Seasonic vs. Corsair - Page 6

post #51 of 75
If you compare Seasonic G-series 650W vs Corsair HX650, which one is better?
Corsair offer longer warranty 7 years vs 5 years...

Aren't both the same?
Or will you take Seasonic X-650 in terms of build quality?

Please, need quick answer!!! Thanks.

The Seasonic G 650w and the current revision of the HX650 Gold is the same unit internally, so they are both good units; however, the HX650 lacks the necessary connectivity for SLI/CFX (2 PCIe cables on the Corsair vs 4 on the Seasonic) thus forcing you to use molex connectors. Because of that, I find the Seasonic to be better.

7 year warranty? Meh ... won't see myself using a PSU for more than 5 years even if it lasts. Probably due for a new higher efficiency lower power PSU by then.
Strange that Corsair only supplies 2! PCI-E connectors ...

I used my Enermax Noisetaker II 485W for 7 years, so it's real chance to use my new PSU for 7 years, also...
According to hardwaresecrets HX650 is Seasonic G-650, but with "different internal design".
What does it mean?
I think, they have different fans...
Yes, 2xPCIe on Corsair is worse, but with molex reductions I can solve it, I'm not planning SLI in these days...
Will you rather choose Seasonic despite the 7 years Corsair warranty?

Hardwaresecrets was comparing the HX850v2 with the HX650/G650. The HX850v2 is a Channel Well Tech build PSU based on the PUQ-G platform, while the HX650v2 is a Seasonic G 650w internally. Therefore, the HX850v2 is a different design than the HX650v2 and G 650.

IMO, since you are buying a new PSU, rather than going with PSU that will forces you to use molex adapters, get a PSU that have the necessary connectors in the first place. Molex connectors make the setup look rather ugly/messy. Since you aren't going to SLI/CFX, then I guess it doesn't matter, so it's up to you on which on you would want to get. Go for the Corsair if you want a 7 year warranty. But I would have a look at 450/550w solution for your system.

If you in the US and set on getting a 650w unit, you could also have a look at the Rosewill Fortress 650w for $102, btw. There's a non modular Capstone 650w for $64 as well.

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...
post #57 of 75
I would like to ask owners of HX650 (with gold efficiency) how loud is the fan?
I'm bit confused because many owners of HX650 V2 have problems already with fan, who have mostly chirping issue...

Seasonic anyday. For most places cheaper more native PCI-E connectors and seriously i WILL NOT use a PSU for more than 5 years. Or even 3 years.
And also you can't pull too much current just using the converters because the molex are only 18AWGx1 .. And also the connection won't be too good and you will get voltage drops

Only reason for me to start thinking about to choose Corsair is the 7 years warranty over 5 years warranty and the same price in my area.
Will you choose rather Seasonic despite this two reasons?
It looks like HX650 have common chirping problem despite the different fan from G-650.
Will you pay 15% more for X-650 instead of G-650?
Thanks.

Its also good to know your PSU wont blow up/shutdown if you do run everything on 100% load, thats why i would reccomend a bit more then 750W.... Say 850 or 900W.
Some headroom for the PSU to breathe and for future upgrade's)

Your PSU isn't going to fail at maximum capacity if it's a quality unit... Buying an extra 200-300w is a complete waste of money unless you're planning on buying 3-4 GPU's. The chances of there being single GPU cards in future that need more than 750w in a CF/SLI config is slim to none.

You do not need to baby your PSU.
