Powersupply questions

post #1 of 17
Thread Starter 
Hi everyone. Thanks for taking the time to read this!

I have a couple of questions if you don't mind.

I would like to know if these PSU's will be able to handle these systems.

The first one is an i5-750 @ stock settings, 6 gigs DDR3 ram, two HDD's, and a GTX 470 @ stock settings with this power supply.

The second rig is an i5-2500k Sandy Bridge at stock settings, 8 gigs DDR3 ram, an SSD, two HDD's, and SLI 570's @ stock settings with this power supply.

Would it be cutting it too close or are they both fine?

Thank you very much.

First one seems alright. You might want to consider getting an 850W for the 2nd. It should be fine on the 750W though.

First rig is fine.

The second, if you wanted to overclock, I think you will be pushing it.

Wow quick replies, thanks so much! So for the second rig what about this one? Is this a good 850 watt? For the price it would be a steal.

Both are good. 750W is okay for a Core i5 2500K and two GeForce GTX 570s at stock. The original Corsair TX has been replaced though.

Oh I saw that. It's just that I already have this PSU and figured I could save some money. So in the end I should just get a 850 watt? That Raidmax was a good price.

Oh, if you already have that one, then that's different. Use it. It'll suffice.

That Raidmax 850W unit is okay considering it's Raidmax, considering they are usually garbage. I think it's the same as an Ultra X4 850W, but it's not worth paying for over the Corsair you already have.

The GTX 570 is rated at 243W TDP, thats 486W total and that 2500K+mobo wont come anywhere near 250W. You'd be fine with 750W for that second rig.

I would go for a 750 watt corsair over an 850 watt raidmax anyday. The corsair is more reliable and could probably, dont quote me on this, push out just as much wattage believe it or not.
