The PSU listed is just a placeholder, I would like to go for the seasonic 520w fanless if it is sufficient

 

[Andythe Random]

I would really like to go for one of these if they are enough.

My basket at Overclockers UK:

• 1 x Super Flower Golden Silent 500W Fanless "80 Plus Platinum" Power Supply - Black= £129.95
• 1 x Seasonic 520w FANLESS '80 Plus Platinum' Modular Power Supply= £144.95

Total: £286.00
(includes shipping: £11.10)
​

​

If I really do need more then one of these:-

My basket at Overclockers UK:

• 1 x Corsair RM Series RMi 850 '80+ Gold' 850W Modular Power Supply (CP-9020083-UK)= £159.95
• 1 x Super Flower Leadex Platinum 850W Fully Modular "80 Plus Platinum" Power Supply - Black= £124.99

Total: £296.04
(includes shipping: £11.10)
​

​

in eco mode, with the idea being that the draw on it would not be high enough to get the fan spinning (most reviews for these have fan spinning up around 500W)

leaning towards the Super flower leadex, because it is on offer.

Nope, not on the drop down.
I was just going to try my luck, ask them if they would swap it out and hope they would want to make the sale enough to do it.
