Gigabyte Greenmax Plus 450W
Gigabyte, mostly known for its motherboards and graphics cards, is participating in one of our power supply round-ups for the first time. Its Greenmax Plus 450W is a good fit for this budget-oriented comparison. Currently, only the company's 550 and 650 W Greenmax models are available in the U.S., but based on their pricing, we expect the 450 W version to show up in the $50 to $60 range.
Since this is not a high-end PSU, we aren't surprised by its fairly standard features. Its build quality seems OK, but not outstanding. The cables are non-modular and fully sleeved though, which is nice. The cable lengths and the number of connectors are average. There are but three Molex connectors and only one 6+2-pin auxiliary PCI Express connector. So, this power supply isn't really suitable for dual graphics cards, or even a gaming rig with one high-performance card (though that should have been pretty obvious in light of its maximum output). The 450 W PSU sports two +12 V output rails, each of which can deliver up to 25 A for a combined maximum of 32 A. No screws or Velcro bands are included.

Perhaps you should measure the inductance of your bulbs, rather than just stating they are purely resistive.
Thanks guys, nice article!
In the CX500. I think Samxon caps count as cost cutting.
On sale you can pick up the CX500 for $40 which is about as cheap as you will ever find any PSU. If you compare how well that Corsair backs its products, there really is no comparison - Corsair is the only choice.
As far as the Seasonic 360, why on earth would you buy a 360W PSU? I just don't see the point. While I can justify a 500W PSU to a budget builder, I really cannot comprehend recommending a 360W PSU to anyone. I feel cautious with a low wattage 500W PSU. All of these PSUs will run hot and loud if they are stressed and so moving up to a 650W or even an 850W PSU really is not that more expensive.
I got the gold rated 850W Corsair HX 850 for $144.00 on sale. I can not even begin to describe how excellent this PSU is. It runs as something around 92% efficiency under load and I have never hear the fan even come on (it may be that low fan is inaudible). It comes with a 7-year warranty and is modular.
If you are not strapped with a low budget, moving up is the only way to go. If you are, the CX 500 is a good choice.
PSUs run more efficiently under load. IMO, the trend has been to overkill on the PSU when it's not really needed. In reality, when you actually add up the max loads of all components a 350-450W PSU is more than enough to run most single GPU gaming builds.
