Could my poor psu have caused a bad system failure?

[Mercian]

I had a bad system failure a few days back that left me temporary unable to boot windows 7 until I could get my hands on a recovery disk. I was playing Dragon Age Inquisition on an I5 750 and a gtx 960 on very high settings, all was going well. Then the game started slowing rapidly, not in terms of fps but in terms of speech/movement being stretched and distorted, the failure followed. I did not get the details of the bsod and cannot find the log(I have looked thoroughly.) I suspect it may have been caused by loose RAM as I had recently moved the PC but on checking I noticed the PSU was a very generic 375 watt enclosed unit, much like you get on a low spec OEM. I have seen these two PSUs at PC World.

I know I can get these cheaper or a better unit at the same price but PC World is very convenient for me being 5 miles away and I am willing to pay the extra.
Anyway, would you recommend either of these PSUs for my system and could it help any further potential stability issues?
Thank you.

P.S My cpu and gpu were running at base clock speeds.

None of the power supplies they have there are any good. They only carry 12 models of 2 brands. Low end Corsair and low end Cooler Master. You need to look elsewhere. The rm750 and 850 are ok but you don't need anything that powerful.

xfx line of power supplys are rebranded seasonic units.

Thanks, I will look for different psu options. Can anyone tell me that if a poor supply can cause the problems I have listed above?

It's not possible to say with certainty if your PSU caused the problem without testing it, but, it is underpowered and OEM supplies are generally not very good quality, making the PSU very suspect. If you can find an alternative place that's acceptable for a PSU purchase, we'd be glad to give another recommendation. A 450-550 watt PSU from a high quality manufacturer/seller such as XFX, Antec or Seasonic would work well in your system.

So an Antec VPF550 550w ( £47.92 inc. vat ) would work?

 

[Archaic59]

Yes it will work. The VP550F is a lower budget unit made for Antec by Delta and is a decent quality unit that meets the requirements for your system.
