Lol, then 550W G-series for one GTX 670 or GTX 680 will be enough

Sure is. From the reviews though... Seasonic didn't over-spec the G-series as much as they did on the X and P series.

OK, and if you compare Seasonic G-series 650W vs Corsair HX650, which one is better?
Corsair offer longer warranty 7 years vs 5 years...

Please, need quick answer!!! Thanks.

If it's the older HX650 that's 80 plus bronze, that's an older Seasonic design, so the G series is better.

If it's the newer HX650 that's 80 plus gold, that's a Seasonic G series unit, so it's pretty much the same internally.

Because Corsair likes flipping people the bird used to have some kind of master plan, the HX650 models and other 650W units have only two PCIe power connectors, whereas Seasonic's G series 650W has four.

That said, with i5-3330 and a graphics card like you're mentioning, your build hardly calls for a 450W. I guess the lack of PCIe connectors won't even be an inconvenience at all for a single-GPU build. Why were you looking at 650W, anyway?

For better efficiency, maybe?
My old Enermax Noisetaker II 485W works for me almost 7 years in my many PC configurations, maybe I would like to buy something that suits me well in the future with some power reserve. I'm planning to have this PSU next 7 years also smile.gif
It's newer, todays HX650 with gold efficiency, so according to hardwaresecrets.com it's "Seasonic G-650 with completely different internal design".
What does it mean?

But when it's the same as you mentioned, then the 7 years warranty could be the benefit for Corsair HX650.
Only one bad point is only two PCIe power connectors, but I'm not planning SLI...

Which one do you prefer generally?
Thanks.

Didn't you misquote them?
Quote:
The 850W model is manufactured by CWT; however, the 650W model is manufactured by Seasonic, based on the G-650 model from this manufacturer. Therefore, they use a completely different internal design.
HX650 (gold) is same as Seasonic G, and both those are different than HX850 (new or old)

Just look at the pictures from the reviews:
http://www.hardwaresecrets.com/article/Corsair-HX650-Gold-Power-Supply-Review/1705/2
http://www.hardwaresecrets.com/article/Seasonic-G-550-Power-Supply-Review/1683/2
http://www.hardwaresecrets.com/article/Corsair-HX850W-Power-Supply-Review/741/2

Which two look the same in terms of layout and components?

650W would get you slightly lower efficiency (not anything that should be of any consideration) than 450W or 550W for the systems you'd use. The difference isn't worth anything, but if you use that as justification, then that means that you should pick the lower-wattage models.

HX650 has a different fan, but I don't know what the fan speed curve is like. If those were the same and the prices were the same, I would take the HX650 because of the longer warranty.

The only time you might yield better efficiency with a 650w than a 450w is if you are running your system under synthetics loads of Prime95 and Furmark/Kombuster; however, since your typical workload will be be around ~250w, you would yield better efficiency in that scenario, as well as in idle loads. Although, efficiency difference after 20% load isn't that much either way, so you are spending more on something that you don't necessary need.

BTW, there's a sale on some Rosewill PSUs ATM for 20% off. Particularly, the Capstone line. So if you are will to look at other options (unless you aren't from the NA), I would look at the Capstone 550-M for $72.

Yes, you're right they were comparing HX850 with HX650.
HX650 is just the same as G-650, my bad.
I will choose Corsair HX650 due to longer warranty.
Only I'm afraid if the fan isn't too noisy on HX650...

Rosewill is great, but I'm not from the States.
Btw. I can buy in my shop HX650 for just the same price as G-650, and 7 year warranty speaking clearly for Corsair, only the fan could be noisier, some people have problem
with it, what I was reading, maybe today's revision is better than half year back...

My budget is thinner now, so I must choose only from these two articles just now:

-Seasonic M12II 650W
http://seasonicusa.com/M12II-Bronze-650-750-850.htm

-Seasonic G 550W
http://seasonicusa.com/G-series-450-550-650.htm

They have practically the same price and same 5 year warranty.
My computer once more: i5-3330, going to buy GTX 770, 2x4GB RAM, 2x1.5TB Caviar Black, 2x12cm fan, DVD-RW, about 4 or 5 USB devices.
I probably never will use SLI.
I would like quiet PSU, not noisier than my GPU.

Please, recommend on of these two.

Thanks.
