Power Supply can handle the Power supply

Solution
For a system using a single Radeon R9 270 graphics card AMD specifies a minimum of a 500 Watt or greater system power supply. The power supply should also have a maximum combined +12 Volt continuous current rating of 28 Amps or greater and have at least one 6-pin PCI Express supplementary power connectors.

20amps * 12v rail = 240 watts

that power supply will not work and at worst it could blow your whole system if it does not have OCP

oops I mean r9 270 :)

This is my current PSU now:

Am I require to replace it to handle R9 270 or it is enough?

good protection

Heavy-duty Protection, including OVP (Over Voltage Protection),
UVP (Under Voltage Protection), OCP (Over Current Protection),
OPP (Over Power Protection), SCP (Short Circuit Protection), and
OTP (Over Temperature Protection)


and 40 amps on the 12v rail so that is 480 watts capable of going to the GPU

500W @ +50C so you will get all 500 watts even under heavy gaming

more than enough and evga good with warranty

The 500B will probably be fine, though I would recommend a good quality 550w psu just so you're running in the optimum wattage range in terms of efficiency. On the tiered list (http://www.tomshardware.co.uk/answers/id-1804779/power-supply-unit-tier-list.html) it's a Tier 3, so it's not the best but won't blow up like your current PSU.

If there is something from Tier 2 Class B or higher at 550W or higher in your price range then I would recommend that rather than the 500B

well this power supply did pass at 550 watts also so it could still be a bronze 550 watt (same efficiency rating at 500 and 550watts)

anyways efficiency rating means nothing other than power savings at the outlet (lower electricity bills)

I wouldn't say it means nothing, maybe I didn't word what I meant correctly. What I meant was that it's better to run at say 75% capacity on a PSU than it is to run at 95% capacity, simply for the longevity of a PSU. When you factor in that when PSUs age, their rated wattage can drop (as well as efficiency), meaning that this 500W unit may only be able to supply 450W in a few years time. This is one of the reasons I suggested a good quality 550W unit. Maybe EVGA has badged a 550W unit as 500W to combat this issue, I'm not entirely sure.

OP, on PC Part Picker, the 600B is only $15 more than the 500B. If you have the extra $15, I would recommend getting the 600B (http://pcpartpicker.com/part/evga-power-supply-100b10600kr).

If you live in the UK, the 600B is around £8 more than the 500B (http://uk.pcpartpicker.com/part/evga-power-supply-100b10600kr)

Thanks for the answers guys, really give me an idea what to buy
I think I'll go for 500B, I'm in tight budget if I'm going to purchase the r9 270. I live in Philippines and I think the price is here are higher compare to US or UK
