Cheap PSU Performance Question

Jeff Kaos · Nov 6, 2016

I'm upgrading my gaming system to a higher end i5 6600K/GTX 1070 setup and I'm trying to save as much money as possible. I'm wondering what sort of performance issues I can expect if I don't upgrade my PSU. Right now my PSU is a generic 500 watt unit that came with my current setup from Cyber Power Inc. If I upgrade my system, which looks like it will use about 375 watts, and keep my PSU will I see any performance issues? I'm not really familiar with how PSU's affect performance, if at all, so any info will be appreciated.

With a Cyber Power generic PSU , your build is at risk , that is the last place to save money on.

It would work in theory but longevity of the ENTIRE SYSTEM is at stake if you do.

I agree. It's not worth the risk of destroying your new hardware just to save a few dollars by not upgrading the PSU.

I usually recommend the Seasonic M12ii 520W Bronze EVO Edition for builds like yours when on a budget.

Worst idea ever. Don't risk your expensive new build with a crap PSU.
This is a good deal: http://www.newegg.com/Product/Product.aspx?Item=N82E16817151096&nm_mc=AFC-C8Junction&cm_mmc=AFC-C8Junction-PCPartPicker,%20LLC-_-na-_-na-_-na&cm_sp=&AID=10446076&PID=3938566&SID=

Looking around this forum I'm starting to see that. Looks like I'll be spending an extra $70 or so on a better PSU.

Hlsgsz :

Thanks! I just ordered that one. Looks good for the price.

Dark Lord of Tech · Nov 6, 2016

Better deal on the SEASONIC G 550w I posted $59.00

And it's compatible with CPU sleep states.

Hlsgsz · Nov 6, 2016

Jeff Kaos :

Very good. Just disable C6/C7 states in the BIOS in order for sleep mode to function properly.

Dark Lord of Tech · Nov 6, 2016

The G IS THE BETTER PSU , but S12II IS still a decent choice.

Hlsgsz · Nov 6, 2016

Agreed. I posted it as the cheapest i could find that i would go for.

MrCrazy0ne · Nov 6, 2016

Just dont buy a cheap ass psu, or (in my case) a long ass psu because i cant fit this fucker in any case

Jeff Kaos · Nov 6, 2016

Lol, actually I changed my order to the one you suggested. I prefer gold rated PSU's and I don't want to hassle with BIOS to use sleep mode because I use it ALL the time.But thanks to everyone for squaring me away on my PSU dilemma. If it wasn't for the need to buy a new OS I'd probably just rebuild a new gaming rig from scratch but I already have a fairly solid storage setup as well a decent case.
