Corsair HX650 or Seasonic SS-650AM?

xaviiniesta6 · May 28, 2014

HX650 (80+ GOLD) is $10 more than the Seasonic SS-650AM (80+ Bronze) .
Is it even worth more and why?

From the review, the hx650 is manufactured by seasonic, because it is 80+ gold so it will be more expensive than the ss-650am (80+ bronze). And it is worth it.

Sorry, actually it is HX650 — 80 PLUS® Bronze? (not the 80PLUS GOLD version)

So is it worth?

The Corsair HX650 CMPSU-650HX is based on an older discontinued Seasonic group regulated design. It's not Intel Haswell Compatible.

What is the system configuration that this PSU is going to be powering?

FX6300 with 212 evo
M5A97 EVO R2
R9 280x Dual-x
2x4GB Hyper X 1600C9
Elite 431 plus

Will surely overclock the cpu and gpu.
Is it enough? I tried calculating wattage online and it says like 630w , so psu will have to work under load and all.

The Seasonic PSU is newer, so i'd chose that one. There are some other good 650W PSU's out there depending on budget, the Rosewill Capstone is very good for example.

I am not sure what method you use to calculate the power consumption, from what I did the system will only draw around 450W. So either one will be more than enough and because you don't use intel haswell so that there is not haswell compatible problem. Radeon R9-280X requires the PSU that has 30A on 12V rail and 550W.
And just get the ss-650AM.

I somewhere did heared that it requires 42amps on 12v rail with minimum of 600w.
Anyways thanks, i will do more research now.

Here is one of the review, the system ( i7 3960x @4.7ghz with same card) only draws 417W on load.

seen that, but many users using 550w psu did not be able to boot up, and succeeded after putting a 750w psu instead.
