Corsair Professional 650HX?

post #1 of 10
Thread Starter 
CPU: i5-2500k OC'd to 4.5 gHz with Cooler Master Hyper 212
HDD: 1 TB x2
GPU: HD 6870 2x CF'd both OC'd
RAM: Corsair Vengeance 2x4gb
CD/DVD reader/burner

Is Corsair Professional version 650HXw good enough? Why do people get 1000w PSUs with similar specs as I do? I've also seen some Alienware desktops that are weaker than mine but have more than 850w...

You might squeak by with 650, but i would get at least 750+ if you can.

650w is fine, any more than that is a waste of money. There may be better choices than the HX650, though.

Because they're idiots.

Get the hx750 or tx750 v2. A little breathing room is not a bad idea for future upgrades.

You'll be good. I feel confident adding another 6970 to my setup with my 650HX. You have to realize its a high quality top of the line PSU and not like other 650w PSU's.

Again, it's a waste of money. A rig with two 6870's won't come close to using 650w, even at full load.

I've been running 2 470's, 5 HDD's, 5 Fans and lights on my HX650 for months.

You should be fine.

For peace of mind, head on over to the link and get Phaedrus PSU calculator.

But as most of the posters have said here, you're fine with your HX650 with your setup with room to spare.

I'm prefer a little more breathing room, but you can't go wrong with that unit.
