I need some help here, well, my brother needs some help. He's bought a GTX 480 but needs to upgrade the PSU as his current one is old and doesn't have the required power cables for the card. I was thinking a 750W PSU should suffice? But because he doesn't have much money to spend and I don't want him to get a cheap PSU which is likely to break, what would you recommend?

Is 750w an overkill for a GTX 480, would a 650W PSU do the job instead? I know Corsair produce solid power supplies based on experience, but I've also seen one of OCZ's 750W (OCZ-ZS750W-UK) PSUs for £60 (on a competitor's site) and was wondering if that'd do the job?

Any suggestions?

EDIT:
How's OCZ's reputation with regards to the quality and lifetime of their PSUs?

500w is fine for a single gpu setup
750w for a dual gpu setup

edit: actually for a 480 i'd say 600w min, its a power hog

You will be fine with 650w but I managed to get 615w from the mains with my old 920 system and 480 GTX running Prime and Furmark, in games you will not see this though.

So would you say that something with a higher wattage than 650W would be more than is required, but would also give a little more breathing space?

Just been thinking if your running a SB setup or IB then you be fine with 650w.

yea the gtx 480 part didnt ring any bells until i posted ;p
anyway i'd say any of these psu should be fine:


YOUR BASKET
1 x PC Power & Cooling Silencer Mk III Series 600W High Performance Modular Power Supply - White £74.99
1 x Antec High Current Gamer 620W '80 Plus Bronze' Power Supply £69.98
1 x OCZ ZS Series 650W '80 Plus Bronze' Power Supply £56.99
Total : £214.56 (includes shipping : £10.50).

Agree with the PSU choices.
 
The CPU is a Q... something (so a quad core), running at 2.4Ghz as stock. I can find out the exact model if necessary.

As for the PSU choices, I've actually found the OCZ one at 750W (OCZ-ZS750W-UK), No competitor hinting please. I'm 95% sure that it is the same model, the only difference being the wattage. So for an increase of £4 for 100 more watts, I think it'd be a wise decision if I say so myself.

So, should I go ahead and order the 750w OCZ ZS Series PSU? I'm presuming they aren't a 'bad' brand?

ah, but do you have to pay for postage elsewhere? cuz you dont at ocuk
dont forget the postage costs!

The postage is free at the other place, but it can take up to one week. But when I've ordered before, it's never taken that long. Otherwise, I'd have to pay if I wanted to guarantee a quicker delivery.
 
ah, i guess it depends if there's someone at home to receive the parcel or not.
if there's no one at home and you'd have to take time off, the non-guaranteed delivery would suck ;p

I'm pretty sure I will or somebody else will be in to receive it. :)
Also, I have another question; when reading the description of a Corsair PSU, I noticed it said: "It supports the latest ATX12V v2.3 standard and is backward compatible with ATX12V 2.2 and ATX12V 2.01 systems". If I'm honest, I never knew there were such versions of ATX12V, I thought ATX12V was ATX12V and that was it. The CPU socket is LGA775, but I'm presuming the OCZ PSU should be fine? The motherboard has a 24 pin power connector, and a 4 pin connector near the PSU.
