PSU Choice

[Aeiri]

Having a hard time making a final decision between a few Corsair/Seasonic models.


Seasonic X650
Seasonic X750
Corsair HX650
Corsair TX750V2

Anything more expensive than these are outside of my budget. Rebates are not a factor, as I have to worry about the right now price to be able to afford them. If only you could pre-apply rebates T_T


Will be running a mild overclock on a i5 2500k and 1x 560 Ti. In a few months there is a possibility of me going SLI but theres a chance I will just stay single card as well. I've read many reviews saying these PSU's can handle 2x 560 Ti just fine, but I am uneasy about running so close to 100% load so often if I go SLI.

The only reason I'm considering the X750 is because I checked today and it seems to be $10 cheaper than the X650, and I cant find any evidence of a sale on it either.

Also I hear the Seasonics being very highly recommended but I read several reviews of people saying it has a big issue with coil whine(even many positive reviews still list this as a con). The negative reviews stick more in my brain than the positives so maybe I'm just freaking out.

Corsair PSUs are just rebranded Seasonics. (aside from the cheapies - those are made by random no-name brands)

Newegg has the Seasonic X750 for $120(X650 is $130).


TX750V2 is $105, HX650 is $115.


$120 for a 80 Gold, fully modular PSU is a price I don't mind paying, I just have no idea why it is cheaper than the X650 when it doesn't seem to be on sale(I cant find another site selling it for less than $160ish.

Should I pick it up for $120 or would you recommend another? I'm scared to wait till Friday on this one since the price might change back to higher.

I guess get the Seasonic X750. Amazing quality, 750 watts Is more than enough for your set up and will support more add ons In the future.

I ended up buying the X750 for $120 last night. Good choice, they updated it to be a holiday blowout.

Good choice.
Don't worry about the wattage. The PSU can handle 2x 580s in SLI, and you have only a 560 Ti.

All of them can handle SLI GTX 560 Tis.
The two SeaSonic ones are the best ones.

EDIT: too late! :]

I like the Enermax MODU87+ GOLD 600W Power Supply.
+ Gold efficiency level
+ Enermax
+ 600W, enough for GTX 570 SLI

You need at full load with a 2700k + GTX 580 => ~450W.
More than 600W is just overkill and hurts the PSU efficiency => more wasted heat.
