Don't skimp on your PSU

I know it can be tempting especially on lower budget builds to squeeze out a few extra $$ by getting a cheaper power supply.

Don't do it, this is the part that is powering everything else in the system (obviously). If you are spending $400 on a GPU or $200 on a CPU then spend a little extra and get a good unit with a 10 year warranty.

Think of it this way you will be able to use the PSU for your next build as well so it's really only half the price.

Also stop eyeing that 850watt unit when you really only need 500watts.

Yes. It always irks me when people buy crap PSUs. When I built my PC, I didn't settle for anything less but the best, so I bought a SeaSonic PRIME.

People, don't ever look at consumer reviews. They mean absolutely and completely nothing.

For anyone who's reading wants to know more about PSUs, here's a list of guides compiled by Vagabond.

Here is a bunch of guides to a PSU. (Thanks, Vagabond139 )

What is your take on the Seasonic M12 II Evo's for budget builders? I've used those on $500-$600 builds before.

My next rebuild will probably be later this year and will be a Prime Ultra unit from Seasonic.

The M12 II is an eight year old PSU. It's not recommended anymore. Here's why:

  • They lack OTP protection (over temperature protection)
  • Their rated power will reduce from 100% to 80% at 50c
  • They lack C6/C7 power states
  • They lack a DC-DC converter.

For a similar price, you can get the CX or the CXM, which are far better units anyway.

Yep just commen sense. I personally believe that the most important part of a pc is the psu.

Yep pretty much. Even though I'm running a budget system, I'm getting a Seasonic 520w EVO Edition, due to their insanely good quality, and it's 50 bucks too.

Seasonic 520w EVO Edition

Actually, it's not a good PSU anymore. 6 years old, lacks OTP protection, etc. The Corsair CXM is a similar price and performs far better.

I have used it and it's Fine.

Means nothing

I have seen many people use it and it's fine.

Also means nothing

If It is not also used as a IDE, It's fine in my book.

It doesn't have to blow up to be a bad unit. Bad ripple suppression can cause the components to get damaged over time.

$50 is way too much for that. Its actually a poor choice ofr a PSU. Its a 8 year old unit that is now entry level. Sure reviews were great for it when it first came out but the PSU market has drastically changed since then. If it was reviewed today it would do significantly worse since the bar is a lot higher. Its group regulated, its performance isn't good anymore, it lacks OTP, and it it doesn't support C6/C7 power states. You can get a better Corsair CX/CXM for less.

After searching wattage and PSU recommendations from other websites, I changed my PSU to a CXM450, that better?

It's the EVO Edition, it's a new refresh. The previous version is bad, this one is great.

They are both the same on the inside and have all of the same problems as I listed above.

Non-Evo and Evo editions are IDENTICAL on the inside. Still the same 8 year old unit.

The only changes are cables, labels and fan (but nobody checked if the bearing is actually FDB either).

I will say this, if the 850 psu can be had for cheaper then the one you want get the 850 watt one. I wanted a 750 watt on newegg but the 850 was on sale so i got that instead and I payed 109.99 vs 119.99 for the 750
