ive noticed that the OCZ modstream 450w and 520w mention peak loads of 550w and 620w. what does that mean. just wanting to know before i buy one thing and find out that the other is better!

read a few posts and people tend to/have been reccomended to go for a bigger psu if using a 7900/7950 card, i think ill got for the OCZ 520w to be on the safe side

if there is a better psu for the same money as the ocz then someone please say. i will be ordering at 9:30 tonight

The OCZ will be fine. Also 400w will be fine but go for something abit better ike the 520w for future upgradeability.

Since its 9:28, i've got two minutes to explain that.

Peak power is the power it can deliver short term, perhaps for 30 seconds before it would shut off. So if for example you have lots of harddisks which draw a lot of power when they spin up it could cope with them all spinning up at startup even if that caused more power draw than its maximum.

For the extreme power supply calculator, do you select 1 pci-e x16 card even if you've already picked a graphics card from the list?

Ive just bought the 520watt one of those PSU to power my 7900GTO as this cheapo 500watt one doesnt seem up to, but this OCZ one does 28amps on the +12v so that should be enough for it.....hopefully
