system power on Thermaltake Smart 730 SE

[giusgius]

Hi

 

I have 

 

Z97-PRO / 1070Ti Gaming 8G / 4790 / 24GB Savage 2400 / Hyper M2 x4 with 970 Evo / Smart SE 730

 

Smart Se is bronze certified and it says that peak output capacity is 830 W... and every other PSU says that Peak output is more then Max output capacity...

 

1. I wonder where does 830W output come from ? does it mean the lost heat ro something? 

    I know that if PSU is i.e 730 W , the actual power will be less for the system, less then 730 right but what is peak output then? or how 830?

 

2. does this 730 SE PSU is enough for my system? can I OC (BCLK)

 

I had 750 W GOlD and I could OC RAM and get more OC now on 730 SE PSU I can't do the same OC...

 

Thanks

Peak output capacity is how much power the PSU can supply for a very short amount of time, usually 60 seconds. So you can't draw 830W from it continuously, but it allows for short peaks up to 830W.

I don't know what you mean in the first part of the sentence. If the PSU is rated for continuous power at 730W, then it can provide 730W for the system, continuously.

Peak output is the 830W number explained above.

 

 

Getting this Thermaltake Smart SE 730W was a big mistake. It cannot hold stable voltages and cannot handle high transient loads generated by expensive graphics cards like GTX1070Ti. It's very inappropriate for your system and you should replace it with a good 450W unit - one with DC-DC converters for voltage stability and one that won't turn off from tripping over a high voltage drop from the fast graphics card.

Your problems with overclocking are probably caused by low quality and instability of this PSU.

Does it have any purpose or it is just as it is from the factory?

I mean that as I know PSUs rated at certain Wattage, they actually provide less Watts, i.e 730 SE = 700 W REAL POWER, or kinda like this... I'm not sure.

I'm going to buy Thermaltake Toughpower Grand RGB 750W 80+ Gold on Black Friday, this will be good right, good quality I think? Thanks for help !

The purpose is like I said, to allow for short peaks over the maximum continuous power output.

No, that's not true. If a PSU is rated for X continuous watts, then it can provide X watts to the system. Words have meaning.

Of course brands which make PSUs for $10 will lie about how much power their units can actually provide.

 

In addition to this limit, every PSU also has a limit to how much power it can output from a particular voltage. You may have a PSU that is rated for 750W total power continuously, but its main 12V rail may be limited to 650W. The 12V voltage is used by most components in a computer, including the processor and graphics card.

Nope, that's a waste of your money since your entire PC consumes about 220-250W under heavy load. If it costs like $50, then it's a better choice.
