advise for upgrading?

[deepblue_82]

As soon as PSU warranty overs and you are getting new expensive, power-hungry parts to replace...

Over the years your 550W PSU no longer holds its max power capacity as its internal capacitors already depreciated.

jk ah.. so like that need to buy the 1k w psu.. can use for very long?
just asking is there a real need to upgrade every year?

Nope. If you notice in our recommendations we always suggest PSU wattage with enough headroom about 25-35%. e.g. System with GTX 970 consumes around 300W so we give a 500-550W PSU (with 400W+ on 12V rail). This has already taken into account the wattage loss over the next few years.

its about 5 years...since i last bought it. How long do i need to buy a new PSU after using?

is 550W sufficient for r9 cards?

Would suggest 600W minimum for Hawaii cards..
