JonnyGuru review. As usual, EVGA comes up with the goods. Solid unit, decent price and 650W reasonably as high as you need to go these days.
I do love a modular supply.
Look like a very good PSU, i think i have a EVGA PSU myself, bought it 3 years ago when i upgraded to a i7 core, 650 watts, and at present said PSU is powering a GTX970 and the Oculus rift with no issues today, so yeah, good quality.

To be fair you could probably run a GTX 970 off a couple of D-Cell batteries, those things sip power even when massively clocked.
Can run a 970 off a 500 watt easy
it really is worth replacing that bog standard power supply that came with your case with this if you are upgrading your graphics card.

Even though the power supply does not appear to do much - it will eliminate those random crashes your are experiencing but cannot identify what the cause is.
I have the 650w version of this and whilst even that is overkill for me (and most users), the silent/eco mode is fabulous. TBH, ive no idea if the fan ever comes on but I did test it was working before I installed it. I got it while it was on offer on Amazon back in May 2017.

I find the cables a little stiff for routing tidily but that's a fairly minor problem really and its a damn sight better than cable management with non-modular psu's.

It would be a shame to hide it under a PSU shroud really :-)

It though the rift and sensors might have added some issues to power requirements with four USB 3.0, but no, all chugging along nicely, but i doubt that would be the case with the standard PSU that came with the case all those moons ago, right nasty peice of work that thing was, and in a cool master case as well. lol
Realistically, how much more protection would a gold rated PSU provide over a bronze?
I have had a bronze for nearly two years in this machine and have had no power related crashes; just a few from specific buggy games.

So, can anyone tell me why I should consider going to a gold rated PSU?

The bronze and gold ratings are related to efficiency and nothing else.

OK let me put it another way: What realistic difference am i going to find with a gold rated rather than a bronze rated PSU?

nothing to do with reliability, its power efficiency which also has a knock on effect of reducing temperatures.
although often gold have better rail stability to justify the price but this is not part of the gold rating and sometimes bronze can have better stability than some golds.

lower bills, reduction in psu temperature.

to put it simply the psu takes power from your wall socket.
80+ bronze will take 82-88% of that power and feed it to your machine, the rest is lost, as energy simply can not be made or destroyed its lost through factors like heat.
80+ gold will take 88-92% and lose less through heat.
then there is platinum and titanium but at best titanium only maxes out at approximately 96%, platinum and titanium have a very premium price tag for those lest few saveable percent so you would have to be a well funded enthusiast to bother.



An admission that I simplified and request that people refrain from pointing out I simplified as it was a response to someone who obviously has better things to do with their time than nerd out on PSU information.
the variance percentages per class are based on current load, voltage, and if its redundant or non redundant and classification but I'm not teaching a master class so I kept it simple.

Thank you.
This is precisely the sort of info I was looking for.
This is only a semi-modular PSU, Ebuyer have listed it incorrectly. EVGA Website

quite correct, Its not something that bothers me... as if I wouldn't attach the mobo cable. lol

But since you have pointed it out I will update the description on the deal.
Running a 1080 off a 450w platinum super flower myself. 650w is overkill and then some. Go 550w and platinum IMO

The longer warranty, modularity and lack of c(r)apxon caps of competing products win out over 2% more efficiency imo.
Beware the ides of cheap PSU...

Always go tier 1 or gamble with your entire build

Decent psu for the price. If I hadn't bought a seasonic 750W 80 plus gold PSU last year on Amazon for £80 I'd have jumped at this

lol, I wouldn't say tier 2 is a gamble.
tier 2 is reliable, what you will find in tier 2 is nit picking reasons not to put it in tier 1.
sure 4 and 5 are gambles, and tier 3 means you probably should have spent a little more.

The problem with the list is its not quantified in any way. why is a psu rated higher or lower. if they gave real info on rail voltage stability or mtbf, efficiency variance at 20%/50%/100% load and other data they have or haven't used to quantify then it would be scientific.

the list has been updated by multiple people so now there are many versions, GQ for example has appeared in tier 1 in a few.

when I pick a psu I use the list just for pointers, have a look at prices, then find well written reviews where the reviewer has taken the time to test for stability and performance.

this psu is generally listed as having excellent voltage stability, gold standard with some tests showing almost titanium standard low load efficiency (but dragged down to gold as that's its lowest performance), and good ripple control (although not its strongest point as g2 is slightly better).

one of the main mark down points vs the g2 and gs which are tier 1 is that its only semi modular.modular or semi modular is redundant once its fitted, I have had both and since its the mobo cable that isn't modular and you will need that its not like you aren't going to fit it, it just means ease of fitting which I have never found to be much different.

Now I'm not saying you are wrong, everyone should be wary of the cheap ones, but this one isn't cheap its good value, its also not risky because some unquantified list some person I have never met wrote once.

You do realise in order to gain efficiency you need to use better quality parts?

A platinum PSU will always be better put together

Compare the Superflower Platinum King to the EVGA G2 range and you'll see that the Gold unit wins. It's also cheaper, modular and has 2 extra years of transferable warranty.

I'm not saying platinum units are bad, they certainly aren't in the vast majority of cases but they are not always "better put together" and frequently they are quite pricey.
