Coolermaster Elite Power 500w help.

by AlexEvans00122 / March 27, 2013 8:42 AM PDT

I have a quick question about this power supply. I have just ordered an i5 3570 non k along with other gaming basics 8gb of ram etc. I recently brought a coolermaster elite 430 with a elite power 500w power supply.
I am planning on getting either a gtx 660 non ti, a 650 ti boost when that is out, or a 2gb 7770 depending on how far I will be able to stretch my budget. My question is will this power supply be able to run these graphics cards? Or will I have to send this back and get a different one? Later on I will crossfire/SLI and will change the power supply then.

Here's how I figure this out.
by R. Proffitt Forum moderator / March 27, 2013 9:15 AM PDT

I find the usual reviews that tell me what said video cards draw in idle and under load. That's where I look at the power supply and check that any of the rails I want to see no more than 50% of the capacity in use. Sure you can probably push that up to 75 or 80% but as we do that we are eating into the lifespan of the PSU.

Not only that, the usual Amperes and total Watts are only when new and even then tend to be overstated.

-> But those cards are all in the same tier range so I'd not change the card once I got that.,3107-7.html pegs the 7770 lower in the ranking so I'd use this link to find the best for the money.

12v1 and 12v2?
by AlexEvans00122 / March 27, 2013 6:51 PM PDT

The Amps on both of the 12v rails is 20 and I am not sure how to work out if this will support the cards. The wattage should be fine though then.

Yes the psu should work.......but.but.but.

With that split rail design you going to be pushing rail #1 a little.

That psu with its 70% efficiency is not designed for gaming.
If you push that thing for long periods of's going to get hot.

Do you think that I should pay the extra £25 plus shipping to get the same case and an a corsair cx500w instead? This would decrease my budget for a graphics card however.

If your going to game your going to be pulling serious power for long periods of time.

You need a psu that can handle that.

We all have a budget to work in.......the psu is not the area to save bucks.
You don't want to see the results when an over worked psu goes wonky.

Ok, thanks for your help guys. I will see what i can do and try to get the same case but with a cx500 from corsair instead. Might have to get the 7770 instead but I will probably be better for it. I don't want to dammage any components.

Thanks again, Alex

Imagine if this was a Single 40A rail.

This is why we check Amperes. Your setup is above the 50% mark so it's not going to last more than a few years at best.

There's a reason why you see many advise a single rail PSU.
