Hey guys, I need to buy a power supply and have a budget of £140.00 excluding VAT. It needs to be 1000w and SLi ready. Can anyone please advise me on the best PSU I can get on my budget, thanks.
 
I know a lot will say dont bother with the 1000 but its better to be sure, everyone seems to like the Corsair PSUs but personally I have an OCZ and it works a treat

The reviews say otherwise:

Our test system contains a Core 2 Duo X6800 Extreme Processor, the nForce 680i mainboard, a passive water-cooling solution on the CPU, DVD-rom and a WD Raptor drive. The results:

* PC in Idle = 197 Watt
* PC 100% usage (wattage gaming Peak) = 530 Watt (SLI)
* PC 100% usage (wattage gaming Peak) = 749 Watt (3-way SLI)

I would recommend at least a 800W PSU for 280 SLI, you don't want to run PSUs at anywhere near 100%, they also degrade with age so in couple of years you won't likely get the rated power. Personally I would aim for peak power to be no more that 70% of the rated power of the PSU.
 
i was looking for 1000w psu myself lately... and I narrowed it down to 2 options

1.Corsair 1000w (has 2 separate 500w transducers)

2.Antec TruePower (has the less signal noise out there)

the second link is a roundup of various 1000w psu,, have a good read ;)

3.Thermaltake makes pretty solid power supply units as well
 
the thing is you cant jsut get a PSU based on wattage, as it lets say a system with a GTX280 draws 400W. you get a 500W cheapy PSU thinking its enough, but it wont run. you need to be looking at Amps aswell, most importantly the 12V rail(s).

so just becuase a system draw X amount, doesnt mean youll need a Y ammount watt PSU, there are other factors.
 
Slight off topic but you just wasted a lot of money on GT280 and you want to waste another a lot of money on second one.

You could get quad crossfire 4870 for less than this lol.... and you will get probably about 200% the performance :D.

And you mentioned another 280 for tri-sli ....

Am I the only guy having feeling that this guy wants to play Crysis at max settings only and doesnt care about anything else ? ;-).

Thermaltake PSU.
 
BTW if 2xGTX280 is going to consume 530W then you need to ensure your PSU can deliver a minimum of 44A total across the 12V rails preferably with some headroom. I personally like the Coolermaster range (and bought the 850W myself). The PC Power And Cooling 1000W unit also looks great as it has a single huge 72A 12V rail - more than enough for any system.
