Is my Earthwatt 430W enough?

post #1 of 13
Thread Starter 
I am wondering if my Earthwatt 430W is enough to power my ATI Radeon 4870 1GB that is coming soon. My rig that the PSU is powering is in the signature.

Thank you

ATI Radeon™ HD 4870 Series System Requirements ATI Radeon™ HD 4870 System Requirements ■PCI Express® based PC is required with one X16 lane graphics slot available on the motherboard
■500 Watt or greater power supply with two 75W 6-pin PCI Express® power connectors

Your PSU has 1 6 pin. can u mod it, maybe.

Not recommended. Even for a 4850 is recommended to have a 450w PSU.

Contrary to popular "YOU NEED a GZILLION Gigawatts" comments I say give it a go. I ran a Quad at 3.4 and two 8800GTs in SLI on this PSU for almost a year.

Run it, watch it work, laugh at those who told you not to.

Run it, watch it fail, buy a beefier PSU.

Those are your options. Good luck bro!

Your PSU has 1 6 pin. can u mod it, maybe.
You could use a 2 molex to 6 pin converter.

If your PSU has 1 six pin, your GPU is requesting a certain wattage and your not meeting any of the SUGGESTED requierments... wouldn't u safe guard yourself and get something a bit better?

By the way, the OP has 4800+ posts and a 428 rep... I think he knows what he wants to do.

Thats EASILY enough power. Go for it . Just make sure you use an adapter for the other 6pin (obviously).

I've run my system with one 4870 on the exact same power supply (assuming it's the EA430 and not the EA430D; that would still do though). It ran quite easily. An overclocked quad core and a 4870 shouldn't break 300W or so. You do need a molex to PCIe adapter, but the actual electronics are more than capable.

Yea I have the EA430 not the newer version. So you can overclock the 4870 without any problem?
