[SOLVED] PSU

[Elixs]

Well, I want to buy an Intel Core i7-8700, Aorus Z370 Gaming 7 and 16gb of Ram, I currently have an Gigabyte Windforce RTX 2070 and a PSU of 600W from EVGA 80+ Bronze, I don't want to have to change the PSU too, will it work?

Add up the power requirements (wattages) of all installed components using the high value of any wattage ranges for any given component.

Likewise use two or three of the online power calculators that are available.

Work out the "worse case" high value wattage total (all components) that the installed PSU will need to support. Then look for a PSU that is rated for that total plus about 25% more.

Key is to determine the margin that will exist between component load wattage and what the PSU is capable of providing. 600W may be enough - no way to know at this time.

And the make and model of the installed PSU is important. May be rated for some voltage range but can only support higher wattages under ideal circumstances. Not under continual high power demand...

I did use two PSU Calculator, this is the result of one of them.

For the most part I would ignore the "payback" and efficiency results. Likely a matter of pennies overall.

You want a good quality, well-rated PSU that will provide at least 650 watts.

Next step is to read some PSU product reviews via this Forum and other objective websites. Plus PSU reviews by verified purchasers.

Also go to the manufacturer's websites to read PSU manuals, peruse the FAQs, and any forums that the manufacturer provides. Look for what is said as well as what is not said.

The PSU is very important. That one component can make, break, or destroy a system in part or in whole.

A failure in any other component will simply make the computer stop working - unlikely to take anything else physically with it. Unless that component starts a real fire.

For an average pc using a RTX2070, it's recommended to use a decent 500w psu.

The important value there isn't the 500w but the word decent. (there literally are NO decent or better 500w psus). What you have is an Evga 600B. By number alone, it's technically plenty of wattage, could even handle some cpu OC. However, it's an Evga 500/600B. There's only 2 psus in Evga's entire lineup that are worse. The 500/600N and the 80+ 500/600W.

Even though the outside says 600w, treat that psu as a 500w when considering any OC and err on the side of caution. It barely ranks as decent so do not expect it to bahave any better.

The problem with online calculators is in their recommendations. The 650w BQ isn't all that much better than the 600B in terms of quality outputs and protections. You'd be far better off with an Evga 550w G2 if sticking with Evga.

You are looking at spending $1000 or so on pc equipment. $60-$70 more for a quality psu with the full range of protective circuitry and good, stable outputs that comes with a 7+yr warranty is extremely cheap insurance.

So I will not have any problem with the EVGA 600B? Because I’m from a Third World Country and I’m literally not eating at school (My father doesn’t want to buy me PC parts xdd) to buy this 8 generation Intel Combo LOL. And I don’t want to have to buy a new PSU too Lmao.

I too would say change the PSU for a 'better' one or as Karadjgne said 'decent' one.

Performance and longevity of all components basically depends on the performance, durability of protective features of the PSU.

It's not advisable to, as said, gamble the life of the components of a $1000 rig on a mediocre PSU which has (assuming a few years old) lost its nominal output to some extent and as said might be better described as a mediocre 500W unit now.

Save some more and sell the PSU you already have and get a better one.

Also you can not really overclock the non-K i7-8700 so don't really need the Z370 chipset and can get a H370 board. Mind you even usually even cheaper Z370s have beter VRM and cooling compared to H370s. But maybe you can save some more by getting a slightly cheaper board, that is a H370 one.

I’ll keep that in mind, and I’ll save a few more money to buy a new PSU. Thanks to all of you.

Will the I7 8700 work with an Asus Prime H310M-D?

Yes it does according to the ASUS website here.

Although that is a H310 and it only has 2 RAM slots. You said you plan to buy 16GB of RAM, make sure it's two 8GB modules and are supported by the board. You can check for RAM on same link/page.

It says "DDR4 2666MHz and higher memory modules will run at max. 2666MHz on Intel® 8th Gen. 6-core or higher processors". Keep that in mind too if you want to get that board.

I know you're on a budget but I'd get a H370 board if possible. They're a bit more expensive but generally higher chipset boards have better SMD components.

Thanks. But I just decide it to go for the i7 7700 because I have a i5 7400 right now. I’m only changing the Proccessor because the price of the 8th gen combo is now 1.000.000 GS (like 90$) higher. Now it’s 4.600.000 Gs and I’ definitelly not buying that. Maybe in a Future I’ll buy that combo. Anyway, thanks a lot to all of you.
