Should I upgrade PSU? If so, which one to get? Low budget

lightingft · Oct 25, 2015

Hello guys, I need some help. Should I upgrade my PSU? I currently have an Energon EPS-750W and I'm having performance drops, and everything seems fine.. Could it be my PSU? If so, should I upgrade?

Is the Cooler Master THUNDER-series 500W good? I'm looking to it. My budget is about 50-60€.

My specs:
Intel DP67DE
Intel i7-2600 @ 3.4GHz
MSI GTX970 4G
8GB RAM

Power supplies included in case are poor.

That power supply is really poor quality.

Alright, thanks, are there any cheaper alternatives? I'm not looking for the best possible, but rather a sufficient option that would handle the specs well. I'm only playing on 1080p, btw.

Also, does power supply quality affect performance greatly? I'm getting way lower FPS than average and only 50% power usage with 99% GPU Usage on most games.

You can also look at the XFX 550W 80+ Bronze if you want to stay closer to 50-60€, it is also a very good quailty PSU made by Seasonic.

And to answer your question, no, the power supply won't have an affect on your FPS in-game. If you are getting 99% GPU usage it means your graphics card is bottlenecking and at the limit of what it can perform.

I wouldn't think it would be your psu, your rig shouldn't come close to 750 watts.

Dark Lord of Tech · Oct 25, 2015

But the PSU is very poor quality , should be changed out.

My suggestion is FSP Fortron HEXA 500W. It is actually a 550W PSU. Those 500W are the pure output.

Dark Lord of Tech · Oct 25, 2015

FSP Fotron isn't very good.

How about the Cooler Master THUNDER 500W?

glamdringfh · Oct 25, 2015

That really isn't a high-quailty PSU either. Were you unable to find the XFX 550W in your area?

glamdringfh :

Yes, sadly it's not available in Lithuania

glamdringfh · Oct 25, 2015

Ok, since you have a very specific market available to you this is probably your best course of action:

Here is a link to the current Tom's PSU Tier list below. You'll want to try your best to find a PSU in your area from the tier 1 or 2 lists (500-550W units would be fine for your build). If you simply cannot afford a PSU from tiers 1 or 2 then go down to 3, though that obviously isn't ideal.
