Do I need a psu

[2fast4thetown_down]

I have an i5 2500k and I am getting 6870, I have a 460 watt cooler master do i need a new psu to use 1 6870

 

[rolli59]

Theoretically not but what exactly is the model name of your PSU?

 

[2fast4thetown_down]

It is a coolermaster elite 460

 

[rolli59]

I would say get a new one even if it runs it http://www.hardwaresecrets.com/article/Cooler-Master-Elite-Power-460-W-Power-Supply-Review/1005/9

That is why I do not trust CM power supplies even if I like their cases & coolers...

itd be really tight with the 460. not really enough wattage on the PCI-e rail output. a 550w is barely enough with no headroom for anything else. id think the minimum should be a 600w. corsair, silverstone, seasonic would be some strong choices.

Seriously 600W? Modern PCs consume much less power than most people think. Example: http://www.silentpcreview.com/article1245-page3.html
A system with a 2500K and an HD 6870 consumed 271W at full load.

2Fast: Is your CM Elite Power 460W enough? Yes but it is a very low-quality 400W PSU with a liar-label claiming it is a 460W. At high loads the PSU has excessive noise and ripple and these conditions damage components. I recommend getting a quality PSU to replace your Elite Power PSU...it ain't so elite.

I really like the ocz modular. I think this is what I am going to do get the 6870 use the cooler master, save up for the ocz modular get that and be happy.

 

[2fast4thetown_down]

The XFX would be my first choice.

Why is that?

 

[2fast4thetown_down]

SeaSonic parts.

Is 550 enough or should I get a 700 to be safe and be able to make more future upgrades, ie water cooling secound 6870,etc.

 

[rolli59]

If you want a second HD6870 down the line you might as well go with a bigger unit. 600watts will do it but you will need 4 PCIe power connectors which from most manufacturers means 750watts.

Put 4 in my post above all $90 after MIR.

 

[rolli59]

The OCZ is fine but the TT no go.

 

[2fast4thetown_down]

Is 550 enough if I do not get a second card??

 

[rolli59]

Yes it is plenty 500watts is what is recommended by manufacturers and people run the HD6870 of Corsair CX430.
