Recommend a PSU for £90 or under?

post #1 of 27
Thread Starter 
Hi all,

The last part of my system is a PSU. I had an XFX XTR 650W PSU on order from Dabs, but they're taking forever to get one in stock so I'm changing plans.

This is my system.

I have read I don't need more than a GOOD 650W PSU for the GPU (even though it states minimum requirements is 750W). I was looking at the EVGA NEX650G Gold but this thread warns me off it.

What would you guys recommend? I am looking for something that will last and power my system. I am not planning on doing much, if any, overclocking (my motherboard won't allow the CPU to oc anyway).

Thanks...

The 750W minimum is for peak-rated PSUs. The typical 750W peak-rated PSU would have a +12V capacity of about 540W (which is 45A on 12V power). However, you wouldn't even need that much. Check this out:

 

http://www.guru3d.com/articles_pages/radeon_r9_290_review_benchmarks,10.html

 

With one R9 290 under full load in their system, their PSU pulled 372W from the wall outlet. Their CPU was idling, so I have to add up to 85W for your CPU under full load. This makes the PSU pulling 457W from the wall outlet (while the 290 and 4670 are under full load simultaneously). This means that if the PSU is 90% efficient while pulling 457W from the wall outlet, then the computer is pulling 411W from the PSU. Your power consumption while gaming will be even lower, never exceeding about 375W.

 

Therefore you could power this with a good 450-550W PSU very easily.

 

The best one that I can recommend to you for under £90 is the 550W Antec TruePower Classic:

 

http://uk.pcpartpicker.com/part/antec-power-supply-tp550c

 

I guarantee you that this will have all the power that this build will ever need. It's also a high-quality unit as well.

Thanks for this. Would others agree with the 550W assessment?

I kind of feel I need 650W to be 'safe' and to further future-proof any upgrades or mild OC-ing I might make.

Also, I was hoping for modular, but I guess it's not 100% necessary.

Any other recommendations?

I just explained to you that your power consumption while gaming will never exceed 400W (approximately 375W). The only upgrades that would require a 'bigger' PSU would be a like adding a 2nd video card.

 

This is enough power unless you overvolt the video card.

 

If you want modular, then you're gonna have to pay more than £90.

 

Here are 3 others, but they are unnecessary overkill here (try to ignore AMD's silly "750W" PSU recommendation...):

 

 

These would only be a worthwhile investment if you plan on having two mid to high-end video cards. Or, if you plan on overclocking and overvolting the 290. Out of these 3, the HALE90 blows them away (and it also has a beautiful white finish).

Thank you for this. So on 550W I could oc the GPU (but not overvolt it)? The GPU I have is already OC'd, I think, by Powercolor, the manufacturer. Is this an issue?

How about the same XFS PSU but in the 550W version? Fully modular, Gold, good price.

If you're going to be doing your own sleeving, then yeah that would be a good choice. Otherwise, fully modular PSUs are really kind of gimmicky. I mean, does the ATX12V and EPS12V really need to be modular?

Thanks. Have found the XFX TS 650 W for £60 which looks like a really good deal. Haven't found the 550W version much cheaper (£57 as opposed to the £60 for the 650W). Any thoughts on this PSU?

Thanks again for your help.

To be honest, I don't know much about it at all except that it's supposed to be based on the SeaSonic G:

I don't know if this means the S12G, or the G Series. Either way, if that's true, then it's a pretty solid PSU. Of course, you can also ask shilka.

S12G is a non modular G and the XTR is a fully modular G

XFX TS is a S12G so all 4 are G models

The new Antec Edge is probably a fully modular G
