- Good quality
- Modular
- High efficiency (80 PLUS Gold)
- None
I used to buy cheap power supplies, figuring that I was just going to replace them every time I upgraded my system. After reading reviews on a few different PSUs, I came across Seasonic. I found one on sale and after reading the reviews I decided to try one out. I started with a G-550 550w psu and have been very pleased with Seasonic ever since. I just replaced my 550w with this 650w of the same model, just to get a bit more power for a video card upgrade, but I really didn't need to. The video card recommended a 600w PSU but my Seasonic 550w 80 PLUS Gold unit powered the card perfectly fine, no issues. I just upgraded anyways, to be sure. Now I always recommend Seasonic to all my friends. Great value for the money.

80+ Gold
Top quality capacitors
Seasonic customer service and warranty!
None. It's still working great thus far.
80+ Gold is very efficient and outputs low heat. It's made by Seasonic so you know its built with quality parts and they really do make reliable PSU's and have great customer service and long warranties. something to always consider when buying a PSU as its one of the things that can fail most often.

Good Quality Cables
Quiet Operation
A few cables too short
Ticking/Clicking Noise
This is a rock solid modular PSU. The cables are good quality and snap in place without any issue on either end of the cable. The fan operates quietly and there is no noticeable coil whine to date (you can hear a little if you put your ear right up to it).
The only issue I have with this PSU is that a few of the cables are quite short and don't reach to the top of a mid-tower case.

Update: A few months in now and it has started to make a clicking/ticking noise.
