Well, i think its about time to upgrade my old 500W SeaSonic. Its served me good through two builds now, but i think its time for something with a little more power. I'm getting ready to upgrade my 9800 to a 260 Core 216, and my 500W doesn't quite meet the recommended specs for wattage or +12V amps. I also figure it would be a good idea since i'm already running a pretty heavily overclocked system, and will be throwing a good OC on the 260 when i get it.

I've been looking at these two: Corsair TX650 650W or this: OCZ StealthXStream 700W

The main thing i'm not sure on is whether the slightly lower rated single 52A +12V rail in the TX650 would be better than the higher rated (72A combined) four rails in the OCZ? I looked around and can't find any real answers to that.

I'm looking to spend $100 or less, so any other suggestions are welcome.

Yeah the Seasonic 500 watt units range from 33-38a on the 12v rail. If it's an older one it would fall short of what you need. I've read the 260 Core 216s require 36a on the 12v rail. I may know someone willing to buy your Seasonic though. Kow_ciller, I believe that X1900XT you're running only needs 30a on the 12v rail like my X1950Pro. Maybe you guys can hook up.

BTW Doc, the OCZ unit is actually slightly less robust in combined 12v amperage. It's actual spec on that is 49a according to what I've read. Either units would be more than adequate to handle your system. Personally I like single rail PSUs, but the price and high efficiency rating on that OCZ make it hard to pass up. They also fit quite well in bottom PSU mount cases due to long cables. [COLOR=Red] http://www.hardware-revolution.com/6-most-important-factors-choosing-power-supply/[/COLOR]

If its either of those, I would go for the corsair. Otherwise, I would suggest you take a look at the PSU I currently own. Its 700w, modular and you cant even hear it. Would be a great addition to that 300 case you currently own. That OCZ isn't really too great. If its anything like the 600w version I had the cables are going to be short and its going to get LOUD after around a year or so of use.

-omen. Dont really need a PSU, I was just using the x1900 in my sis' computer so I could play while im home for easter. I've got more than enough power with my 700w silverstone in my main rig.

Solid unit. Just be prepared for a mile of excess wires in that case

Actually most that comment about the cables say they're rather long if anything.

Honestly I think that first Corsair has plenty of power for you Doc, unless you plan on leaving lots of headroom for upgrades or SLI. I also found a better deal on the second one.

No, i don't plan on going SLI or Crossfire anytime soon. My current mobo doesn't support it anyways, and i dont plan on changing it anytime soon, but whatever i get next most likely will so i was keeping it in mind. I prefer single card setups, but me running something like a Radeon X2 or 295-style card is a possibilty in the future. So, your vote is for the corsair 650 then?

I looked that one up. Looks like a great PSU, but its a little over what i had wanted to spend (so is the TX750). My old SeaSonic will be going back into my AMD system that's in need of a PSU, along with my 9800.

I'll keep an eye out for the PSU's I picked mine up for around $80 shipped. If you're willing to spend a few more dollars I'd suggest you should really pick that (silverstone) up it didn't really impress me when I first got it but the cables are sooo much longer than the Stealthxstream series and power useage is around 20w less compared to the OCZ at full load. But if you have to stick to that budget I give a +1 for the 650w corsair.

Given your budget, current system, and the sound of your plans, I'd say so. The exception would be if you want to carry the PSU over to another build.

Alright, i just placed a order on the TX650.

Also, instead of the 260 i mentioned i was able to score a deal on a Sapphire 4870 1GB Toxic Edition. Most all the review sites are showing those overclocking to around 820-850 on the core pretty easy, which puts it right with the 4890.
