Need PSU advice!

[JonnyKennedy]

I have a question.

A Dutch site called Tweakers said you need 450W for the build what I want, but is this a little bit to low?

Here is my (future) specs:

PCPartPicker said 345W, but is 450W to low? Should I go for 520W/550W?

 

Please help me!

Go with a 550/600 watt for OCing

Go with a 550/600 watt for OCing

Do you mean only CPU or CPU + GPU?

CPU+GPU, although getting 650 wouldn't be bad. I'd get a Cooler Master 650W (I think it's V650, but that may be corsair)

[N4dez]

450W would be enough, but that psu would be under load a lot. causing shorter lifespan, higher heat, and sometimes rippling voltages.

 

I would get a 650w for this build, should be a bit of headroom for overclocking and just overall use.

I didn't know it. Thanks

As a rule of thumb only use about 40-65% of up you psu at a load

By gaming (load) or by starting (idle)?

gaming load. That is the advertised W on the component

Using a system with an i7-3960X, PC Perspective testing methodology had seen a power draw up to 288wAC for the entire system.

 

http://www.anandtech.com/show/8568/the-geforce-gtx-970-review-feat-evga/15

Using a system with an i7-4960X @ 4.2GHz, Anandtech had seen a power draw of 300wAC for the entire system during Crysis 3.

 

Review specifically on the 970 Strix: http://www.hardwarecanucks.com/forum/hardware-canucks-reviews/67488-asus-gtx-970-strix-oc-review-9.html

Using a system with an Intel i7 4930K @ 4.7GHz, Hardwarecanuck has had see a power draw of 311wAC for the entire system.

 

Due to the inefficiency of the PSU as well as the SB-E / IB-E processor being of a higher power draw, the actual DC figures that the PSU is supplying would be lowered.

 

The Seasonic G / S12G 450w is a very good quality PSU that is fully capable of powering that system. If you want to invest more on a larger wattage PSU, that is up to you; however, don't feel that you are required to do so. Going from a Seasonic G 450w to an Seasonic M12II 520w, for example, is actually a downgrade.

But it's not if I play a game and the PC shut down because to high Wattage? Or light overclock to CPU or GPU (I'm new at overclocking, I want some time overclock this PC light how to learn overclocking. I don't overclocking to 4.9ghz or something).

Having too much wattage isn't bad. If your computer needs 250wDC from the power supply, it will draw 250w regardless if it is a 450w or a 1000w. Of course, by getting a higher wattage unit, it may impact the efficiency of the unit, where it may have an impact on your electricity bill and the amount of heat it is outputting. Of course, after 20% load, the difference of efficiency between loads is rather small so you don't have to worry about it too much.

 

Anyways, the Seasonic G / S12G 450w can power your system with OCs. But like I have said, if you want to get a higher wattage unit, a 550w unit isn't unreasonable.

The Seasonic G 450w is ~84€ : http://tweakers.net/pricewatch/317760/seasonic-g-series-450-watt.html

You can get the Antec Edge 550w PSU for ~88€ :http://tweakers.net/pricewatch/413709/antec-edge-550w.html

 

The Antec Edge is the same PSU as the Seasonic G internally but offer full modularity, a FDB fan, and a higher output. I would actually go with that unit.

It's intresting, thanks!
