Hi Guys,

Just wanted a bit of advice really. I have bought a Radeon 7960 and need to get a better PSU so that I can use this card. I did have a 850w cheapo pile of turd but as soon as the card started doing heavy workloads the whole thing would shut off. Needless to say this was a silly idea on my part of buy a unreliable PSU.

I was thinking of getting a Akasa Venom 750W for this card, going on my specs below would this work do you think?

AMD FX4100 - 3.6GHZ (Overclocked to 4.5Ghz)
X1 SATA drive
X1 DVD-Writer
X1 Stick of DDR3 RAM

I've made a few silly mistakes buying cheap PSU's in the past and I would hope this card will work OK under load.

I think you are going a bit overboard on your PSU selection :) 

The HD7950 (I'm assuming this is your card..correct me if I'm wrong) is a VERY power efficient card. This PSU would be MORE than enough for you to run your entire rig with some overclocking headroom :)  (This would be more than enough for an HD7970 incase that's what you meant)

AMD does not specify an HD7960 GPU. What PCIe power connectors are required on the card? Two 75W 6-pin PCIe power connectors OR one 75W 6-pin and one 150W 8-pin PCIe power connector?

The Akasa is not a significant upgrade from a 'cheapo pile of turd.' Where are you shopping? A good quality 500-550W PSU is likely sufficient for your build; AMD specifies a 500W PSU for both the 7950 and 7970 with the only difference being the PCIe power connectors. In the US, a great deal is the Seasonic M12II-520: and in the UK a great deal is the XFX Core 550W:

All u need is 600W PSU. No AKASA. Get something different.

Hi Guys,

Sorry just realised I put 7960 (I was thinking of the Cisco 7960 IP Phone for some reason) - It's a Radeon HD 6970 I am using.

It has 1X 6PIN Connector and X1 8PIN connector.

Also I will be shopping within the UK. Basically I have enough £££ to get this Akasa PSU but if you think there's something better which is more expensive and will hold out for that.

Thank you. RHT's recommendation vice AMD. Nice quick reference for GPUs...I already use them for their PSU DB and will add that for the GPU data.

@ Unixm: A system with a single HD6970 requires a 550W PSU with 34A on the 12V rails and one 75W 6-pin PCIe power connector and one 150W 8-pin PCIe power connector. The XFX Core 550W has 444A on the 12V rail and is electrically sufficent for your build; it also has sufficient PCIe power connectors for your build (one 6-pin and one 6+2 pin PCIe power connectors). At 50 quid it is also less expensive than the Akasa while being a higher quality PSU with a longer warranty; I highly recommend it.
