So this is the build that I've settled upon. The PSU is not my most knowledgeable area, and I'm pretty sure the one I have is sufficient but I'm tryin to trim off unnecessary dollars so I wanted to see if anyone could recommend a cheaper one without losing required power.
It comes in a good combo. If I replaced it I'd wanna keep a good RAM pairing.
G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL7D-4GBRM
That is more power than actually necessary for your build even with a 2nd HD 5850.
But the price differential between the 750TX and 850TX is only $10.
And a Corsair 650TX might work out OK but if you'd want to overclock the CPU and both HD 5850s the 650TX might be a bit light on power.
I'll recommend either getting the XFX 750W Black Edition or the Corsair HX 750W (whichever is cheaper).. They'll both exceed your current power requirements but will adequately fit your future upgrade plans.. Additionaly, both of them are very efficient (80+ silver certified) and modular which helps immensely with cable management..
In mixing around the components in my build I came across a combo deal with my 5850 and another power supply... not sure if it's worth switching from the corsair/RAM combo listed above and buying some RAM solo
It's a SeaSonic X750 Gold 750W ATX12V V2.3/EPS 12V V2.91 SLI Ready 80 PLUS GOLD Certified Modular Active PFC Power Supply
Hmm. My entire condo is a cluster-F of cables. not sure if Eliminating a few I'll never see is worth almost $50 bucks. My idea is that the Corsair seems to be a solid PSU that'll fit my needs and then some - and it's a great + RAM combo
Well the Seasonic is modular and you cant beat a 80+ Gold certification. That's why its pretty OK in pricing considering the 80+Gold certification and being modular. 80+ Gold certification PSU's are very rare. Look at AX750 from Corsair... Its only $10 cheaper than the X750. So why not.
But in a way the Corsair TX750W is also a good PSU. No worries there.
You can have that or the AX750W from Corsair. You cant go wrong with either PSU's. Both have pretty same specs and both are gold certified. Unless you have extreme bad luck and end up having a faulty one. That's pretty rare. Since you are getting a combo deal on this one, you can go for it.
