Hello all,

Alright so I have a Hp Pavillion a6720f And Recently was suggested to get a Sapphire Radeon HD 5670 512MB card. I was looking for a good graphics boost for a not so good computer and cheap. I have a 300 W psu.

Would a SAPPHIRE Radeon HD 5670 1GB 128-bit be compatible with my computer? If so, Would I have to upgrade my PSU? Because the Newegg site says 400W Requirement.

The PSU requirement is usually overstated by manufacturers therefore they say 400watt. I have every reason to belief that a HD5670 would run on your PSU as long as you don't overclock and don't have multiple casefans many hard disks and/or optical drives.

Hmm you might be in some trouble with the power requirement
It seems as though you only have a 300W power supply and that's pretty low, and with the cards minimum requirement being 400 W for safety reasons (or just having enough power to run) I don't think you'd be able to run the card if it truly is only 300W

The card has a TDP of about 63Watts I think. HD5570 is 54.

Just used the Newegg power supply calculator (not sure how accurate it is) but I put in the specs of what the normal Hp Pavillion a6720 has and it says it uses 326 Watts, which means that your computer would probably be needing a power supply upgrade as well since integrated graphics don't take much wattage compared to Dedicated

I got 243 using this.

Are you sure i just used that link and i got 327 watts... The only things that may be wrong on my thing are i put 6 USB, because that's what's avaible (Not sure if it's asking whether those 6 USB were in use or just there to be used) and 2 firewires

Im trusting you Shadow :]. lol Because I love hearing good news, 1GB would run performance alot better then a 518 mb right?

Oh no, the HD5670 isn't fast enough to fully utilize 1GB of V-RAM. Instead, opt for the 512MB one.

For a video card a 512 MB is going to be weaker than a 1 GB, so yes 1 GB is faster, and I'll just default to Shadow's opinion on this one since he does have the silver badge in graphics lol... but if you can't run the video card it's probably going to be the PSU's fault

Probably would've had Gold by now, but half the people don't know about the Best Answer function, which r_...mixer(?) forced people to do, which gave me some points.

I don't think phenoms went over 140W, so he's good there. GPU+CPU=200W, leaving 100 for everything else.

So just to be clear though... On the extreme power supply thing i select, AMD phenom II x4 9550, 3 sticks of ddr2 ram for 6gb, 6 usb avaible, 2 firewire available, one Sata, one DVD+RW, 3 pci and 1 pcie 16x... I get 298 Watts...PSU is 300, and this could be a wrong measurement because maybe it wants the usb/pci slots filled if they have something in them rather than just being on the mobo if so (taking off 6 usb/ 3 pci/ 2 IIE(firewire) brings it down to 230 watt with one pcie slot occupied which is what you need... The latter of the two is probably the correct choice since it seems to make the most sense
And wow it almost seems like i created this thread... (Sorry just dont want to say the wrong thing and then carry on with saying the wrong thing on other topics)

When you select those ports, the calculator thinks those ports are being used. He'd have to have 2 firewire, 6USB, and 3PCI cards running at the same time, I believe.

If it cant utilize it, will it still have a little bit more performance?
