Newer Gold PSU or Older Plat PSU?

[Shd0w2]

Older as in used? or Older as in it was released a longer time ago? If you mean released a longer time ago, grab a Platinum PSU because even if it was released a while ago, it still conforms to the Platinum efficiency spec.

Its basically a series behind, its not used but its a series behind the other one

Depends on the PSUs in question, and more importantly, the price

Its the EVGA 1000W Gold G3 vs the EVGA 1000W P2 the price difference is like 40 bucks

They're both the same quality. I'd go for the efficiency alone at 1kW though

why 1000W??

The P2 is better, but if it's $40 more than the G3, the G3 is really good too.

Why the heck are you getting 1000W? The G3 is an insane work of electrical engineering, and is more than reliable enough for even the most high-end system, but I'm curious why you'd go so overboard with the wattage

 

Future proofing basically. just dont want to have to buy a psu in the next 10 years basically

So your saying for the P2?

Then go for something reasonable. G2, G3, RMx 750. They've all got 10 year warranties IIRC.

What is the price difference?

Computers are using less power, not more. 1000w would be used for three GTX 1080s, not a future GTX xx80. You'll probably need to buy a new PSU in ten years anyways, as computer power connectors probably will have changed.

Price really doesnt matter and i dont know what will be coming out in the next 5 years that will take more power so thats kinda why im getting it.

Get the cheaper one. They are both excellent.

A 7900X and 2 Titan XPs in SLI use 705W

I hate it too.

Between the G3 and P2, I'd take the P2 if you're going for 1000W. 

 

Spoiler

Though, I'd prefer you choose a 750W P2/G3 so that the 20-50% efficiency lines up a little bit better than the 1000W.

So are you saying maybe just get a 850W at Plat or Tita?

Whats wrong with the calculator?

It's a rough estimate, but good enough (uses TDP as a measure instead of actual load, right?). The point stands, it's not going to go above 710W on load anyways

wait for the price of a 1k watt Plat psu i can get the 1k watt g3 should i just get the 1k watt g3?

It's inaccurate and it takes half a brain to realize that a calculator provided by a company that sells power supplies has monetary incentive to exaggerate the power demands of a user's PC. Just look at Guru3D reviews of your hardware for an accurate power draw estimate.

Both are great, get which ever is cheaper (1000W is too much though, unless really worried about fan noise).

Isn't the power supply less efficient when you don't utilize it? I.e have a 1000 W power supply and and don't use more then 300 W it don't reach the gold/platinum efficiency? You should use 700 W and up to peak the performance on a 1000 W Power Supply?

Not at all. 

 

For 80+ White, it's 80% efficiency at 20% load, 50% and 100% load. 

For 80+ Bronze, it's 82, 85, and 82. 

For 80+ Silver, it's 85, 88 and 85

For 80+ Gold, it's 87, 90 and 87

For 80+ Plat, it's 90, 92, and 89. 

And finally, for 80+ Titanium, it's 90 at 10% load, 92 at 20% load, 94 at 50% load, and 90% at 100% load.
