Voltage standards

post #1 of 7
Thread Starter 
Hello. I am looking at buying the power supply I have chosen for my sig rig, namely the GX 650W by Cooler Master. I already have all the other components except CPU, GPU and PSU but I am firm on my choice for CPU and GPU.

First off, I'd like to ask this. I am looking to order from Amazon.co.uk, and I can't help but notice that the product number of the PSU there has a "UK" suffix (whereas on Amazon.com the same PSU has "US" and on Amazon.de it's "EU"). Since I live in Bulgaria, i.e. EU, am I going to need the version that's on the German site, or I can problemlessly order the one at the UK site?

My second question is: I am fairly certain that this is a good PSU to go with. Yet I have an alternative - the OCZ ModXStream 600W modular PSU. What do you think I should get for my rig?

Thanks in advance

Don't get the Cooler Master GX 650, it's crap.
The ModXStream 600W would be significantly better.
You don't need to worry about the UK or EU or US suffixes however. Those PSUs have active PFC so they can work pretty much anywhere in the world, the only thing that varies is the cord running from the wall to the PSU.

If your planned setup is what's in your sig, you could easily power that with something cheaper, such as an XFX 450W.

Oh, I get it now. The difference is the power cord that's included, right?

Really? I am going for a 600W+ in order to have a nice headroom for future upgrades, like some CPU overclock, maybe SLI, things like that.

SLI GTX 460 (though in the future, why not a single 28nm GPU?) with your i5-2500k would easily run on 600W with overclocks. The OCZ ModXStream Pro is significantly better, and there's plenty out there that's better than the OCZ as well.

The problem is with the GX650 in particular, which starts to go out of spec around 500W and is overall mediocre at best otherwise.

Yes, maybe an all new single GPU later. OCZ's price is about as high as I could go in terms of price for the PSU. That being a factor, is there anything better for that cash that you could recommend?

600-650W is reasonable if you will add a second video card, but the Cooler Master GX 650 can't deliver more than 450W safely.
I would suggest you refer to the list of recommended PSUs (sticky topic) in your desired wattage range, you're sure to find something decent.
Personally I would recommend this one:

I'm not sure how shipping is from scan, but if you need something a little cheaper than that, Corsair GS600 (£53.94):
http://www.scan.co.uk/products/600w-...ed-48a-plus12v

It's a step below the XFX unit above (which is the same internally as the Corsair TX650 V2), but it's still good.
