What size PSU do I need

[Ryarwood99]

I have a 550W and just used a couple calculators to see of that was enough and some said yes some said no.
CPU: i7 4790k
GPU: R7 260x
Mobo: AsRock z97 anniversary
Memory: 2×4GB ddr3
120GB SSD
1TB 7200 HDD
Some LED 120mm fans

No overclocking... And please don't make fun of build, I know the GPU CPU matchup is poor but I got a really good deal on CPU and bought it after GPU.

Thanks!

Id go 600W to be safe. By the way what brand is the PSU. You always want a bit more than enough , PSU's loose some power as heat so yea.

That should be fine, although I would like to know the exact model of the PSU. Some are made better than others, LOL. But is this a 3-year-old PSU? If it is, I would just get a new 600-watt one.

Make sure you get a high quality PSU! That is the most important! http://www.tomshardware.co.uk/forum/id-1804779/power-supply-unit-tier-list.html
After that I would recommend grabbing a 500-750w PSU. Basically you dont want to go under 500w as in the future you won't be able to upgrade and you don't want to go over 750w as it would be overkill for most upgrades. To be honest you can't really have "too much" voltage so just go with whatever you can afford between 500 and 750 in tier 1 preferably.

I have a xfx ts550 80plus bronze and it's less than 6 months old

Yes quality matters a lot. Avoid any Corsair CS/CX series they have very poor capacitors. I recommend Seasonic, FC, Antec and others.

Bottlenecking is referring to the instance where a component of your machine is underperforming in comparison to the other parts, limiting the machine's power. I believe your graphics card will be the bottleneck, in other words the weakest component in your system

The two components will work together perfectly well, but any lack of performance from your machine will be due to the weaker video card. Meaning in a future upgrade, if you seek to improve overall gaming performance, your video card would be the target component to upgrade, rather than the CPU

A quality PSU with a minimum rating of around 420 W would be recommended. So the 550 W PSU is more than adequate to power the system.

The XFX TS 550 PSU is a good choice!

You should be fine, then! XFX makes some of the best PSU's on the market.

Thank You

Just a reminder if you want better overall performance you should be targeting the GPU every other component is fine. Your combination will work though
