Power Supply

[AYDANN6ix9ine]

Which would be the better option? A Cooler Master MasterWatt 650W 80+ Bronze Semi-Modular PSU or a Corsair CX650M 80+ Bronze Semi-Modular PSU? The Cooler Master PSU is $15 cheaper but I know Corsair is one of the best brands for power supplies. So what would be better price-to-performance?

Either would be fine, though if you need 650W you should probably be looking at better quality units.

What system are you powering?

[AYDANN6ix9ine]

Should I get a Corsair CX550M 80+ Bronze Semi-Modular or the CoolerMaster one I mentioned earlier. Even if it is 100 watts less, should I take it?

Would 550W be enough. Kind of on a tight budget.

Will use <300W. Go with the 550W of either the MasterWatt or CX/CXM.

[AYDANN6ix9ine]

Thanks! Also, do you think this PSU will suffice and still power 550 watts for a few years, maybe 2 or 3?

[AYDANN6ix9ine]

All the calculators are saying about 540w-560w. Are these calculators trustable or do they often overestimate?

[AYDANN6ix9ine]

So I'm planning to get a Corsair CX550M 80+Bronze 550W Semi-Modular PSU for my first build (OC'ed Ryzen 5 2600X and OC'ed EVGA GeForce GTX 970 SC GAMING ACX 2.0). I was wondering because 550W is just over the wattage for this certain build. How long will the Power Supply last? I would expect it to have good life expectancy because it is from a brand like Corsair but I'm not exactly sure. I plan to keep this build for a couple of years, probably 3.

Yes, most of them overestimate by a bit. The CX550M is good enough for the next few years for single GPU uses although I'm not sure how it will fare in SLI. But anyway for reference, EVGA's GTX 1080 SC draws about 450 watts, so really not many people need 650W power supplies.

[AYDANN6ix9ine]

Okay, thanks. I'm pretty young, not teen, so I probably don't got that $$$ to try SLI.

[Crunchy Dragon]

That's perfect.

 

I run a CX550M with an overclocked Ryzen 5 1600 and an overclocked GTX 780, haven't had any problems with it so far.

No, it does not. You're not even close. It draws less than half that.

Oops, I meant to say it draws 450 watts in SLI. 

 

but I guess it does 400
