Corsair 650TX or 750TX

post #1 of 15
Thread Starter 
I've heard you can push Corsair PSUs past their designated wattage without problems most the time. At the moment I have a Phenom II X4 965 that I most likely will have at 4GHz sometime in the future. Going to go with 2x4GBs of RAM eventually along with a second 6870, possibly another SATA hard drive or two, an SSD and a BluRay drive.

I was wondering if anyone with a similar setup was fine with just running a 650w Corsair or should I step up and maybe get a different brand 700w or just get the Corsair 750TX. Trying to save some money while still making a good choice on a PSU. This BFG won't take a second GPU, I'm sure of it, haha.

Thanks ahead for any info.

If you have the money take the 750TX, you'll have more room for upgrade and it's always a good idea to have at least a 20% margin in terms of power consumed/available, I have the 750TX and I'm completely satisfied.

TX650W ~52A
TX750W ~60A

I'd get the TX750

For this intended setup, a quality 550-600W would be fine. But for even more headroom and also for a superior PSU at a similar (nearly identical) price to the TX series, I recommend the 650W Antec TruePower New:

AMD says a system with two 6870s in it would only require a 600W which is why I said even a quality 550W would be fine.

Take a look at the AX/HX Series they are much better then the TX line if money is a problem like Two Cables suggested the Antec TPN is a very solid PSU and not expensive compared to corsair. If you have a little money on your side consider the Seasonic X line.

Thanks for the input guys. If I see the 750TX on sale for around $90 I'll grab it or if that 650w Antec goes for $10 or $20 cheaper, I may get that instead. I doubt I'll get two 6950 or 70s in the future or any one or two things that are more than enough for what I plan as of now. Two 6870s will last me atleast until the 7 series come out. Anywho, thanks again.

If you're going to stick to just one 6970, then either don't get a new PSU, or get the 550W Antec TruePower New.

By the way, the 650W Antec TruePower New is $89.99 + $3.99 shipping, while the Corsair TX650 is $89.99 shipped. So, that's a difference of $3.99. So that means if you bought the 650W TruePower instead of the TX650, then you'd end up with a higher quality PSU, plus it would be partially modular. So it would be a win-win situation.

Om nom nom NewEgg. Thanks for pointing that out. I was thinking the 650TX was $99 for some reason.

Neither of the TX units. They're both CWT PSHII units and build quality is just ok. There are much better options.
post #10 of 15
Yeah. And those models mentioned (TX650/750) are old hat and will be replaced with updated ones soon. As they are now, you're not really getting your money's worth. Get something like the TPN suggested above.
