Advice please on new PSU for new PCI-E system

Thank you; yes, I did look at that list, but unfortunately (perhaps because they're good!), most of these looked out of stock at places I looked.

The OCZ 600W one looked good for what I wanted; I've found it at £81.50:

Would that be suitable?

(Note that I'm assuming that it says SLI-Ready just because it's got a stamp of approval, not that there's anything in it which would cause problems with an ATI system?)

Thank you!

600W OCZ? I just wonder why

I've run 3,0 @ 3,50 GHz prescott rev D (really hot) along with unlocked GF6800, 4 sticks of DDR1, 2 hard drives, 2 optical drives, sb live and some fans on the cheapest 300W PSU for almost a year, until I built a new PC

I guess that I've been looking to buy myself some time on this new PSU as well as satisfying what I need today. The question is whether the sort of kit I'll be looking to upgrade to in 2 years (for example) would be satisfied with this PSU or whether it'll likely need a 2KW model!
I suspect the latter, so maybe it's not worth investing money now to help myself along in a couple of years; perhaps incorrectly.

What sort of wattage would you say would be needed? I understand that the main things to ensure is the total amps to the +12v rails and that it's a stable PSU, but aren't sure after that.


Putting my new system characteristics into the Power Supply Calculator, I found that it thought I would need 277W for my requirements. Even if I went SLI / Crossfire in the future, I'd need around 344W, so it would seem that a 500 or even 400W would do enough for me; correct?

I like the idea of a modular PSU to reduce the mess in my case.

How about the Enermax 400W? Seems like it would be good enough, and it's only £54 (with P&P):

Or maybe it's worth an extra £11 for the Antec 500W model (price £65 with P&P). It's not a great deal more cash, but would I notice the difference?

Or the same price as the Antec model, there's the Zalman model 460W:

Choices, choices!

I don't know about that... my Seasonic S-12 550W w/ 41A is SLI certified but I wouldn't dare fire it up with X1900XTX's in crossfire.

I've now decided on what I'm going to buy for my new build (see my posting on the homebuilt board here).

I would value people's opinion from this forum into that thread please, particularly on the subject of the PSU power.

Thank you!
