Is it a PSU bottleneck

[Goku Kakkarot]

My Config:

MOBO: GA-78LMT-S2 rev1.2
CPU: FX-6300 Black Edition with Cooler Master TX3 EVO
GPU: Sapphire r9 270x 2GB BF4 edition
RAM: 4GB Simtronics @1600Mhz
PSU: Corsair VS550

I want to know my overall power consumption

Games are laging im playing @1366×768 resolution

Assassins creed iv on max with 2x msaa running smoothly at 25-60 FPS.
as far as i know is should be getting 45 min in 720p?

So is it a psu bottleneck or RaM :/

How do i know if psu is bottlenecking?

Only 4GB RAM can certainly be a problem with most semi-recent games. Nothing will save you if your system needs to use the swapfile or reload stuff from SSD/HDD instead of disk cache.

A power supply "bottleneck" would usually cause the power supply to shut down from tripping over-current/over-power protection. You either have enough power or you don't and when you don't, the symptoms are rarely subtle.

if everything is stock a 350W PSU will cover it, so your 550W is fine. I would say a minimum of 8Gb of ram total should be in a computer for gaming now a days. Also try overclocking your cpu to see if that helps a little.

Everything is on stock. I didntusnderstand the symtoms of a psu bottleneck :/

And ive a wd 1tb hdd

The most common symptom is simple: your computer shuts down or reboots. There is also the possibility that the PSU will blow up. None of these are subtle.

GPUs have no way to know how powerful your PSU is, they just draw whatever power they need to get their job done. If that exceeds the PSU's capabilities, the PSU shuts down or blows up. There is also the possibility that a power quality monitoring chip in the system might decide that voltages are too far out of spec and decide to pull the system reset line low, rebooting the PC. There is no progressive loss of performance, power is usually all or nothing.

Thanks alot InvalidError!!

one more thing my system hangs most of the time when i exit some games like ACU Dying Light Watch Dogs.. But for sone seconds 20-30 i guess ... i think it is because of the ram

If the OS had to dump most of the OS and background processes into the swapfile to free up as much RAM as possible for the game, it could certainly take a few seconds for the desktop to come back to life when you exit the game.

I was considering this too as a psu problem lol.
Thanks anyways ill buy another same stick

If you were running single-channel with 1x4GB, that's another 10-15% performance penalty there from only having half the memory bandwidth the CPU can normally have, on top of all the swapping lag due to having only 4GB RAM.

 

[Goku Kakkarot]

So an another 4gb ram will definitely give me performance boost?

Swapping lag due to low RAM during a game would certainly ruin your chance of maintaining stable frame rates no matter how fast your other components are.

My ACIV always show minimum 25 fps whatever i do wirh the settings like lowering the resolution... It is also the ram problem?
And cpu never get to have much stress i think bcoz of the ram?

You will see once you put another 4GB in. More RAM is the simplest cure for chronic swapping lag.

Cool man
