Power Supply Upgrade From 550W, Advice Needed

Silibant · Mar 29, 2014

Hey, so I've got an ASUS HD 7770 2GB GDDR5, and it overloads my PSU when I game. My current PSU is an Ultra LSP Series 550W, and I guess I need more. I'm looking at a Corsair CS600, can anyone find anything for about the same or less that gives me 600+watts?

A system with a single HD7770 only needs a 400watt PSU but your ultra is not the best, replace with this http://pcpartpicker.com/part/xfx-power-supply-p1550sxxb9 XFX quality made by Seasonic!

XFX 550w 80 Bronze http://uk.pcpartpicker.com/part/xfx-power-supply-p1550sxxb9
XFX XTR 550W 80 gold is one step better than the bronze plus modular.
A good quality 550w would suffice for a single gpu setup

Thanks for the support so far. I am with you all in suspecting the PSU is at fault, given that the longer the computer is on, the more crashes I experience in the GPU driver. So you all agree on just replacing my current one at the same voltage, not increasing voltage?

Crashes with heating card could be a faulty card, PSU fault would mean shut downs!
550watts and you could run 2 x 7770 in CF.

I RMA'd to ASUS and they just gave me the same thing again, so it's not the card. I am going to replace my PSU anyway, as Newegg says it's crap. The XFX you all recommend has 2 reviews, and one of which details it dying in a month. Any other units for the same price?

rolli59 · Mar 29, 2014

I do not go by Newegg reviews which in many cases are done by people with minimal knowledge, Here a professional review http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story3&reid=225

which do you think is better, or should the search go on?

Both are worse than the XFX http://www.eggxpert.com/forums/thread/323050.aspx

Out of stock. Recommended was this: http://www.newegg.com/Product/Product.aspx?Item=N82E16817438014
Thoughts?

rolli59 · Mar 29, 2014

Still a tier 3 budget PSU but a hell of a lot better than the Ultra.
Here I count 216 reviews for the XFX on Newegg http://www.newegg.com/Product/Product.aspx?Item=N82E16817207013&clickid=xrJTT31Er1xATDYSL0zFnQVPUkTTd2QcEXveQE0&iradid=97618&ircid=2106&irpid=79301&nm_mc=AFC-IR&cm_mmc=AFC-IR-_-na-_-na-_-na But looks like they mixed up PSU's since the new TS can not have 216 reviews.

The XFX looks good, and it's JUST within my budget. Do they make anything a little cheaper?

has great reviews, but doesn't show up on the Tier list.

is a Corsair CX 430, and has a tier 3 rating. Thoughts?

This seems really good, thanks. I'll leave this thread open for any extra suggestions for a little bit, but this is by far the winner as of this post. I can see why you made Expert in PSUs, great job. Also, do you just not talk?

Silibant · Mar 29, 2014

One other thing: can a faulty power supply cause GPU crashes? I keep getting these "display driver AMD driver has stopped responding and successfully recovered" messages, and I've reset my Windows, installed new drivers, etc. Nothing fixes it. Could this be the PSU?

Dark Lord of Tech · Mar 29, 2014

Corrrupt drivers , Heat , defective power supply , bad card can all cause this.

rolli59 · Mar 29, 2014

Agreed but expecting shut downs if PSU, had similar issue and turned out to be bad card. Can you try the card in a different computer and see if it takes the symptoms with it.

Silibant · Mar 30, 2014

rolli59 :

I'm afraid I can't, and my MOBO has 1 PCIe X 16 lane, so we may never know. All I do have for certain is that ASUS ran whatever RMA tests they have on it, and sent me back the same card. I am in a mATX case with only one fan, so that might be an issue, but I doubt it somehow, as the computer DOES blue screen and then shut off after extended use, pointing to EITHER heat OR a faulty PSU.

rolli59 · Mar 30, 2014

Well Asus sent me back ones a netbook with a broken casing that they broke repairing it and another one there was power connection problems in the plug for the adapter that had to go twice to them before fixed! It happens but is annoying to send things twice.

Silibant · Mar 30, 2014

rolli59 :

That's true, but considering A) I don't have enough money to pay for postage again and B) Eggxpert rated my PSU as a "replace immediately", I have reason to suspect it's the PSU. I'm going with a Corsair CX430, rated 9/10 by JohnnyGuru and 4/5 with 21k NewEgg reviews. Plus, with the rebate, the thing is 20 dollars, so that's a major plus. Will 430W be enough for me? Coolermaster's PSU requirement calculator said I'd need 305 watts, just wanted to verify.

rolli59 · Mar 30, 2014

Yes it is plenty for your setup. Hope it solves it but if it does not then contact Asus and demand they pay for shipping the second time around, I have done that twice as you see in my previous post.
