PSU on way out? If so which one to replace it with?

[Blackhorse]

My PSU has done well to be fair and is 8 years old (Be Quiet P9 850w Gold, Modular)
Its done it for a while, months in fact so I'm a little reserved to just whip it out and change whilst it in theory works

The problem been its making a very very slight crackling noise, (nothing that scares me, possibly that resembles some phone charges when the phone battery is full) if fact I couldn't say if this was a natural side effect as never placed my ear to any other PSU!
But maybe a capacitor is going/gone duff (wild guess I know nothing about circuitry!)

Every 10 seconds the fan ever so slightly slows and speeds back up and it can only be described as hard disk clicking (lasts about half a second) at the same time the graphics card fan also fluctuates, so I'm guessing the power distribution is also been affected.

I'm all set for it been a gonner to be honest

My Rig consists of for power mainly gaming on

i7 6700k (fractionally overclocked)
Zotac 1080 amp extreme
Couple of SSD and a mechanical drive for the main of data

In future will likely change the graphics card to meet game requirments
Any advise is much appreciated as always

Thanks for the help guys
Is there any advantage to getting anything higher than 650w ?

Any of these would be a good replacement - I'd pick the Seasonic, cheaper with longest warranty.

My basket at Overclockers UK:

• 1 x Seasonic Focus Plus 650W 80 Plus Gold Modular Power Supply= £89.99
• 1 x EVGA Supernova GS 650W '80 Plus Gold' Modular Power Supply= £94.99
• 1 x Super Flower Leadex II 650W 80 Plus Gold Modular Power Supply - Black= £99.95

Total: £296.03 (includes shipping: £11.10)

Quite fancy the

This worth the extra few quid?

Seasonic has 80+ Platinum PSU for £10 cheaper.

Anyway difference in effiency is very small between Gold and Platinum.

Thanks for your help

Higher than 650w only for futureproofing/overclocking - the rated wattage actually drops slightly per year as the capacitors age, and the efficiency of the PSU drops under lower load.

Now you said that I'm thinking

Last question I promise
Need to get order in before cut off!
Is there any major advantage to the prime range?
Or focus best option?

@Blackhorse

focus plat version on sale. damn good warranty and build quality

also, since you liked bequiet, there new modular and wire-free model is out- but you do pay the price for a £20 silent wing fan and internal wire free design. compared to your older model- bequiet switched to FSP to make the units .

My basket at Overclockers UK:

• 1 x Seasonic Prime Ultra Gold 550W 80 Plus Gold Modular Power Supply= £99.95
• 1 x be quiet! Straight Power 11 550W 80 Plus Gold Modular Power Supply= £105.95

Total: £217.00 (includes shipping: £11.10)

Thanks for your help
I've ordered the

Hoping I made it in time for delivery tomorrow
Been at work all day and first chance I've had
Was nervous on the 550w whether that would cope in 5 years time
Also reviews I've read say the only negative thing about the focus range is the slightly smaller fan can cause it to spin faster and louder to keep up to the slightly larger counterparts on the prime model

Thanks everyone for their help
