SLI 760 Question

[Torey]

Will the Corsair TX 650

Provide enough power to keep a 2550K OC to 4.5GHZ and two 760's OC running stable?

[Raboo]

Maybe The TX 750m or TX 850m

It depends what other parts you have in your computer, what voltage etc,etc.

I already have the PSU, I have a H90, 2x 120 AF QE, 2x 140MM r2 midi fans, 1 ssd, thats about it, some external usb drives.

 

If it's super close, I guess I will just save up for a 770 or just wait to sli and buy a new psu then, even though this is like 2 weeks old if that.

 

I was peviously running a 965 be oc to 4.0 and 2x 260's oc like crazy on a 650 antec, thought it would be no prob when i bought it, case had like 5 fans, 1 hdd. 2 xternals always plugged in.

 

SLI 760s is supposed to be 340 watts? iirc, 2550k around 80 ish, could the fans mobo and drives make up the rest? seems like a lot to push it over 650. my bad, at peak 2500k is around 150.

That is really close, if not beyond the 650w. I think you should get the 770 instead.

Well technically it has enough power (not by much) but that power supply won't have the connectors you need to power 2 760's. It only has 2 6+2pin pcie connectors which isn't enough for two 760's.

I don't get why my old system ran perfectly overclocked to hell on the same watt PSU and the components took more power, well the 965 took more then a 2550K and 260's is about the same as 760 in power consumption =/

It has molex, and I have sleeved extensions, so it won't look ugly, did the same thing on my old rig.

Ahh ok well I wouldn't personally use molex to pcie connectors because I've seen multiple pictures of people with melted connectors so I just stay away from that lol

[Gamebozzo]

no it wont

[Torey]

no it wont

 

Thanks for the informative

Well I guess I'll just get one 760 and maybe return this PSU this week and just buy a bigger one.

Around 525 watt under 90% load using your listed items. Say 550 max. so yes a 650 watt psu will be more than enough, But ideally you want to hit the 80% PSU load while your system is under full load. SO if you can afford it 750watt is maybe more ideal for better future proof head room. But a very good quality 80 gold 650/700 watt psu will be just as good.

 

*Had to use 670s which run more power as 760s are not listed yet. so yes for sure a 650watt will be more than enough.

**actually i didn't even think of this before but if u see my signature i run pretty much the same system your talking about. and i have 6 Sata drives + 2 SSDs and full water cooling kit. At the socket I'm pulling 515watts full load when OC @ 4.7. And i am running an OCZ fatal1ty 750watt psu.

Alright thanks, I already ordered one 760, within the month I will probably buy another.
