Hi all,
Can my Psu Corsair HX 650 Modular to support a system with i5 2500k OC, SLI of 560ti both OC, 2 x 4Gb DDR3 1866 and 3 Hard Disk?
Thanks for the replies!

lol easily,

I was running the HX650 with my [email protected] + GTX570 +GTX275 6 case fans, my H50 and 6 gb of memory.

It's an epic PSU and you'll be fine

Fantastic!

The only reason I replaced it is because I wasn't sure if it would cope with SLi 570's + GTX275 physx and a custom water loop with a 6 push/pull fan setup on the rad.

my suggestion to u,
corsair hx750
dont take chance with 650watt,
I must admit corsair ax,hx,tx,gs line up psu are great

No way you'll get even close to 650W with that setup. Your HX650 will do like a champ.

... um, no.

The 650 is suitable for Sli GTX570's at stock.

really i made that argument just today and had 2 people go on and on about how it wouldn't... or did you mean 560 instead of 570?

Even if it went past what the PSU says it is by it a bit, a well built high quality PSU can handle the load just fine.

 

[goldjacket]

I say it would work no oc on gpus most likely. All I would do is try it. And test it non oc'd with "occt" power supply test. If it can do that for 10 mins without rebooting I would say your good.

 

[UnexplodedCow]

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.

thank you! i will quote that in my sig now

I found this article!
With a 650 watt easily running a system with 2500K oc at 4.7 GHz and 900 MHz at two 560ti Oc ....

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

 

[p4p3r]

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

 

[Zcypot]

I think this is what you guys are talking about.
