Please help chose a PSU

[yanna1]

Hi,

I have been looking around for a new PSU. I have slowly been upgrading things and this is next on my list. I have a budget of around £80GBP. I reckon something 600w + to keep me ahead of any other upgrades later on.

I quite like the EVGA 650W SuperNOVA G3. A wee bit over budget but for the right psu i would do that.

Corsair Carbide 88R Case (Max PSU Lenth 160mm)
Intel i5-6500
MSI B150M Motherboard
2 x 4GB HyperX Black Fury 2133 Ram (Soon to be 16GB)
Asus GTX 1050ti
Seagate 1TB
Samsung 860 500GB SSD
Cooler Master B-Series B500 500w Ver.2 80Plus

Thanks for your help

I know there’s no point arguing with you, that goes no where.

So let’s make your opinions useful to OP.
Using this review as a guide, and considering power supply efficiency an CPU power consumption, OP’s current configuration -i5 + 1050ti - would consume ~110w at load. Devise by 0.6 to find your recommended PSU wattage, 180w.
Now let’s take an i7 OC + GTX 1080ti configuration which could be a possible upgrade. We end up with a ~510w PSU recommendation.
Pretty much inline with my suggestions, knowing there aren’t many good <400w PSUs.

The problem I have is when taking a “calculator” reading, which is already overestimating by ~60+%, then adding another overhead on top of that, or when people are mislead to believe a PSU performing exactly at 50% somehow makes it last a lot longer.

OP, high quality, <£90, fully modular, <150mm depth power supplies include the Seasonic Focus Plus, EVGA G3.
Very good semi modular power supplies also <150mm include the Corsair TX550m and Xilence Performance X.

I've never seen a PSU calculator add 60% to the calculation. I think maybe that's just you making stuff up.


As far as the OQ is concerned, any of these would be excellent.

How could I make up such a specific number? How would that be helpful to anyone?

Here's an example. Outervision estimates 508W power consumption at load. As seen from the Techspot review linked in my previous post, actual power consumption during load is ~310w. The estimation is 64% higher than reality.

The XTR is incompatible with OP's system, the RMx is on the larger side of OP's likings. Reading previous comments can avoid these confusions.

The XTR 650W is compatible with the system.

That TS article was for the reference card at stock speed and a 7700K.

Here are more realistic power consumption numbers just for the GTX 1080Ti, 3rd party cards..


330W plus and 328W respectably OCed. EVGA FTW3 and Asus ROG Strix. (That's just for the GPU alone.)

Intel Core i7-7700K @ 4.9GHz

That's an overclock. The CPU used in the TS review.
An aftermarket 1080ti , uses ~60W more, not 200w. An OC aftermarket 1080ti uses AVG. ~100W more than a stock FE at load.
What is your point? That an overclocked i7 + overclocked 1080ti may require a 650w PSU? That's already been mentioned several times in this thread.

The XTR 650W is compatible with the system.

Because a 170mm PSU can fit in a 160mm max case? Why do you even bother commenting without realizing the situation?

You really don't have a clue what you are talking about.

I am done.

That case will support a longer power supply. I know, I've installed them before. AND, if you want one more than 180mm, which will be a tight fit but can likely be done, you can also do a small amount of modification and move the hard drive cage a little close to the front and fasten it back down with screws, rivets or depending on your skills and whether you're willing to buy another six dollar drive cage, ditch it altogether.

Bottom line though, that case will support up to 170mm PSU, possibly longer, without even removing the drive bays.

Here's one example:

Wow!! Thank you everyone for your helpfull comments. I reckon i will go with the Seasonic Focus Plus 650w as its the same size of psu as i have now. That way i feel confident it should be a straight foward swap. Hopefully no need to move drive bays ect.

I reckon the 650w also as i plan to hold onto this psu for a while so some time down the line i may completely change my build.It will be good to know i have a solid psu that can take these upgrades.

I am new to pc building and i find it very exciting adding fans ect to my build. I do realise that for now its more than what i need but at least this way i will feel confident adding things to my build.

I appreciate everyones help

Thnak you everyone

You will not be unhappy with practically any Seasonic product. Even their OEM style units are very good, for what they are. The Focus and Prime units are really good power supplies. Good luck to you.
