Will this Jeantech PSU be good enough for a hd 7950?

post #1 of 13
Thread Starter 
Hi guys im new here "Hello" smile.gif

I have built a few PC's now and my bother is looking to upgrade his system to match mine,

He wants a hd 7950 and already has a 2500k and a Jeantech 600 psu

Big question will this psu have the guts to run it , im unsure about the dual 12v rail stuff

I just put a 7950 in my system and it killed a 780w psu from Maplin's ( G7 POWER total crap ) i then put in the XFX550w pro and all is good,

If this won't run it i will get him the XFX or if you guys have a better suggestion?

Pic of psu label below

Thank you for reading

Well,

Yes, 550w would be enough for that setup however, it's XFX and they don't make amazing PSU's.... If it were a seasonic or something then there wouldn't be any doubt. But yeah that should be ok.

Oh I thought you said that was the one off of the XFX box, I don't think it'll have enough amps on your 12v rail... I think the AMD card pulls around 25a
Quote:
For a system using a single reference clocked Radeon HD 7950 graphics card AMD specifies a minimum of a 500 Watt or greater power supply. The power supply should also have a combined +12 Volt continuous current rating of 30 Amps or greater and have at least two 6-pin PCI Express supplementary power connectors.

Got that off another site, I wouldn't be happy using that PSU in that case....

Your XFX unit is indeed Seasonic made.

Anyway, that's a ~350W system at full load, so you won't need a large PSU at all... but you will need one that's not made in the back seat or a tuk-tuk, like the Jeantech you have there.

Where will you be buying a new unit from and what's your budget for this purchase?

LOL i had a feeling Jeantech wasn't a great psu

Im in the UK so bout 60 - 80£ would be the budget & will more than likely buy it online

He doesn't have a 7950 atm either, he just had ago on my rig and see the massive improvement over his machine - he has a 2500k 8gb ram and a 2009 low end gpu.

I recently went from the GTX 275 to the 7950 and i love it so far, so i had that in mind for his system too.

Im running atm

955be oc 3.8ghz
8gb ram
7950
3 hdd's
and 6 fans on the xfx and it don't even break a sweat even while running prime or furmark

But if you have a better gpu and psu setup for around the same price would love to hear the suggestions

Anandtech puts the 7950 on it's own being OCCT'ed at 350w though.

Total system power consumption, registered at the wall (if you're talking about the Bench section). wink.gif


@OP, the 7950 is an excellent choice, the only thing I'd suggest over it is a 7970 smile.gif... so, if budget allows, go for that.
As for the PSU, it's hard to beat the Core 550 at current prices (below 50 pounds)... but if modularity is important then here's a nice pick at a good price also.

Ah fair enough

Although, if he's gonna go with a 7970 then the ghz editions aren't much more expensive and those are binned processors... They overclock like proper champs biggrin.gif
