I bought this corsair psu last month during a shell shocker.



Then I was going to buy a graphics card, but one of my required textbooks was $250 and I couldn't find the pdf to torrent so I had to buy it.

I was originally going to buy a 7850 but this 7870 le/7930 caught my attention.

I plan on buying a i5 3570(unless they announce those haswell cpus soon) and I don't plan on OCing it.

Hi - realhardtech suggests 500w for a system with a 7870, that has some headroom built in.
I don't like to suggest a psu that is more than 50w below what realhardtech suggests.

I'm fairly sure the sys will run on a 430w unit, but the 7870le as I understand it consumes
a little more power than the stock version. I think you are cutting it a little close.

If you do go ahead with a 7870, you need a molex to pci-adapter (some gpu's include one)
as the 7870 requires two and the cx430 has one.

In terms of amps, your psu is suffice even for a 7950, the 7950 requires about 25A, the psu has 32A on its +12V rail.
You'll have to use the molex to pci-adapter that's included in the package of the card, since it requires two 6 pin pcie connectors.
You'll be cutting close, but it might do.

They "might" may end up messing up all my components... :??:  I really might have to go with a 7850 to be safe.

Corsair PSU's are top tier and are very reliable. Personally if it only has a single PCIE cable and your card needs 2 then I would upgrade the PSU.

I think you get the gpu you want & give it a try. It does
have (as dj pointed out) 32a on the +12v rail and that
is a more important spec than tot wattage.
A system with a 7870 or 7950 don't need near
that many amps on the +12v rail, so get the gpu you want.

Tom

I should have been more assertive when I said I was fairly sure
your sys would run on the 430. With the 32a on the +12v
it will run, and no harm in using a molex to pci-e adapter.

I wouldn't reccomend it but it might do.

Generally I'd reccomend 550w for high/mid end single card+mid-end CPU and 750w for dual GPU+Mid/high end CPU but 430 may be enough, however, a surge or short will certainly cause a shutdown, if not permanent damage(depending on the quality of the PSU, components may be damaged, and considering CX series are rebranded OEMs, I wouldn't bet on it).

I may just have to save up $20 and buy the 500w modular one, I'm going to be using a bitfenix prodigy which is a mini itx case, so I wanted a modular psu to help keep it clean. But I don't think I'll be able to afford the rest of the components even if I only go $20 over lol.

The card will do for that psu, it has more amps than required, that cpu doesn't draw that much, i you can get the i5-3470, it's cheaper and will have the same performance as the i5-3570.

Lets say I was to buy a cpu cooler like a Hyper 212 and OC, what would be a safe ghz to overclock to?

You don't need an aftermarket cooler for those cpus, they don't have the multiplier unlocked, so you can get 3.6 ghz with turbo boost, it's possible to raise the turbo multiplier by 4 bins with a z77 or z75 board for 4.0 ghz.

I was referring to the 3570k :)
