What's the rest of your build, a safe bet for power draw on the 7970 is about 300 under load... But I doubt that your 12 v line can handle that.


Bare in mind he's looking at the 7950 but according to this Hardocp full load with an overclocked card is 425w

So does that mean that I will okay with my current 460w psu and a PowerColor PCS+ AX7950 Radeon HD 7950 3GB video card? Yes or no?
Thanks.

Without posting the exact model of the PSU it's hard to know, as Sora_Anbu stated if your current PSUs 12v rail can't handle that amount then no, there's more to consider than just the advertised wattage of a unit.
FWIW AMD recommend "500W (or greater) power supply with two 75W 6-pin PCI Express power connectors"
Also we'd need to know whats in the rest of your system as pointed out by Sora

Also any reason in particular for selecting a Powecolor card? or is it just price?

I will try to the info off the psu that I have now to see if it is enough to run the new video card.

Then I guess that I should get another psu. Is the one in the link below good enough?

No, Coolmax PSU's are terrible.
"Tier five - Replace immediately. These units are NOT recommended for any system, no matter the purpose. Reference to higher tiered models for a better and potentially money-saving unit


A-TOP technology
Apevia
Apex (SUPERCASE/ALLIED)
Artic / Ace (They're the same company)
Aspire (Turbocase)
ATADC
Athena Power
ATRIX
Broadway Com Corp
CIT

Cooler Master
eXtreme series
Elite series

Coolmax
Deer
Diablotek
Dynapower

etc..."

The list in its entirety including all tiers can be viewed here:

Okay, the Dell psu that I have the model number is D460AD-00
I hope that is enough to run the Radeon HD 7950 card, because I really can't afford to get another psu.

no, be safe and get a quality psu

edit: if you do not get a better psu...you might have to buy another 7950 and another psu and possibly other computer components

The 460W PSU found in a lot of Dell computers is fine for a Radeon 7950. It's not crap by any stretch of the imagination.
