Power supply just died on me, need help

msattam · May 21, 2015

So my Power Supply died on me after a month for reasons that are unclear. I was plugging it into an extension hub, could that be it? It said it was grounded...Maybe my PSU didn't have enough watts for my rig?

Here is my rig:

GTX 970 (MSI Gaming)
Asus Z97-A motherboard
i5-4690k (no overclock)
G.Skill Ripjaws X Series 8GB (2x4 GB)
Corsair 200r Case

My power supply was the XFX TS 550W PSU, a well-trusted brand in XFX and 80+ Bronze. I was told this was enough for what I have above by people on tomshardware. Is it, though? Should I go up? I can RMA and get the same 550W PSU or I can just go buy a new one. What do you guys suggest? I want a very reliable PSU. I thought I was getting that with my XFX TS. This is extremely frustrating.

It is absolutely enough power. ...and should still be under warrant. XFX is a very good and reliable source for a power supply. You may have received a bad unit, but don't let that sway you to another manufacturer. XFX or Seasonic is the only way to go (IMHO).

I'm thinking of getting the EVGA supernova GS 650W and just RMA'ing for my money.

550W is more than enough power for your rig, that is not the problem. That setup will not pull anywhere near 500W from the wall when under load and overclocked, (I have almost the same setup). My coming explanation may seem tedious and trivial, but it adequately answers your concern that "I thought the TS-series was good, so why doesn't it work?"

Now, let me explain a couple of things, Sir. As you know XFX are very credible in the PSU market. Why? Because XFX exclusively uses Seasonic as their OEM. Seasonic are renowned for their consistency of quality - they would rather make fewer PSU's of superior quality than more PSU's of inferior quality.

However, we can never draw any general conclusion, say: "Because of Seasonic's well-received image and credibility, I will never receive a faulty product from Seasonic or XFX."

Unfortunately, we cannot say that. What we can say is: "Because of Seasonic's well-received image and credibility, the probability of receiving a faulty product is low."

You probably received a faulty unit. That sucks. However, it is almost like playing poker. You know with AK, you can play aggressive because on average you'll win more than you'll lose. Thus, if you lose with AK, or anything of that order, you'll be justified in playing the exact same hand the exact same way, even though you just lost, because on average you'll win more than you'll loose.

It's the exact same thing here. The probability of receiving a faulty Seasonic unit is so small, that when it happens, the best bet is probably to buy the same unit again, as the probability on average of receiving a faulty product again, is extremely improbable.

My suggestion of very trusted brands:

Super Flower
Seasonic
Delta Electronics
FSP
Enhance Electronics

Thanks for the lesson on playing percentages. How long will it take to RMA this thing then?

Ironically, the new GS-series from EVGA is also made by Seasonic, as is the TS-series from XFX. Both are recommendable. By the way, absolutely no reason to buy above 550W. If you are adding a new GPU in the future for a SLI configuration then buy a 750W. There is basically no reason, to buy in between.

There's a 10 dollar difference between a 550W EVGA GS-series and a 650W EVGA GS-series. Head room would be nice right?

[strike]lol, didn't know that. That sounds ridiculous.[/strike] thought you said a 1 dollar difference, 10 dollar seems reasonable Get whatever of the two you'll like, the GS-series is recommendable. A 550W will be perfect for your system, a 650W will obviously work as well. With 550W you do have head room. Your system will never draw 500W from the wall when overclocked and under load. You'll have at least 75-100W of head room, in the most extreme case.

Good day, Sir.

Yeah sorry, I mistaked the G1 and the GS. There's a 1 dollar difference between a 550W GS and a 650W G1. But in that case, should I just RMA and get the XFX TS 550W 80+ Bronze again? I don't know if I want to stay at Bronze.

Well the certificate is not a measure for quality but efficiency. In other words, getting a Gold PSU does not guarantee quality, it just guarantee that the topology design is as efficient as possible.

Now, I will link you a list, and any PSU on this list, will satisfy your needs and on average last you many, many years:
