Zootitan-650 any good?

[chavo]

Hi, quick one....
I have
I7 920
Asus p6t6 ws revolution x58
12 gb corsair tripple chan
1x120 gb Ssd

I have just bought an MSI GTX 680 2gb power edition.

I have a Zoostorm Titan 650w PSU. Now I don't know much about this PSU as it was second hand, looking at the power connectors on the PSU it has 2x 6 pin and another 4 pin (3x 4 pin sockets in total?) which is a bit confusing!

Can anyone tell me:
Is this power supply good enough for the system
Does it have the right connectors for this gpu?

Much appreciate any help.

Without further knowledge I wouldn't go near it.

Yes.

Thanks, could you make a sub£60 recommendation?

Hi,

I have an issue, I just bought this PSU and it has arrived. After looking at some online PSU calculators they all say that I should be using 600w minimum.

Can anyone set my mind at rest please?

that's it.

Never look at online PSU calculators.

lol, ok. So 550 will be enough with a little head room for any additional devices or mild overclocking?

The only way to absoloutely certain is to use a at the wall power meter. Remember your PSU is only about 85% odd (not sure exact figure) so you can times the wattage read off the meter by 0.85 or wattever (clever eh?) to see how much your PSU is delivering. I imagine it would be fine and would be more than happy; check 680 reviews with similar rigs for wattage and check the numbers they are reading bearing in mind different reviewers will use different measurement methods.

The great thing with a good PSU you can be confident it will supply what it says.

I would expect bags of headroom, but as mentioned, you can only be sure by checking real draw for your exact system.

Oh no! I just got all the kit and the graphics card has 2 8 pin connectors, the psu has 1 6 pin and 1 6+2 pin. I'm 2 pins short what's the options?

That's annoying, we spec'd for a 6+8. You could return the PSU under DSR and get the next one up (650W) as that has two 6+2s. Or you could use the adaptor that was hopefully supplied with the graphics card to create an 8pin PCI-E from two molex connectors (or a single 6pin). Or you could return the GPU under DSR and get one that has 6+8 pins.

I wonder if it's possible to run with a 6pin plugged in in place of the 8pin? I've never tried.

Sorry if I got it wrong

In hindsight I could say that you could have done some research on the card that chavo is using, however I can not find an "MSI GTX 680 2gb power edition" on MSI's global website. The MSI N680GTX Lightning seems to be the only GTX 680 from MSI that I can find with two 8pin PCIe connectors.

I think it might be possible with some cards to use a 6pin rather than an 8pin. Although there may be adverse side effects once you get to the power levels where two 8pins are necessary.

If you do return the XFX and get something else then I personally would go for either of these:
Seasonic G-450 (£65 @ AriaPC / OCUK)
http://skinflint.co.uk/sea-sonic-g-s...m-a830685.html
A good choice, even if it is ~£5 over your budget.

Fractal Design Tesla R2 500W (£60 @ CCL Online / Dabs / Ebuyer)
http://skinflint.co.uk/fractal-desig...w-a815546.html

There probably are other units cheaper than these with two 8pin PCIe connectors, but I feel like these are a step above those units in terms of performance and quality and worth the extra cost.

BTW all the XFX 650W units have four PCIe connectors.
