Power supply to get?

[disaster101]

hey got a fairly new system got a

ASUS Crosshair V Formula 990FX
phenom 1090t
vengeance 2 x 4gb 1866mhz
antec 750 watt
5770
and a haf 132 i think it thats the name at least


anyway im moving up to the 7970 in a few days and need a new power supply for main reason being it needs 2 8 pin connectors or 6 pin cant remember at this point in time so would like to know what would be a good psu for this card. ive got up too £100 to spend on it at the max. plus needs to be a uk site or just let me know what the psu is and ill look at it thanks in advance .

The Antec should theoretically work with dual 7970s but it'll be running close to it's max output if you stress your computer.

I'd recommend.. Corsair TX 850 / HX 850 / Seasonic X 750 / XFX 850 / and select higher end models on Antec / Ocz/ Thermaltake ... 2 cents.

@ Lilo: You can't be serious.

Disaster: For a System with (1) HD 7970, AMD recommends 500W PSU with (1) 150W 8-pin and (1) 75W 6pin PCIe power connectors. In testing at Guru3d, a highly overclocked system with a stock HD 7970 consumed 335W: http://www.guru3d.com/article/amd-radeon-hd-7970-review/8
What's the model of the Antec PSU? That PSU should be MORE than sufficient for your rig....it's probably enough for almost any SLI/CF rig.

its just an old one and oops i meant artic cooler sorry dont sell them in the places i go on now and they only go up to 4 pin plus 1 6 pin adapter

 

[lilotimz]

Oh .. Thought he was talking about going crossfire 7970s .. woops! LoL

Yes. It's more than powerful enough for 1 HD7970.

 

[disaster101]

lol no well not for a while i mean i had a 6970 for a while but sold it to my mate with the psu cos i have a long warranty on the card and got my old psu that i originally gave him about a year or so ago but yeah as i said it only has 1 6 pin adapter so mainly wanted to know what would be a good psu for the card and also peoples views on good psu's they may have that would run the card

 

[Rugger]

What's the model on the PSU? The 7970 will likely have a molex adapter that you can use for the 8-pin. You probably have more than enough juice in that PSU.

If you want a new PSU, then a short list good mfrs: Seasonic, Corsair, XFX, and Antec. There are more, but that's my short list. Do you have a budget? Websites that you typically use?

 

[disaster101]

i just dont want to go over £100 i mean by a few quid i dont mind and i know i could get a adapter for it but would personally rather get a new more up to date one and can keep this one as back up like my old 5770 i have ^^

The XFX Pro 550W is more than enough for your rig with 44A on the 12V rail. Made by Seasonic for XFX and has a 5yr warranty: http://www.scan.co.uk/products/550w-psu-xfx-pro-series-core-edition-p1-550s-ukb9-85-eff-80-plus-bronze-sli-crossfire-eps-12v-fan-at

i should add i will be doing cross fire after a while wouldnt i need more juice than that for it?

 

[LordBlake]

Just search in newegg for psus with more than 60a in 12v and you should by fine for any cf or sli ( if it has 4xpci-e connecteors it'll be easy for you)

 

[lilotimz]

LoL then my recommendation's stands if you are looking to crossfire.

Corsair TX 750 / 850 - HX 750 / 850 / Seasonic M12II , SSK or whatever (all seasonics are excellent), XFX 750 / 850 Pro or Core (seasonic based units), Antec TP 750/ 850...etc.
