Question about power supplies

Prepare to Facepalm

So, PSU's are probably the thing i know the least about. I have a rough understanding of the efficiency system and how to figure out which wattage works for a system.

However, i was at a shop today and i was about to get a 550W Gold for a friend but the guy in the shop recommended a 650W Bronze for the same price. (Looking back he was probably just trying to sell stock and played me) but for some reason i went for it.

He managed to sell me on the 5 year warranty Thermaltake has and He said that the difference in efficiency is 7% since the 650W makes up for the gap in efficiency since it has more to work with compared to the 550w.

How would that even work? Can that difference actually help the efficiency? And did i get a unit that was far worse than what i was originally after?

550 Gold i went in for: https://www.newegg.ca/Product/Product.aspx?Item=N82E16817151119&gclid=CjwKEAiA3NTFBRDKheuO6IG43VQSJAA74F77iMpYiYp10M1BPBr9rviwyXTukoKKQexrP4uAkwiOPxoCjKXw_wcB

650 Bronze i left with: https://www.newegg.ca/Product/Product.aspx?Item=9SIA7RD3GG5029&cm_re=thermaltake_650w-_-17-153-173-_-Product

Thanks guys.

don't know about the actual specs, but if those newegg prices are what you paid, you could have saved about $20 and still got a psu that was of good quality and met your wattage requirement, even a semi modular one.

atleast you got a 5 year warranty out of it though. 3 year warranties seem to be the average

Seasonic is the Superior Platform , and Thermaltake doesn't produce very good PSU's.
Seasonic is much better in terms of build quality.

user11464 :

I stated both
PSU's were the same price in the local shop. This is why i am confused.

Dark Lord of Tech · Feb 28, 2017

Seasonic G is a much better platform.

Deniedstingray · Feb 28, 2017

Is it even worth putting in a system or If it is unopened should i try and return it and switch it for the Seasonic?

Dark Lord of Tech · Feb 28, 2017

Warranty is 5 Years for the SEASONIC G 550W.

I would return it.

Deniedstingray · Feb 28, 2017

Thank you guys, im not sure what the f*** i was thinking. I will return it romorrow.

Dark Lord of Tech · Feb 28, 2017

The G 550 by SEASONIC is the right choice for sure , you won't regret it.

Deniedstingray · Feb 28, 2017

My friend does not want to return it because then we wont be able to build his pc tomorrow. I just tried to sway him for 20 minutes and he won't budge.

Is the Thermaltake at least safe to use? I have a Seasonic in my system and i know they are better. But we aren't risking the system but putting a TT PSU in it are we?

Dark Lord of Tech · Feb 28, 2017

It's SAFE to use , just not the same high quality build as the SEASONIC.

user11464 · Feb 28, 2017

any PSU other than EVGA/Seasonic will blow up in your face according to this forum... with a 5 year warranty I would be confident with it.

Deniedstingray · Feb 28, 2017

Alright, i tried convincing my friend but excitement is getting the best of him. Good to hear.

It is fair to say they are a little Bias, but it is for good reason. They try to give you the best possible components.

Dark Lord of Tech · Feb 28, 2017

There are plenty of good options out there for all budgets.

Show your buddy this. He might be excited to build tomorrow, but nearly as excited as the shopkeeper when you go back to buy yet another psu. In that video are some names I'm sure you won't recognize, but I guarantee that there is at least 1 that you will. Some thermaltake units aren't as bad, but some are. Choice is his, wait a few hours for a local swap or a few weeks for RMA, just to get the same gawd-aweful psu back.

Karadjgne :

He is new so im gonna let him do this on purpose and let it be a lesson.

He is kind of being a d*** so if he wants to do this i will just let it happen.

user11464 · Feb 28, 2017

people keep calling Corsair PSUs sh**. lol

Deniedstingray · Feb 28, 2017

Does that Thermaltake really fall under the budget category? It was 90 CAD.

Or are you just making a point?

Dark Lord of Tech · Feb 28, 2017

No the video , shows a real cheap power supply......Just a reference not to go too cheap.

Dark Lord of Tech · Feb 28, 2017

The power supplies in the video are an older model Raidmax.

Deniedstingray · Feb 28, 2017

Alright just wanted to make sure. Thanks for all the help.

Dark Lord of Tech · Feb 28, 2017

Anytime.

For me its all depend on price and reputable review. As long as the review said its fair to use, I would get the cheapest one. Last time I bought a Thermaltake SmartM 850W for $65 in Newegg (2,5 years ago), checked its passed in Hardocp and techpowerup, and its still running in my main pc now. Seasonic is a good brand, if you have no problem with the price, then you should go for it. Not all Thermaltake is good.

I checked current price, I would suggest you to get
$49.99 SeaSonic S12II Series S12II 620 Bronze (SS-620GB) 620W Intel ATX 12 V 80 PLUS BRONZE Certified Active PFC Power Supply
https://www.newegg.com/Product/Product.aspx?Item=N82E16817151096&nm_mc=AFC-C8Junction&cm_mmc=AFC-C8Junction-PCPartPicker,%20LLC-_-na-_-na-_-na&cm_sp=&AID=10446076&PID=3938566&SID=

Its almost half the price of your picked seasonic, it is bronze but 620W. I think this has better value.

Good luck
