PSU at 100% efficiency.

No one gave me the notion, I've just seen individuals buying these high wattage power supplies, trying to match the efficiency curve. I assumed there must of been a reason, and now I know why. 


People typically want to invest a little bit on the power supply, since it is essentially the back-bone of a PC.

If the PSU is some chinese sweat shop quality thing, if it blows, it will probably take down other parts with it (e.g. graphics card, motherboard, etc).


If you get a quality PSU, then you don't NEED to upgrade it every time you upgrade the system (e.g. replace the graphics card, change out the CPU and motherboard).


I purchased a Corsair TX 850 (ver 1) back in 2010/2011, and I'ved used in two complete system upgrades, and been through three major graphics card overhauls.

The power supply is waaay past it's 5-year warranty, but it still runs great (but it is due time for replacement if I want to keep the system) 

- Phenom II X6 1090T >> FX-8350 + motherboard swap

- 3x HD 5850 >> 2x HD 7970 >> 2x R9-Fury

- A bunch of fan + HDD + SDD upgrades in between

- The CPU, RAM, GPUs were all overclocked


My new build that I did this year, I opt'ed for an EVGA 850W P2  (80 PLUS Platinum).

EVGA offers 10-year warranty.

I probably won't keep it for that long, but it is runs solid for 5+ years, then it's better then buying a new PSU over and over again.


Plus, little bit higher efficiency, quieter operation, and the ability to use/make custom sleeved cables is also a nice little bonus.

No, it's not.

They just believe something they heard somewhere from somewone who didn't really know what he was talking about...


A PSU can have an effect on OC, but that is not relevant for us 'air cooling' guys, only relevant for LN2 and max/suicide overclocking.


For air cooling it doesn't matter as long as you have a decent PSU.

I assume the same can be said for Custom loops? This is what I use

If anyone would like to talk about meditation, especially that of the secular type.
Also I enjoy talking about recovery from drug/alcohol addiction.

Feel free to PM me :D

Custom loops are basically the same as air cooling/AIO in regards to the kind of overclocking. Yes, with custom loops you can overclock a lot more, but it's still standard overclock and not the extreme overclocking you do on LN2/phase change.
