Hi! :hello: 
Im going to buy a HD4870 in the next week.
I have a Thermaltake 470W power supply now. Is it enough for a HD4870?

My PC:
Gigabyte EP45-DS3
Core 2 Duo E8500 (not overclocked)
2x2GB CSX CEC FAN KIT 1066MHz
[HD4870]
Samsung 640GB HDD
Thermaltake 470W power supply

yep that should do the job. recommended is 500w but those thermaltakes have good 12v lines so should work ok.

You should be set.

A Review of a 4870x2 with QuadCore QX9650 @ 3.2 Ghz peaked at 410w.

Having a single 4870 and non-OC'd Dual should drop that number quite a bit.

As blade stated, Thermaltake's are decent CPUs so what you have should be just fine.

Apologies for piggybacking, but I have an Asus hd4870 Dark Knight coming. I planned on using an Antec True Power 550w circa 2004 (no six pins). Will this suffice with the correct adapters or should I update my psu?

um. it should work. as long as u have molex to 6pin pci adapters. but yes, a upgrade would be worth it. maybe a corsair psu no larger than 750 is needed

How many amps do you have on the 12V rail(s)?

12v is 24amps Model is True550. I remember it was a pretty strong PSU back in my OC days. It has 7 pin atx plugs and wont power much else other than one sata hard drive and optical on a 780g mobo with the Phenom 9950.

Thanks for the quick replies
