550W or 750W ... That Is The Question

post #1 of 19
Thread Starter 
I think a PSU in my sig rig is needed as my current PSU is from an eMachine and god knows what it's actually doing to my hardware..

So the two PSUs that I am looking at right now are:

http://www.newegg.ca/Product/Product...82E16817121080
KINGWIN Lazer Platinum Series LZP-550 550W Power Supply

http://www.directcanada.com/products/?sku=13220AC3281
OCZ Fatal1ty Series 750W OCZ750FTY

Both are modular but not fully modular. I hope that as long as I've got a bit of slack on the main power connector, I can take it far enough out of the case to use compressed air on and clean it out when need be.

The Kingwin sounds like it's the best 550W on the market, but I will need more than 550W to go SLI in the future. I am planning a $2000 gaming rig, so SLI may be something to keep in mind (I am still undecided).

Or I could get the OCZ 750W, it has a bronze rating, not platinum, but it's also about half the price and I could invest that in other things.

What do you think? If I want to keep SLI in mind for the future, is a decent 750W the way to go? Or maybe I should get a really good fully modular PSU that is good for both single GPU and dual GPU setups?

Thanks

If you are going to spend 2g's on a rig get at least 750 to future proof. I would look at the seasonic gold 750, one of the corsair ax series or hx series.

Depending on exactly what you'll be heading into the SLI realm with, that Kingwin would serve you very well..

Yeah, you need a 750W or 850W. I would take a look at Seasonic or Corsairs PSUs. Seasonic 750 and 850 are both modular while only the 850s from Corsair are modular.

EDIT: Took another look, I would recommend you buy a 750W and that should do you.

For the cost of the Kingwin you could just about get a corsair 850watt. Id always say get the best psu you can afford.

The Kingwin is a nice PSU and will probably push out at least 700 watts before efficiency really starts dropping. For a similar price though you could pick up a silver-rated 850 watt and be sure that your voltages will stay where they need to be.

Do they ship to BC though?

I am confused.. the Kingwin is a 550W, but it can push out at least 700W? Is this because the efficiency of this PSU is so amazing and if Kingwin labeled it a 700W would it lose it's platinum status?
