Hi, I got an Ultra 650W power supply along with my 3570k barebones and a 7850.

So I know that the 3570K is gonna be good for at least 4-5 years in terms of gaming performance (I'm not holding my breath for haswell), if not I can OC, but the real problem is the graphics card.

I'll probably upgrade GPU in 2-3 years time, and just wanted to know if this power supply would be good to run a gtx680 or gtx760, or a "future" radeon 8850.

The specs say 38A on 12V from tigerdirect, but the box says 64A on 12V, so I emailed ultra and asked them what the specs on the LSP650 was and they told me 64A

So was wondering, will this PSU run a 3570k (maybe OC'ed but to a max of 4.5ghz probably around 4ghz just for kicks) and a future gtx680 or above?

64A on the +12V is equal to 768W, that is impossible for a 650W unit. Their website says 38A which is 456W. You've got a 500W unit labeled as a 650W unit; assuming it can actually deliver the 38A of +12V cleanly.

There are no reviews up for this unit anywhere I can find, but given that it's manufactured by some ShenZhen RuiSheng Yuan, it's probably not very well built and only uses low quality chinese capacitors. Based on the +12V rating it probably can't do 650W, but you won't need to stress it that bad. With a 3570K and 7850 it's probably going to do fine, it won't even reach 50% load. Still... I wouldn't be comfy having an Ultra PSU in my rig, I'd sell it and buy a good quality 500W-600W unit.

Um i agree that's their website, but thats actually not their website, thats taken directly from tigerdirect, so you're saying if I replace with a gtx680 this psu might fail on me

I think it's Tigerdirect copying info from the manufacturer's website, not the other way around. It seems Tigerdirect is closely tied with Ultra. http://en.wikipedia.org/wiki/Ultra_Products

GTX 680 uses less than 200W, it should be fine as far as the PSU specs are concerned. It supports any graphics card that requires 2x6pin PCIe connectors. So it does also support 7850 crossfire.

Even if you put no load on it, it will fail. Ultra is a cheap low quality brand that offers sub par performance with dangerous lack of quality.

Get something like a CX500 or CX600. They're usually very cheap and they're good enough for most situations.

Maybe a bit late but that's the point:
I'm using the Ultra LS 650W for over 10 years and just upgraded my machine to R9 5950X + rtx3060 - no problems after all these years!
Of course we don't know if the specs change for this PSU in 10 years...
