Power supply issue

in Hardware

I'm having trouble with my power supply, it probably isn't a very good one to begin with, i got it from a friend when i built my second rig. If i run the system in power saver mode and play games im fine, But if i run in balanced or high performance settings when i run a game, the pc shuts down soon after.

i get what im thinking is either computer lag, or my video card just isnt getting the power it needs to run the game.

The power supply is a Diablotek Phd series 850 watt power supply

The video card is a hd 7870 and it runs everything fine on max until the comp shuts down.

If it is my power supply i want to replace it this weekend, what a good/best option to go with

 

Thanks in advance

    Oh boy... I think an orange popsicle is better than Diablotek. You really shouldn't even turn on your computer again until it's replaced.

    I hope it didn't break anything else in your computer.

    With a 7870, you could probably go as low as 500W and be perfectly fine; 600W is the sweet spot that runs nearly everything. Corsair is a safe brand name, but it usually has a price premium associated with it.

    Personally I use XFX Pro but I hear Seasonic are very decent too. I would look for some benchmarks that measure voltage variation blah blah. It's the item you really shouldn't stint on.

    There are very few review sites that are actually capable of adequately reviewing a power supply. Most can tell if you the box it came in was pretty, and if it turns on and off correctly, and that's about it. But to really test a power supply, it takes some expensive, not easy to use equipment.

    I trust HardOCP reviews, they use the correct equipment, and they put the PSUs through hell in some very punishing tests. If a unit passes a HardOCP test, it's a good unit, even if it doesn't win one of their awards. They aren't the only place that does good reviews, but they are one of the few.

    I doubt i go under 650w and i was looking at the corasair tx series, just not sure yet.

     

    im gonna check the hardocp site also, thanks for that

    I used the SilentPCReview site a few years ago for ideas in a build. One of the things they focus on reviewing is PSUs. They're a very trustworthy site. It's one of the reasons I've only used Seasonic or Corsair (many of theirs are also made by Seasonic) PSUs for years.

    Here's a link to their PSU page: http://www.silentpcreview.com/Recommended_PSUs

    My recommendation is that, if you can afford it, get more power than you currently need. I've had the same Corsair PSU now in 3 successive builds over a 5 year period.

    The issue isn't the number on the label.  It's how much power the power supply can actually deliver in the real world while staying in spec.  For your current power supply, the latter is likely 0 W.

    With the promo code, this is $70 before a $10 rebate:

    If you can afford a Radeon HD 7870, you can afford a decent power supply.

    The danger of a bad power supply isn't that you might have to replace the power supply.  It's that it will fry other hardware and you might have to replace a bunch of other hardware that costs a lot more than a good power supply would have.

    thanks for the responses guys, i was in the store shopping for one when i got your response quizz and they didnt sell seasonic.  i ended up going with a corsair hx750. only went that high because it was the best deal, got it for around 120 $  and the 650 would of came out to 129.

    Paying more than you had to to get a very nice power supply like the Corsair HX750 sure beats frying hardware on a piece of junk power supply.  I just hope you haven't already damaged something else.
