If in Europe, sometimes you can find the same PSU available from different manufacturers for less. These are built on the same GB Bronze Seasonic platform as the Seasonic S12 I recommended above ... not because it's cheap but because it's great for that price as the jonnyguru article attests/. However, the S12 is the cheapest on amazon UK (see archaic's link) but that may vary depending upon where you shop.

I'm gonna assume that's a 750 Ti

http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-750-ti/specifications

Thermal and Power Specs:
95 C = Maximum GPU Tempurature (in C)
60 W = Graphics Card Power (W)
300 W = Minimum System Power Requirement (W)
Click to expand...


Anything below 520 watts just isn't worth getting
$54 - https://pcpartpicker.com/part/seasonic-power-supply-s12ii520bronze

The Antec HCG and XFX TS are virtually identical but usually cost much more. All three are made on Seasonic GB Bronze platform.

The EVGA B2 750 is way more than you need but it is cheaper

The following link is a good power calculator. If you come up with power between to unit's ratings always get the higher rated one. The ratings are the MAXIMUM power rating and you always want that to be higher than your required power. The difference is called "headroom" and more headroom results in less stress on the PSU.

Just as important, maybe more so, that the wattage rating is the quality of the PSU. Remember that the Gold, Bronze, etc. branding is about efficiency - not quality. The following link ranks PSUs by quality.
http://www.tomshardware.com/forum/id-2547993/psu-tier-list.html

Don't go cheap on the PSU. Everything in the box depends on clean, stable power. A poor quality PSU can fail and damage other components when it fails.

No... the CX has taken on the meaning of "Crappy Capacitors"

The calculator above is a good way to familiarize yourself with how hings add up ... eventually you will come to understand that in 99.5% of builds, the process is much simpler. Essentially the GFX card will determine your PSU size and the simplest way to get that is direct from the manufacturer a sin the link below. Another source is Guru2D which tests the power drawn by the system "at the wall'.

The data from both sources has been copies here:

I am less enthusiastic about tier lists as I have seen too many errors.

1. A great review of say a "Badass 1050SP" usually winds up with the entire line from 550 to 1050 on the same tier. The reality is that the 850 - 1050 may be made by one OEM and the 650 and 750 from another leading to very significant differences in quality and performance.

2. Even within the same OEM, you can see substantial quality / performance differences. The Corsair HX series is a good example where the higher wattages paled next to their smaller siblings.

3. A manufacturer may switch OEMs mid production run with either the former or the latter being the better unit.

So while tier lists are a good way to "get in the ballpark" or "narrow the field" so to speak, I would suggest finding a review for you specific model and wattage if possible before making a final decision.
