12V / EPS12V 80 PLUS GOLD Certified Active PFC Power Supply

Pros: -Small compared to most power supplies (5.5 vs 6.3 inches in length)
-Fits my Bitfenix Phenom perfectly!!! Finding a psu that fit was hard!
-Black and flat cables, easy to route and not bad aesthetically
-Quiet fan, not top notch in looks or much else but works and I don't notice it
-Only ONE set of molex connectors! Finally someone realized no one used this connection anymore!
-80+ Gold, really efficient

Cons: -Non modular, some people may find this annoying and tough to route or hide extra cables.
-Simplistic, nothing specially or "poppy" for the eye to catch
-Motherboard 24 pin connector not flat and not entirely sleeved, end is colored

Other Thoughts: I found this PSU while looking for a perfect fit for my new Bitfenix Phenom case, which really can only house 5.5 inch long PSUs due to the restrictive cage underneath mobo, This fit and worked perfectly, and although I was initially worried about it working or being reliable because it is new in the market I was gladly pleased. Seasonic did not dissapoint on my first PSU from them, and by the way I had PSUs from Corsair and EVGA previously.
