corsair VS550 or Seasonic M12 evo 620w?

[TheEndIsNear]

this is my planned build http://pcpartpicker.com/list/NjdV4C

 

Should i go for a better quality but too much power PSU (Seasonic M12 evo 620w) or just a normal PSU (Corsair VS 550, Cooler master elite 550 v2, Aerocool, KCAS) , because i heard these arent very good.
 

the price difference here is around $20 but if it is worth it i would spend the extra. and btw those above are the only options in my local store.

M12 by 10 billion lightyears. Would you rather have a bomb or a PSU in your build?

well i just wasnt sure whether the others are that bad at all, the m12 modularity is a plus also anyways

Have a list, it helps when choosing PSUs c:

Consider something like this. It uses dual channel ram, which has considerable benefits over single channel in almost all applications, and also features an RX 480 4GB. if you have another $20 or so you can get the 8GB model as well. You can change the PSU out for the Seasonic also if you like

Does your local store have a website that shows us what have in stock and at what price?

 

Are you looking at only 500w+ PSUs? Because a system with an i3 + RX 470 has a typical power draw of <~200wDC, so a quality PSU like the Super Flower Golden Green HX 350 or Seasonic G 360w can power your system.

 

The Corsair VS550 is a low quality / low performing (electrically) unit. It's not something you would see me recommend, but if you are on a strict budget, it is capable of powering that system. Of course, the Seasonic M12II-B 620w is a superior budget unit in respect to quality, functionally, warranty length, and power output.

[WEEEEEE]

You could go with the lower wattage S12II, such as 430W, or 520W, if they are available where you live. There are also budget units made by EVGA, such as the 450/500/600B. All of these decent units that won't end up burning your house down.

Then he can get the 430W SeaSonic lol. the 500W won't struggle at all though with that build so it doesn't matter than it's "lower quality" just like the seasonic is lower wattage

The S12II isn't going to struggle either; the max powerdraw of this build is 370W, which leaves a fairly large 13% margin. The S12II is of better quality, and on average it will last longer (not to mention that it costs less on PCPP, don't know about where OP lives though).

13% isnt fairly large... thats about the efficiency of 80+ bronze. That would leave zero room for overclocking the GPU. also, PSUs efficiency is best at 50-80%

To be fair, you won't get very far overclocking an RX 480 regardless.

If the PSU says 430W on the box (and is of ok quality, aka not no-name firebomb) then it is able to supply 430W. The wattage on the box refers to the number of watts that it can supply on the DC side, not the number of watts that it pulls from the wall. If a unit is supplying 430W to the computer, and is 80% efficient, then it will pull ~540W from the wall. 

PSU's are not only 50-80% efficient. Check out this table from wikipedia: 

80 Plus test type[4]	115V internal non-redundant				230V internal redundant				230V EU internal non-redundant
Percentage of rated load	10%	20%	50%	100%	10%	20%	50%	100%	10%	20%	50%	100%
80 Plus		80%	80%	80%						82%	85%	82%
80 Plus Bronze		82%	85%	82%		81%	85%	81%		85%	88%	85%
80 Plus Silver		85%	88%	85%		85%	89%	85%		87%	90%	87%
80 Plus Gold		87%	90%	87%		88%	92%	88%		90%	92%	89%
80 Plus Platinum		90%	92%	89%		90%	94%	91%		92%	94%	90%
80 Plus Titanium	90%	92%	94%	90%	90%	94%	96%	91%	90%	94%	96%	94%

As long as the unit is 80+ spec compliant, it will have greater than 80% efficiency.

I know how 80+ ratings work, that's not what i was trying to say. I'm saying the margin between his system wattage and the PSUs output is really close, and efficiency will make that even closer

So this PSU outputs 430 watts. with a bronze rating, at 100% usage, 82% of that is actually usable. Running a PSU at 100% all the time runs it life down very quickly

A power supply takes AC power from the wall and convert it into usable DC power for the system's component's to used. This process isn't perfect, so during this AC-DC conversion, some of the energy is lost and wasted as heat. That's efficiency, and what the 80 Plus certification is based on.

 

A proper power supply will be rated at DC output, so efficiency is irrelevant in this discussion, as a quality 450w Gold unit will be able to output 450w continuously just like a quality 450wDC bronze unit is able to output 450wDC continuously as well.

 

The difference lies in how much energy the PSU is taking in from the wall. At 100% load on a 115V circuit, a 450w Gold unit will be 87% efficient and will draw around ~520wAC from the wall, while a Bronze unit (82% efficient) about ~550wAC from the wall.

I went with a asus H110m-k motherboard because i think the difference is only that it doesn't have a hdmi port and is fairly cheap. and i can use the hdmi port on the graphics card.

A dual channel 4gb ram might be good but i wanted to leave space for upgrading in the future. and also i heard for builds like this, the advantage of dual channel doens't affect much.

A Rx 480 is pushing my budget too much. if i had the money i would go for a i5 CPU first instead of a 480.

No they dont have a list on their website, i walked in to check out the prices, they dont sell EVGA PSU as those are the ones i look for first. i considered a Seasonic as they were selling it cheaper for $17 when purchasing their Case. but the sesasonic while being a reputable brand it seems like 620w is too much wattage for my build so that was where I'm concerned. i didn't want to go lower wattage than 500 as it will be too close to the actual usage which is not good in the long term?

they only have the 620w ones and they dont sell EVGA PSU, maybe they could have order for it but i prefer the m12 as it is cheaper to buy when purchasing their mAtx Case.

Ok, the M12II is a great choice. Have fun building!

You do realise the EVGA B series is equivalent to the Corsair CX 430/500/600W.

You what? You know it means 18% more will be drawn from the wall. All 430W from the PSU can be used.

Good point (I always put them slightly higher in my mind).
