Is my 600w PSU powerful enough?

I have many speculations. I feel like it might be the monitor, the PSU, the GPU, the mobo. I really don't want to rob my system of potential and i don't want to ruin the components.

I rock
Mobo: ASRock Z77E-ITX LGA 1155 Intel Z77 HDMI SATA 6Gb/s USB 3.0 Mini ITX Intel Motherboard
CPU: i5 2400
GPU: Sapphire Radeon HD 7970 (currently in RMA because i felt it was broke)
Ram: G SKILL 8GB
Monitor: 1 x Asus VE228H 21.5" Full HD HDMI LED BackLight LCD Monitor w/Speakers
Case: Nzxt phantom with 5 fans (top, 3 side, one back)

I am very paranoid atm wondering if i made wrong choices and if my performance in GW2 will suffer because of it. I had high frame rates and all, cool temperatures maxed out the card was fantastic. Till it became loud and then stopped working with the monitor. Could i be missing something? :(

The PSU would have been a better thing to list than the monitor that doesn't even run off it.

600W should be enough to run it, though without the actual PSU specifications, we dont know if that wattage is an outright lie (I have a generic that claims 550W, only 260W in the 12v rail. They included the other rails to inflate the overall wattage).


Here's a quick guide on how to decide whether to upgrade the PSU or not.

1. If its a generic, throw it out on general principle. Buy something proper.

2. Is the PSU sufficient? Research the max draw from the CPU and GPU/s and check it to the 12v rail (Voltage x Amps = Wattage). If you have +100W of headroom, should be fine.

3. If its from a good brand, but is 4-6+yrs old, throw it out and get a new PSU. Repeat step 2 on the new PSU.

4. If its new and from a good brand, should be fine.

Can you please take a picture of the inside of your case? that mini ITX board must sure look funny in a full tower case.

But on topic do what manofchalk suggests.

Edit: yeah that corsair unit will run it no problem (unless its defective but we don't really know until you get the card back from the manufacturers)

Corsair is a decent brand, and the PSU can provide 480W through the 12V (shouldn't be called a 600W). But its sufficient for the hardware you have unless its defective or very old.

well of course it looks a little off but its my first build i didn't exactly know 100% lol ;(. I guess the size is the only problem and nothing major? Sending the mobo back would make me / cry but i would if i had too. Well i played games on the card for a couple weeks. Sempt like my frames and performance in maxed settings were... well what i paid for but how do i know for sure.

What sort of issues were you having with the card that required you to send it back?

Something like the pc turning off sporadically could be a PSU issue for instance.

Well by decent I mean very good. Only better brand you could get is Seasonic. If its new it should be fine. And defective PSU's have a tendency to not turn on, so I guess it works.

rofl i know right i was like well how do i find if its defective if it... works LOL and decent i thought you meant like OK so i was like ;(. I see sea sonic are nice but expensive. I guess the higher wattage the higher the price. Was considering 700w but dont feel like RMA the power supply

It was the recent issue that made me send it back, the whole not recognizing my monitor. My laptop was able to yesterday so it couldn't be the monitor. The monitor wouldn't just STOP working i would think. It had a loud ass coil wine idk for sure what that was about. I just felt like it was broke. I mean it heated fine and the FPS from what i could tell were great. Not being able to use the monitor though? That's a pretty big issue to me
