Will 650W do or will I need 850W?

post #1 of 11
Thread Starter 
I'm definitely going for the Corsair HX series but I'd like to spend as little as possible as I've already overspent on the other bit's I've bought.

Now here's what I've worked out my power consumption is...

180W 1080T O/C to 4GHz
160W GTX 460 1GB O/C
90W 9600 GSO Just used for PhysX and Desktops
5W Velociraptor
2W OCZ Vertex2
30W for all fans

Total = 467W

Add 10% for good measure = 513W

So will the HX 650 do or should I go for the 850?

The reason I ask is I've just melted a no-name brand "750W" PSU, that I@m guessing wasnt really rated at 750W. I was running Prime95 and Kombustor accross both GFX cards. After about 1 minute it went pop and now it's dead

650 will do fine.
Also, you must have some beastly fans to be pulling 30w...

Yea the 650 HX should be fine. How much are the XFX Black Edition PSUs?.. If you can get the 750W one for a price close to the 650 HX, i would those are brilliant
But that's just for future headroom the 650 HX will easily handle it

30W was just a max figure. I have 4x 120mm and 1 huge one in the side - It's a cosmos S case. But I left in some head room for a future watercooling system. Which would be another 3x 120mm fans and a pump - and maybe some pretty lights

I was debating leaving some headroom in there for another gtx460 - I dont plan on getting one anytime soon, but it would probably be the next upgrade.

I need to get the PSU tomorrow so that only leaves scan.co.uk as I live nearby and can collect. They don't currently have the XFX in stock

Also I'm liking the 7 year warranty on the HX's

If you want Sli then you'll need a good 750w psu like the antec TPN 750, HX750, Seasonic x750 or the xfx one.

Warrenty on the HX rocks, as does the clean power. I was also looking for an XFX black ed, scan doesn't have them in stock, nor do Aria or Novatech. 600w would be plenty for your rig as is, 700-800w if you do go SLi. I'm seriously looking at the Silverstone Strider+ 850w

650W would do Sli 460's too to be fair.

Would be approaching the limit but it would definitley work.

Still 650W for one card is plenty
