SS-520H1U with 4890

[Jorenm]

I'm upgrading from an 8800 gt, and I'm wondering if this will work.

Will this:

be sufficient to run this:

Right now I have an 8800gt, rampage II gene, i7, 6gb of ram and one hard drive running on that PSU. I get a 6 pin PCI-E from the 8 pin EPS http://www.playtool.com/pages/psuconnectors/connectors.html#eps8

I'm not sure where best to get the 2nd pci-e from.

This article:

States "Each added 4890 card means another 190 Watt (peak) on your 12 Volt rails. 190/12= 16 Amps per graphics card."

So I don't think it would be wise to split my 12v from the 8 pin EPS connector into two PCI-E.

Should I daisy chain off my case fans? (I'm assuming they're the lowest draw of the 12v rails).

A 4890 actually uses about 120W at full load, which equates to around 10A. Your PSU is a single-rail +12V unit with 40A, so you'll be absolutely fine.

So I can split my current single PCI-E into 2 PCI-E and it's no problem? That's definitely the easiest and least messy.

 

[Zero82z]

Splitting a PCI-E connector usually isn't the best idea, but as long as you don't overclock the card, you should be alright.

Cool, thanks for the input.
