SeaSonic G Series 550-Watt ATX12V/EPS12V SLI Ready CrossFire Ready 80 PLUS GOLD Certified Modular Active PFC Power Supply SSR-550RM - on Amazon.com
Question is: this one or one up for fully modular
I paid $80 for this drive and it's fine and I've never had a problem with a Seasonic drive. I have never had drive whine, nor anything else.
I think that $80 for this 550 watt unit is fine. However, this is a semi-modular unit, and I see the X-series, which is fully modular, on sale for little more than this series. Normally, fully modular makes no difference compared to semi-modular, since you use all of the fixed cables in a sem-modular anyway.
However, what I think s great about the fully modular is that if you need to swap it with a similar unit, you can just unplug all of the cables from the unit, slide it out and slide the other one in. The means no undoing and unrouting the motherboard power cables, etc. And that to me is worth something.
This isn't a criticism of this device, just something to think about.

Customer review : Silent, stable, efficient, and economical
This is a top-drawer power supply for a system with one powerful graphics card or two mid-range cards. It's efficient, silent at loads under 300W, and delivers clean performance at a reasonable price.
PERFORMANCE:
Fifteen years ago, most power supplies were about 70% efficient. For a 100W load, they would draw about 140W from the wall. Not anymore. We now have five major PSU ratings: 80 Plus and 80 Plus Bronze, Silver, Gold, and Platinum. These correspond to half-load efficiencies of 80%, 85%, 88%, 90%, and 92%. Efficiencies at 1/5 and 4/5 load are about 4% less than half-load.
This is an 80-Plus Gold unit capable of 90% efficiency. Relative to a Bronze unit, for a 24/7/365 system draw of 100W, you could expect to save about $6 a year in power costs at $0.12/kWH. Efficiency has other benefits: namely, every watt that isn't going the system is dissipated as heat. Less efficient units require a bigger or faster fan, which makes more noise...
