Just upgraded my core computer, more options?

About a year ago i upgraded from a amd 4400+, 7800gtx, 2gb ram, and a dfi ultra-d. I upgraded to an older generation core 2 duo and a 9800gt, i think. got the whole setup for basically free after i sold off my old parts. I just recently upgraded to an MSI P55-GD65, i5-760 currently at stock speeds and added a 2nd 9800gt to run sli. Ive got 16gb of ram in the mail along with a new storage hdd, dreaded 7200.11 finally bit the dust and is getting RMA'd

Ive run all this on the same psu I had with the 4400 and dfi setup from back in 2005, it is an old OCZ modstream 520w. right now it gets the job done but back when I was 16 I made my own wiring setup specially for the dfi board and everything i had back then, did I mention I was 16 when I did it and I think thats all i need to say haha. Anyway, im currently using a bunch of converters to get the sata power and pci-e power to the cards.

It is working just fine but would you upgrade the psu?

I was looking at the corsair TX850 or seasonic s12II 620. I know the PSU is the heart of the system and I like to make sure ive got extra power to keep it for a long time. Point in case the OCZ 520 ive use for the last 7 years, but I'm also on a college budget. Let me know what you think.

Which model 9800 GT do you run? I believe some use 2x 6 pin PCI-E connectors? Others use a single one? This would determine the PSU for me..

But if they're single 6-pin's grab a Corsair CX v2 500W. It'll run everything fine.. Comes with 2 x 6+2-Pin PCIE connectors..

Corsair CX V2 500W with promo!

said screw it and picked up the tx850m, figure that will last me a long while.

It will.. It's overkill, way overkill for your system. I would've stuck with the 650W version if you wanted a bit of headroom. (650W will run dual GTX 560 Ti's or HD 6870s). But glad you got it sorted at least.
