Which PSU is better?

[LTTFan16538228]

Hiya,

I am picking out a PSU for my sister’s PC that she is gonna get for Christmas.

I have calculated the power budget of the system that I am going to build for her and it is right around 400watts (i5-2500k, R9 270)

I have 3 choices for 3 PSU companies I can sorta trust:

https://www.alza.cz/seasonic-eco-430-t3-80plus-bronze-sleva-d5258613.htm Seasonic ECO-430

https://www.alza.cz/be-quiet-system-power-9-400w-d6548832.htm  Be Quiet! System Power 9 400W
https://www.alza.cz/asus-tuf-gaming-450b-d6285244.htm ASUS TUF 450B

 

Which one is better, and if none of them are any good, should I go used?

Thanks in advance to anybody who replies

The system power 9 is the best unit here in terms of quality.

Even if it's ok now, only getting a 400W PSU means that you'll have to change it as soon you upgrade to more modern components, which is kinda waste because a PSU can last for very long (my old Corsair CX600 from 8.5 years ago is still working), so you could save money by getting right now at least a 600W PSU

I tried to keep this post nice and short, but my sister only has around 160 euro/USD to spend for this PC. I have the CPU, RAM and GPU already, so what we need is a low end Dell Optiplex 390, The PSU and some peripherals (she wants to join the PC master race). So the budget is TIGHT and I think we can compromise on the wattage of the PSU for now, and then we can sell the PSU in case of an upgrade (probably in the next 2-3 years).

Ok, my advice holds only if you can afford getting a better PSU...

But if you use a Dell Optiplex you WON'T be able to fit a standard ATX PSU, you NEED Dell proprietary crap like this :

I have built in the Dell optiplex before, and I know for a fact that the 390 has a standard 24-pin. In fact, I am writing this on my Optiplex 390 with a standard PSU with no adapters whatsoever.

I don't agree. SP9 400w has a 230v only, double forward + DC-DC from HEC vs a decent full range LLC + DC-DC from Great Wall for the Asus. That makes the Asus a lot better.

So you think the Asus is gonna take the cake from each aspect?

Except fan noise. The be quite! is more silent but that doesn't make it the better unit.

Oh ok. I was thinking of settling with the SP9 because my sister’s budget might change, and we still have to squeeze a decent monitor, a low end Optiplex (we are gonna upgrade it) and an SSD into the budget of 160 USD. The SP9 was in the low end-mid range of the LTT PSU tier list, but we are gonna see.
