Worth to get 1000W PSU instead of 850W?

[Sikari]

In my country, Corsair RM1000W is only 15€ more expensive than a EVGA Supernova G2 850W. Is It worth to get the 1000W one.

CPU: i7 6700K (Possibly OCing)
GPU: 2-Way SLI Gigabyte GTX 970 @ Stocks
RAM: 2x8GB Corsair Dominator Platinum 3000 Mhz
Mobo: Asus Maximus VIII Hero

 

[Someone Somewhere]

For a single 970? You could get a 550W and be more than fine.

Quality is more important than quantity. I wouldn't put RM on the 'quality' list.

not when the 1000w is worse quality


g2 is top tier


the rm is tier 3, avoid

No, the RM series, isn't really the best quality. The Supernova will be more stable and reliable. Also, its not good to go for a PSU with too much wattage. EVGA Supernova G2 850W is better but you may want a 550 to 650W PSU instead.

there is no downside to having higher wattage psu except the cost of the unit itself

 

[Someone Somewhere]

Reduced efficiency too.

Reduced efficiency too.

he said he is going to overclock, i dont think that would be an issue for him?

also with high quality units, isnt efficiency always good regardless of lowered load?

 

[Someone Somewhere]

No. Typically, efficiency is poor at low loads, increases up to around 50%, then begins decreasing again.

Effeciency also has little to do with quality - you can get very good but inefficient units, and very poor but highly efficient units.

Will be running SLI 970.

@Sikiri, I live in the US. On NewEgg, the price of the platinum efficiency version, EVGA P2 850, just dropped in price with a rebate promotion. You should check the prices of both the EVGA P2 850 and EVGA G2 850 and see what the price difference is in your country. If the difference is no more than $10, I would suggest going for the P2 model.

What units are you basing this info on?

The EVGA G2 750W is 88.5% efficient @ 150w load, thats 2% lower than its max efficient load 300w.

Suppose it depends on how low you class low load.

Unfortunately I live in Finland and newegg doesnt ship there. I guess im fine with the G2?

 

[RobCrezz]

Yeah the G2 is a superb PSU.

 

[rcald2000]

Yes, the G2 would be a fantastic upgrade. Pull the trigger and order it.

Look at the 10% load. 83%.

I'd consider low load to be the idle power usage of the machine attached, which is almost always <100W, and likely <50W.

Will do! Thanks.

My current rig at the moment sucks. Since these are my future parts which I will order... right now Thanks for the help
