Need some help with PSU choice !

post #1 of 26
Thread Starter 
Hi there. I'm a bit confused about my PSU .. I really don't know what wattage to choose for my system. I do plan to OC my GPU and CPU and in the near future to add one more GPU for crossfire. So if anybody can advise me with my PSU choice that will be great . here are my specs : http://uk.pcpartpicker.com/p/Bv9y7P

I forget to say that I'm on a budget ( 80£ ) and I live in UK .
Thanks

With overclocks your system will use 500w at most, and that's with heavy clocking.

I recommend a 550w unit. Where are you buying from?


Maybe something like this:

Hi . Thanks for your reply . Well I'm using all the time Amazon to buy things , mostly bicouse they have a fast&free delivery.. But I'm really confused about this PSU thing .. I was post on many sites and I get a lot of different opinions.. Some people saying that I need a minimum 750w without a second GPU , and with a second GPU I will need 1000w... And I really don't know what wattage I need . That's why I try to get as many recommend opinions as I can .. And after I will make a decision . I do know that my system draws from the wall 452W ( pcpart picker shows that ) ... So how many watts I need ? Thanks

You need a 550w unit.

You dont need more then 550 watts unless you are going to volt mod the BIOS on your 280x card.
Anyone that tell you that you need more dont know jack what they are talking about or they are trolling you.

Yes 550 watts is enough you dont need more unless you are going to add more video cards or volt mod the BIOS on the one you have.

Yes, 550w is all you need with heavy clocks too.

Maybe shilka can look at amazon.co.uk for a nice 550w unit for you to purchase.

Scan has the Cooler Master V550S for less then £60 and that is pretty much the best mid range option right now.
Cooler Master VS Series 550W
