ATI Radeon 6670 and 220W PSU

Hi,
I have the HP slimline s5660f with a 220W psu and the ATI radeon 5450.
The PC has a quadcore phenom X4, with 12 GB of RAM, and a hard drive.

I am upgrading the 5450 with the Saphire low profile ATI 6670 card. Some comments on the web say that the sapphire card can manage even with a 250w psu, even though AMD recommends 400W.

http://www.newegg.com/Product/Product.aspx?Item=N82E168...

So my question is:
Can i manage with the existing 220W PSU, or should I purchase a 300W (or higher) seasonic TFX power supply ?

Thanks for any suggestions.

I would recommend getting a 300W or higher TFX PSU so you don't risk your PSU going boom.

hpdeskjet that PSU will not fit in a slimline case. Slimlines use a long rectangular PSU type known as TFX not the ATX's that we are used to.

It works on a crappy 220W PSU. So you will be fine. But there is a risk of it blowing up. Go for something like an Antec EA380D for ~$30 on Amazon. Good enough to run a HD6850.

the antec ea380d will not fit an hp slimline case. Im not even sure if the tfx fit but you have to check the case.

check if you can see what kinda of amps your psu can pull on the 12V rail. If its above 15 then you won't have to worry about the 6670.

Thanks for the comments. I think the 220W TFX PSU specifies 16A on the 12V rail.

I need to confirm. But if that is true, i guess I still need to upgrade the PSU to 300W or higher, right?

16 amps should be ok as the 6670 only draws max about 60w of power meaning you still have about 100w for the rest of your system which Im sure draws less especially since you need to put things at max load for it to reach such high power draw which won't happen unless you do stresstests.

Sorry about recommending an oversized PSU. Didn't check the dimensions of the case.

No probs. The slimlines apparently use a TFX form factor psu, and my current stock psu has the TFX dimensions.

Thanks caqde and esrever.
I am a bit nervous about it, but I guess I can install the card and see if the system is stable with the current 220W psu...I don't overclock or anything.

maxinexus, do you have a HP mediacenter PC that could not run the 6670 with a 300w psu ?

No HP, it is my own build. 300W PSU was not high quality at all. When running 3D game or movies pc just restarted. Works great with antech PSU.

I did put in the Sapphire low profile 6670 card into my HP slimline, and it is working fine so far, on the stock 220W psu. Have not really stressed the system much, though...
