Is 750w enough?

[Jordan97]

Starting a new build and just bought a 750w PSU but starting to worry it won't be enough.

Build plans are as follows:

i7 4770k overclocked
4x4GB DDR3 1600MHz
2 SSD's in RAID
A 7200rpm HDD
about 5 120mm fans

The graphics card I haven't decided on, I'd like to be able to game so I'm thinking maybe a GTX980? Although I would like to have the ability to go SLI in the future which is what I am worried about. Will I even need to go SLI with one of these cards?

If you have a quality PSU then you be fine with that system and possible SLI.

It's a Corsair CX750m so it's not super high end but not the cheapest. Do you think it might be better looking for something with a little more head room?

You will be fine with PSU.

Ah thanks that's a good review!

I wouldn't trust it, especially if you plan to SLI or overclock. The Corsair CX are low end units.

Ah conflicting opinions!!!

I think SLI might be pushing it, but the power supply is plenty for a single GPU system.

For comparison, my computer is very similar except with a 290X and I pull around 430W from the wall during gaming in stuff like BF4.

I also think SLI 980 is pushing it with that PSU. It's effectively a 650 watter once temps reach around 40C.

If you are serious about 980 SLI I'd return/exchange the PSU.

 

[Jordan97]

Okay thanks that's what I thought, guess I'd better start looking again then haha

I wouldn't trust it either, it's a very budget PSU for budget builds - nothing I'd be trusting with SLI 980s
