Corsair HX 650 for system 2500k + SLI 560 ti - Page 2

post #11 of 29
If the OP has a UPS with software, or watt meter, they can measure how much the system pulls from the wall. I'm going to say the 650 will handle the setup in question just fine. Really.

As an example, look in my profile, you'll see a system called "Tricorder." That's powered by a TX650V2, and pulls a little over 300 watts in a usual encoding spurt, or game. That is from the wall. If I slapped in another 5850 I'd be around the same power use, and have no doubts the 650 will hold it...yet it isn't the HX (which is supposed to be better).

I don't know if he made a typo or not but either way it would be correct, a 650W is fine for a pair of 570s.

Actually the TX650V2 is a better unit than the HX650, with the obvious downside that it's not modular.

It wasn't a typo and yes whilst a 650w PSU can handle SLi, I wouldn't make a habit of it. Since the HX650 is such a high quality PSU it would manage it, if you were talking about a generic peice of crap then probably not.

TX isn't better than the HX, it's got the same guts just no glory

Matter of opinion there. I much prefer hard-wired connections; less chance for heat, resistance, or electrical noise.

No, really, the TX650V2 is a better unit than the HX650. Different guts, too.

I get what you're saying, but really the amount of resistance added by the modularity is tiny, and with all the awesome modular units available with extremely low ripple, I think that's also a non-issue

Your very good 650W PSU is fine. Even if you overclock.
