post #1 of 5
Thread Starter 
Yo what's up smile.gif

I was just wondering I'm soon gonna be getting a new GPU and i'm on a strict budget : I could either get at 6970 or 7850; and I just would like to know if this psu could run it: http://cdn.powerlab.vn/home/wp-content/uploads/2011/04/FSP-HEXA-500-11.jpg

My system:

Phenom II x 4 850 (max TDP 95w)
4GB DDR2 RAM

Thanks guys any help would be greatly appreciated smile.gif

This is the Intel CPU area, but anyway

If you want to be safe, save a few more dollars for something like this, which I just got

http://www.directcanada.com/products/?sku=16950AC3542&vpn=P1450SX2B9&manufacture=XFX

Low end budget PSUs put out noisy/dirty voltage which is bad for everything, and usually can't put out their labeled wattage.

Check the PSU area, there's lots of know-how there

sorry man! didn't see that frown.gif
that psu is 450w and it's a bit cheaper than the one I'm considering! my one is 80+ bronze so it couldn't be that bad couldn't it? frown.gif The recommended PSU requirement is 500w for the 7850 also. Thanks !

The wattage requirement is based on people using bad psus. If you have a high quality psu, any one will do. A 400w+ high quality psu is literally huge overkill for any single card. A high quality 350w+ psu really could handle anything like the 7850, etc.

xfx cores are insanely high quality psus. that linked psu is a really, really good deal, and way better than the psu you listed, and capable of much more power too. Just because a psu can do 500w also doesn't mean that it can handle a transient change to that load well either.

also bronze ratings, silver, they dont mean anything. it's just a designation granted to the psu if they send some stats in a hermetic testing environment. plenty of bronzes fail at efficiency and non-bronzes are very efficient.

It's about the quality, not quantity thumb.gif

i swore i posted in this thread earlier and already replied to you... i was under the assumption that you already had that fsp hexa, in which case it'll work just fine, it's just a low quality psu. if you were planning on buying it i would strongly recommend against it. yea the psu you picked out really is that bad.

Oh okay! Wow 350w could handle a 7850?! that's impressive! I don't have the FSP Hexa ... I need to buy a new PSU! rolleyes.gif So are you saying I could easily run a 7850 with a Corsair CX Bronze 430w? rolleyes.gif
